Problems solved by technology

However, this control method requires the use of a membrane that allows oxygen to pass through. The thickness of the membrane is about 0.1 mm, which is easy to wear and tear. and deformed shape cannot be controlled, so the printing accuracy is low

Abstract

The present invention provides a rapid 3D printing system, comprising a titanium dioxide window (1), an uncured layer (2), a photosensitive resin (3), a material trough (4), an optical device (5), an object stage (6), In the motor (7) and the cured product (8), the titanium dioxide window (1) is located at the bottom of the material tank (4); the photosensitive resin (3) is arranged inside the material tank (4). Beneficial effects of the present invention: during the printing process, an uncured layer is formed at the interface between the titanium dioxide window and the photosensitive resin, which can effectively avoid the mechanical peeling of the cured body and the refilling process of the photosensitive resin in traditional 3D printing, and realize continuous printing, thereby The printing speed is faster than that of traditional photosensitive resin 3D printing, which is 20 to 100 times faster than that of traditional 3D printing; at the same time, compared with CLIP technology, the thickness of the titanium dioxide window is 1 mm to 90 mm thick during the printing process. It is not easy to crack and deform under the action of force, so the printed products have higher precision, and the printing speed is comparable to the latest CLIP technology, which can reach 600 mm / h.

Description

technical field [0001] The invention relates to a fast 3D printing system, which belongs to the technical field of printing. Background technique [0002] Generally, 3D printing is a technology of manufacturing three-dimensional products by adding materials layer by layer. This technology is a combination of cutting-edge technologies in many fields and is known as the core technology of the "third industrial revolution". Among them, the light-curing 3D printing rapid prototyping process has the characteristics of low energy consumption, low cost, and high forming precision. At present, the traditional photocuring 3D printing technology finally obtains a 3D entity by layer-by-layer stacking. This method makes the accuracy of the printed product restricted by the layer thickness; Long print cycles due to photoresin leveling time (top-down printing) or the need to mechanically peel the cured layer from the tank inner floor and resin refill (bottom-up printing).
