Effect of 3D printing settings on the mechanical properties and biocompatibility of polymeric materials used for 3D direct printing of orthodontic aligners

Journal of Materials Research and Technology
The advent of the biocompatible resin Tera Harz TC-85 DAC (TC-85) introduces the potential for direct 3D-printed aligners via vat-polymerization, where photosensitive liquids are hardened layer by layer using a light source.

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

Advanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB

The influence of multifunctional dendritic oligomers on material properties for vat polymerization

Progress in Additive Manufacturing
Abstract Stereolithography is a state-of-the-art 3D-printing technology that has increasing impact in the dental, hearing-aid and bioprinting industries. The mechanical quality of the final product is highly dependent on the composition of the resin, polymerization kinetics and conversion rate achieved during the printing process (Watts in ...

Durability of Soft Pneumatic Actuators: A Review and Benchmarking Protocol

Advanced Robotics Research, EarlyView.
Lack of durability is a key challenge hindering the broad scale adoption of soft pneumatic actuators (SPAs) in automation industries. This review provides a comprehensive overview of existing research on SPA durability, introduces a standardized durability benchmarking protocol to consolidate the testing of SPAs, and outlines promising directions for ...

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

Angewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).
