About
- OSE Reasons for using a nichrome 120V bed are scalability and lower cost for large beds.
- Reason for DIY nichrome beds is clear for larger beds, which would be rather expensive.
- Significant testing is needed for a safe method. Fiberglass coated wire, insulated bed, clamp-on as opposed to double sided tape is preferred for higher temperature printing. For small beds, we can make whatever size we need.

Coated Nichrome Wire
- Need 30 Ohms of wire, about 10' long
- See Nichrome Wire
Uncoated Nichrome Wire
- Need 30 Ohm resistance for the length of wire at 120V to get 480W, for P=IV, V=IR, I=V/R -> P=V^2/R = 120^2/30 according to Electrical Power Calculator.
