Additive Manufacturing - Powder Bed Fusion Process with the HP Multi Jet Fusion for PA12

The HP Multi Jet Fusion powder bed fusion process allows the Mechanical Systems Competence Center to produce components in PA12. There are almost no production residual reductions to be observed. What is practically unthinkable in other processes, or can only be achieved with great effort, can here be realised without any problems. Another option is to produce parts partially or entirely in colour. The robust components in PA12 can be used directly as «end-use parts». This is a considerable advantage, especially for small series or functional samples!

How does the HP Multi Jet Fusion manufacturing process work?
It is a powder bed fusion process whereby the powder is applied layer by layer and melted locally by a heat source. The unique feature is a print head that applies an «agent» via fine nozzles in the area of the contour of the component to be manufactured. A powerful lamp operates as a heat source that melts the powder. Thereby, the applied «agent» section is s heated above the material's melting point (absorption).

Preferred data formats:

  • 3mf, with information on colours stored in the file
  • All common CAD export formats by arrangement

Maximum size:
332 x 190 x 248 mm

Layer thickness:
The individual powder layers are in the range of 0.08 mm during powder application (coating).

Construction material:
PA12

Post-processing:
After the components have been removed from the print area, they are blasted with glass beads using a blasting unit. This removes any powder still adhering to the parts. The components are then basically finished.

PA12 can also be further processed, depending on the requirements. In addition to machining, components can also be glued or coloured in an immersion bath.
