## Abstract

In recent years, the development of 5G communication technology and the Internet has progressed by leaps and bounds. The combination of the Internet and traditional industries has given birth to a new form of economic and social development - “Internet +”, which has accelerated the internetization of the entire industry. The integration of Internet thinking into the development of traditional metal craft cultural and creative products has become the key to people’s research. This paper aims to study the design method of cultural and creative products based on the fusion of 5G technology and traditional metal craftsmanship. This paper proposes the basic theoretical concepts of 5G technology and cultural and creative products. The experimental results of this paper show that the current traditional metal craft form score is between 3.9 and 5.2. The category score ranges from 4.8 to 6.1, and the creative score ranges from 3.8 to 5.3. It can be seen that the traditional metal craft not only faces the problem of a single form, but also faces the problem of lack of innovative thinking. Therefore, traditional cultural and creative products have not kept pace with the times. The research on cultural and creative product design that integrates 5G technology and traditional metal craftsmanship is very important.

## 1. Introduction

Under the influence of world globalization, a wide variety of cultural derivatives around the world have entered the public’s field of vision, and cultural and creative products are particularly important among them. How to create good cultural and creative products is a question worth thinking and discussing. In modern life, human beings have never stopped exploring the design of cultural and creative products. There are usually two levels of basis for evaluating the nature of cultural and creative products. That is practical function and cultural connotation, that is, the so-called useful and valuable.At the moment when both the consumption of physical products and the experience of cultural appeals are equally important, cultural creative products are an effective way to achieve cultural collision. Traditional metal craft is an important part of Chinese traditional metal craft culture. Combining cultural and creative products with traditional metal craftsmanship has research value. 5G technology generally refers to 5G. The fifth-generation mobile communication technology is a new generation of broadband mobile communication technology featuring high speed, low latency, and large connections. It is the network infrastructure that realizes the interconnection of human, machine, and things.The innovation of this paper are as follows: (1) It introduces the theoretical knowledge of 5G technology and traditional metal technology. And it uses genetic algorithm to analyze the importance of 5G technology in the design of cultural and creative products of traditional metal crafts. (2) It expounds the genetic algorithm and the material interpolation method of continuum structure topology optimization. Through experiments, it was found that 5G technology can promote the development of cultural and creative products of traditional metal crafts.


## 2. Related Work

With the advent of 5G technology, people are paying more and more attention to 5G technology. Jakal M found that 5G technology has been the talk of everyone since the launch of the first 5G broadband service. 5G has virtually no latency and the ability to transmit large amounts of data across a large number of devices. It is designed to meet the growth of digital connectivity and data usage in today’s society. He realizes that 5G also goes hand in hand with the Internet of Things. Although the scholar realized the power of 5G technology, he did not introduce the advantages of this technology [1]. Dai X expects mobile data traffic to grow 1,000 times over the next decade. He first introduced the principles of complexity-constrained capacity design. Then, he proposed a nonorthogonal mode scheme to meet the needs of mobile users for computing and information application services. But the scholar did not propose how this model scheme can meet the needs of mobile users [2]. Frias Z found that while 5G is still in development, 5G networks are expected to provide mobile users with a “fiber-like” experience. He explores the potential conflict between regulation in the network and future 5G services, especially with regard to network virtualization. Although the scholar found that the emerging network has advantages and disadvantages, he did not make a clear explanation of the advantages and disadvantages [3]. Li A discovered that fifth-generation mobile communication networks are designed to provide high data rates, low latency and energy consumption, and better quality of service. Dynamic spectrum management represents the technology in 5G. It improves spectral efficiency based on allowing access to primary users. Channel hopping is a superior technique that provides a meeting point for dynamic spectrum management. But the scholar did not mention how to improve the spectral efficiency [4]. Sedani B S discusses the impact of emerging future fifth-generation (5G) cellular technologies on human health. This technology has three advantages of high speed, low latency, and connecting more devices at the same time. He also defines how to increase the speed with the help of low bit error rate and through different useful techniques. Although the scholar raised questions, he did not describe the impact of cellular technology on human health [5]. Zhang Z found that with the continuous development of 5G communication technology, the integration of 5G technology and vertical industries has been paid more and more attention. He will summarize the application of 5G technology in this field. He focuses on analyzing possible problems in technical standards and network security. He also put forward reasonable prospects and ideas for the integration of 5G technology and distribution network. But the scholar did not mention specific prospects and ideas [6]. The capabilities of cellular devices that Casillas R found to have the greatest impact on the future are not currently widely used. He discusses the hurdles involved in upgrading to 5G implementation. Although the scholar found that 5G is not widely used and found obstacles, but did not mention how to solve the obstacles [7], Wu T Y’s main goal is to optimize data transmission and connection between 5G base stations, as well as improve key technologies and transmission methods in 5G networks. In the simulation, he considered the extremely high-frequency band and small angle of the millimeter wave and placed obstacles in the environment for the high attenuation characteristics of the millimeter wave signal. Although the scholar set up a simulation experiment, he did not explain the data in the simulation experiment, which made the authenticity of the experiment not high [8].

