Embodiment Construction

[0020] In order to allow those skilled in the art to better understand and realize the technical solution of the present invention, further detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 is a structural schematic diagram of the system for manufacturing three-dimensional objects according to the present invention, figure 2 yes figure 1 Side view of the cylinder block. Such as figure 1 figure 2 As shown, the system for manufacturing three-dimensional objects includes a laser 120 , a tank and a support platform 030 , wherein the tank includes a cylinder 020 and a resin replenishment cylinder 140 . The cylinder body 020 is filled with liquid resin material 010, and the top is embedded with a light-transmitting plate 070 corresponding to the laser 120. The light beam generated by the laser 120 can pass through the deflection mirror 130 and enter the cylinder body 020 through the light-transmit...

Abstract

The invention discloses a tank, a system and a method for manufacturing a three-dimensional body. The system comprises a laser, a supporting platform controller and the tank, wherein the tank comprises a cylinder for containing liquid resin materials, a resin supplement cylinder communicated with the cylinder body, and a light-transmitting plate; the light-transmitting plate is embedded at the top end of the cylinder body part; at least one air hole is formed in the part outside the light-transmitting plate region at the top end of the cylinder body; the cylinder body and the light-transmitting plate form a sealed space when the air hole is at a closed state. According to the invention, gas is led into the cylinder body containing the resin materials from the air hole in the top end of the cylinder, the liquid level of the resin materials is controlled to be at a set height, meanwhile gas is led into the resin supplement cylinder to ensure that the air pressure in the cylinder body and the air pressure the resin supplement cylinder are balanced, then the air hole in the top end of the cylinder body is closed, the air pressure in the resin supplement cylinder is adjusted to be supplemented to the cylinder body or the resin materials are removed during curing, and the height of the liquid level in the cylinder body is kept to be stable, so that the time required for flattening of the resin coated liquid level can be reduced, a film layer with uniform thickness can further be obtained, and the manufacture efficiency and accuracy of the three-dimensional body are improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional object manufacturing, in particular to three-dimensional manufacturing of photosensitive resin materials. Background technique [0002] Stereolithography is based on the principle of photopolymerization of liquid photosensitive resins, and is currently a relatively common 3D printing technology. The photocuring forming system usually includes a laser, a liquid tank for containing photosensitive resin, a controller, and a liftable object support platform. The liquid photosensitive resin is filled in a liquid tank, and the ultraviolet laser beam is scanned on the liquid surface under the action of the deflecting mirror. The scanning trajectory and the presence or absence of light are controlled by the controller. solidify. At the beginning of forming, the support platform is at a certain depth under the liquid surface, and the focused spot is scanned point by point on the liquid surface,...
