Abstract Three-dimensional (3D) hydrogel printing enables production of volumetric architectures containing desired structures using programmed automation processes. Our study reports a unique method resolution enhancement purely relying on post-printing treatment constructs. By immersing 3D-printed patterned consisting hydrophilic polyionic polymer network in solution polyions the opposite net charge, shrinking can rapidly occur resulting various degrees reduced dimensions comparing to...
Volumetric additive manufacturing (VAM) enables fast photopolymerization of three-dimensional constructs by illuminating dynamically evolving light patterns in the entire build volume. However, lack bioinks suitable for VAM is a critical limitation. This study reports rapid volumetric (bio)printing pristine, unmodified silk-based (silk sericin (SS) and silk fibroin (SF)) (bio)inks to form sophisticated shapes architectures. Of interest, combined with post-fabrication processing, (bio)printed...
The increasing demand in rapid wound dressing and healing has promoted the development of intraoperative strategies, such as bioprinting, which allows deposition bioinks directly at injury sites to conform their specific shapes structures. Although successes have been achieved varying degrees, either instrumentation remains complex high-cost or bioink is insufficient for desired cellular activities. Here, we report a cost-effective, open-source handheld bioprinter featuring an ergonomic...
Abstract Three‐dimensional (3D) bioprinting is driving significant innovations in biomedicine over recent years. Under certain scenarios such as intraoperative bioprinting, the bioinks used should exhibit not only cyto/biocompatibility but also adhesiveness wet conditions. Herein, an adhesive bioink composed of gelatin methacryloyl, gelatin, methacrylated hyaluronic acid, and skin secretion Andrias davidianus designed. The exhibits favorable cohesion to allow faithful extrusion conditions,...
