S25:E5 Precast Concrete Walls, 3D Printers, Telescopic Cranes, Kerosene Lamp Burners
First Aired: April 30, 2015
Runtime: 21 min
Steel reinforcement is positioned inside reusable moulds before concrete is poured and cured into prefabricated wall panels. Frames, motion systems, print heads and electronics are assembled and calibrated as 3D printers; nested boom sections and hydraulic equipment become telescopic cranes; and formed metal parts are joined with wick-adjustment mechanisms to make kerosene-lamp burners.
