Summary

Heating your SLA 3D Printer/Resin to about 30C (86°F) will give much more consistent results and many fewer failed prints. Some resins, such as Siraya Tenacious and Dragon Metal will not work at lower temperatures.

This heater case provides an easy way to attach the heater with Velcro and keeps the spacing within the printer fixed. The total system is a 12V 100W resistive heater with a small 12V power supply (15Amp) and a low-cost temperature controller.

The heater is wired through the temperature controller relay and the heater fan is wired directly to the power supply, so that it is on all of the time,

Modifications to PTC 12v Heater Case for EPAX X1 (Thing this remix is based upon):

1. Modified Heater case so that the "holding tabs" better match to the "slots" on the heater fan

2. Added Temperature Controller with acrylic case (Amazon): https://www.amazon.com/gp/product/B07WLTR1R4/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&th=1

3. Modified Temperature Controller Case by adding a "short side" with 8mm x 2mm neodymium magnets. Magnets are glued in with epoxy so they stick to the steel side of the 3D printer

Wiring the heater and temperature controller is simple. I wired the fan to be ON all of the time to help keep from having any hot spots. The temperature sensor is placed as far away from the heater as possible and near the resin vat. I decided not to drill a hole in the case for the wiring - most of the wires fit in the space between the base and the bottom of the cover when it is in the closed position.
