Product description
Silicone heater mat including thermistor and sticker to heat up larger bed plates. 1000W guarantees you a quick heating to the desired temperature
The thermistor is a normal 100K version that will work with option 1 in your firmware. Use a solid state relay to control the heated bed from your electronics and optionally a fuse to protect against shorting. Review the following example setup for more information. Connect the thermistor wiring to your electronics board's heated bed thermistor header. The solid state relay low voltage side should be connected to the board's heated bed output, mind the polarization. The high voltage side should be connected to the one of the leads of the silicone mat, the other side to one of the 240V leads. Finally connect the other lead of the mat to the other lead of the 240V input. You can use the C14CHSMNTSW to protect the circuit and have a convenient way to turn off the heater.
Warning: Working with 240V can be dangerous, always take adequate precautions. Don't work with power on.

Heating Resin Printers During Winter
This 4D Filtration resource is user-supported by donations, affiliate links, and/or ads.
Last Updated: April 10th, 2022
The following simulations are intended to provide a comparison between heating setups for resin 3D printers under a variety of temperatures.
The recommended method of heating resin printers is by using a 250-500 W ceramic heater that is temperature-controlled. This is the most reliable method since you can set your desired resin temperature. A 250 W heater should be good for temperatures no colder than -5°C, provided that your printer is enclosed. A 500 W heater is suitable for temperatures no colder than approximately -35°C.
The ideal situation for resin printing during the winter would be to have the printer in a garage, enclosed, heated, and ready to be vented when printing has concluded. Printing can be done indoors in a separate and sealed room, but you will have to rely on larger 1,500 W heaters due to the continuous ventilation required.

- Recommended: Enclosure, Ceramic Heater Temperature Controlled
- Example Setup: Two Printers + Grow Tent + Controller + Heater
Assumptions
- Small resin printer with a rated power of 45 W distributed across the base for simplification, cycling on for 1.
5 s (exposure time) and off for 17 s (1 mm/s lift and retract over 8 mm + 1 s light-off delay). - The printer cover is acrylic, the grow tent enclosure is oxford fabric, the vat and base are aluminum, and the resin has a thermal conductivity of 0.2 W/(m·K).
- There is approximately 310 grams (≈270 ml) of resin in the vat.
- No forced convection, wind, or drafts across the printer or enclosure.
- Target temperature of 30°C on the heater + controller setups.
No Enclosure or Heat Source
20°C (68°F) Ambient
When it is warm outside the main concern with resin printing is ventilation. During winter we have to make sure the resin stays at an adequate temperature as well (usually 20-25°C for budget resin and 25°C+ for engineering resin).
One balanced option is to have the printer in a garage while not venting till after printing has finished; this keeps fumes outside the residence and provides the opportunity for efficient heating. A printer in the residence can be heated, but heating the air that is instantly vented is not efficient.
No Enclosure & Small Heating Pad
20°C (68°F) Ambient
Adding a small heating pad is a safe and cheap method to raise the temperature of the resin during printing. Raising the temperature in a warmer environment can still be useful for engineering resins and reducing the exposure time on budget resin.
10°C (50°F) Ambient
When temperatures begin to drop, even the 6.5 W heating pad will be able to adequately support budget resin.
0°C (32°F) Ambient
The small heating pad becomes insufficient near-freezing temperatures. For a cold garage, an enclosure and a higher wattage heat source will be needed.
Grow Tent Enclosure & Small Heating Pad
20°C (68°F) Ambient
A grow tent enclosure provides only a minimal increase in the resin temperature during the warmer times of the year. However, it will aid in proper ventilation.
10°C (50°F) Ambient
When temperatures begin to drop, the added insulation of the enclosure becomes apparent.
There is a ≈1°C increase in the resin.
0°C (32°F) Ambient
At freezing temperatures, the enclosure will bump the resin temperature up by ≈2°C, but the ≈17°C resin is still below the recommended levels. The resin can print at this temperature but the exposure times and risk of failure will be higher.

Grow Tent Enclosure & Large Heating Pad
0°C (32°F) Ambient
Swapping the small 6.5 W heat pad for a larger 18 W variant will raise budget resin into its recommended range.
This heating pad can be attached to the interior or exterior of the acrylic cover, with the former being more efficient. You can use various attachment methods such as kapton tape, nylon string, or zip ties so long as the pad is not punctured.

Grow Tent Enclosure & Heater Thermal Runaway
0°C (32°F) Ambient
Adding more wattage will heat up the enclosure and resin faster but you have to be careful. Here you can see where a 250 W ceramic heater pointed at the printer will heat the resin towards 60°C. Beyond ruining the resin, this can damage electronics, warp plastic components, waste electricity, and start a fire.
Grow Tent Enclosure & Temperature Controlled Heater
0°C (32°F) Ambient
An efficient manner in which to manage the 250 W heat source is by using an inline controller or by purchasing a specialized unit.
You will be able to place the controller within the enclosure and set your desired temperature.
In this example, the heater outlet is parallel to the printer and the controller is on the far side behind the printer. Placing the controller's sensor probe too close to the heater's outlet will result in a lower resin temperature and placing it far away will heat the resin above your set temperature.
-20°C (-4°F) Ambient
The lower winter temperatures will lower the variance in the resin temperature. In this and the prior example, the target for the controller was 30°C. The prior example allowed the resin to rise ≈5°C above while this one is ≈1°C above.
The temperature-controlled heater will provide the best results to keep the resin at your desired target, but this method is more expensive to employ and uses more energy than the heating pads. Make sure that the controller you choose is rated for the power draw of the heater.

Lower wattage heaters outside the printer work fine for temperatures above freezing but they do not have enough heat output for anything below this.
Higher wattage heaters (500-1,500 W) will work below freezing but you must be careful so as not to overheat the printer or start a fire.
The incubator heater creates a heated chamber for the resin 3D printer. This type of heater is certainly efficient, but it can only heat one printer and is not plug and play.
Lower outdoor temperatures, wind drafts, and cracks in the grow tent will decrease both the efficiency with the heater and the maximum temperature it will be able to reach.
Resin Heating Setup Examples
Two Printers + Grow Tent + Controller + Heater
This particular example utilizes an open-air ventilation setup in a separate and sealed indoor room. The grow tent keeps the heat in and allows printing without the printer covers. A wide grow tent, such as the one pictured, has plenty of room for multiple printers or a wash and cure machine.
The heat source is one of the small Lasko heaters with an Inkbird controller - you can see the sensor probe dangling from the top of the tent.
For this setup, the controller is set to kick on when the temperature drops below 28°C. It will then run until it surpasses 32°C, where it will turn off and wait until it drops again. This keeps the entire grow tent near 30°C while reducing the wear on the controller.
This is the internal temperature of the grow tent setup above with an ambient temperature of ≈4°C. This test was conducted without the additional heat output of a resin printer and with minimal to moderate convection (drafts) on the outside of the grow tent.
This test demonstrates that a 200 W heater will max out at ≈26°C under ≈4°C ambient. However, it reaches 20°C+ within 10 minutes of starting up.
We will be conducting additional tests in the near future.
