20 years ago, I converted a 3-axis IC fab handler to drive
a dremel tool.
When I first learned about this, I considered replacing the
dremel with a plastic extruder. Seemed pretty straightforward.
Then I looked at the cost of the plastic extrusion filament
and dropped the whole project.

3D printing excels when you need the ability to make internal
features that can't be machined.
