Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers

Advanced Materials Technologies, EarlyView.
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.

4D Printing of Multimaterial Flexible Magneto‐Active Polymers

Advanced Materials Technologies, EarlyView.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...

Harnessing Ultrafast Optical Pulses for 3D Microfabrication by Selective Tweezing and Immobilization of Colloidal Particles in an Integrated System

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...
