The 3D concrete printed (3DCP) dwellings are in Grange Close, Dundalk, County Louth, Ireland. The 330m² footprint includes three three-bedroom houses.

Designed to meet Eurocode 6 masonry standard, the boundaries of the housing development are composed of cavity walls: two 10cm-thick skins with a 150mm cavity in-between. Cobod, the Denmark-based 3D printer provider, said the walls were constructed without reinforcement and meets EN206, Eurocode 6 for unreinforced masonry construction and ISO/ASTM (52939:2023) standards.

鈥淭he use of the 3DCP technology meant 35% faster construction and completion in just 132 days compared to conventional methods requiring more than 200 days, with the 3D printed superstructure completed in just 12 printing days,鈥� claimed Cobod. 鈥淎pproximately 50% of the time savings came directly from 3D printing the wall system.鈥�

The printing firm added that remaining savings were achieved alongside what could be called a modular approach. Referring to 鈥渢he precision of 3D construction printing鈥�, Cobod said it was able to employ 鈥渟eamless integration of other building components 鈥� such as partition walls, floor systems, and trusses 鈥� to already be considered during the planning and preparation phases, resulting in a more efficient construction process.鈥�
