Fabrication of a planetary drive in silica glass with already mounted gearwheels featuring a double-helical gearing.
The process for fabrication consists of two steps comparable to the making of a photo back in the analog times:
1. Material change by light exposure
2. Developing the structure (i.e. removal of the exposed material) by chemical wet etching
