Mimaki Has Spent a Decade Trying to Make Full-Color 3D Printing Work. It Is Starting To

What Mimaki Actually Builds

Mimaki's 3D printing hardware sits in a category most desktop 3D printing enthusiasts will never encounter in person. The 3DUJ-553, the current flagship, has a 508 by 508 by 305 mm build volume and costs roughly $200,000. The 3DUJ-2207 is the scaled-down version: 203 by 203 by 76 mm, small enough to fit through a standard office door, priced at around $42,000 plus a mandatory $7,000 installation and training fee. These machines use UV-curable inkjet material jetting, the same general approach as PolyJet. Liquid photopolymer resin is jetted in layers as thin as 20 microns, cured by UV light as each layer goes down. CMYK plus white and clear inks are combined during printing, producing over 10 million possible colors directly from the file without any painting afterward.

That color capability is the selling point. Mimaki borrowed its colour science directly from decades of 2D commercial print experience. The company claims the colour gamut covers roughly 84 percent of the Fogra 39L standard and 90 percent of SWOP, benchmarks from the commercial print world that most consumer 3D printers do not even attempt to meet. For certain applications, that accuracy matters.

The Market Pivot Nobody Predicted

Mimaki entered the 3D printing market in 2017 with a grand vision: full-colour 3D printed signage. The dream, as described by Matthew Stark, Mimaki USA's 3D Segment Manager, was to produce photorealistic human figures and large mechanical signs on demand, the way 2D printers produce posters today. It did not work out that way.

The problem was weight and cost. A 20-kilogram object printed in fully cured ink is expensive. The economics of large decorative signage simply did not hold. What did hold was medical modelling. In medical applications, Stark put it plainly: there is almost no price for a model. Surgeons planning complex procedures will pay for a full-colour anatomical model that matches the patient's actual tissue coloration. The speed advantage over the old workflow of printing a part, shipping it to a factory for hand-painting, and waiting a month was transformative for hospitals willing to pay for it.

There is also a surprising consumer-goods angle. Funko, the company behind Pop figure collectibles, uses Mimaki's 3DUJ printers to produce prototype pieces printed in the exact same plastic color as the eventual injection-moulded production run. That lets Funko test paint jobs against a sample that behaves like the real manufactured product. Funko has taken these prototypes to toy trade shows without disclosing they were 3D printed, simply to preview upcoming releases without revealing production tooling.

Where AI Connects

Mimaki's value proposition becomes more interesting when you consider the AI 3D model generation tools entering the market. If an AI tool generates a full-colour 3D model with colour data embedded directly in the file, Mimaki's machines can print that colour data without any manual colour-separation step. That is exactly the pipeline VoxelMatters flagged as a plausible future direction for full-colour 3D printing. The 3DUJ-2207 does not need filament swaps, AMS management, or HueForge-style colour mapping. It jets the colour from the file and moves on.

This is a fundamentally different workflow from what most hobbyist and prosumer 3D printer owners experience. It is also a workflow that becomes more viable as AI-generated 3D models improve in fidelity and colour accuracy.

The Roland Question

Roland DG has been Mimaki's closest competitor in large-format print-and-cut and UV flatbed printing for decades. Anyone who has worked in signage, vehicle wraps, or promotional print production has likely used hardware from both companies. So the natural question is whether Roland will follow Mimaki into full-colour 3D printing.

Roland has not announced a 3D printer. But it already has the underlying technology in place. Roland's DGSHAPE subsidiary produces a dedicated dental 3D printer, and the company's May 2026 industrial UV announcement included a new VersaObject IO-300 flatbed UV printer and cylindrical UV printing series. The ink chemistry and UV curing hardware Roland is actively developing for flat and cylindrical decoration is the same technology stack that would be needed for a desktop full-colour 3D printer. Whether Roland's management sees the market as ready is the open question.

If Mimaki's decade of trial and error has taught the wider industry anything, it is that full-colour 3D printing found its market in places nobody predicted: not signage, but medical models and precision prototyping. A company with Roland's chemistry, manufacturing scale, and global distribution network could move into that space faster than most observers expect, if it decided the timing was right.

Why This Matters for the Wider Industry

Full-colour 3D printing has spent most of its existence as a curiosity, a niche technology for concept artists and industrial designers willing to pay industrial prices for industrial machines. Mimaki's experience suggests the real demand is narrower than the marketing promised but deeper than the hobbyist market assumed. Medical modelling, rapid prototyping where colour accuracy cuts weeks from the workflow, and collectibles prototyping are not mass-market applications. They are, however, real and growing.

The sub-$50,000 price tag on the 3DUJ-2207 is still well beyond what most prosumer 3D printer buyers will consider. But it is considerably lower than the entry point a few years ago, and as AI-generated full-colour 3D models improve, the justification for a machine that can print those models directly without post-processing gets stronger. Mimaki stayed the course when the original vision collapsed. That discipline is starting to show returns.
