Post-processing for industrial 3D printing

Automatable solutions for unpacking, de-powdering and cleaning of 3d-printed components as well as residue-free recycling of recyclable powder (e.g. SLS, MJF)

Rework of laser-sintered workpieces creates the bottleneck for the industrial use of additive manufacturing (AM).

Our solutions start here. They

  • protect your employees and the machine by keeping it dust-free.
  • produce a high, reproducible part quality.
  • require little energy and space. They also dispense with compressed air and auxiliary process materials such as cleaning agents or blasting material.
  • create a high throughput.
  • can be automated completely.

Our post-processing solutions complete the production chain around unpacking and de-powdering. This increases productivity efficiency at constant quality, which is especially beneficial for industries such as medical, automotive, and aerospace, which already operate 3D printing technology in small to large batches.

Within more or less two decades we developed an extraordinary know-how in the field of mechanic dry and wet cleaning. Production companies of most different branches rely on us worldwide: from small companies to large-sized international corporations.

Process optimization for additive manufacturing

"In order to offer our customers in the field of additive manufacturing a higher level of efficiency while maintaining the same component quality, a higher degree of automation is also necessary in post-processing.

OSSBERGER has developed an excellent solution to meet these requirements, especially for small parts and larger quantities. In addition, the powder handling is automated and thus also made safer."

1st phase: Unpacking

Powder recycling circulation

The build container with workpieces, embedded in powder, is transferred to the machine. The container is emptied layer by layer, the workpieces are unpacked and unstacked under gentle vibration. 

The powder is sieved antistatically and stored in an internal tank for further use.

2nd phase: Dry cleaning & de-powdering

Mechanical cleaning without external media

Unpacked workpieces are mechanically cleaned in dry condition, using vibration and air flow. 

As far as possible, the workpieces are freed from powder, to allow a registration of workpiece contours and characteristics. 

Workpieces and powder are not treated with media, and therefore remain free from contamination.
