Abstract: A method of preparing a structure is provided. The method includes providing an initial structure; casting a first material in one or more void volumes of the initial structure; removing the initial structure from the first material; obtaining a cast structure comprising the first material; coating a second material on the cast structure; casting a third material using the coated cast structure; removing the first material; and obtaining a final structure. In various embodiments, the initial structure can include a first initial structure and a second initial structure and casting a first material in one or more first void volumes of the first initial structure and in one or more second void volumes of the second initial structure. In various embodiments, the method includes assembling the first cast structure and the second cast structure and obtaining an assembled structure comprising the first cast structure and the second cast structure.

Abstract: Provided herein is a system for producing a product. The system generally comprises a large-area micro-stereolithography system, an optical imaging system, and a controller in communication with the large-area micro-stereolithography system and the optical imaging system. The large-area micro-stereolithography system is capable of generating the product by optically polymerizing successive layers of a curable resin at a build plane. The controller is capable of directing the optical imaging system to obtain one or more optical images of the product or of a reference component located at the build plane, and adjusting a parameter associated with the large-area micro-stereolithography system based on the one or more images.

Abstract: Some embodiments of the disclosure disclose manifolds, microfluidic systems and methods that provide control over fluid flow distribution to an array of bio-scaffolds contained within the manifolds. In some embodiments, multiple perfusates may be injected into the manifold via multiple inlets where the manifold contains a bio-assembly with a substrate having a bio-scaffold disposed thereon. Biological investigations of the perfusates may then be conducted in the vascular components and chambers of the bio-scaffold.

Abstract: Provided herein is a system for producing a product. The system generally comprises a large-area micro-stereolithography system and a layer leveling system. The large-area micro-stereolithography system is capable of generating the product by optically polymerizing successive layers of a curable resin at a print plane. The layer leveling system is capable of flattening a non-flat region (such as a meniscus) of the curable resin in a vicinity of the build plane.
