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...read more

TL;DR: In this article, the influence of aging in artificial saliva of additive manufacturing (AM) orthodontic composites on their functional properties was investigated. And the results showed that not only the chemical composition and structure, but also aging have a great impact on the indentation hardness and wear resistance of the tested orthodentic materials.

Scattering Model for Composite Stereolithography to Enable Resin–Filler Selection and Cure Depth Control
TL;DR: Fillers are used to modify the properties of the photoresins used in stereolithography (SLA) as discussed by the authors, and the resulting composite formulations tend to have a decreasing cure depth for increasing particle load.
