Problems solved by technology

[0004] The existing commonly used removal method for printing model supports is to put the printed model into a solution tank and then soak for a long time to remove the support on the model. On the one hand, the existing removal method takes a long time. The removal method is less effective, and prolonged soaking may even damage the thinner parts of the model; Separation of the printed model of the structure

[0034] Please refer to figure 1 , figure 1 A schematic structural diagram of the support removal device 100 provided in the first embodiment of the present invention.

[0035] The printing model 200 includes a model body 210 and a support member 230 connected to each other. The support member 230 is used to prevent the model body 210 from falling during the printing process. After the printing is completed, the support member 230 needs to be removed to obtain the model body 210 . The support removing device 100 is used to remove the support 230 of the printed model 200 , and its removal efficiency is high, and the support 230 can be separated from the printed model 200 .

[0036]The support removal device 100 includes a support removal tank 110, an agitator 120 and a model support 130, the agitator 120 includes a stirring drive member 125 and a stirring impeller 122 connected to each other, the stirring drive member 125 is installed in the support removal tank 110, and the mo...

[0062] Please refer to Figure 5 , Figure 5 A block diagram of the model printer 900 provided for the second embodiment of the present invention.

[0063] The model printer 900 includes a host computer 500 and a support removal device 100 as provided in the first embodiment. The host computer 500 is electrically connected to the controller 153, and the host computer 500 controls the activation or shutdown of the support removal device 100, so as to realize the printing of the support member 230 of the model 200. removal.

[0064] The operating principle of the model printer 900 provided by the second embodiment is:

[0065]The printing model 200 is fixed on the model support 130, the host computer 500 controls the support removal device 100 to start, and the dissolving solution 300 is added to the support removal tank 110 through the liquid distribution component 151, and the agitator 120 drives the dissolving solution 300 to advance to the printing model 200, so that the p...

[0069] see Figure 6 , Figure 6 A schematic block diagram of a support removal method provided in the third embodiment of the present invention; the support removal method is used to remove the support member 230 of the printing model 200 in the dissolving solution 300, and includes the following steps:

[0070] Step S101 , stirring the dissolving solution 300 , and forming a vortex and negative pressure to push the dissolving solution 300 toward the support member 230 . When the dissolving solution 300 advances toward the support 230 , the flow of the dissolving solution 300 near the printing model 200 is accelerated, and the removal efficiency of the support 230 is improved.

[0071] Step S102 , the dissolving solution 300 is rotated under stirring, and has a centrifugal force away from the printing model 200 , and the rotating dissolving solution 300 drives the supporting member 230 of the dissolving part to separate from the printing model 200 . On the one hand, the dis...

Abstract

The invention discloses a support removal device and method as well as a model printer and relates to the field of model printers. The support removal device is applied to removing a supporting pieceof a printing model in a dissolved solution and comprises a support removal groove, a stirrer and a model bracket; the model bracket is a hollow structure; the stirrer comprises a stirring drive pieceand a stirring impeller which are mutually connected; the stirring drive piece is installed in the support removal groove; the model bracket is installed in the support removal groove; the support removal groove is used for receiving the dissolved solution; the model bracket is used for bearing the printing model and enabling the printing model to be soaked into the dissolved solution; and the stirring impeller is used for stirring the dissolved solution. The support removal device has the beneficial effects that the removal efficiency is high, and the supporting piece can be separated from the interior of the printing model.

Description

technical field [0001] The invention relates to the field of model printers, in particular, to a support removal device and method and a model printer. Background technique [0002] When there is a suspended part in the printed model, or it has a nested structure, or when the printed model has a small bottom and a large top due to the different placement of the printed model, it is necessary to add supports to the printed model. Adding supports is mainly to prevent The printing material falls during the printing process, which affects the quality of the printed model and improves the success rate of the printed model. [0003] After printing the printed model with added supports, it is necessary to remove the supports in the printed model to obtain the designed printed model. The effect of removing the supports in the printed model will directly affect the quality of the printed model, so the supported The removal step is one of the critical steps in the production process ...
