Heater for Elegoo Mars Printer

thingiverse

I built this custom heater for my Elegoo Mars printer to use resins that print best at 30 degrees C or higher without heating up the whole house. It's designed to sit between the printer base and cover, with a duct connected to the back that has a 60mm fan and heater core embedded in it. A pair of vents allow heated air to flow in and cooler air to circulate, keeping resin fumes from spreading around the room. The heater is controlled by an electronic thermostat unit and powered by a 200-watt power supply (150 watts would have been sufficient). I also designed a printed enclosure for the thermostat and power supply that's included in the project files. The thermostat is easy to program and comes with a sensor that you place inside the printer enclosure to maintain the set temperature. I printed everything on a large filament printer as all these parts are too big to print on a resin printer. However, if you want to slice it up into smaller parts and do it that way, go ahead! Not included is an ordinary power cord and plug to run off 120 volts house power (in the USA). If you're not comfortable with handling high voltage wiring, please don't attempt this project.
