NOVELTY - The application claims a printing base plate for 3 D printing and a 3 D printer, the printing base plate for the printing of the 3 D comprises: a supporting plate, a printing plate, a heat conducting plate, a heating layer and an insulating plate; wherein the insulating plate is set on the supporting plate, the heating layer is set on the insulating plate, the heat conducting plate is set on the insulating plate, the printing plate is set on the heat conducting plate; the heating layer is set to graphene a heat generating layer. The application reaches the heating part of the graphene D printing bottom plate, replacing the traditional silica gel heating plate, using graphene heating efficiency is higher, so as to reduce the printing bottom plate heating to the use temperature needed time, improving the printing efficiency of the technical effect, so as to solve the problem that the printing bottom plate in the related technology is heated to the use temperature for a long time, causing the problem of low printing efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a D printer.
