(Summary description)With the rapid development of science and technology, metal 3D printing technology has become an important pillar of modern manufacturing. It is of great practical significance to discuss today how metal 3D printing can improve product quality and meet production demands. Here will discuss around the core keywords of metal 3D printing, stainless steel 3D printing and aluminum alloy 3D printing. First: Metal 3D Print Technology Metal 3D printing technology has been widely used in aerospace, automotive manufacturing, medical devices, molds and other industries due to its unique advantages, such as high precision, low cost and rapid manufacturing. At present, domestic and international research on metal 3D printing technology mainly focuses on materials, processes and equipment. However, there are some challenges, such as low productivity and high material cost. Second: the improvement measures of metal 3D printing technology In order to improve the quality of metal 3D printing products and meet the production demand, the following measures are necessary: Optimize the printing parameters: By adjusting the printing parameters, such as laser power, scanning speed, filling density, etc., the melting effect of the metal powder can be improved, and the printing accuracy and stability can be improved. Selection of suitable metal powder: The particle size, composition and purity of the metal powder will affect the print quality. Selection of fine grain size, high purity, and similar to the composition of the base material of the metal powder can reduce the defect rate and improve the homogeneous density. Optimize support structure: For metal parts with complex structures, a reasonable support structure needs to be designed to prevent deformation and cracking. By optimizing the support structure, the strength and stability of the printed part can be improved. Post-treatment process: Post-treatment process is crucial to improving the quality of metal 3D printing products. Through appropriate heat treatment, polishing, corrosion prevention and other post-treatment processes, internal stress can be eliminated and corrosion resistance and surface finish can be improved. Third： Challenges and prospects of stainless steel 3D printing and aluminum alloy 3D printing Stainless steel and aluminum alloys, as common metal materials, have excellent properties and a wide range of applications. However, they also face some challenges in the 3D printing process. The main challenges in 3D printing of stainless steel are cracking and deformation. Since stainless steel has a high coefficient of thermal expansion and modulus of elasticity, it is prone to shrinkage and deformation during the printing process. Therefore, printing parameters and support structures need to be optimized to reduce the risk of deformation and cracking. Aluminum alloy 3D printing, on the other hand, needs to solve the problem of low melting point and easy oxidation. During the printing process, aluminum alloy powder is easy to oxidize, leading to a decline in surface quality. Therefore, it is necessary to use aluminum alloy powder with good antioxidant properties, as well as a protective gas or vacuum environment to reduce the degree of oxidation. Despite some challenges in the 3D printing process of stainless steel and aluminum alloys, their applications are still very promising. Stainless steel 3D printing can be used to manufacture high-strength, corrosion-resistant parts; aluminum alloy 3D printing can be used to manufacture lightweight, high thermal conductivity structural parts. Now the future development of metal 3D printing technology will be more broad and diversified. Fourth: Conclusion Some measures to improve the quality of products and meet the production demand are proposed via the discussion of metal 3D printing technology. The challenges and prospects for stainless steel 3D printing and aluminum alloy 3D printing are analyzed. Under the leadership of Tianhong Laser, the application of metal 3D printing technology has a broad prospect and needs our further exploration and innovation. We hope that this paper can provide some reference and inspiration for the development of metal 3D printing technology.
