This is a mechanical watch with tourbillon driven by a 3d-printed mainspring. The watch has a Swiss lever escapement. The mainspring inside the going barrel keeps the watch running for approximately 30-45 Minutes. Accuracy is roughly one Second deviation within one Minute (depending on print-settings).
The project demonstrates that the 3D-printing technology is developing. Compared with earlier generations of 3d-printers, the process works more reliable and more accurately. However it's still a very advanced project, because printing inaccuracies need to be trimmed manually with some watchmaker skills, or the watch won't tick.
The watch is designed with Autodesk Fusion 360, and printed with Ultimaker 2.

Many thanks to Nicholas Manousos for his great article in HODINKEE explaining the importance of my project from a watchmakers perspective. His first 3d-printed Tourbillon 1000% was also a source of inspiration for my work.
