IMP seminar: Lithography metal manufacturing: The next generation of metal 3D printing

Abstract:

Imagine an additive manufacturing (AM) technology capable of 3D printing any design in any metal directly to a net shape: no support removal, no platform detachment, no CNC machining, but a “print on shelf” path bypassing the costly and time consuming workshop postprocessing. This has recently become feasible with lithography metal manufacturing (LMM), a vat photopolymerization technology that uses digital light processing on metal-filled resin to 3D print “green” parts for further debinding and sintering in a furnace. In the past few years, major AM players, such as Lithoz, Admatec, and Autodesk have spun off startup companies producing LMM printers whose accuracy and preciseness intriguing even Swiss watchmakers. Collaborating with one of such startups, we successfully produced steel parts with the accuracy, roughness, and design complexity unachievable for powder bed systems, including assemblies of parts enclosed inside other parts, multiscale metamaterials, intricate chemical reactors, micro-heat sinks, and bioimplants on a decimeter scale all within a petite 10m² lab space used for the full production cycle from feedstock synthesis to the net shape parts.

Drawing up on our results and success of emerging 3D printing service providers employing LMM, such as MetShape GmbH, I believe that LAM can empower small businesses in competition with large manufacturers by ruling out the need for costly infrastructure further democratizing the manufacturing sector.
