5 axis laser-assisted selective metallization of large 3D parts

We have been developing a 5 axis manufacturing cell containing an embedded 100W fibre laser. As part of this we have been investigating various routes for utilising the laser to achieve selective metallization, with the ultimate goal being rapid, end-to-end metallization of complex shapes on 3D surfaces.
In this talk I will cover some of the key mechanisms we have been utilising. The first involves using a maskant, which serves as a barrier layer for subsequent electroless copper deposition. The laser is used to selectively ablate the mask. In the second technique a silver paste is deposited onto the substrate, ablated then sintered. Finally, I will discuss our latest developments with other emerging techniques
