AI Technical Summary
Technical Problem
In dental applications, photosensitive resins are prone to settlement problems due to low viscosity and the addition of white slurry, which affects the printing accuracy and scratch resistance of the material.
Method used
The organic silane-modified polyether polyurethane acrylate and photocurable nano-white paste are used to improve the settlement resistance of the photosensitive composition and the wear resistance of the cured resin material by combining the modified polymer and the nano-white paste.
Benefits of technology
It effectively alleviates the settlement problem of photosensitive resin, improves printing accuracy, and makes the cured resin material have high wear resistance.

Abstract
The invention provides an anti-settling 3D printing photosensitive composition as well as preparation and application thereof, and the anti-settling 3D printing photosensitive composition comprises the following components in parts by weight: 30-40 parts of organosilane modified polyether urethane acrylate; 20 to 30 parts of photocurable nano white paste; 25 to 48 parts of a reactive diluent; and 2-5 parts of a photoinitiator. According to the 3D printing photosensitive composition provided by the invention, the organosilane modified polyether urethane acrylate and the photocurable nano white paste are simultaneously introduced into the 3D printing photosensitive composition provided by the invention, so that the photosensitive composition has relatively good settling resistance, and a cured resin material has relatively high wear resistance.
