3D printer

The utility model provides a 3D printer, including printer body, set up on printer body the cistern and with cistern complex pulling mechanism, the cistern rotationally sets up on printer body, 3D printer is still including drive cistern pivoted actuating mechanism. The utility model discloses a rotationally set up the cistern on printer body to the cooperation sets up drive cistern pivoted actuating mechanism, considers that 3D prints the in -process, considers that photosensitive resin curing's process can experience liquid (rare), liquid (thick), solid (soft), four stages of solid (managingto do sth. With difficulty), as photosensitive resin curing during to the state of solid (soft), make the ventilative layer separation of print and printing opacity through the rotatory constant angle degree of actuating mechanism drive cistern, so this moment since print curing molding can not cause " draging " phenomenon to because solidification is thorough yet, so the ventilative layer of printing opacity is more eas
