The process chain of metal 3D printing

We have summarized all steps from preparation to postprocessing for you here.

1. Data preparation

  • CAD modelling: No component without a design template. For you, this means that you have to design the component in advance with a 3D optimised CAD software.
  • STL export: Once you have finished designing, export your model.

2. Data preparation

  • Preparation
  • Supports generation: Most components require additional supports, e.g. for overhangs or certain angles. See also the support setting options in our MPREP software.
  • Parameter selection: Each material has its own parameters, which have been developed in coordination with various factors such as scanning speed and laser power, to ensure that the powder and the laser are optimally matched to print the desired part.
  • Simulation
  • Slicing and Preview

3. Print preparation

  • Insert powder supply cartridges
  • Insert build module
  • (insert overflow cartridge)
  • Load print job
  • Inerting

5. Unpacking process

  • Take the construction module from MPRINT out and insert it into MPURE
  • Rough powder removal using gloves
  • Place the building platform on the turntable
  • Removing powder from interspaces and support structures

6. Separation of the component and the building platform

  • Separation by band saw or spark erosion

7. Post-processing of the component

  • Support removal
  • Beams
  • Surface treatment
