Abstract: A 3D bioprinter having a visible light source to photocure biomaterial is disclosed. The 3D bioprinter prints visible light-curable biomaterial along with viable cells, and visible light photocures the biomaterial while maintaining cell viability. Visible light 3D bioprinter systems and methods of printing are further disclosed.

Abstract: The disclosure relates to a connector assembly including a male connector and a female connector that are connectable to each other. The male connector includes a connector main body having an annular shape and a plurality of male nubs arranged circumferentially around the connector main body, each male nub configured to be received by a corresponding female slot. The female connector includes a main body portion having an annular shape and a plurality of female slots arranged circumferentially around the main body portion, each female slot configured to receive a corresponding male nub. The male connector and female connector are configured such that when the male connector is connected to the female connector, the plurality of male nubs engages with respective ones of the plurality of female slots. The connector system is particularly applied to link building components together to form structural elements.

Abstract: In one embodiment, a modular assembly shelter kit is provided for rapid deployment in a remote location. The shelter kit includes headers, footers, upper horizontal beams, lower horizontal beams, roof, floor, and wall panels, and vertical support columns. The horizontal beams have notched hooks which form cross joints when engaged with notched hooks of adjacent horizontal beams. The cross joints can be placed against the headers or footers, and caged into position by prongs of the vertical support columns. The horizontal beams can also include grooves for holding interior and exterior wall panels, and interior ledges for holding roof and floor panels. Unique geometrically designed components deployed military or humanitarian responders with the ability to quickly manufacture and install such shelters in a wide variety of environments.
