From Rolls-Royce Aeroengines to Desktop 3D Printing: An Duong's Bet
3D PrintingAn Duong spent years as Innovation Manager at Rolls-Royce, focused on 3D printed aeroengines. He left to found Morethan3D, a company producing desktop models using material extrusion — the same additive manufacturing process that runs on consumer printers in homes and makerspaces worldwide.
The career arc is the story: aerospace-grade process knowledge flowing downmarket into the consumer 3D printing space.
The Knowledge Transfer
Industrial additive manufacturing at a company like Rolls-Royce involves a level of process rigor that the desktop 3D printing world has historically operated without. Aerospace AM requires validated material properties, controlled environments, documented process parameters, and repeatability standards designed for parts that need to not fail at altitude. The engineering knowledge accumulated in that environment — how materials behave under deposition, what produces dimensional accuracy, how to think about support structures and thermal management — does not disappear when the printer gets smaller.
What Duong is doing at Morethan3D is applying that industrial process thinking to desktop-scale production. The specific output is models produced via material extrusion, distributed through commercial channels. The differentiation is in how the manufacturing process is understood and controlled behind the scenes, even when the end product looks like consumer 3D printing.
Why This Direction Makes Sense Now
The desktop 3D printing market has reached a maturity inflection. Machines from Bambu Lab and others have solved the reliability problem for mainstream consumers — printers that work consistently, calibrate automatically, and produce acceptable results without deep expertise. What the market has not yet fully solved is quality consistency at scale and the kind of design-for-manufacturing discipline that industrial environments take for granted.
Practitioners with industrial AM backgrounds entering the consumer and small-business market bring a different frame: not “how do I get this printer to work” but “how do I design and produce parts with predictable properties.” That distinction matters for any application beyond decorative models — functional prototypes, replacement components, small-batch production runs, engineering-grade assemblies. The 3DPOD episode with Duong covers the business viability of this approach and how Morethan3D distributes its work — a question that matters as much as the technical side for anyone evaluating a similar path from industrial to independent manufacturing.
The So What
The flow of industrial AM expertise into the desktop market is a structural trend, not a one-person story. As the machines commoditize and manufacturing knowledge becomes the differentiator, founders with aerospace, automotive, and medical device AM backgrounds will have a meaningful advantage over those who learned the technology in a consumer context. The hobbyist-to-professional pipeline is well-established in 3D printing; the industrial-to-independent path is newer and arguably carries more process depth. An Duong’s move from Rolls-Royce to Morethan3D is an early data point in what may become a recognizable career pattern in additive manufacturing.
