AI Technical Summary
Technical Problem
3D printed articles made from UV curable acrylate formulations often lack desirable mechanical properties and are prone to fracture or degradation, leading to premature failure.
Method used
Incorporating additives with cyclopolymerizable functional groups separated by aliphatic or alkylene oxide linkers into polymerizable liquids, which can include oligomeric or monomeric curable materials, and using photoinitiators for polymerization via free radical mechanisms to enhance structural reinforcement.
Benefits of technology
The resulting 3D articles exhibit improved mechanical properties, including tensile modulus, tensile strength, and resistance to hydrolysis, with enhanced durability and resistance to degradation.
