Embodiment

[0036] Such as figure 1 , 2 shown. The invention discloses a micro-projection light-curing printing device with doubled single printing area, comprising a linear guide rail 1, a light source system 2, an optical projection system 3 and a transparent resin tank 4 for containing photosensitive resin;

[0037] The transparent resin tank 4 is arranged above the linear guide rail 1 and parallel to the linear guide rail 1;

[0038] The light source system 2 and the optical projection system 3 are arranged between the transparent resin tank 4 and the linear guide rail 1 from bottom to top;

[0039] A drive mechanism is provided on the linear guide rail 1; through the drive mechanism, the light source system 2 and the optical projection system 3 are moved to a predetermined position along the track of the linear guide rail 1;

[0040] The light source system 2 is used to emit multiple beams of parallel light to illuminate the optical projection system 3;

[0041] The optical proje...

Abstract

The invention discloses a micro-projection photo-curing printing device and method with a doubled single-time printing area. The micro-projection photo-curing printing device comprises a linear guide rail, a light source system, an optical projection system and a transparent resin groove for containing photosensitive resin, wherein the transparent resin groove is formed above the linear guide rail and is parallel to the linear guide rail; the light source system and the optical projection system are arranged between the transparent resin groove and the linear guide rail from bottom to top; the linear guide rail is provided with a driving mechanism; and the light source system and the optical projection system are driven through the driving mechanism to move to a pre-set position along a track of the linear guide rail. According to the device disclosed by the invention, the light source system and the optical projection system are driven through the driving mechanism to move on the linear guide rail to reach a first printing position and a second printing position of each layer of pattern; and two pieces of sub-pictures are spliced. By adopting a simple and feasible technical means, an actual printing size can be doubled and high-precision printing can be realized; and a plurality of camera lenses or high-pixel chips do not need to be utilized, so that the cost is reduced.

Description

technical field [0001] The present invention relates to light-curing 3D printing, in particular to a micro-projection light-curing printing device and method that doubles the printing area for a single time. Background technique [0002] Teeth are one of the indispensable organs of the human body. However, due to diseases, sports trauma or congenital development, modern people have early chipped, broken, missing, deformed teeth, etc., and need to seek medical treatment for various dental restorations. Clinically, the first step in tooth restoration is to make a patient's tooth or a full-mouth dental model. The traditional method is to first make the patient's oral cavity impression by dental model technology, and then copy the plaster model by professional technicians. The production of dental models by this method not only highly relies on the manual skills of dental technicians, but the whole process is very long, expensive and labor-intensive, and errors are prone to occ...
