AI Technical Summary

Technical Problem

Existing 3D printing materials, particularly UV curable acrylate formulations, often result in 3D printed articles with poor mechanical properties, leading to premature failure and degradation.

Method used

A polymerizable liquid comprising an acrylate component, a composite resin with polymer particles dispersed in a curable carrier, and a photoinitiator, which undergoes polymerization upon irradiation to form a polymer composite with improved mechanical properties.

Benefits of technology

The solution produces 3D printed articles with high resolution and desirable mechanical properties, including impact resistance, tensile strength, and flexural modulus, enhancing the durability and performance of the printed articles.

Abstract

To provide polymerizable liquids which can produce 3D printed articles of high resolution and desirable mechanical properties, including cases where the polymerizable liquids are used as a build material or ink.SOLUTION: Polymerizable liquids are described herein which, in some embodiments, can produce 3D printed articles of high resolution and desirable mechanical properties. In one aspect, a polymerizable liquid comprises an acrylate component, and a composite resin comprising a curable carrier and polymeric particles dispersed in the curable carrier. The polymerizable liquid also comprises a photoinitiator component.SELECTED DRAWING: None
