Patent number: 11173656Abstract: An additive manufacturing system and an input material that overcomes that need to heat and extrude solidifying materials to create a three-dimensional structure. The system arranges subunits of the input material into repeating, interlinked subunits that can be arranged to manufacture a three-dimensional structure that is flexible but also has sufficient structural integrity to retain a desired shape during the additive manufacturing process or post-manufacturing usage. During the additive manufacturing process, the flexible input material can be manipulated and reformed to match the shape and structure of a target three-dimensional structure, upon which the manufactured three-dimensional structure is based. As elongated units of the input material are received by the additive manufacturing machine, the machine assembles the input material into the interlinked, repeating subunits, thereby removing the need to heat and extrude an input material to create a structure.Type: GrantFiled: February 7, 2019Date of Patent: November 16, 2021Inventor: Ivan Li Chuen Yeoh
