I've got a reprap 3d printer, but been having problems with extruding lately, and after spending hours cutting plasticard by hand, I looked at the possibility of mounting a flex shaft attached to a dremel on the printhead.
In theory you could relatively easily cut plasticard parts from a template.

Has anyone tried anything like this, can you cut plasticard sheets this way or do they melt.

In my experience a dremel (using cutting wheels) will melt as much as it cuts on plasticard even on the lowest setting (3000rpm on mine). It's okay for rough cutting but no good for fine cuts.

Thats what i was worried about. What about the tiny milling bits, i read they cut through acrylic without melting it.

I have got a high power laser diode, but its infra red and Im too worried for my eyesight. That and i'd prefer too be able to cut templates from the heavier guage plasticard

It isn't the bit that's causing the plastic to melt. It's the speed of the drill and subsequent friction that results in melted plastic.
