Benefits of 3d Printing with DMLS Technology

Technical Metal/Products/3D printing/Benefits of 3d Printing with DMLS Technology
  • Your custom metal part can be built in hours, with no tooling required
  • Ideal for functional prototypes, high-temperature applications, and end parts
  • Cost-effective compared to traditional manufacturing methods for intricate parts
  • Can reproduce complex geometries with high dimensional accuracy
  • Parts with machined components can be manufactured as a single component
  • Inner channels and passages that are curved, such as conformal cooling channels in a tool and die, can be achieved with 3-d metal printing.

Direct Metal Laser Sintering Materials

Metal materials like you’ve never seen them before. Produce complex geometries in one fluid build that would be impossible to compose with traditional manufacturing processes. Additive metals deliver dense, corrosive resistant and high strength parts which can be further treated through heat, coating and sterilization.
