Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] see Figure 1-5 , a light-curing 3D printer, comprising a box body 1, a DLP projector 2 is fixedly installed in the inner cavity of the box body 1, a light-transmitting groove 3 is opened on the top of the box body 1, and tempered glass is fixedly installed on the upper surface of the box body 1 4. A liquid tank 5 is fixedly installed around the upper surface of the tempered glass 4, and the lower part of the inner side of the liquid tank 5 protrudes ob...

The invention relates to the technical field of 3D printing equipment, and discloses a light-curing 3D printer, which includes a box body, a DLP projector is fixedly installed in the inner cavity of the box body, and a light-transmitting groove is opened on the top of the box body. Toughened glass is fixedly installed on the upper surface of the box body, and a liquid tank is fixedly installed around the upper surface of the toughened glass. The light-curing 3D printer controls the alternating on and off of the two electromagnets when the liquid tank moves left and right through the hydraulic device, so that the scraper that attracts the magnet components rotates reciprocally under the alternating power off of the electromagnet, thereby controlling the rotation of the rotating sleeve. Driving the four scrapers can completely cover and slide the upper surface of the forming platform, so that after the forming platform rises, the liquid resin sticking to the surface of the forming platform can be scraped off in time, reducing the risk of forming the platform after the firmware is formed. It takes a lot of time to drip the resin after moving up and removing, which improves the use efficiency of the equipment.
Description
technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a photocuring 3D printer. Background technique [0002] The light-curing 3D printer irradiates the liquid light-curable resin with ultraviolet light or other light sources in a specific wavelength range and triggers a photochemical reaction, so that the light-curable resin in the area irradiated by the light source is solidified from the liquid state, and the object to be formed can be obtained after being cured layer by layer. , are widely used in industrial product concept design, rapid tooling manufacturing and medical applications. [0003] In the existing light-curing 3D printers, a certain amount of liquid resin is first injected into the liquid tank, the forming platform is matched with the cantilever, and the forming platform is horizontally matched with the liquid tank, and the rotation of the lead screw is controlled by the motor, and the cantilever is con...
