With the dawn of https://3dprinting.stackexchange.com/, I thought we should (re-)evaluate if questions about 3D printing are on topic here on robotics.SE.
I guess if the question is mostly about robotics and 3D printing happens to be the application, like in these examples:
How do I calculate the inverse kinematics of a delta printer?
What PID settings will allow a smoother movement of this 3D printer axis?
are on topic here, while questions that are mostly about 3D printing and only happen to be related to robotics do not belong here:
- In what orientation should I slice this holder for a robot arm servo?
- How long will it take to print this robot arm?
