About the Process

Direct Metal Laser Sintering (DMLS) is a direct metal laser melting (DMLM) or laser powder bed fusion (LPBF) technology that accurately forms complex geometries not possible with other metal manufacturing methods.

DMLS parts are stronger and denser than investment casted metal parts, and they can help you get to market first with faster turnaround times.Metal 3D printing is an ideal process for complex oil and gas components, custom medical guides, part-consolidated aerospace parts and tough functional prototypes.

DMLS materials build fully dense, corrosive resistant and highly robust metal parts that can be further treated through heat, coating and sterilization. Utilize the design freedom of DMLS and produce accurate metal components in less time than other manufacturing methods.

+ Design for Manufacturing Tips

- Overhangs with an angle greater than 35 degrees can be built without support structures.
- Superfluous volumes should be avoided when using this technology
- Overall, the most ideal geometries are small, self-supporting parts that would be difficult to manufacture through machining
