The particular visitor for this third episode of the 3dpbm Pulse Podcast 2022 is James DeMuth, CEO of Seurat Applied sciences, one of the crucial thrilling new firms to emerge, concentrating on steel additive mass manufacturing, with its distinctive Space Printing course of.
DeMuth holds a Grasp’s diploma in Mechanical Engineering from Stanford College with a deal with vitality methods and high-temperature gasoline dynamics and a Bachelor’s diploma in Mechanical Engineering from Santa Clara College. He has co-authored 83 patents and 13 educational publications within the fields of additive manufacturing and energy technology.
Previous to founding Seurat, James DeMuth was at Lawrence Livermore Nationwide Laboratory the place he labored on the Laser Inertial Fusion Power undertaking. Engaged on one of the crucial superior machines ever created by people, he co-invented and developed the core of Seurat’s breakthrough Additive Manufacturing know-how, Space Printing.
Seurat Applied sciences just lately closed a $21M Collection B extension with investments Xerox Ventures and SIP International Companions, bringing complete funding for the corporate to $79M. What makes Seurat’s imaginative and prescient for massively scaling steel AM much more credible is that James’s background focuses on find out how to effectively deal with and exactly direct enormous quantities of vitality.
On this nice episode, we communicate with James to know extra concerning the firm’s distinctive proposition for extremely scalable steel AM through Space Printing know-how and the way this might result in extra sustainable mass manufacturing of steel elements.
“We now have a prototype machine prepared and we are able to print with materials high quality exceeding ASTM requirements,” De Muth advised 3dpbm, “and with which might be within the strategy of participating with giant OEMs to start to qualify their elements and their supplies to map out how we scale into collection manufacturing at value factors that compete with casting”. Seurat has almost 130 patents, granted and pending and giants like Siemens Power, Volkswagen, Xerox and Porsche which might be both or instantly invested in its Space Printing know-how.
One method to perceive the distinctive proposition supplied by Seurat is to check its Space Printing know-how in a approach that’s just like the transition in polymer AM from single-point laser SLA to high-speed processes corresponding to planar, steady DLP. Solely, in steel, this requires the power to deal with a a lot bigger quantity of vitality (to make use of a euphemism). “The patterning units that it’s good to use want to resist extra energy than the solar,” explains De Muth whose background is on the NIF (the Nationwide Ignition Facility) at Lawrence Livermore Nationwide Labs, one of the crucial superior buildings for the ignition of economic nuclear fusion know-how.
In polymers, you should use a micromirror however these methods can solely deal with small portions of vitality. Seurat developed a sample that would survive an enormous quantity of vitality and that’s what the NIF had been engaged on to pay attention the large laser energy wanted to start out the fusion response. “That is the enabling know-how behind Space Printing,” De Muth explains.
Seurat has already secured seven letters of intent to affix its commercialization program from the world’s largest automotive, aerospace, vitality, client electronics, and industrial firms, and expects to launch its first business packages this 12 months. The extra funding will likely be used in direction of constructing Seurat’s production-grade system which is focused to supply elements at $300/kilogram — akin to elements produced by machining. By 2025, Seurat anticipates decreasing manufacturing price to $150/kilogram, which is akin to castings. As Seurat grows, its tech will make the $1 trillion steel manufacturing market totally accessible to additive manufacturing.