### 3.1. Development of Traditional Metal Crafts and 5G Technology

Intangible cultural heritage traditional metal craftsmanship is a craftsmanship that carries the wisdom of the working people. After hundreds of years of historical precipitation, traditional metal craftsmanship has endured historical attributes. According to historical records, metal crafts can be traced back to the Shang and Zhou dynasties. It has been used to make various types of utensils of various classes [9]. The cultural and creative products of traditional metal crafts are shown in Figure 1.Figure 1
Cultural and creative products of traditional metal crafts.As shown in Figure1, when a metal is used as a design material, many performance factors of the metal itself need to be considered, such as density, electrical conductivity and thermal conductivity, yield strength, and tensile strength. Design can only be started when the properties of each metal are fully understood [10]. Familiarity with the properties, properties, costs, and processes of metal materials and their alloys can help designers choose materials reasonably. It also contributes to the economical, esthetic, and cultural value of the design. The basic situation of metal materials is shown in Table 1:Table 1
Basic situation of metal materials.

The metal material has strong texture, is not easy to be damaged, and has strong ductility. It has rich textural properties and an intense luster that can be recast after use. Its special material properties determine its versatility, applicability, and decorative value and have material advantages that other materials do not have. Therefore, it has played a central role in the fields of construction, technology, and machinery manufacturing [11, 12].Whether people establish the connection of “material consumption” between themselves and products, or make the choice of “spiritual and cultural consumption,” it is very necessary to maintain the spirit of respect and exploration of all cultures. People should believe that cultural and creative products are one of the most suitable ways to effectively achieve cultural collision [13]. The application areas of 5G technology are shown in Figure 2.Figure 2
Application areas of 5G technology.As shown in Figure2, the value of 5G is not only the upgrade plan of the 4G mobile communication network, but also the high-speed and extensive information transmission. It is also an important factor in changing the world’s economic, cultural, and industrial development. 5G is the foundation of modern high-tech development. It is a large platform to promote technologies such as big data, artificial intelligence, cloud computing, Internet of Things, and blockchain. It is an intelligent world that connects everything in human society [14].5G technology has a significant impact on the cultural and creative industries, providing higher speed and larger capacity network connections. It supports high-tech digitization and the development of various technologies. It also supports cultural, artistic, and social integration. The new technologies used by 5G-enabled cultures and innovative industries are very rich and spectacular [15]. The development of 5G technology is shown in Figure 3.Figure 3
Development of 5G technology.As shown in Figure3, cultural and creative products carry cultural attribute value, art appreciation value, commodity use value, and brand value. It can transform nonmaterial subjective concepts into objectively existing material forms and convey them in people’s lives in a visible, tactile, and sensible way. It stimulates the overall esthetic awareness needs of the user group and then achieves cultural continuation [16].Cultural and creative products are different from ordinary products. It contains cultural added value and has multiple functions. The first is the most important cultural connotation. This enables cultural and creative products to meet some of the cultural needs of users. This is also the biggest difference between cultural and creative products and other products, and the functionality is also indispensable. Under the premise of cultural connotation, audiences are more inclined to buy a practical product rather than a simple decoration. In addition, product creativity is also very critical, which is not just a product related to culture [17].Cultural and creative products need to add ingenuity and creativity on the basis of culture. This makes the cultural and commercial to achieve a state of seamless integration. In an idealized state, designers design cultural and creative products for their feelings, and consumers consume cultural and creative products because of their feelings [18]. The cultural and creative products based on 5G technology metal process are shown in Figure 4.Figure 4
Cultural and creative products based on 5G technology and metal technology.As shown in Figure4, 5G technology can bring new ideas to the achievement form of metal craftsmanship in the expression of objects. It makes the product itself flow out a simple yet rich cultural color. It enhances people’s cultural self-confidence and national pride and deepens the historical attributes of Chinese cultural and creative products. It also enriches the new achievements of cultural and creative products based on metal technology. This is the mission entrusted by the times to contemporary designers [19].


