## 5 Future Perspectives
### Key Focus Areas for Research and Development  
Based on a systematic review of existing literature and research on actual companies, it can be predicted that the future research and development of SiC powder 3D printing technology will focus primarily on technological breakthroughs and process optimization. To drive the industrial application of this technology, key areas of research will focus on material performance optimization, process parameter matching, and intelligent formation quality control.  
First, material performance optimization is key to improving the quality of printed parts. The physical properties of SiC powder, such as particle size distribution, morphology, and interaction with binders, directly affect the surface quality, mechanical properties, and internal structural uniformity of printed products. Future research should deeply explore the impact of these factors on the quality of printed parts, optimize the pretreatment processes of SiC powder, and improve its flowability and bonding characteristics [205].  
For example, precise control of powder particle size and morphology can reduce porosity during the printing process, increase the density and strength of printed parts, and meet the requirements for manufacturing complex structures. Secondly, matching binders with printing parameters is a critical aspect of process development. Selecting appropriate binders and optimizing jetting parameters is essential to meet the diverse demands of different application scenarios and product structures. This not only helps improve the mechanical properties and dimensional accuracy of the printed parts, but also enhances the interlayer bonding strength and uniformity during the printing process [207]. Future research should focus on exploring how to select optimal binder composition and viscosity based on the characteristics of different materials, combined with key process parameters such as jetting speed and droplet volume, to develop efficient and reliable forming processes. Additionally, innovations in formation quality control technology are central to ensuring product consistency and precision in printing. As 3D printing technology moves toward large-scale production, integration of real-time monitoring and closed-loop control systems will become a key research focus. AI-based and sensor technologies can enable real-time monitoring and automatic adjustment of key parameters during the printing process, thereby improving the consistency and quality of printed parts [207]. For example, by collecting real-time data on jetting parameters, material conditions, and printed parts, feedback control can automatically adjust variables such as jetting speed and temperature to respond to potential process fluctuations. This intelligent and automated formation quality control system can not only improve production efficiency, but also significantly reduce scrap rates and production costs, advancing SiC powder 3D printing technology toward industrialization and standardization.  
Future research and development of SiC powder 3D printing technology will focus on material optimization, process parameter matching, and intelligent formation quality control. With continuous technological breakthroughs and process improvements, the application potential of SiC 3D printing technology in the manufacturing of complex parts will be further unlocked.
