About us

Who we are

Two people with over 20 years of combined 3D printing experience who decided to stop doing it separately.

K

Kris Kraanen

Co-founder · 3D Designer · Mechanical Engineer

Started printing in his bedroom and never really stopped. Kris handles the design and engineering side of things, with hands-on experience across both hobby and industrial machines.

I

Igor Mars

Co-founder · 3D Designer · Mechanical Engineer

A mechanical engineer by trade and self-taught printer by habit. Igor works on everything from precision mechanical parts to larger production runs, and has been doing it long enough to know where most prints go wrong.

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 came out of the decision to combine what we each had. Machines, software knowledge, and a practical engineering approach. We can handle a quick prototype just as well as a precision mechanical part.

Both of us work as 3D designers and mechanical engineers in our day jobs. We know our way around 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.
