3D Printer Enclosure Heater – FDM & Resin

This project is a compact heating module designed for active temperature control of 3D printer enclosures, compatible with both FDM and resin printers.

It is ideal for improving:

bed adhesion

warping reduction

thermal stability during long prints

Especially suitable for engineering materials and closed or DIY enclosures.

The heater housing is designed for FDM printing in ASA, chosen for its high heat resistance, dimensional stability, and long-term durability.