### 3.2. Genetic Algorithm Based on 5G Technology

Before the design of the metal craft model is completed, it is necessary to add support to the model. The placement of the model can affect how much support is provided. A suitable angle ensures that the bulk of the support structure is minimized, and unnecessary costs are reduced. For regular shapes (such as cuboid), it can be obtained by naked eye observation. However, for complex hollow products, it is difficult to find the placement angle of the minimum support volume without using tools. At this time, this problem can be solved automatically by computer through genetic algorithm [20].When solving more complex combinatorial optimization problems, genetic algorithm can usually obtain better optimization results faster than some conventional optimization algorithms. Genetic algorithms have been widely used in combinatorial optimization, machine learning, signal processing, adaptive control, and artificial life.The convergence of the algorithm means that the value obtained after multiple iterations should not increase infinitely, but tend to a certain value. Convergence is important for search algorithms. As a hot issue, the convergence of genetic algorithm is generally studied by stochastic theory [21]. The genetic algorithm state can be described by the distribution of random variable A in space Ω as
(1)Vt+1=Vt•Pt,where Vt represents a probability vector. Its role is to describe the distribution of the A population in space Ω.It has better performance for solving a series of nonconvex function problems in reality. As a relatively classic and common machine intelligence algorithm, GA can not only simplify the complexity of the model to solve specific problems, but also have the generality of solving, which makes its application more and more widely. When neither the fitness value of the genetic algorithm nor the genetic operator changes meaningfully with timet, the corresponding state transition matrix becomes a constant matrix. This type of genetic algorithm is called a homogeneous GA. The distribution of the population of homogeneous GA changes as
(2)Vt+1=Vt•P.If for any initial distributionV0, there is
(3)lim∑a∩a0Vjt=1.It theoretically proves the necessity of improving the homogeneous GA to ensure its global convergence. The research proves that as long as the optimal solution in the current population is saved every time, the homogeneous GA can obtain the ability of global convergence.Genetic algorithm can not only seek optimization in complex space, but also has lower requirements on search space. For example, it does not require the search space to be continuous, differentiable, and unimodal.


### 3.3. Improvement of Genetic Algorithm

Since the advent of the genetic algorithm, the research on its improved algorithm has been going on continuously. These include the following three categories.


#### 3.3.1. Adaptive Genetic Algorithm

The adaptive genetic algorithm is an improvement to the basic genetic algorithm. Through the adaptive adjustment of genetic parameters, it greatly improves the convergence accuracy of genetic algorithm and accelerates the convergence speed. The adaptive genetic algorithm can perform self-learning and self-optimization in the whole space. The adaptive genetic algorithm is shown in Figure5.Figure 5
Adaptive genetic algorithm.As shown in Figure5, in the specific operation process, the adaptive genetic algorithm realizes the adaptive adjustment of Pc and Pm by comparing the relationship between the average fitness favg and the maximum fitness fmax of the entire population. Its calculation formula is shown as
(4)Pc=k1fmax−favg.Adaptive adjustmentPm is shown as
(5)Pm=k2fmax−favg,In formula (5), k1 and k2 are proportional constants whose value is less than 1. When the population converges to the global optimal solution, it is necessary to save the optimal solution in each generation of the population.


#### 3.3.2. Microgenetic Algorithm

The search starts from a set of strings of solutions to the problem, not from a single solution. This is the great difference between microgenetic algorithm and traditional optimization algorithm. The traditional optimization algorithm iteratively finds the optimal solution from a single initial value, and it is easy to stray into the local optimal solution. The microgenetic algorithm starts searching from the string set, which has a large coverage and is conducive to global optimization. The microgenetic algorithm is repeated continuously, and a shared function is introduced to measure the mutual close relationship between individuals, which is represented bySdij. The degree of sharing is
(6)Si=∑j=1nSdij,i=1,2,⋯,n.The modified formula of individual fitness is(7)Si=∑j=1nSdij,i=1,2,⋯,n.In the parametric design of the product, the characteristic of controlling the relevant features of the product by parameters can provide a platform for the combined application of the genetic algorithm. It is to associate parameters with characteristic constraints to obtain the optimal solution under complex conditions.


