Metal 3D Printing - Slm / Dmls
METAL 3D Printing - SLM / DMLS
The two technologies have many similarities: both use laser scanning and selectively fuse (or melt) metal powder particles, glue them together and build them layer by layer. Similarly, the materials used in both processes are granular metals.
The difference between SLM and DMLS is due to the basis (and patents) of the particle bonding process: SLM uses metal powder with a single melting temperature and completely melts the particles, while in DMLS, the powder is composed of materials with variable melting points at high temperatures Fusion at the molecular level.
Bering 3D provides 3D printing services for various metal materials such as stainless steel, die steel, titanium alloy, aluminum alloy, and bronze.
