Havelar uses COBOD BOD2 3D printer to build 500 m² municipal office in nine days

Portuguese construction firm Havelar has completed a 500 m² recycling center office at the Ecocentro de Perafita in Porto for the Matosinhos municipality using a COBOD BOD2 3D printer. The project required a four-person crew and nine working days, with the structure delivered on budget. The building serves as an administrative office for a recycling facility, marking one of the larger public-sector construction 3D printing projects in Southern Europe to date.

This project demonstrates that construction-scale extrusion AM is moving beyond demonstration houses into functional municipal infrastructure. COBOD's BOD2 system, a gantry-style concrete printer, competes primarily with ICON's Vulcan platform in the US and Peri's 3D construction printing systems in Europe. The key differentiator here is speed and labor efficiency: a 500 m² structure completed in nine days with four workers is a meaningful data point against conventional block-and-mortar construction timelines. The project also benefits from being a public-sector commission, which provides a referenceable case for other municipalities evaluating AM for civic buildings. The value chain position is clear: COBOD supplies the hardware, Havelar provides the construction service and local permitting expertise, and the municipality gains a cost-certain, fast-delivery asset.

For COBOD, the practical next step is converting this reference into repeat municipal contracts across Portugal and neighboring markets. For the broader construction AM segment, the takeaway is that speed-to-completion and labor reduction are the most defensible value propositions against traditional methods, not material novelty or architectural complexity. Havelar's ability to deliver on budget is the metric that will matter most for future public-sector adoption.
