Abstract: A method of in-space assembly includes: providing a roll of spooled high strength composite (HSC) boom, a robotic arm, and a printhead disposed at about an end of the robotic arm, the roll of spooled high strength composite boom feedingly coupled to the printhead; positioning the robotic arm; dispensing from the roll of spooled high strength composite boom a length of high strength composite boom; positioning again the robotic arm; dispensing another length of high strength composite boom from the roll of spooled high strength composite boom or from another roll of spooled high strength composite boom; joining by the printhead; and repeating said step of positioning to said step of joining until a desired structure is assembled in part or in whole. A system for in-space assembly and printhead to print struts for in-space assembly are also described.

Abstract: A self-deployable array of panels includes a plurality of panels, each panel having a first compressed panel thickness state and a second expanded panel thickness state, and including a spring bias element biased to the second expanded panel thickness state. A plurality of locking hinges hingedly couple each of the panels to an adjoining panel. Each locking hinge is biased to an open position. A release of stored potential energy of both of the spring bias element biased to the second expanded panel thickness state, and the locking hinges biased to the open position causes the self-deployable array of panels to self-deploy from a folded stowed state. A single part offset locking hinge is also described.

In a deployed doubly curved reflector state, each hinge. A doubly curved reflector for compact storage in a folded state and a locked open state, a method of manufacture, and a method for designing a substantially wrinkle free doubly curved foldable reflector having gores of a composite material are also described.