### 3.4. Material Interpolation Method for Topology Optimization of Continuum Structure

It selects design variables for topology optimization, such as density and volume. After determining the design variables, it also needs to determine the design area to be optimized and the nondesign area. For example, the mounting holes of components or the force boundary are all nondesign areas.The structural design of metal crafts is one of the most widely used techniques in today’s society. With the development of social science and technology, the engineering structures that need to be designed and constructed are more and more complex. More rigorous and effective structural design methods have emerged, and the optimization of structural topology has been widely used in recent years. The material interpolation method for topology optimization of continuum structure is shown in Figure6.Figure 6
Material interpolation method for topology optimization of continuum structures.As shown in Figure6, essentially, structural topology optimization removes unnecessary elements in the structural design area, while retaining elements that play a key role in structural performance. Therefore, the mathematical model is established as
(8)S.tV≤V∗F=KUai=0,1i=1,2,⋯n,where ai is the design variable, n is the number of optimized design variables and V∗ is the volume after structural optimization.Topology optimization is very likely to have a “combinatorial explosion” problem. Then, due to the increase of variable forms, it creates difficulties for practical calculation problems. The constraints of the studied linear programming models are all less than types. Then, M nonnegative slack variables can be introduced through the normalization process. Slack variables are often introduced to facilitate solving in a larger feasible region. The iterative methods used in various numerical problems can accelerate the convergence. Therefore, this paper adopts the variable relaxation method as(9)S.tV≤V∗F=KU0≺amin≤ai≤1i=1,2,⋯n,where ai is the design variable, which takes a continuous value between amin,1. The meanings of the rest of the formula are exactly the same as those of formula (8). It incorporates intermediate densities during topology optimization.The variable density method refers to a given structural design area, according to known constraints, loads, and boundary conditions. It seeks the optimal topology that satisfies the design constraints through scientific optimization calculation. The variable density method has been successfully applied to practical engineering problems. It is the most frequently used method in the material interpolation model method. The variable density method is a kind of pseudo-density, which overcomes the disadvantages of the homogenization method with many design variables and complicated optimization calculation.There are two types of interpolation models commonly used in the variable density method. One is the solid isotropic material penalty model (SIMP). A density-stiffness interpolation model is commonly used in topology optimization problems. The model assumes that the material density is constant within the element and uses this as a design variable. The material properties are simulated by the exponential function of the cell density, in order to simplify the calculation and improve the efficiency. And the mathematical model is in the form of(10)EPaj=Emin+ajpE0−Emin.The second is the rational approximation model (RAMP) of material properties, which is in the form of(11)Eqaj=Emin+aj1+q1−ajE0−Emin,where Eq and EP represent the elastic modulus after optimization. E0 is the elastic modulus of the solid element, and Emin is the elastic modulus of the hollow element.The stiffness matrix, compliance, and sensitivity functions of the SIMP model are shown as(12)K=∑j=1nEmin+ajpΔEKj.The stiffness matrix, compliance, and sensitivity functions of the RAMP model are shown as(13)K=∑j=1nEmin+aj1+q1−ajΔEKj,where K represents the stiffness matrix of the structure and Kj represents the “unit” stiffness matrix.In this paper, the optimization results of SIMP and RAMP models are analyzed and compared, as shown in Figure7.Figure 7
Optimization results for SIMP and RAMP models.
(a)
Optimization results of SIMP model(b)
Optimization results of the RAMP modelAs shown in Figure7, under the same optimization conditions, the optimization results of SIMP and RAMP models have good similarity. By introducing a penalty factor, the relative density of the material is approached to both ends of 0-1. Only very few are at intermediate density values. However, with the increase of the penalty factor, the RAMP method has better stability than the SIMP method.


