How it Works: Direct Metal Laser Sintering (DMLS)

direct metal laser sintering also known as DMLs is an additive manufacturing technology that creates metal parts directly from 3d CAD data without the need for tooling DMLs utilizes a variety of metal and alloy materials such as stainless steel cobalt chrome and inconel to create strong durable parts and prototypes DMLs is an excellent choice for functional metal prototypes high-temperature applications and end-use parts the DMLs process begins in the same fashion as other layer additive manufacturing technologies a program takes 3d CAD data and mathematically slices it into 2d cross-sections each of these sections will act as a blueprint telling the DMLs machines exactly where to Center the metal material the data is then transferred to the DMLs equipment a recoder assembly Busch's powdered metal material from the powder supply to create a uniform layer over the base plane a laser then draws a 2d cross-section on the surface of the build material eating and fusing the material once a single layer is complete the base plate is lowered just enough to make room for the next layer more material is raised from the cartridge and recoated evenly on the previously sintered layer the DMLs machine continues to center layer upon layer building from the bottom up as the part is built support structures are added to give supplemental strength to find features and overhanging surfaces the completed part is then removed from the base play and treated with an age hardening heat process to further harden the part any support structures are also removed at this time with numerous surface treatment and hand polishing options available through service providers DMLs parts can be used in highly cosmetic applications typical uses for DMLs include tools and manufacturing aids small integrated structures dental components surgical implants and aerospace parts you
