The DMLS machine begins to sinter each layer-first the support structure of the base plate, and then the part itself-with a laser aimed at the metal powder bed.
After the cross-section of the powder, the layer to be micro-welding, the build platform moves downward, recoating blade moves through the internet to the next layer of powder is deposited into an inert build chamber.
This process is repeated layer by layer until the build is complete.
After construction, the parts manual brushing to remove most of the initial loose powder, followed by appropriate heat treatment cycles, while still secured to the support system to relieve any stress.
Remove the part from the platform, remove the support structure from the part, and then perform any required sandblasting and deburring.
The density of the final DMLS part is close to 100%.
