[Science] Current 3D printing metal advantages and processes

3D printing rapid prototyping technology has been in existence for decades, and some research progress has been made in the field of manufacturing. The performance of 3D printed metals has approached or even surpassed conventional conventional processing in some areas.

From the material point of view, the traditional conventional process uses raw liquid, solid, powder and other materials, the material itself has no special treatment;

The metal powder material used in 3D printing is specially treated and has added more constituent elements. It already has flexural strength, tensile strength, elongation, Young's modulus, hardness, tensile elongation point and thermal expansion coefficient. Dozens of indicators such as elastic modulus, melting range, corrosion resistance, and bond strength. The performance of such materials has been researched, tested, and cited, and has proven to be consistent with the requirements of structural components.

In addition, the performance improvement of the 3D printing device process is optimized, and the precision and density of metal printing are also greatly improved. Xiaobian's optimization in the powder coating process and scanning positioning technology enables metal 3D printing to achieve higher precision and complexity.
