Abstract: Embodiments of the present disclosure include methods of simultaneously manufacturing two or more hydrogel constructs (e.g., tubular hydrogel constructs). In some embodiments, the method comprises one or more of the following steps: providing a vat comprising a bio-ink composition containing one or more monomers and/or one or more polymers; applying electromagnetic radiation from an electromagnetic radiation source to cure a layer of the hydrogel constructs (e.g., tubular hydrogel constructs); and applying electromagnetic radiation from the electromagnetic radiation source one or more additional times to produce one or more additional layers of the hydrogel constructs (e.g., tubular hydrogel constructs).

Abstract: The present disclosure provides reinforced hydrogel structures, methods of reinforcing hydrogel structures, and methods of treating ischemic disorders using the reinforced hydrogel structures.

Abstract: Apparatus and method for forming a three-dimensional object. The apparatus includes a platform on which the three-dimensional object is formed. The apparatus includes an oxygen soluble liquid having a build surface. The build surface and the platform define a build region therebetween. The apparatus includes a photosensitive liquid disposed on the oxygen soluble liquid. The density of the oxygen soluble liquid is greater than the density of the photosensitive liquid. The apparatus includes an optically transparent member. The optically transparent member supports the oxygen soluble liquid. The apparatus includes a radiation source configured to irradiate the build region through the optically transparent member and the oxygen soluble liquid to form a solid polymer from the photosensitive liquid. The apparatus includes a controller configured to advance the platform away from the build surface.
