The working principle is as follows: firstly, the liquid material tank 7 with three primary colors is connected with the feeding pipes 9 through the matching of threads, so that three different colors of red, yellow and blue are respectively carried out inside three pipelines at the top of the four-way pipe feeding pipe 9, then the photosensitive resin liquid of the liquid material tank 7 is squeezed into the mixing barrel 10 through the electric squeezing cylinder 8, for example, when the three primary colors are required to be used for color mixing, the gear 38 is driven to rotate through rotating the handle 6 in a forward rotation manner, so that the rack 37 is driven to move towards the outer side of the feeding pipe 9, and as the first scale line 43 at the top of the rack 37 corresponds to the second scale line 44 at the top of the control plate 36 inside the control box 35, the control plate 36 is pulled to move towards the inside of the feeding pipes 9, so that the discharging proportion of each feeding pipe 9 is controlled, and the proportion of the three primary colors is ensured to be 1: 1, it is spacing to mutually support through slider 45 and spout 46 simultaneously, thereby prevent to pull out accuse flitch 36 from accuse magazine 35 inside completely, after the proportion calibration, through promoting stopper 41 on the pivot 39 to the print pen body 5 inside along spacing groove 40, thereby extend from locking piece 42 to from locking groove 34 inside and carry out the auto-lock, prevent that gear 38 from removing, influence the accuracy of proportion, when needing to assess the discharge amount accurately, for example when the photosensitive resin liquid that needs 10cm year, can control electric telescopic handle 3 through controller 4 and carry out work, thereby promote stripper plate 48 and remove to mixing barrel 10 top, move stripper plate 48 to the 10cm year position that scale 18 shows, thereby control the volume of material, when photosensitive resin liquid reaches 10cm year, promote accuse flitch 36 to accuse magazine 35 inside through the cooperation of gear 38 with rack 37 through reversal rotation handle 6, the three primary colors are prevented from continuously entering the interior of the mixing cylinder 10 through the rack 37, then the three primary colors extend to the interior of the self-locking groove 34 through the self-locking block 42 for self-locking, after the photosensitive resin liquid enters the interior of the mixing cylinder 10, the electric telescopic rod 3 is controlled to work through the controller 4, the extrusion plate 48 is extruded towards the top of the mixing cylinder 10, meanwhile, the control valve 47 is opened through the controller 4, the photosensitive resin liquid passes through the threaded pipe 21 to enter the interior of the through hole 22, before the photosensitive resin liquid enters the through hole 22, the rotating block 11 is rotated first, the convex ball 27 at the bottom of the mixing cylinder 10 moves along the interior of the spherical groove 28, so that the connecting hole 25 and the through hole 22 are accurately positioned through the mutual matching between the clamping block 30 and the built-in groove 31, the through hole 22 shielded by the 33 is aligned with the connecting hole 25, the single-head discharging or multi-head discharging can be freely adjusted, then, the feeding tube 2 is moved towards the inside of the through hole 22 to be tightly connected with the through hole 22 by manually pushing the print pen head 1, meanwhile, the fourth magnets 26 on the two sides of the feeding tube 2 slide along the inside of the sliding groove 24, so that a suction force is generated by the mutual matching between the fourth magnets 26 and the third magnets 23 to fix one end of the feeding tube 2 inside the through hole 22, then the photosensitive resin liquid is fed into the feeding tube 2 through the threaded tube 21 to flow into the inside of the print pen head 1 for 3d printing, during the process of entering the inside of the first print pen head 1, the second spiral stirring shaft 16 can be driven to rotate by the mutual matching between the second spiral stirring shaft 16 and the threaded groove on the top of the mixing cylinder 10, so as to stir and mix the photosensitive resin liquid, thereby driving the second spiral stirring shaft 16 to move towards the inside of the connecting groove 15, when the second spiral stirring shaft 16 and the top of the connecting groove 15 are contacted with each other, when the inner wall of the second spiral stirring shaft 16 is matched with the first spiral stirring shaft 20 to push the first spiral stirring shaft 20 to move towards the inside of the second spiral stirring shaft 16 through the electric telescopic rod 3, so as to stir and mix the photosensitive resin liquid for the second time until the extrusion plate 48 is contacted with the top of the mixing cylinder 10, after the photosensitive resin liquid in the mixing cylinder 10 is completely used, the extrusion plate 48 is pulled to the bottom of the mixing cylinder 10 through the electric telescopic rod 3, so that the second spiral stirring shaft 16 and the first spiral stirring shaft 20 are reset, meanwhile, the external thread on the top of the second spiral stirring shaft 16 is