### 3.5. Checkerboard Format and Resolution of Grid Dependency Problems

Different types of elements are selected, or the same element is selected, but the structure of the grid changes, which will have a certain impact on the calculation results. If the selection of the element type is not appropriate, or the element shape is not good, it may have a serious impact on the calculation results. Often scholars add perimeter constraints to topology optimization to ensure that there is no checkerboard format or mesh dependency in the solution of the optimization problem. The added perimeter constraint is(14)P=∑k=1klkai−aj2+ε2−ε,where lk is the contact surface length of adjacent elementsiand j and ai and aj are the density variables of elements iand j. The size of the perimeter constraint value is artificially set by people through work experience design experience. Whether its value is appropriate is directly related to the rationality of the final optimization solution.Gradient descent may not be able to find the global optimal solution, but may be a local optimal solution. Therefore, the local gradient constraint method should be selected at this time. The local gradient constraint method overcomes the appearance of the checkerboard format by introducing gradient constraints on the cell density distribution. The introduction of constraints can effectively control the geometric complexity of the optimization results and prevent the appearance of slender components. The constraints are as shown in(15)∂ρ∂ai≤ci=1,2,where ai is the coordinate of the unit and cis the first-order limit parameter. The local gradient constraint method can control the optimization result by constraining the local element structure. However, this method can only constrain locally, and it is difficult to constrain the whole structure globally. Moreover, new constraints must be added in the optimization process, which increases the difficulty of optimization calculation. The calculation process becomes more complicated, and the calculation efficiency decreases.Based on a feature-preserving efficient grid denoising method, this paper proposes a new grid denoising method. It is not only efficient, but also maintains the geometric characteristics of the model well. The grid filtering method controls the checkerboard pattern phenomenon by modifying the cell sensitivity. The sensitivity filtering method also constrains the local structure like the local gradient constraint method, as shown in(16)∂f∂ρk=ρk−11∑i=1NHi∑i=1NHiρi∂f∂ρi.In formula (16), ∂ρ/∂ai≤ci=1,2 is the filter radius, and the size is half of the diameter of the smallest unit of the structure. Hi is the distance between adjacent units i and k, and ρi is the filtering area.The sensitivity filtering technique only needs to set the minimum size of the unit before optimization and then filter the sensitivity of the unit. The sensitivity filtering method does not need to add any new constraints like the local gradient constraint method and can ensure the optimal optimization results.The optimization model of the minimum compliance topology optimization problem based on the RAMP method is shown as(17)Va=∑i=1naivi≤fV0=V∗,where ai is the design variable material relative density; n is the number of structural units in the design space; and vi is the target flexibility function. The corresponding Lagrangian function is constructed for the topology optimization problem based on RAMP method, and it is transformed into an unconstrained optimization problem to solve. The Lagrangian function is shown as
(18)L=C+λ1V−V∗+λ2F−KF+λ3amin−a,where V−V∗ is the Lagrange multiplier, λ1 is a scalar, and the others are vectors. When the extreme value is taken at a=a∗, the necessary condition to be satisfied is shown as
(19)∂L∂ai=∂C∂ai+λ1∂V∂ai−λ2+λ3=0.From formula (19), it can be seen that the strain energy density of topology optimization is the Lagrange multiplier constant, where λ1 is a scale factor constant, so relative density-based design variables can be constructed iteratively as
(20)H1K=1+P1+P1−ai2uiTk0ui.The absolute value of the difference between the maximum values of two adjacent design variables is taken as the criterion for convergence. In addition to using design variables, the absolute value of the difference between the optimized objective functions can also be used as the convergence criterion. The standard formula for convergence is shown as(21)maxak+1−maxakmaxak≺ε.After convergence, the objective function of topology optimization and the relative density value of each structural unit are obtained. According to the obtained data, the final topology optimization result is generated, and the calculation process is ended.


### 3.6. Modern 3D Printing Technology Metal Forming Process

Machine tool precision casting is the use of CNC machine tools to directly cut and grind metals based on 3D modeling or existing products. Due to the technical limitations of the machine tool itself, such as less axial direction and tool selection, the machine tool is generally used to make products whose machining shapes are combined with each other based on basic geometry.3D printing technology is a preforming technology. It builds model structures by laminating printing and adhesives such as powdered metal and plastic. 3D printing technology has gradually matured, and 3D printers can directly print finished products. The 3D printing technology is shown in Figure8.Figure 8
3D printing technology.

