In recent years, 3D printing has expanded its applications from rapid prototyping and hobbyists to various industries, research fields and everyday life. The focus has shifted towards the development of equipment, software, and materials, especially in the field of light-activated 3D printing which relies on photocurable formulations and rapid solidification via photopolymerization. This article analyzes and explains the chemical aspects of preparing a formulation for light-induced 3D printing, aiming to provide more tools for the development of innovative photocurable materials for 3D printable devices.
In the last few years, 3D printing has evolved from its original niche applications, such as rapid prototyping and hobbyists, towards many applications in industry, research and everyday life. This involved an evolution in terms of equipment, software and, most of all, in materials. Among the different available 3D printing technologies, the light activated ones need particular attention from a chemical point of view, since those are based on photocurable formulations and in situ rapid solidification via photopolymerization. In this article, the chemical aspects beyond the preparation of a formulation for light-induced 3D printing are analyzed and explained, aiming at giving more tools for the development of new photocurable materials that can be used for the fabrication of innovative 3D printable devices.
