Direct metal laser sintering (DMLS) is an industrial 3D printing process that builds fully functional metal prototypes in a range of metals like steel, aluminimu, titanium etc. It allows for the direct manufacturing of complex end-use parts and facilitates tooling for conventional manufacturing technologies, reducing costs and lead times.

WHY CHOOSE THINK3D
think3D has one EOS M290 machine in-house to offer various metal additive manufacturing service. We can 3D Print various metals like Chromium Cobalt, Tool Steel, Maraging Steel, Aluminium
Metal 3D Printing is a laser-based technology that uses powdered metals. Similar to Laser Sintering, a high-powered laser selectively binds together particles on the powder bed while the machine distributes even layers of metallic powder.
The DMLS machine begins sintering each layer—first the support structures to the base plate, then the part itself—with a laser aimed onto a bed of metallic powder. After a cross-section layer of powder is micro-welded, the build platform shifts down and a recoater blade moves across the platform to deposit the next layer of powder into an inert build chamber. The process is repeated layer by layer until the build is complete.
Support structures are automatically generated and built simultaneously in the same material, and are later manually removed. An initial brushing is manually administered to parts to remove a majority of loose powder, followed by the appropriate heat-treat cycle while still fixtured in the support systems to relieve any stresses. Parts are removed from the platform and support structures are removed from the parts, then finished with any needed bead blasting and deburring. Final DMLS parts are near 100 percent dense.
This technology combines the design flexibility of 3D Printing with the mechanical properties of metal. From tooling inserts with cooling channels to lightweight structures for aerospace, any application that involves complex metal parts potentially benefits from Metal 3D Printing.

Hi
Greetings from think3D! We do provide FDM, SLA & DLP technology based 3D printers. At this moment we will not be able to procure the machines for you. However, if you need any help in producing parts using industrial technologies like DMLS/ full color/ Polyjet/ SLS/SLA, feel free to approach us.
Thank you.
