WASP has completed the construction of a 3D printed airport services building, named Ol Casél, at Milan Bergamo Airport in Italy. The project was executed in partnership with construction firm EDILCO and airport operator SACBO, utilizing the Crane WASP system. The printing process spanned 7 days of the 19-day total construction timeline, employing a lime-based mortar material. The Crane WASP hardware features a build volume of 8,200 mm by 3,200 mm, a twin-screw extrusion system, and a maximum print speed of 200 mm/s, designed to integrate structural oclusions for utility routing.

This project highlights the utility of large-scale extrusion-based additive manufacturing in infrastructure applications, moving beyond residential housing into specialized, remote, or difficult-to-access site development. While competitors like ICON and COBOD focus heavily on residential housing markets, WASP continues to differentiate its value proposition by emphasizing material versatility, specifically earth-based and lime-based mortars, rather than standard Portland cement. This focus on sustainable, low-carbon materials addresses the growing regulatory pressure in the European construction sector to reduce the carbon footprint of infrastructure projects.

For construction firms, the primary takeaway is the successful integration of functional utility channels directly into the print path, which reduces secondary labor requirements. Future adoption of this technology in commercial infrastructure will depend on the standardization of these lime-based mortars to meet local building codes and the ability to scale the Crane WASP deployment for larger, multi-story structural requirements.
