Abstract
The field of 3D printing is continuing its rapid development in both academic and industrial research environments. The development of 3D printing technologies has opened new implementations in rapid prototyping, tooling, dentistry, microfluidics, biomedical devices, tissue engineering, drug delivery, etc. Among different 3D printing techniques, photopolymerization-based process (such as stereolithography and digital light processing) offers flexibility over the final properties of the 3D printed materials (such as optical, chemical, and mechanical properties) using versatile polymer chemistry. The strategy behind the 3D photopolymerization is based on using monomers/oligomers in liquid state (in the presence of photoinitiators) that can be photopolymerized (via radical or cationic mechanism) upon exposure to light source of different wavelengths (depending on the photoinitiator system). An overview of recent evolutions in the field of photopolymerization-based 3D printing and highlights of novel 3D print...

Rapid 3d continuous printing of casting molds for metals and other materials

TL;DR: In this article, a method of forming a 3D object useful as a casting mold is carried out by providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region there between; filling the build region with a liquid photocurable ceramic resin; irradiating the build regions through the optically-transparent member to form a solid polymer from the polymerizable liquid and advancing the carrier away from the building surface to form the three-dimensional object from the solid polymer.
