Title:
HIGH-SPEED RESIN COATING 3D PRINTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/056720
Kind Code:
A1
Abstract:
Disclosed is a high-speed resin coating 3D printing system. The 3D printing system comprises an exposure optical system (1), a film (5), a laser displacement meter (3), a rotating knife (4), a bubble scraper (8), a resin tank (6), and a sample holder (7). The sample holder (7) is connected to an ascending and descending device. The sample holder (7) is disposed in the resin tank (6), and the film (5) is covered on a resin in the resin tank (6). The resin tank (6) is mounted on a three-dimensional motion control shaft. The exposure optical system (1) is disposed above the resin tank (6). A projection lens of the exposure optical system (1) is pointed toward the film (5), and the projection lens is sleeved with an electromagnetic coil (2). The laser displacement meter (3) is disposed at a side of the projection lens. The rotating knife (4) is disposed above the film (5), and the bubble scraper (8) is disposed beneath the film (5). The solution of the present invention enables processing at a high speed and in a large area, and provides a magnetic field for controlling a magnetization direction of a magnetic resin during the printing process. The present invention can increase the speed of existing resin-based 3D printing, and permits the use of a solid-liquid mixed resin having a high viscosity or a high content.
