## 1 Introduction
Furthermore, they use non-contact scanning methods, reducing the risk of damage to the scanned object. Lastly, many portable 3D scanners are compatible with various software, making data processing and integration into other systems easier [18; 19]. An alternative method to 3D Scanning is photogrammetry. This is a different technique that uses a series of photographs taken from different angles to create a 3D model and does not require the presence of a 3D scanner. The software then uses these photographs to create a 3D model by estimating the depth of the objects in the scene. This technique is well-suited for scanning outdoor environments and large structures, as well as for creating detailed 3D models of cultural heritage artifacts. One major disadvantage is the need for a large number of images to achieve high accuracy, which can be time-consuming to capture. Another issue is the difficulty in obtaining images with sufficient overlap and coverage, especially when trying to capture complex shapes or objects with reflective or transparent surfaces. Photogrammetry can also be sensitive to changes in lighting and shadows, leading to inaccuracies in the final 3D model. Additionally, the process of stitching images together and generating the 3D model can be computationally intensive and require powerful software and hardware. Overall, while photogrammetry can be a powerful tool for creating 3D models, its limitations and complexities must be considered in the planning and execution of a photogrammetry project [20; 21; 22]. Three-dimensional printing, commonly referred to as additive manufacturing, is a technique for producing three-dimensional items by layering material. This process is in contrast to traditional manufacturing methods, such as machining or molding, which involve cutting away or shaping material to create an object. Three-dimensional printing allows for the creation of complex and customized objects with a high degree of precision and at a relatively low cost. Three-dimensional printing works by depositing material layer by layer to build an object from a 3D model. There are several technologies used in 3D printing, including Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLS). The process starts with creating a digital model, which is then sliced into layers and sent to the printer. The item is then constructed layer by layer by the printer until its completion. The material used in 3D printing can be plastic, metal, ceramics, or composites, among others, and is usually supplied in the form of filaments, resins, or powders. The type of material and technology used determines the final properties of the printed object, such as strength, flexibility, and surface finish [23; 24; 25; 26]. The International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM) have jointly developed a standardized terminology for additive manufacturing processes. This terminology defines terms and concepts related to 3D printing and additive manufacturing, including key process characteristics, types of materials used, and post-processing methods. The standardized terminology helps to ensure that professionals in the industry have a common language to communicate about additive manufacturing processes, reducing misunderstandings and errors. It also allows for clear and consistent documentation and reporting of additive manufacturing activities, enabling accurate comparisons and evaluations of different technologies and processes. The ISO/ASTM terminology for additive manufacturing processes is regularly updated to keep up with advancements in technology and industry trends, ensuring that the terminology remains relevant and useful to those in the industry [27; 28; 29]. One of the biggest advantages of 3D printing is its ability to create highly customized and unique objects quickly and efficiently. With traditional manufacturing methods, creating a one-off or customized product can be time-consuming and expensive.
