Sperra is a climate tech small business pioneering the next generation of solar, wind, and wave energy components using automated construction technologies. Sperra’s 3DCP R&D lab, the only known port-side 3DCP facility in the world, occupies a 5,000 ft² plot at AltaSea. AltaSea, a 400,000 ft² campus built on a historic pier at the Port of Los Angeles, offers convenient access to the deep ocean and hosts blue-economy technology demonstrations. AltaSea also offers hands-on educational programs in renewable energy, aquaculture, and underwater robotics.
This setting gives Sperra immediate access to marine testing and public engagement opportunities. Sperra’s facility includes concrete processing equipment such as core drills, saws, reinforcement bending machines, and a heavy-lift forklift. Sperra’s containerized, semi-mobile 3DCP platform was custom-built to manufacture renewable energy infrastructure components at laboratory and pilot scales. The 3D concrete printer has a 4.6 m diameter working range and can print concrete structures up to 3.4 m in height. It is equipped with a 100-seat license to ABB’s RobotStudio, enabling advanced simulation and offline programming for increased safety and productivity. The robotic arm is paired with an M-Tec Duo Mix 2000 automatic mixing pump, which requires only dry 3D concrete printing mix and water. Quikrete® supplies the primary concrete mix, with batch plants located nearby. Sperra has also acquired a gantry printer to be commissioned in fall 2024 through CyBe Construction. The printer will be installed at the expanded AltaSea plot, allowing for greater volume printing with the same precision as Sperra’s current system. Additionally, Sperra’s COBOD BOD XL 3-5-5 printer in Rochester, NY, expands its operations to the East Coast, with plans for future 3DCP facilities across the U.S.
