GTK-Prototype UG was founded in 2014 by Tobias Günther and initially dealt with rapid prototyping machines.

Over the years, CNC milling and turning as well as assembly and development work were added due to customer requirements.

GTK-Prototype develops and designs on behalf of customers as well as internally using the most modern CAD systems such as Solid Works, Autodesk Inventor, Fusion 360 and others and inserts them into a comprehensive CAM system.
Through the production of prototypes in medical technology, mechanical engineering and the automotive sector, GTK-Prototype was able to acquire extensive experience in manufacturing.

In 2018, the production option laser cutting was added.

GTK-Prototype is currently based in Neuhausen near Tuttlingen and will move to the newly built company location in Radolfzell in the course of 2022.

We produce elastomer parts up to a specificaion.
