­Sadly time does not heal all wounds. As the years accumulate, more and more body parts are damaged or lost. Replacement of these parts by transplantation has produced a mixed bag. The adaptation of 3-printing to biological tissues offers the hope of manufactured organs. However standard printing of hydrogels is slow with distorted parts and significant cell damage. Newer methods such as continuous liquid interface production (CLIP) speed up the process. Due to the physical aspects caused by the low fluidity resin used CLIP remains suitable only for small, thin-walled parts. Fast Hydrogel Stereolithography (FLOAT) printing developed here uses a highly fluid resin to increase velocity flow allowing a lower suction force during digital mask projection-stereolithography (MP-SLA) printing. It is capable of producing complex, hierarchical structures such as organs made with networks of vessels capable of supplying nourishing media. The process allows printing centimeter-sized hydrogel structures with embedded cells in minutes instead of the hours it would normally take.
