官方相對於MK2a、MK2b，MK3的最大優勢是鋁基板成品。
1。MK2a MK2b需要在加熱板上覆蓋一個高溫玻璃做載台。而MK3加熱板即使加熱板又是載台。可以節省加熱玻璃的費用了。
2。升溫比MK2系列快很多。
3。由於加熱台和鋁基板合而為一，升溫均衡度更好。

發貨清單：
1.MK3 鋁基板熱床 1個。
2.12.9級 M3 固定螺絲4個。 （出貨已經幫客戶安裝在熱床上）
實物實拍：
MK3 ALU-Heatbed Dual Power TheAlu-Heatbed MK3have features similar to MK2 and you can also operate this board with 12V or 24V.
- 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.
- Dual power supply. Operate at 12V or 24V. Your can use thinner wires when operating at 24V.
- 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.
- large solder pads for multiple wires (ribbon cable) or a SMD pinhead connector can be mounted.
- Pads for SMD thermistor 1206
Dimensions 214mm x 214mm
1 layer 35μm (1oz base) copper
Resistance between 1.0 and 1.2 ohm
Heatup time to 100 degrees Celsius less than 10min for both 12V and 24V
對於不熟悉3D打印機的客戶，我們特意做了以下幾幅圖片，讓客戶參考。
安裝一，鋁板加熱面，自行帖上高溫膠帶。（高溫膠帶在本店另外購買）
安裝二，加熱板這面，焊接上2個LED燈，和一個1K電阻。2個LED燈方向錯開，正常工作只亮一個LED燈。
安裝三，焊接上電源線。國內目前絕大部分都是12V的機器，就參考下面的焊接方法。
安裝四，安裝NTC熱敏電阻。這裡NTC電阻用導線加長然後在安裝。
