Finishing 3D metal printed parts

Post-processing 3D prints is necessary in order to become nicely finished components. Talking about 3D printing in metal, smooth surfaces can only be achieved by further finishing after the printing process.

As a result of 30 years of experience in metal- and laser processing, Raytech is able to provide a large number of post-processing services.

3D designing and post-processing go hand in hand

During the 3D design phase, it’s useful to keep the importance of post-processing in mind.

Support structures

During the 3D printing process, support structures are essential to connect the printed object with the building plate. Mostly, these structures need to be removed after printing. So, it’s important to print as little unnecessary supports as possible, to minimize printing time and finishing costs.

Finishing possibilities:

  • Sandblasting (dry)
  • Sandblasting wet
  • Drum blasting
  • Polishing
  • Milling
  • Laser welding
  • Laser cutting
  • Ultrasonic cleaning

Hybrid technologies

Additive manufacturing & micro laser technologies

By combining additive production methods with subtractive technologies, efficient and innovative solutions can be found.

For example, 3D metal printed components can after the printing process be joined together using laser welding. Due to the good weldability properties, mostly in titanium.(Micro) laser welding of 3D prints allows to produce complex components in an efficient and economical way.
