What is the difference between SLS and DMLS?

What is the difference between SLS and DMLS?

“Selective Laser Sintering and Direct Metal Laser Sintering are essentially the same thing, with SLS used to refer to the process as applied to a variety of materials—plastics, glass, ceramics—whereas DMLS refers to the process as applied to metal alloys.


What is DMLS in 3D printing?

DMLS is a 3D printing process, which uses a computer-controlled, high-power laser beam to melt and fuse layers of metallic powder together. Direct metal laser sintering (DMLS) is an industrial 3D printing process that builds fully functional – rapid metal prototypes and production parts in 7 days or less.

How does DMLS 3D printing work?

How Does Metal 3D Printing Work? 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.

What is difference in supporting between metal 3D printing and SLS?

Material selection is one of the main differences between SLA and SLS printing. SLS can also use some polymers such as nylon and polystyrene. However, it can also use ceramics and metals such as steel and titanium. Another difference in material is the form.

How do metal 3D printers work?

How does metal 3D printing work? A thin layer of metal powder is spread over the build platform and a high power laser scans the cross-section of the component, melting (or fusing) the metal particles together and creating the next layer. The entire area of the model is scanned, so the part is built fully solid.

How strong is Dmls?

The alloy has excellent creep-rupture strength at temperatures to 1300°F (700°C). Cobalt-Chrome alloys are standard alloys in the medical and dental fields. Due to the high hardness, Cobalt-Chrome alloys are used to produce dental prostheses. This is also influenced by the biocompatibility of the alloy.
