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

Recyclable Thermoset Polymers for 4D Printing
TL;DR: In this paper , the authors integrated the dynamic covalent chemistries for 3D/4D printing, which will be thoroughly discussed in this article. And they are especially critical to be applied to thermosets and form a reversibly crosslinked network, making the thermmosets recyclingable or reprocessable as thermoplastics.
