Problems solved by technology

It can be seen that the existing light-curing 3D printers can only print one product at a time, but cannot complete the manufacture of multiple products at the same time. The printing efficiency and printing output are low at one time, which is not conducive to the full utilization of the entire body

Embodiment 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 corresponding resin va...

Abstract

The invention relates to a photo-curing 3D printer comprising a printer body base, multiple resin cylinders, a lifting mechanism, multiple printing platforms, multiple projection panels and multiple groups of curing light sources. The multiple resin cylinders are arranged on the top face of the printer body base. The lifting mechanism is arranged outside the multiple resin cylinders. The multipleprinting platforms are connected with the lifting mechanism in a driven manner. The multiple printing platforms can be driven by the lifting mechanism to conduct rectilinear motion in the multiple resin cylinders at the same time in the height direction of the resin cylinders. The printing faces of the printing platforms are parallel to the bottom faces of the corresponding resin cylinders. The projection faces of the multiple projection panels are parallel to the printing faces of the multiple printing platforms. The multiple groups of curing light sources are arranged on the projection facesof the multiple projection face plates. In this way, the photo-curing 3D printer can print multiple products at the same time, improve the one-time printing efficiency and yield, achieves full utilization of the whole printer and reduces the printing cost, and the photo-curing 3D printer is simple in structure, easy to manufacture and low in 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...
