Themed collection Materials Advances in Additive Manufacturing: from Processing to Applications

Cranioplasty remains associated with significant intra- and postoperative complications, with infection as the leading cause of implant failure.

Microfluidic-assisted 3D printing platform integrating a flow-focusing micromixer enables functionally graded porous hydrogels with smooth composition gradients that guide region-specific cell behavior to mimic complex tissue interfaces.

Spiropyran-containing formulations allow DLP printing of complex 4D mechanochromic structures. The printed tube turns from yellow to purple when compressed. Visible light restores color and shape, showing reversible behavior and sensing potential.

In this work different approaches to post-modification of 3D printed structures is explored, using photo-printing and RAFT polymerization. Surface or bulk modification can be achieved, expanding the scope of microfabrication techniques.

Cyclic olefin derivatives of tetracyclododecene with different pendant groups were evaluated as photo-ROMP resins using a latent Ru precatalyst activated by a chlorinated thioxanthone (CPTX, 1-chloro-4-propoxythioxanthone) upon exposure to light.

A novel materials-based strategy that bypasses alignment procedures by integrating ZnO nanoparticles into an LCE ink, enabling a simplified, direct-write 4D printing process.

Aliphatic photoinitiators based on α-ketoester moieties generate highly reactive and non-toxic radicals and can be used to initiate photopolymerization of (meth)acrylate and hydrogel resins for biomedical applications, outperforming commercial.

The time taken to reach key transition temperatures in MEX can be obtained using the cooling profile and thermomechanical transitions.

Photoresponsive polymeric hydrogel lattices have been generated using stereolithographic 3D printing to afford objects that can change shape when irradiated with UV-vis light that are capable of exhibiting payload release.
