Abstract

The invention provides a 3D printing resin liquid combination for the dental department. The 3D printing resin liquid combination is prepared from the following raw materials in parts by weight: 35 to-65 parts of an acrylate oligomer, 15 to -35 parts of a diluent, 5 to -15 parts of a flexibilizer, 1 to -5 parts of a thickener, 0.1 to -1 part of a photoinitiator, and 0.4 to -4 parts of a photopromoter. By adopting the acrylate oligomer to be matched with the diluents, an assistant, the thickener and the like under effects of the photoinitiator and the photopromoter, finally the 3D printing resin liquid combination suitable for 3D printing is prepared, has the very high strength and liquidity, and is suitable for 3 D ink-jet printing in the field of the dental department.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a dental 3D printing resin composition, its preparation method and application. Background technique [0002] As an emerging technology in the field of rapid prototyping, 3D printing technology has a wide range of applications and is attracting more and more attention from the world. In the field of oral denture production, CAD / CAM, 3D printing technology, etc. can realize the automatic production of denture production, with high efficiency, less consumables, and low cost, which has changed the traditional production mode of dentures and has broad development prospects. It is a digital stomatology technology. An important link in the development process. [0003] The existing dental 3D printing resin products on the market have the disadvantage of low strength and cannot be used in the field of dentistry that requires high strength. Therefore, it is necessary to develop a high...
