What is a heated bed?

A bed is the heated base of a 3D printer on which the build plate sits. Maintains stable temperature during printing and prevents warping.

Bed's role

A hot bed keeps the bottom of the print warm so it doesn't contract - warping prevention. Typical temperatures: PLA 60 °C, PETG 80 °C, ABS/ASA 100-110 °C.

Types

  • Aluminum plate - standard, good heat conduction
  • Magnetic plate - easily swappable plate
  • Silicone heater - more even temperature
