A translation stage (TS) is a component typically used to vary the position of an object along a single axis. The resolution of the moving platform is determined by the drive screw mechanism used to move the platform.
The translation stage is composed of the two pieces shown in the figures (TranslatioinStage_up and TranslationStage_bottom). Unlike a traditional system, the stage printed has two rods fixed to the moving section and the walls of the main platform act as bearings. With this scheme, it was possible to obtain a very stable and robust linear motion along the axis of the rods. The drive screw mechanism is built using a single nut that is embedded in one wall of the main platform. An M4 screw with a rounded nut at one end is used to set the position of the moving section over a range of 1.0 cm. For additional information go to http://arxiv.org/pdf/1606.09563.pdf
