Finishing Processes for Metal 3D Printed Parts

  • May 5, 2015
    9:00 am - 10:30 am

During the Direct Metal Laser Sintering (DMLS) parts have a finish that is comparable to fine investment casted parts. But under that surface, parts can have internal stresses that could affect their performance.

DMLS is an additive manufacturing technique that fuses powdered metal together with a high powered laser to create a solid structure.

During the DMLS build process, a very small are of the part is heated to the melting point of the metal, while the remainder of the part is relatively cool. The resulting internal stresses may need to be dealt with, depending on the application of the part.

Critical surfaces of the part may also need to be machined, polished, or otherwise treated before the part is put into service.

Attend this session to learn about:

  • When to be concerned about internal stresses
  • Annealing processes for DMLS
  • Part finishing options
    • Media blasting
    • Shot peening
    • Polishing
    • Machining
