I am currently building the microscope while doing the FabAcademy.
With some friends, we were thinking about a solution to produce fully 3D printable machines that make machines including high precision ones.
I find the design of the stage extremely interesting for that purpose.
The design that was built is the following. It is very nice because there is no z displacement but it is problematic because the range of motion is very small compared to its size :-5mm to +5 mm with the full device being 30 cm wide.
It is based on the thesis of Shoryar Awtar (2004)
The idea would be to fix a bed to the stage and put a drill on the z axis (or an extruder) to build small but precise parts at first with very limited sourced parts.
I would love your feedback and suggestions on that idea.
