Multifunctional modularized parallel 3D (Three-dimensional) printer

The utility model discloses a multifunctional modularized parallel 3D printer. The printer comprises a frame, a workbench, a printing head, a drive device and independent function modules, wherein a clamping block is installed on the top end of each function module; a first circular hole and a second circular hole communicated with each other are formed in the printing head; the pore diameter of the first circular hole is greater than that of the second circular hole, and the first circular hole and the second circular hole encircle a convex propping ring; a blocking and positioning bulge extends from the hole wall of the first circular hole; an annular compacting block is further installed on the top end of the printing head; a clamping area is formed between the annular compacting block and the convex propping ring; when the bottom end of each function module penetrates through the first circular hole and the second circular hole along the frame from top to bottom and the clamping block is propped against the convex propping ring, the clamping block is rotated to screw into the clamping area and is propped against the blocking and positioning bulge, and the annular compacting block and the convex propping ring commonly clamp the clamping block. The function modules of the multifunctional modularized parallel 3D printer is convenient and quick to replace, so that the multifunctional modularized parallel 3D printer has wide application scope.
