About Repetier

Since 2011 we are absolute 3D printing enthusiasts and develop several software solutions for 3D printers. Our first printer was a RepRap Mendel. At that time no useful software was available, so we started to program Repetier-Firmware and Repetier-Host to achieve the best possible printing results. Later Repetier-Server was added to optimize the possibilities and get more flexibility.

Repetier started as a hobby and quickly became a full-time job, but until now it’s still a hobby – just a full-time hobby. For this reason, we develop Repetier with passion and continue improving. From this inner drive our success results in the 3D printer community and we are proud to have contributed a piece to the 3D printer hype.
