A method for forming a heated thermoplastic composite material into a closed profile using a tooling includes a) forming, during a first forming stage, a heated thermoplastic composite in a first space between a male tooling part and a female tooling part, b) forming, during a second forming stage, the thermoplastic composite material by engaging a first segment and/or second segment of the thermoplastic composite material with at least one auxiliary tooling part to thereby bring the first and second segments closer together, and c) forming, during a third forming stage, the thermoplastic composite material by pressing, using a pressing tooling part, the thermoplastic composite material around the male tooling part thereby creating a seam between the first and second segment.

Inverse origami design for soft robotic development is described herein. A method as described herein can include determining, by a system comprising a processor, shape parameters corresponding to an input shape; generating, by the system based on the shape parameters, an origami crease pattern representative of the input shape, wherein the origami crease pattern comprises respective origami cell units, and wherein the origami crease pattern is defined by a group of vector size parameters corresponding to relative fold lengths associated with the respective origami cell units, a vector angle parameter corresponding to fold angles associated with the respective origami cell units, and a scalar cell height parameter; and imprinting, by the system, the origami crease pattern onto a tangible medium.

The present invention provides constructs including a tubular biodegradable polyglycolic acid scaffold, wherein the scaffold may be coated with extracellular matrix proteins and substantially acellular. The constructs can be utilized as an arteriovenous graft, a coronary graft, a peripheral artery bypass conduit, or a urinary conduit. The present invention also provides methods of producing such constructs.
