Abstract

The invention relates to a DLP printing photosensitive resin and specifically relates to a waterborne system DLP 3D printing photosensitive resin. The waterborne system DLP 3D printing photosensitiveresin comprises the following raw materials in parts by weight: 20-80 parts of waterborne polyurethane resin, 20-80 parts of waterborne monomer, 0.5-3 parts of photoinitiator, 0.01-0.05 part of de-foaming agent, 0.02-0.1 part of wetting dispersant and 0.02-1 part of pigment. According to the invention, the pollution problem of the present photosensitive resin is solved. The elongation at break ofDLP 3D printing photosensitive resin is effectively improved in the manner of adopting waterborne monomer and waterborne polyurethane resin as raw materials for preparing the waterborne system photosensitive resin.

Description

technical field [0001] The invention relates to a DLP printing photosensitive resin, in particular to a water-based system DLP type 3D printing photosensitive resin. Background technique [0002] 3D printing technology, also known as rapid prototyping manufacturing and additive manufacturing technology, has been frequently reported in major news reports in the past two years. However, the concept of 3D printing is not just emerging. Its core manufacturing idea first originated in the United States at the end of the 19th century. By the late 1980s, 3D printing technology had been developed and widely known. The reason why rapid prototyping manufacturing technology has become popular in a short period of time, and even known as the "third industrial revolution", is mainly based on "faster", "more refined", "less expensive" and "more suitable for industrial production". "It completely outperforms the existing industrialized production methods. The current 3D printing technolo...
