Direct Metal Laser Sintering (DMLS) does for metals what other RP processes have done for
plastics, but takes it further with generally better tolerances and truly production worthy
DMLS builds parts from powdered metal in thin layers (20 microns/.0008 inches) with walls as thin as 0.2 mm (.008 Inches) and typical tolerances of ±.001 inch/inch.
A broad range of materials are available to meet a variety of real-world application requirements.
Materials include: 17-4 Stainless Steel, Direct Metal 20 (bronze alloy), Direct Steel H20 (tool
steel), Cobalt Chrome, Maraging Steel.
DMLS is best suited for small complex parts (including internal passages typical of aero investment castings). The maximum build envelope is 250 mm x 250 mm x 215 mm (9.85
in. x 9.85 in. x 8.5 in.)
The combination of materials, tolerances and feature definition available with DMLS combined
with the ability to build parts with internal passages and other geometric complexities open
up a wide variety of applications for DMLS including:
• Prototypes, short-run production, individualized products, spare parts
• Parts requiring high corrosion resistance such as medical instruments or prototype implants
• Parts requiring high toughness or ductility
• Parts requiring hardness including tooling and fixtures.
• Injection mold and casting die inserts, including conformal cooling.
• Prototypes of metal cast parts, particularly those that will require ceramic core dies for
internal passages (typical of blades and vanes, and fuel system components)
