Process-integrated post-processing of high-precision additive manufactured

The proposed research project is in collaboration of a Montreal-based industrial partner. They are a solution provider in the high-precision metal additive manufacturing (AM) field, combining AM, nanotechnology and machine learning. They provide unique freedom of design and material choice for high-precision parts by their developed 3D printer combining Power Layering technology with laser sintering. However, most of the generated micro metal parts for their markets require post-processing steps. As additional process steps appear to be undesired, deploying post-processing could have an additional benefit of reducing the overall manufacturing time by balancing layer height and the polishing process to reduce the surface roughness of the generated metal micro-parts. Among other methods, electrochemical polishing (EP) seems a promising candidate for post-processing such parts. Nevertheless, EP is still unexplored in combination with this novel high-precision 3D printing method.

The proposed project aims to find a trade-off between layer thickness, printing speed and polishing. An optimum should be achieved to get smooth and flat surfaces to maintain high quality parts at reasonable fabrication time. Secondary, the project aims to acquire more knowledge of the printing technology and its interaction with post-processes.
