How to achieve a perfect installation of a Keenovo heater pad to your 3D printer's build plate

One of our most frequently asked questions is :" what is the suggested/best setup/installation method of my Keenovo heater pad to my build plate?" Hope the information below helps if you are wondering about the same.

First, as most Keenovo 3D printer heater pads come with 3M PSA, we suggest following your "User's Manual--Keenovo Flexible Heater" for a general guide on installation with factory applied adhesive backing.

Then, a proven great setup goes like this "sandwich clamp"(from bottom to top):

Aluminum Plate/Thermal Insulation/Keenovo Heater Pad(adhered to)/Aluminum Plate/Borosilicate Glass

Please kindly note:

    • The suggested thermal insulation material is silicone sponge sheet of 5mm thick, however, we were told that customers also get good results using cork sheet as the insulation.
    • Clamps/chips should be applied to the "sandwich" to have them tightly clamped. The heater pad handles even pressure very well. So, theorectially, the tighter the better, so far as its heating performance is concerned. There is no need to use extra glues between the other layers.
    • It's strongly suggested to make notches on the thermal insulation sheet,especially when it's hard such as a cork sheet, for the power wire bulge and the therimstor bulge so pressure is applied to heater pad surface evenly.
    • If your build plate moves while printing, please secure the cables to avoid wire breaking from frequent flexing or friction.
    • Last but not least, proper grounding of the aluminum plate with which the AC heater pad is in direct contact is strongly suggested.

This set up shall help improve the heater's heating efficiency and increase its serving life.