Castable wax resin(b)
Castable resinAs shown in Figure8, 3D printing technology increases efficiency. Its one-piece feature can be used to optimize the structure of complex components. This thus achieves the advantages of reducing weight, increasing service life, and improving performance. Metal casting technology has a long history and has been a traditional processing method in the metal industry. Before the use of 3D printing technology, traditional wax blocks were carved by hand. As far as the author understands, the processing method of hand-carved wax in the metal processing industry is still in use. However, due to the promotion of 3D printing technology, the demand for traditional wax carving has also decreased a lot. The stencil master’s job was replaced by a 3D modeler. Traditional hand-carving wax is used in the process of welding wax trees and pressing wax molds.Despite thousands of years, many excellent and exquisite metalworking techniques have been lost for various reasons. But the preserved craft is still worthy of study by modern metal artists.

The adaptive genetic algorithm is an improvement to the basic genetic algorithm. Through the adaptive adjustment of genetic parameters, it greatly improves the convergence accuracy of genetic algorithm and accelerates the convergence speed.

### 3.3.2. Microgenetic Algorithm

The search starts from a set of strings of solutions to the problem, not from a single solution. This is the great difference between microgenetic algorithm and traditional optimization algorithm. The traditional optimization algorithm iteratively finds the optimal solution from a single initial value, and it is easy to stray into the local optimal solution. The microgenetic algorithm starts searching from the string set, which has a large coverage and is conducive to global optimization. The microgenetic algorithm is repeated continuously, and a shared function is introduced to measure the mutual close relationship between individuals, which is represented bySdij. The degree of sharing is

It is to associate parameters with characteristic constraints to obtain the optimal solution under complex conditions.

## 3.4. Material Interpolation Method for Topology Optimization of Continuum Structure

It selects design variables for topology optimization, such as density and volume. After determining the design variables, it also needs to determine the design area to be optimized and the nondesign area. For example, the mounting holes of components or the force boundary are all nondesign areas.The structural design of metal crafts is one of the most widely used techniques in today’s society. With the development of social science and technology, the engineering structures that need to be designed and constructed are more and more complex. More rigorous and effective structural design methods have emerged, and the optimization of structural topology has been widely used in recent years. The material interpolation method for topology optimization of continuum structure is shown in Figure6.Figure 6
Material interpolation method for topology optimization of continuum structures.As shown in Figure6, essentially, structural topology optimization removes unnecessary elements in the structural design area, while retaining elements that play a key role in structural performance. Therefore, the mathematical model is established as
(8)S.tV≤V∗F=KUai=0,1i=1,2,⋯n,where ai is the design variable, n is the number of optimized design variables and V∗ is the volume after structural optimization.Topology optimization is very likely to have a “combinatorial explosion” problem. Then, due to the increase of variable forms, it creates difficulties for practical calculation problems. The constraints of the studied linear programming models are all less than types. Then, M nonnegative slack variables can be introduced through the normalization process. Slack variables are often introduced to facilitate solving in a larger feasible region. The iterative methods used in various numerical problems can accelerate the convergence. Therefore, this paper adopts the variable relaxation method as(9)S.tV≤V∗F=KU0≺amin≤ai≤1i=1,2,⋯n,where ai is the design variable, which takes a continuous value between amin,1. The meanings of the rest of the formula are exactly the same as those of formula (8). It incorporates intermediate densities during topology optimization.The variable density method refers to a given structural design area, according to known constraints, loads, and boundary conditions. It seeks the optimal topology that satisfies the design constraints through scientific optimization calculation. The variable density method has been successfully applied to practical engineering problems. It is the most frequently used method in the material interpolation model method. The variable density method is a kind of pseudo-density, which overcomes the disadvantages of the homogenization method with many design variables and complicated optimization calculation.There are two types of interpolation models commonly used in the variable density method. One is the solid isotropic material penalty model (SIMP). A density-stiffness interpolation model is commonly used in topology optimization problems. The model assumes that the material density is constant within the element and uses this as a design variable. The material properties are simulated by the exponential function of the cell density, in order to simplify the calculation and improve the efficiency. And the mathematical model is in the form of(10)EPaj=Emin+ajpE0−Emin.The second is the rational approximation model (RAMP) of material properties, which is in the form of(11)Eqaj=Emin+aj1+q1−ajE0−Emin,where Eq and EP represent the elastic modulus after optimization. E0 is the elastic modulus of the solid element, and Emin is the elastic modulus of the hollow element.The stiffness matrix, compliance, and sensitivity functions of the SIMP model are shown as(12)K=∑j=1nEmin+ajpΔEKj.The stiffness matrix, compliance, and sensitivity functions of the RAMP model are shown as(13)K=∑j=1nEmin+aj1+q1−ajΔEKj,where K represents the stiffness matrix of the structure and Kj represents the “unit” stiffness matrix.In this paper, the optimization results of SIMP and RAMP models are analyzed and compared, as shown in Figure7.Figure 7
Optimization results for SIMP and RAMP models.
(a)
Optimization results of SIMP model(b)
Optimization results of the RAMP modelAs shown in Figure7, under the same optimization conditions, the optimization results of SIMP and RAMP models have good similarity. By introducing a penalty factor, the relative density of the material is approached to both ends of 0-1. Only very few are at intermediate density values. However, with the increase of the penalty factor, the RAMP method has better stability than the SIMP method.


