Large Portuguese Public Building 3D Printed in Record 9 Days Using COBOD Technology

Portuguese construction 3D-printing company Havelar has delivered a public building for the municipality of Matosinhos using construction 3D-printing technology. The project, a 500-square-meter recycling center office at the Ecocentro de Perafita in Porto, Portugal, was printed in 9 days on budget using a COBOD BOD2 construction 3D printer operated by a four-person crew.

The structure incorporates curved walls throughout — a feature that would add significant cost using conventional formwork, but which construction 3D printing produces directly from the digital model at no additional labor or material cost.

Havelar has continued to build on this project’s success. Since completing the recycling center, the company has printed 32 housing units in Porto, and 53 additional houses are scheduled for construction later in 2026, extending construction 3D printing to residential applications across different regions of the country.
