Problems solved by technology

[0003] The disadvantage of the above technology is that the liquid surface on the liquid in the curing tank is scanned by using a beam of light, which has extremely high requirements on the flatness of the liquid surface, and the whole machine needs to strictly control t

Example Embodiment

[0025] Example 1, combining figure 1 , Install the 1 developing module at the bottom of the 2 container slot, the 2 container slot is placed vertically, and the 3 working platform is installed on the 4 screw, the 4 screw is connected with the 5 lifting motor, and the power is obtained through the 5 lifting motor. Drive the 3 working platform to move up and down in the 2 container tank.

Example Embodiment

[0026] Example two, in order to further illustrate the present invention, it is now combined figure 1 , figure 2 , image 3 The printing method involved in the present invention will be further explained.

[0027] The first step is to inject the light-curable material into the 2 container slots, the second step is to input the first layer of the three-dimensional shape that needs to be printed into the 1 developing module through the computer, and the third step is adjusted by 4 screws according to the required printing thickness. The position of the working platform, the fourth step is to project the light emitted by the 6 light source located under the 1 developing module to the 1 developing module, and then the light passes through the 1 developing module and irradiates the light curing material, which is irradiated by the light From liquid to solid, the fifth step repeats the second to fourth steps until the printed layer is manufactured, and a three-dimensional entity is ob...

Abstract

The invention discloses a light curing 3D printing device and printing method using light curing materials as raw materials. The printing device comprises a container groove, a developing module, a working bearing table, a screw rod, a lifting machine and a light source; the developing module is arranged at the bottom of the container groove, and the developing module and the container groove are fixedly arranged together. The printing method comprises the following steps that firstly, liquid-state photosensitive resin is injected into the container groove; secondly, a shape required to be printed is input to the developing module through a computer; thirdly, according to the thickness required to be printed, the position of the working bearing table is adjusted through a screw rod; fourthly, light emitted by the light source passes through the developing module, at the moment, the developing module carries out local blocking on the light projected by the light source, the unblocked photosensitive resin is in contact with the light, and the resin is converted into the solid state from the liquid state; fifthly, the screw rod on the working bearing table obtains power through a lifting motor to move upwards; and sixthly, the step two to the step four are repeated until a printing layer face is manufactured.

Description

technical field [0001] The invention belongs to the field of printing, and in particular relates to a light-curing 3D printing device with simple mechanism and convenient operation and a printing method thereof. Background technique [0002] The existing photocuring technology is based on the principle of photopolymerization of liquid photosensitive resin. First, the photosensitive resin is injected into the curing tank, and then the laser beam scans the photosensitive resin from top to bottom through the optical deflection crystal from the top of the curing tank. The scanning trajectory and the presence or absence of light are controlled by the computer. Where the light spot hits, the photosensitive resin changes from liquid to solid when it encounters light, and then the working platform is lowered by one level, and then the next level is scanned, and so on. Until the entire workpiece is manufactured, a three-dimensional solid workpiece is obtained. [0003] The disadvant...
