Convergence of Organ‐on‐a‐Chip and Freeform Printing of Sacrificial Poly(2‐cyclopropyl‐2‐oxazoline) Enables the Generation of Perfusable Endothelialized Channels in Hydrogels

Macromolecular Rapid Communications, EarlyView.
We employ freeform printing of thermo‐responsive poly(2‐oxazoline) to directly fabricate suspended sacrificial vascular templates within Organ‐on‐a‐chip devices. This enables circular, perfusable channels down to 200 µm without post‐processing.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.
