Additive manufacturing (AM) or “3D-printing” is a manufacturing technology which allows the formation of complex geometries under computer control. Flowability of metal powder is among the challenges in metals AM industry. Graphmatech, a Swedish graphene materials technology scaleup company focuses on solving industrial challenges with graphene technology, have breaking news to share. Graphmatech scientists recently achieved remarkable improvement in the flowability of metal powders. This is another milestone in the success story of Graphmatech AB (founded 2017) that began with the patented technology and material Aros Graphene®. Strategic collaborations with Swedish, Swiss and German key industries, lead to that Graphmatech was appointed the “Nanotech company of the year in the Nordics” in 2018.
The latest story, on 3D printing enhancements, is best told by Dr. Mamoun Taher, the CEO, and co-founder of Graphmatech:
”Being a CEO of the fast-growing Graphmatech has never stopped me from being at the lab doing innovative and outside of the box experiments. One late afternoon, I went to the lab with an intention to investigate the influence of a graphene-based material on the magnetic properties of metal powders. Unexpected behavior of metal powder was observed after treatment with the graphene-based additive. The dreams about the observations woke me up very early the next morning and made me drive to Uppsala University to microscopically investigate the results from last night.
The results were immediately discussed with our collaborator at Uppsala University, Prof. Ulf Jansson, a Chair Professor, Inorganic Chemistry program leader and the leader for Additive Manufacturing Program at Uppsala University in Sweden.”
”When I saw the samples and results I immediately told Dr. Taher that this has the potential to solve a major challenge in metal powder industry and mainly for metal additive manufacturing. And this then turned out to be right! The newly found multifunctionality of the graphene-based additive allows the simultaneous addressing of different challenges in metal powder industry, and we are eager to continue our research” Says Prof. Ulf Jansson.
Further research and development have been carried out between Graphmatech and the group of Prof. Jansson to optimize and develop an eco-friendly, cost-efficient and scaleable process for treating metal powder with graphene-based materials for additive manufacturing and powder metallurgy.
Graphmatech was founded by material scientist Dr. Mamoun Taher and the serial entrepreneur Björn Lindh. The major investors of the company are ABB Technology Venture, InnoEnergy and the well-known business angel Jane Walerud.
