Example Embodiment

[0023] Example 1

[0024] The light-curing 3D printer in Embodiment 1 includes a fuselage base, multiple resin cylinders, a lifting mechanism, multiple printing platforms, multiple projection panels, and multiple groups of curing light sources whose number is the same as the number of resin tanks. The plurality of resin cylinders are arranged on the top surface of the fuselage base. The lifting mechanism is arranged outside the plurality of resin cylinders. For example, the plurality of resin cylinders can be arranged around the periphery of the lifting mechanism, or arranged in parallel outside one side of the lifting mechanism. The plurality of printing platforms are respectively driven and connected to the lifting mechanism, and can be driven by the lifting mechanism to simultaneously move linearly in the plurality of resin cylinders along the height direction of the resin cylinder, and the printing surface of each printing platform parallel to the bottom surface of its co...

Abstract

The present invention relates to a light-curing 3D printer, wherein a light-curing 3D printer includes a fuselage base, multiple resin cylinders, a lifting mechanism, multiple printing platforms, multiple projection panels and multiple groups of curing light sources; multiple resin cylinders are arranged on The top surface of the base of the fuselage; the lifting mechanism is arranged outside the plurality of resin cylinders; the plurality of printing platforms are respectively driven and connected to the lifting mechanism, and can be driven by the lifting mechanism to move along the height of the resin cylinder in the plurality of resin cylinders at the same time. direction, and the printing surface of each printing platform is parallel to the bottom surface of its corresponding resin cylinder; the projection surfaces of multiple projection panels are respectively parallel to the printing surfaces of multiple printing platforms; multiple groups of curing light sources are respectively set on multiple projection The projection surface of the panel. Therefore, the present invention can print multiple products at one time, improve the efficiency and output of one printing, realize full utilization of the whole machine, reduce printing cost, and has simple structure, easy manufacturing and low manufacturing cost.

Description

technical field [0001] The invention relates to a photocuring 3D printer. Background technique [0002] 3D printer is a kind of printing equipment based on the cumulative forming technology based on the principle of discrete accumulation. It integrates computer-aided design and computer-aided manufacturing with the help of modern means such as computer, laser, precision transmission and numerical control. The 3D model can directly manufacture product models or samples in a very short time. [0003] There are many ways to form a 3D printer. One of them is to use photosensitive resin as a raw material to process the three-dimensional model of the part designed on the computer, triangulate the surface, store it in the STL file format, and process it in layers to obtain the interface of each layer. The two-dimensional contour information, and then the computer controls the DLP projector to project the two-dimensional contour image onto the resin layer, so that the corresponding...
