The Aluminum Heatbed MK3 have features similar to MK2 and you can also operate this board with 12V and 24V two voltage, more practical.

Heatbed with 3.2mm Aluminum Core. Print directly on the heatbed, no need for glass plate. It’s a much lighter solution than PCB heatbed + glass, which makes it better for faster prints. due to the aluminum substrate material is expensive, the cost of production is often ordinary glass fiber board is expensive, so the MK3 price is more expensive.

Please note the Aluminum Heatbed can have some marks or minor scratches, but it will only be of cosmetic character and will not affect the use adversely.


(1)Dual power supply. Operate at 12V or 24V. You can use thinner wires when operating at 24V.

(2)A central mounting hole on the front side to allow for three point mounting. This is much easier for bed leveling in comparison to 4 point mounting. First level the side with two holes and fix in place, then level the side with one hole.

(3)Large solder pads for multiple wires (ribbon cable) or a SMD pinhead connector can be mounted.

(4)Pads for SMD thermistor 1206.

(5)With 15V on the 12V terminals will maintain approx. 115 degree Celsius without regulation.

(6)Running 24V on the 12V terminals will heat up the heatbed to 100 degree in only 2 minutes

(7)Your printer controller will regulate the power to the heatbed in order to get your preset temperature.
