Abstract

The invention discloses a 3D (three-dimensional) printing light-cured resin and a preparation method thereof. The 3D printing light-cured resin is prepared from the following components in parts by weight: 50 to 70 parts of acrylic resin oligomers, 20 to 40 parts of a reactive diluent, 1 to 10 parts of a photoinitiator, 1 to 10 parts of a coloring agent and 0.1 to 5 parts of a flatting agent. The 3D printing light-cured resin disclosed by the invention has the advantages of high light sensitivity and fast forming speed; the purpose of enabling resin monolayer curing time to be within 0.5s can be realized; 3D printing equipment can achieve a forming speed of 220 to 360mm / h; and the processing efficiency of the 3D printing equipment is greatly improved.

Description

technical field [0001] The invention relates to the field of photocurable resins, in particular to a 3D printing photocurable resin suitable for rapid curing of molecular sieve ultrafast 3D printing equipment and a preparation method thereof. Background technique [0002] Since the emergence of 3D printing technology in the 1980s, 3D printing equipment suitable for different fields and with different functions have been developed at home and abroad. The 3D printing equipment of DLP (Digital Light Processing, digital light processing) technology is a very important one among many technical routes. At the same time, the ultra-fast 3D printing equipment improved by molecular sieve is an upgraded product in terms of processing efficiency of traditional DLP technology 3D printing equipment. Therefore, this kind of molding requires 3D printing photocurable resin to be highly sensitive to light and capable of curing in a short time. [0003] At present, the 3D printing photocurab...
