Design and production of a 3D printing marine ecological structure

Drawings for the slab and gantry (formwork and reinforcement plans) confirmed the importance of reinforcement ratios in reinforced concrete to enable the assembly to be lifted and to withstand high hydrodynamic forces without significant movement. Reinforcement was used in the slab and columns up to HA25 diameter:

• slab: 190 kg/m ³ ;

• columns and walls: 295 kg/m ³ ;

• beams: 241 kg/m ³ .

The 3D-printed reef walls had already been cut into different modules during the upstream design phases, particularly in terms of height, with the 3.80 m walls divided into two heights: the first, 2 m high, and the second,...
