WASP complete an extremely lightweight skeletal 3D printing building
Aug 02, 2018

The result is an information-rich, elaborate cellular microstructure derived from the trabecular bone structure. ACTLAB aptly refers to this novel arrangement as a "functional gradient Trabeculae Pavilion", referring to the Trabeculae Pavilion's load response system, which has spatial variation characteristics of interconnected solid pillars.

The bionic design also features a striking bullet-proof shell in homage to the famous Felix Candela lightweight structure. The slender free edge shape combines with the load - driven structure of the skin to form a unique grid pattern, elegant and practical.

ACTLAB's use of fused deposition molding (FDM) is critical to achieving this advanced structure. 352 individual components were printed in 3D on four DeltaWASP 4070 and DeltaWASP 60100, followed by an integrated joiner system. The delegates used the WASP 3D printer and the experimental WASP Spitfire extruder to run five WASP 3D printers 24 hours a day. The whole exhibition hall was completed in 4,352 hours (181 days).

"Demand for raw materials has grown exponentially in the past few decades due to rapid urbanization and industrialization in emerging economies," said Roberto Naboni, an architect and assistant professor at the university of southern Denmark. "This study looks at the opportunities provided by biological models and new materials manufacturing technologies to find sustainable materials development solutions. Our goal is to explore a new architectural model: advanced, efficient and sustainable.

The building area is 7.5 meters x 6.0 meters x 3.6 meters, covering an area of 36 square meters and weighing 335 kilograms. After studying various thermoplastic composites, ACTLAB began to use a new type of biopolymer produced by FILOALFA because of its ideal weight-strength ratio and other mechanical properties.
