Summary

This is a prototype of a non contact, low temp, heating coil that’s embedded in a cylinder. I made this by subtracting a “spring” helical shape from a cylinder and then subtracting a center rod from the cylinder.

It was possbile to push a thin wire into the channel without any effort although I could have used oil to lubricate the wire.

  • Created on a Form1 Clear 0.1mm resolution.
  • Object designed in truSpace CAD program.
  • Build time 30 minutes.

Instructions

  • This can be used as a low voltage, low temp heating element that does not contact the central channel.

  • The sprial was created by sweeping the surface of a 2mm rod with a 10 degree x tilt and a 20 degree y tilt. The resulting “spring” shaped object was then subtracted from a larger solid rod. The central channel was then subtracted from a smaller diamter than the inner diameter of the coil.
