3D bioprinting is proving to be a fast-growing area of research, particularly for the eventual creation of human tissues and organs. One of the primary limitations on the area is due to hydrogels' inherent lack of strength. A recent article published on Nature Communications on April 28, called 'Reinforcement of hydrogels using three-dimensionally printed microfibers,' from researchers at Queensland University of Technology, in Brisbane, Australia, lays out a viable method of creating far more robust and stiff hydrogels. The research team discovered that by using a new 3D printed high-porosity microfiber technique, they could increase the stiffness of a hydrogel/scaffold composite by up to 54x, while maintaining an elasticity similar to human tissue.
