TU eindhoven helps builders pioneer recyclable concrete constructions with giant 3D printer
the 3D printer will enable builders to make details as small as a pea, as well as create all kinds, qualities and colors of concrete, all in a single product.
TU eindhoven helps builders pioneer recyclable concrete constructions with giant 3D printer
to help push concrete construction into the future, TU eindhoven have began using an apparatus that enables objects of up to 11 meters long, five meters wide and four meters high to be created in a 3D printed format. the university will be working with the building industry to develop knowledge over the course of a number of years to print pioneering and easily recyclable concrete products and pavilions.

dutch company ROHACO built the 3D concrete printer, which looks a bit like an overhead hoisting crane in a production hall. first of its kind and size in the netherlands, the attached swivel head is connected to a hose that continues to a concrete mixer and pump unit.

in traditional concrete pouring, the formwork determines the ultimate shape of the concrete and that is quite unwieldy. free-form printing will enable builders to make details as small as a pea. another new possibility is to print all kinds, qualities and colors of concrete, all in a single product. for example, a complete wall can be printed with fiber-reinforced concrete to make it strong paired with an active insulation layer to retain heat and covered with a dirt-repelling concrete on the outside to keep it clean. it also means savings in terms of the internal and external outlet pipes of watertight concrete. TU eindhoven plan to help builders easily incorporate the individual requirements of users in the production process for years to come.

the technique can guarantee a watertight seal
with free-form maneuverabilit, curves can be easily created
structures can be as tall as four meters high
walls printed can be curved in great detail

the concrete 3D printer can create homes unsupervised
each layer can be mixed for a different purpose
patterns can be printed for specific structural needs