## 3.5. Checkerboard Format and Resolution of Grid Dependency Problems

Different types of elements are selected, or the same element is selected, but the structure of the grid changes, which will have a certain impact on the calculation results. If the selection of the element type is not appropriate, or the element shape is not good, it may have a serious impact on the calculation results. Often scholars add perimeter constraints to topology optimization to ensure that there is no checkerboard format or mesh dependency in the solution of the optimization problem. The added perimeter constraint is(14)P=∑k=1klkai−aj2+ε2−ε,where lk is the contact surface length of adjacent elementsiand j and ai and aj are the density variables of elements iand j. The size of the perimeter constraint value is artificially set by people through work experience design experience. Whether its value is appropriate is directly related to the rationality of the final optimization solution.Gradient descent may not be able to find the global optimal solution, but may be a local optimal solution. Therefore, the local gradient constraint method should be selected at this time. The local gradient constraint method overcomes the appearance of the checkerboard format by introducing gradient constraints on the cell density distribution. The introduction of constraints can effectively control the geometric complexity of the optimization results and prevent the appearance of slender components. The constraints are as shown in(15)∂ρ∂ai≤ci=1,2,where ai is the coordinate of the unit and cis the first-order limit parameter. The local gradient constraint method can control the optimization result by constraining the local element structure. However, this method can only constrain locally, and it is difficult to constrain the whole structure globally. Moreover, new constraints must be added in the optimization process, which increases the difficulty of optimization calculation. The calculation process becomes more complicated, and the calculation efficiency decreases.Based on a feature-preserving efficient grid denoising method, this paper proposes a new grid denoising method. It is not only efficient, but also maintains the geometric characteristics of the model well. The grid filtering method controls the checkerboard pattern phenomenon by modifying the cell sensitivity. The sensitivity filtering method also constrains the local structure like the local gradient constraint method, as shown in(16)∂f∂ρk=ρk−11∑i=1NHi∑i=1NHiρi∂f∂ρi.In formula (16), ∂ρ/∂ai≤ci=1,2 is the filter radius, and the size is half of the diameter of the smallest unit of the structure. Hi is the distance between adjacent units i and k, and ρi is the filtering area.The sensitivity filtering technique only needs to set the minimum size of the unit before optimization and then filter the sensitivity of the unit. The sensitivity filtering method does not need to add any new constraints like the local gradient constraint method and can ensure the optimal optimization results.The optimization model of the minimum compliance topology optimization problem based on the RAMP method is shown as(17)Va=∑i=1naivi≤fV0=V∗,where ai is the design variable material relative density; n is the number of structural units in the design space; and vi is the target flexibility function. The corresponding Lagrangian function is constructed for the topology optimization problem based on RAMP method, and it is transformed into an unconstrained optimization problem to solve. The Lagrangian function is shown as
(18)L=C+λ1V−V∗+λ2F−KF+λ3amin−a,where V−V∗ is the Lagrange multiplier, λ1 is a scalar, and the others are vectors. When the extreme value is taken at a=a∗, the necessary condition to be satisfied is shown as
(19)∂L∂ai=∂C∂ai+λ1∂V∂ai−λ2+λ3=0.From formula (19), it can be seen that the strain energy density of topology optimization is the Lagrange multiplier constant, where λ1 is a scale factor constant, so relative density-based design variables can be constructed iteratively as
(20)H1K=1+P1+P1−ai2uiTk0ui.The absolute value of the difference between the maximum values of two adjacent design variables is taken as the criterion for convergence. In addition to using design variables, the absolute value of the difference between the optimized objective functions can also be used as the convergence criterion. The standard formula for convergence is shown as(21)maxak+1−maxakmaxak≺ε.After convergence, the objective function of topology optimization and the relative density value of each structural unit are obtained. According to the obtained data, the final topology optimization result is generated, and the calculation process is ended.


