Abstract: Imagine an additive manufacturing (AM) technology capable of 3D printing any design in any metal directly to a net shape bypassing costly workshop post-processing. This once-distant goal has recently materialized with Lithography Metal Manufacturing (LMM), a vat photopolymerization approach that employs digital light projection to 3D print metal-filled resin into “green” structures, which are then debound and sintered in a furnace. Leading AM pioneers, such as Lithoz, Admatec, and Autodesk, have spun off startups producing LMM printers whose accuracy and preciseness intriguing even Swiss watchmakers. Through collaboration with one such startup, we successfully refined a now-industry-adopted LLM printer to fabricate steel components with a level of detailing, surface finish, and design complexity surpassing what powder bed systems can achieve. The entire end-to-end process, from feedstock preparation to finished parts, fit within a compact 10m² lab space, empowering small AM service providers in further decentralizing the production landscape.

Bio: Dr Ruslan Melentiev is an incoming Assistant Professor in Smart Manufacturing at the University of Nottingham’ Ningbo Campus, who was trained in manufacturing technologies at KAUST (postdoc), University College Dublin (PhD), Aircraft Industry (R&D Engineer), Turin Polytechnic (Scholar), and Odesa Polytechnic (MSc). He has received three Erasmus Mundus awards, Young Inventor award, and Science Foundation Ireland grant. He is the member of the International Academy of Engineering and Technology (AET), UK Metamaterials Network, and Saudi Arabian Society for Composite Materials. He has first-authored over 30 publications and 8 patents, commercialized with Saudi Basic Industries Corp, TOYOTA Motors, and several original equipment manufacturers in the US and India.
