3D printing advantages

Printing a lost formwork, filled with UHPFC and coated, greatly reduces waste and cost, for a flawless aspect.

XtreeE mission

XtreeE co-designed this structure with Marc Dalibard architect and EZCT Architecture & Design Research (Philippe Morel, Felix Agid), and then produced the 3D printing files as well as the moulds. The casting was carried out by Fehr Architectural with concrete from LafargeHolcim.
