BMF CEO: The 3D Printing Industry Has Lost Sight of Its Own Magic

Boston Micro Fabrication CEO John Kawola has a message for the additive manufacturing sector after 27 years in the industry: stop taking the fundamentals for granted. In a candid interview on the 33DPQ podcast, recorded at RAPID + TCT, Kawola argued that while the technology has matured significantly, the industry is still struggling with the transition from prototyping to production manufacturing. The Numbers Don't Lie

Kawola's assessment starts with the positives, and they are substantial. Customer spending on machines, materials, and services has grown tenfold over the past decade. Machine capabilities, material portfolios, and software tools have improved dramatically while costs have dropped. These are not marginal gains, they represent a fundamentally different value proposition than what existed five to ten years ago.

But the challenges are equally real. The shift from using 3D printing as a communication tool, what Kawola calls "still very much the killer app," to manufacturing production remains technically difficult. Getting part properties to match application requirements while making the economics work is what he describes as "a steep hill." The Manufacturing Reality

Kawola points to dental, aerospace, and orthopedic implants as sectors where additive manufacturing has proven itself. These are not niche applications, they represent billions in annual production. Yet in other industries, the transition remains incomplete. "A lot of people have sort of tried to run up that hill and have fallen back down because it's hard," he noted. He rejects the idea that these represent industry missteps. It is simply a big challenge that takes time to solve.

The investment wave that began around a decade ago brought both benefits and problems. Formlabs emerged as a genuine success story. Technologies improved across the board. But the market became crowded with competing vendors driving down prices and compressing margins. Kawola suggests some funded companies were pursuing technologies that were never going to work commercially, leaving the industry to deal with that hangover. What Engineers Still Get Wrong

The workflow problem persists. Kawola estimates that nine times out of ten, parts are designed for traditional manufacturing, molding, machining, or stamping, and only then considered for 3D printing. Sometimes this works. Often it does not.

The deeper issue is missed opportunity. Designing specifically for additive manufacturing removes many of the constraints imposed by traditional processes. Parts can be stronger, lighter, and better performing when engineers start with 3D printing in mind rather than treating it as an afterthought. Kawola is clear that additive manufacturing still has constraints, but they are fewer and different from conventional methods.

This design-for-additive mindset remains underutilized across much of the engineering world. After three decades of 3D printing availability, the sector is still, in Kawola's words, "stuck in the m..." The sentence trails off in the transcript, but the point is made. The magic of rapid prototyping has become routine. The harder work of rethinking design philosophy for manufacturing remains unfinished.

M4S TAKE

My take: capacity expansions signal confidence, but the real question is whether demand justifies the spend. I watch for follow-up announcements about utilization rates or new contracts. Without those, this is just capital allocation.
