Deployable reflector antenna includes a fabrication hub in which at least one additive fabrication unit disposed. The additive fabrication unit is configured to form at least one rigid structural element of a reflector antenna system. In a stowed condition, an RF reflector material comprised of a flexible webbing is disposed in a stowed configuration proximate to the fabrication hub. A fabrication control system controls the additive fabrication unit so as to form the at least one rigid structural element. The RF reflector material is arranged to transition during the additive fabrication process from the stowed configuration in which the flexible webbing material is furled compactly at the fabrication hub, to a deployed configuration in which the flexible webbing material is unfurled.
