Direct Metal Laser Sintering (DMLS) - 3D Printing Technology

DMLS produces fully dense metal parts with mechanical properties matching traditional manufacturing. Complex internal geometries and part consolidation enable revolutionary design possibilities in aerospace, medical, and automotive applications.

You can find more information on our web, so please take a look.

Advanced manufacturing capabilities enable complex geometries, functional prototypes, and end-use production parts that would be impossible or cost-prohibitive with traditional manufacturing methods. From functional prototypes to end-use production parts, this technology delivers exceptional performance across demanding industries.

Powder Preparation

Fine metal powder is prepared and loaded into the machine. The build platform is preheated to optimal temperature to reduce thermal stress and improve part quality.

Layer Spreading

A thin layer of metal powder is spread evenly across the build platform using a recoater blade. Layer thickness is precisely controlled for optimal part quality.

Laser Sintering

A high-powered fiber laser selectively melts the metal powder according to the part geometry. The laser parameters are optimized for each material to achieve full density.

Tolerances

Best achievable tolerances

If you are looking for more details, kindly visit Prototype Finder.

Best achievable tolerances - <100mm: ±0.2mm, <200mm: ±0.3mm, <300mm: ±0.4mm, 300-400mm: ±0.4-0.5mm. If your parts require specific tolerances, an engineering drawing must be provided when requesting a manual quote.

Parts designed with thin, flat planes will likely warp, so this should be avoided if tight tolerances are required. Polishing removes approximately 0.1mm of material.

Surface Finish

Visible Layer Lines

Layer lines are visible on faces at a low angle relative to the build plate. Metal supports are removed, which may leave subtle marks in the surface of the part. Metal 3D printed parts are shot peened to a surface uniform roughness of 200 - 400 Ra after support removal.

Post-processing can significantly improve surface finish for critical applications.
