This build plate is an original replacement part for the Saturn 3 Ultra 3D printer from Elegoo. The printed circuit board is made of an aluminum alloy, which prevents it from deforming, and has a laser-engraved surface, so that the first layer adheres well. In addition, it comes with a levelling system on 4 points, so that it only needs to be levelled once. Finally, this plate is easy to replace.
