The present application relates to a printing plate for a three-dimensional printer and a three-dimensional printer. The printing plate comprises: a base plate, used for providing a bearing basis; and a polyurethane coating or polyester coating, arranged on the surface of the base plate and serving as a covering layer. During printing, the covering layer is in contact with a material and exhibits very strong adhesive force for the printing material, thereby avoiding the problems of warping and falling off of members undergoing printing. The printing plate with the polyurethane coating or the polyester coating as a surface layer material can still hold strong adhesive force to printing materials without damages to the surface even after multiple times of repeated printing.
