Chamber Heater

Compact 800W heater for your 3D printer enclosure. Obviously print in high temp filament.

Strip down 2 of these for the heating elements, fans, and brackets:

I used a single one as is for a while, but can't maintain over 70C. 2 don't fit neatly so I made a new housing.

Will need an external temp controller, either a ITC-1000, or modified Marlin firmware with chamber heat control.

Since these are PTC self regulating heating elements, they don't really go over 180C at the hottest point. Running 30 hours so far at 85C chamber temp, and no issues with melting when printed in nylon. Will be going hotter eventually but I need to cool my stepper motors first.

Higher flow fans may keep the element temperature lower (and make the PTC flow more current), increasing average wattage and heat the chamber faster from cold.
