Process development for additive multi-material fabrication

• extension of the known laser-beam-melting-process with a paste-extrusion-process
• form a cavity with laser beam melting, from which the powder is being removed
• bring the paste in this cavity
• thermally debind the paste and sinter or melt the powder content of the paste
• repeat this process until the final part is finished
• avoid intermixing and contamination of starting material: powder and paste
• it is possible to insert more than one more material

 

Possible Applications:

• tooling: insert highly thermally conductive components (copper-inserts) in filigree tool domains, which cannot be provided with a cooling channel
• integration of functions: e.g. integration of conducting paths incl. isolation, insert directly manufactured sensors/actuators, magnetic materials, etc.
