A research team has explored a novel 3D printed plastic formwork to produce optimised ribbed floor slabs in an efficient manner. The new approach uses 40 percent less concrete, while offering the same structural performance. Credit: ETH Zürich #3dprinting #research #engineering

@ETH It is better to build with wood and isolation made with plants. This way you store 50% CO2 and prevent 40% CO2 production when making concrete and rock wool or glass wool.

@ETH great, it only took 3 times longer and two times more expensive ..... definitely worth it.

@ETH Is concrete that expensive that it's worth all that micro management, manpower and equipment?

@ETH Why don't you just use glass fiber reinforced concrete instead of rebar? Then you could print the mold normally and just fill it.
