About us

Who we are

Two 3D printing enthusiasts with a combined experience of 20+ years, who finally decided to bundle their skills and build something together.

K

Kris Kraanen

Co-founder · 3D Designer · Mechanical Engineer

Started 3D printing in his bedroom and never stopped. With a technical background and years of hands-on experience across hobby-grade and industrial machines, Kris brings deep knowledge of both the creative and engineering side of additive manufacturing.

I

Igor Mars

Co-founder · 3D Designer · Mechanical Engineer

A self-taught engineer who has spent years pushing the boundaries of what desktop machines can produce. Igor combines his day-to-day work as a mechanical engineer with a passion for designing and printing parts that actually work in the real world.

We have both been building, printing and iterating in our home setups for years — through failed prints, material experiments and late-night calibration sessions. What started as a hobby became a serious skill set, and eventually a business.

KM Studio was born from the decision to stop doing it alone and start doing it together. We pooled our machines, our software knowledge and our engineering instincts to create a studio that can handle everything from a quick prototype to a precision mechanical component.

We are self-taught engineers with demonstrated experience in Onshape, Blender, Fusion 360 and SolidWorks, working with machines ranging from DIY hobby-grade printers to industrial large format systems. Both of us actively work as 3D designers and mechanical engineers in our day jobs — so when we take on your project, you get professionals who live and breathe this every day.
