Use this tag for questions about the Heated Build Platform or Plate (HBP) for 3D printers.

A Heated Build Platform (or Plate) is an additional piece of hardware that provides an additional heating element in the build platform. It is a required piece of hardware for plastic filaments that shrink considerably. As the extruded plastic cools, it shrinks, and when unevenly cooled down because of the geometry of the print, it can result in a warped part lifting from the platform. At elevated temperature, shrinkage is less and more evenly when the bed temperature is close to the glass temperature of the plastic resulting in higher quality prints.
