Abstract

The invention provides a photo-curing type 3D printing device and a printing method. The device comprises a shell, a bearing platform, a driving mechanism, an optical system and a pressure intensity adjusting element, wherein the shell is suitable for containing liquid photosensitive resin, and one end face of the shell comprises a light-transmitting panel; the bearing platform is arranged in the shell and used for bearing a formed workpiece; the driving mechanism is used for driving the bearing platform to move close to and away from the light-transmitting panel; the optical system comprises an exposure device which is located outside the shell and opposite to the light-transmitting panel, and the exposure device is suitable for irradiating a light beam pattern from the light-emitting side, so that a layer of liquid photosensitive resin, tightly attached to the light-transmitting panel, in the shell is controllably cured; and the pressure intensity adjusting element is arranged on the shell and used for adjusting the pressure intensity in the shell, and the pressure intensity adjusting element is used for reducing the ambient air pressure borne by the interior of the shell at least in the period that the bearing platform is away from the light-transmitting panel so as to separate the formed workpiece from the light-transmitting panel. The photo-curing type 3D printing device and the printing method are suitable for fine 3D model printing with high-precision requirements.

Description

Technical field [0001] The present invention relates to a three-dimensional (3D) printing apparatus, and more particularly to a photocurable 3D printing device. Background technique [0002] 3D printing technology, the computer three-dimensional design model is blue, and the model is layered by the software, using a laser beam, a hot melt nozzle, and the like, special materials such as metal powder, ceramic powder, plastic, and cell tissue are collapsed layer-by-layer bonds. Overlay molding, manufacturing entity products. Different from the traditional manufacturing, the final finished product is made by molding, cutting, etc., and 3D printing, 3D printing, the three-dimensional entity becomes a two-dimensional plane, and produces production and superimposing by layers by layer. It greatly reduces the complexity of manufacturing. This digital manufacturing mode does not require a complex process, no huge machine tool, does not require numerous human resources, directly from compu...
