The working principle is as follows: firstly, the liquid material tank 6 with three primary colors is connected with the feeding pipes 8 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 8, then the photosensitive resin liquid of the liquid material tank 6 is squeezed into the mixing barrel 9 through the electric squeezing cylinder 38, for example, when the three primary colors are required to be used for color mixing, the gear 26 is driven to rotate through rotating the handle 5 in positive rotation, so that the rack 25 is driven to move towards the outer side of the feeding pipe 8, as the first scale line 30 at the top of the rack 25 corresponds to the second scale line 31 at the top of the material plate 29 inside the material control box 28, the material control plate 29 is pulled to move towards the inside of the feeding pipes 8, the discharging proportion of each feeding pipe 8 is controlled, and the proportion of the three primary colors is ensured to be 1: 1, it is spacing to mutually support through slider 32 and spout 33 simultaneously, thereby prevent to pull out accuse flitch 29 from controlling inside the magazine 28 completely, after the proportion calibration, through promoting stopper 36 on the pivot 27 to print pen body 4 inside along spacing groove 35, thereby extend from locking piece 34 to self-locking inside auto-lock groove 7, prevent that gear 26 from removing, influence the accuracy of proportion, when needing to evaluate the discharge amount accurately, for example when the photosensitive resin liquid that needs 10cm year, can control electric telescopic handle 2 through controller 3 and carry out work, thereby promote stripper plate 37 and move to compounding section of thick bamboo 9 top, move stripper plate 37 to the 10cm year position that scale 13 shows, thereby control the volume of material, when photosensitive resin liquid reaches 10cm year, promote accuse flitch 29 to controlling inside the magazine 28 through the cooperation of gear 26 with rack 25 through reversal rotation handle 5, prevent through rack 25 that the tricolor from continuing to get into mixing barrel 9 inside, then extend to self-locking groove 7 inside through self-locking piece 34 and carry out the auto-lock, carry out mixing barrel 9 inside back when photosensitive resin liquid, thereby control electric telescopic handle 2 through controller 3 and work, make stripper 37 extrude to mixing barrel 9 top, photosensitive resin liquid carries out first printing pen head 1 inside through guide hose 10 simultaneously, in the in-process that gets into first printing pen head 1 inside, thereby can also drive second helical stirring shaft 17 through mutually supporting of second helical stirring shaft 17 and mixing barrel 9 top thread groove and rotate, stir and mix photosensitive resin liquid, thereby drive second helical stirring shaft 17 and move to spread groove 16 inside, when second helical stirring shaft 17 and spread groove 16 top mutual contact, thereby mutually supporting through electric telescopic handle through the inner wall of second helical stirring shaft 17 and first helical stirring shaft 15 2 pushing the first spiral stirring shaft 15 to move towards the inside of the second spiral stirring shaft 17, so as to stir and mix the photosensitive resin liquid for the second time until the extrusion plate 37 and the top of the mixing barrel 9 are contacted with each other, after the photosensitive resin liquid in the mixing barrel 9 is completely used, pulling the extrusion plate 37 to move towards the bottom of the mixing barrel 9 through the electric telescopic rod 2, so as to reset the second spiral stirring shaft 17 and the first spiral stirring shaft 15, and simultaneously, the external thread on the top of the second spiral stirring shaft 17 is larger than the thread groove on the top of the mixing barrel 9, so as to prevent the second spiral stirring shaft 17 from falling off in the rotation process, and the second magnet 18 in the second spiral stirring shaft 17 is matched with the first magnet 14 in the first spiral stirring shaft 15, so as to prevent the first spiral stirring shaft 15 from falling off from the inside of the second spiral stirring shaft 17 in the rotation process, after the photosensitive resin liquid enters the inside of the first printing pen head 1, 3d printing is performed by the first printing pen head 1, during the printing process, the sizes of the calibers can be adjusted through the second printing pen point 21 and the third printing pen point 24 with different calibers, in the process of sleeving the
