Frame body device specially used for clay sculpture 3D printing

The invention discloses a frame body device specially used for clay sculpture 3D printing. The device comprises an operation bench. The operation bench is symmetrically welded with two support columns. The lower ends of the two support columns are symmetrically welded with first-grade support plates. The first-grade support plates are provided with lifting combination devices. Cross rods fixedly sleeve the lifting combination devices. In the invention, through bevel gear transmission, the cross rods and a print head device are driven to move up and down; an electric push rod is used to make the print head device move along a left-right direction on the cross rods; engaged gears are used to drive the mutual transmission of a roller screw rod and a roller nut so as to realize the smooth movement of a mobile platform on the operation bench along a forward and backward direction; through using abutting slide between a slide rail and a chute, the stability of the whole operation process ofa printing device is furt
