Developing graphene - polymer composites for SLS printing applications

Important results from the project

The main goal of this project was to produce polymer - graphene composite powders for SLS printing. The overall expected outcome was to obtain electrically conductive parts with good structural integrity. This has been achieved using a coating method that has zero by-products and does not use any toxic chemicals . In addition, this feasibility study was conducted to evaluate whether polymer- graphene composite powders could be obtained using using a novel approach. This approach has resulted in spherical particles.

Expected long term effects

This feasibility study has generated very promising results for both partners. Graphmatech has great focus on Additive manufacturing in their business model and aims at launching such products. This study has generated promising results. From a sustainability prospective both methods prove feasible. There has been no use of harmful or toxic products and there is no waste in the processes developed as all by products have the possibility to be recycled back in the process. UU is interested in publication. The data of this study are unique and publishable to our knowledge.

Approach and implementation

The project went according to plan to its greater extend. Work package 1 deliverables have been accomplished 100%. Work package 2 was delivered by 50%. Further work is needed to mitigate the challenges with particle size. However, the successful development of spherical graphene- polymer particles was successful. These are promising results that we are willing to investigate further. Work package 3 was delivered 100% using an alternative approach. Geometrically correct, well sintered and electrically conductive parts were successfully printed.
