Oxygen supply sizing agent groove system and ceramic surface exposure 3D continuous printing method

Abstract

The invention discloses an oxygen supply sizing agent groove system and a ceramic surface exposure 3D continuous printing method. The oxygen supply sizing agent groove system comprises an oxygen supply device, a base plate, a connecting pipe, an air-permeable thin film and a sizing agent groove which is of a cylindrical structure; an annular protrusion is horizontally arranged on the inner wall of the sizing agent groove, the upper surface of an annular groove is covered with the air-permeable thin film, the annular groove is formed in the lower surface of the annular protrusion, the base plate is fixed to the bottom of the sizing agent groove, an annular seal structure is defined by the annular groove and the base plate, and a seal chamber is defined by the base plate, the annular protrusion and the air-permeable thin film; multiple through holes are evenly formed in the side wall of the annular protrusion, the annular seal structure is communicated with the seal chamber through the through holes, one end of the connecting pipe is connected with the oxygen supply device, and the other end of the connecting pipe passes through the wall surface of the sizing agent groove and the side face of the annular groove and is inserted into the annual seal structure. By means of the oxygen supply sizing agent groove system, the bonding problem of ceramic biscuits and base plates can be effectively solved, and thereby the continuous ceramic printing is achieved.

Description

technical field [0001] The invention belongs to the field of light-curing additive manufacturing, and relates to an oxygen supply slurry tank system and a ceramic surface exposure 3D continuous printing method. Background technique [0002] Additive manufacturing technology is a technology that uses the method of gradually accumulating materials to manufacture parts. Compared with traditional material removal processing technology, this technology is mainly used to process more complex and precise parts. In recent years, it has been used in aerospace, biomedicine, etc. It has been widely used in many fields. [0003] Photocuring technology is the earliest rapid manufacturing process in additive manufacturing technology. At present, there are two main types of photocuring technology: point-by-point scanning light curing (SLA) and surface exposure curing (DLP). The SLA process was applied earlier, but the production cost and equipment cost of its parts are very expensive, and...

Problems solved by technology

Surface exposure 3D printing technology is a method of whole-layer exposure curing for small-sized parts developed in recent years. This technology makes the equipment structure and process simpler, not only reduces the cost, but also has small deformation of the formed parts and faster molding speed. Fast, easy to achieve fine structure printing; but surface exposure technology also has some problems, such as the molded parts and the bottom are easy to bond and damage the printing process

At present, this technology is still in the development stage at home and abroad, and the solution to this problem is not perfect, and the continuous printing of parts cannot be realized.
