The present invention discloses a three-dimensional printing device, comprising: a chassis, a light source and a controller, wherein a liquid storage tank is arranged in the middle of the chassis, an anti-sticking element is arranged on the inner wall of the liquid storage tank, and the liquid storage tank is used for holding polymerizable liquid; and further comprising: a base which is adapted to the liquid storage tank in a para-position way, wherein the base is connected with a driving device, and the light source is matched with the bottom of the base. By using the anti-sticking element as a covering part for the liquid storage tank, the forming part formed by curing the polymerizable liquid can lose contact with the anti-sticking element quickly and efficiently, so as to carry out further formation and processing operations. In this way, the whole three-dimensional printing process is more rapid and efficient. Meanwhile, the damage to the structure of the product or component caused by excessive adhesion during the separation of the formed product from the device component is effectively avoided, and therefore the processing effect of the product and the stable operation of the device component are ensured. The present invention further discloses a three-dimensional printing method using the above three-dimensional printing device.

3D printing device and 3D printing method

Disclosed herein are an adhesion blocking element, a three-dimensional printing device and a three-dimensional printing method. The adhesion blocking element comprises: one light-transmittable main body comprising a first surface and a second surface which are disposed opposite to each other, and side faces connecting the first surface and the second surface; and a plurality of microstructures arranged on the main body, wherein each microstructure has one cavity formed in the main body and one first open face which is arranged on the first surface of the main body and communicated to the cavity. The present invention decreases the adhesion between the adhesion blocking element and the cured layer by improving the structure of the adhesion blocking element itself, and eliminates the negative pressure adsorption between the cured layer and the adhesion blocking element, so that it is easier to peel the adhesion blocking element off from the cured layer. Meanwhile, the service life of the adhesion blocking element is prolonged by enhancing the local elastic deformability of the adhesion blocking element. In addition, the release layer adopted in the present invention is liquid, and the formed three-dimensional construct is solid, which makes the three-dimensional construct and the release layer more easily separated, thereby improving the speed of three-dimensional manufacturing.

Adhesion blocking element, three-dimensional printing device, and three-dimensional printing method

A 3D printer uses slides to illuminate the photocurable liquid. A slide carrier holds one or more slides that contain different patterns. To form each layer of a three-dimensional part, the corresponding pattern is projected onto the photocurable liquid, thus forming that layer. A controller switches the slides as needed, coordinating the slides with formation of the three-dimensional part.