## 3.6. Modern 3D Printing Technology Metal Forming Process

Machine tool precision casting is the use of CNC machine tools to directly cut and grind metals based on 3D modeling or existing products. Due to the technical limitations of the machine tool itself, such as less axial direction and tool selection, the machine tool is generally used to make products whose machining shapes are combined with each other based on basic geometry.3D printing technology is a preforming technology. It builds model structures by laminating printing and adhesives such as powdered metal and plastic. 3D printing technology has gradually matured, and 3D printers can directly print finished products. The 3D printing technology is shown in Figure8.Figure 8

Castable resinAs shown in Figure8, 3D printing technology increases efficiency. Its one-piece feature can be used to optimize the structure of complex components. This thus achieves the advantages of reducing weight, increasing service life, and improving performance. Metal casting technology has a long history and has been a traditional processing method in the metal industry. Before the use of 3D printing technology, traditional wax blocks were carved by hand. As far as the author understands, the processing method of hand-carved wax in the metal processing industry is still in use. However, due to the promotion of 3D printing technology, the demand for traditional wax carving has also decreased a lot. The stencil master’s job was replaced by a 3D modeler. Traditional hand-carving wax is used in the process of welding wax trees and pressing wax molds.Despite thousands of years, many excellent and exquisite metalworking techniques have been lost for various reasons. But the preserved craft is still worthy of study by modern metal artists.

## 5. Discussion

This paper discusses the impact of 5G technology on the design of traditional metal craft cultural and creative products. It describes the theoretical knowledge related to 5G technology and traditional metal craftsmanship and focuses on cultural and creative products. This paper explores the development of cultural and creative products and discusses the significance of 5G technology to the design of traditional metal craft cultural and creative products through experimental analysis. This finally found that 5G technology can promote the development of traditional metal craft cultural and creative products.This paper also studies the genetic algorithm and analyzes the genetic algorithm before and after improvement. It is found that the improved genetic algorithm can play a more important role in traditional metal processing. This improves the optimization ability of the genetic algorithm. From the experimental analysis in this paper, we can know that 5G technology not only has the functions of high accuracy and high transmission, but also can enrich the concept of traditional metal craft culture and creative product design. This makes people get their own needs in the traditional metal craft cultural and creative products.


## 6. Conclusion

In the context of the rapid development of global information, the changes brought about by 5G technology are also very large. Traditional metal craftsmanship has been widely welcomed by people for thousands of years, because it is not only exquisite in workmanship, but also entrusts people’s spiritual pursuit. However, the cultural and creative products of traditional metal crafts have fallen behind the development of the times and cannot meet the spiritual needs of consumers. Therefore, this paper studies the design of cultural and creative products that integrate 5G technology and traditional metal technology. This paper analyzes the development of 5G technology and traditional metal processes and finds that the importance of both is increasing. However, the style of cultural and creative products of a single traditional metal craft is relatively simple, and the space for dissemination is also very small. But 5G technology has brought earth-shaking changes to communications. Therefore, creators of cultural and creative products can spread their cultural and creative products through the Internet to let more people know about them. 5G technology not only enables the rapid online dissemination of cultural and creative products of traditional metal crafts, but also makes the products more colorful. In an experiment, this paper investigates the current problems faced by 10 metal craft companies with their metal wares. It was found that the current metal utensils face problems such as few styles and lack of innovation. The Internet of 5G technology can brainstorm ideas and increase people’s awareness of innovation. Therefore, cultural and creative products that integrate 5G technology and traditional metal craftsmanship are more in line with the characteristics of this era.
