Abstract: A 3D printing system for 3D printing of concrete buildings or other concrete structures. A set of cable support masts are temporarily installed at corners of a two-dimensional footprint area of any given level of a multi-level building to enable 3D printing of wall sections or other structural components of that given level of the building using a cable-guided concrete dispensing nozzle suspended from said cable support masts by a set of movable, motor-driven positioning cables. The building is built in stage-wise fashion, level-by-level, with the set of support masts being moved up level-by-level as the levels of the building are completed. The construction of the building is not dependent on a set of ground-level towers distributed around the ground-level footprint of the building, thus notably reducing equipment requirements for the 3D printed construction of tall, multi-storey buildings.

Abstract: A system for forming a deep drawn helmet and method therefor are disclosed. The system includes a forming draw ring and a non-forming draw ring and supports a prepreg stack between a forming aperture of the forming draw ring and a non-forming aperture of the non-forming draw ring. The system clamps a flange portion of the prepreg stack between a contact surface of the forming draw ring and a contact surface of the non-forming draw ring, which forms a clamped assembly of the rings and the prepreg stack. The system then forms a deep drawn helmet preform from the prepreg stack of the clamped assembly. The same system or a different forming system then consolidates one or more of the preforms into a final deep drawn helmet. The system can control sliding of the flange during forming of the helmet preform without reducing the flange clamping force.
