From Prototype Wonder to Industrial Workhorse
The 3D printing industry history can be seen as a shift from an experimental communication tool for engineers into a growing platform for digital manufacturing that still struggles to balance its original sense of wonder with the hard demands of production scale, material performance, and economic viability. For John Kawola, CEO of Boston Micro Fabrication (BMF), that journey spans 27 years of watching additive manufacturing evolution from the inside. He notes that customer spending on machines, materials, and services has not fallen; in fact, he says it is “clearly 10 times bigger than it was 10 years ago.” At the same time, today’s machines, materials, and software are far better and more affordable than a decade ago. Yet alongside this technical progress, Kawola argues, something important has faded: an appreciation for the original “magic” that made 3D printing innovation so compelling for engineers in the first place.
What Went Wrong? Growing Pains, Not a Broken Technology
Asked what is wrong with 3D printing, Kawola rejects the idea of a broken industry and instead describes hard growing pains. The first is the leap from prototyping to manufacturing. As a communication tool, 3D printing lets teams hold a part within hours, compare concepts, and align quickly; he still calls that capability “magic,” even if many now treat it as routine. Turning that same process into a reliable production method is far harder. Parts must achieve demanding properties and economics must match or beat molding, machining, or stamping. That has worked in focused areas such as dental, aerospace, and orthopedic implants, but progress elsewhere is uneven as companies “run up that hill” and slide back. A second challenge came from a wave of investment that crowded the market with new vendors, driving down prices and leaving a hangover of ideas that were never likely to succeed.
Forgotten Magic: Design Freedom as the Real Breakthrough
For Kawola, one piece of forgotten magic lies in how engineers think about design. Many projects still begin with a part created for traditional processes, and only later does someone ask whether it can be 3D printed. Sometimes that works, but often it wastes the chance to exploit additive geometry, internal features, and consolidation. Designing from the start for additive manufacturing removes many of the limits of molds or cutting tools and can yield lighter, stronger, or better-looking products. Kawola believes engineering culture is still “stuck in the mud” here, treating 3D printing as an afterthought instead of a core design assumption. He points to the coming mix of generative design and AI, where an engineer specifies constraints—size, load, target weight—and software proposes optimized forms that are then checked for printability. In his view, the future magic is software-driven, but it starts with remembering to design for additive first.
An Industry Veteran’s Roadmap: Manufacturing, Software, and Medicine
Looking ahead, Kawola’s industry veteran perspective blends realism with optimism. He expects additive manufacturing evolution to continue in focused verticals where the technical and economic fit already makes sense, while other sectors will progress more slowly. Software will play a larger role, with AI-supported workflows advising whether a bracket can be made on an FDM machine and how to change it if not. The most meaningful 3D printing innovation, in his view, is happening in healthcare. Kawola points to implants such as titanium hips—he has one himself—and to BMF’s own work on tiny components and delivery tools for the eye, ear, and neurological surgery. In many of these cases, he notes, the procedures “would not have been able to do this other ways.” For him, reclaiming the magic means keeping that practical impact in sight while remembering how extraordinary it still is to hold a new idea in your hand by the end of the day.
