Wasp, an Italian 3D printing company, announced that the Trabeculae pavilion had been completed. Lightweight structure, bionic design, combined with streamlined shape, full of sense of science and technology! This exquisite pavilion was designed by ACTLAB, the architectural computing technology laboratory of the school of architecture of Milan polytechnic university, the original intention of efficient, lightweight and sustainable design was perfectly achieved.

       The interior of the pavilion adopts an organic skeleton structure - a finely crafted cellular microstructure. ACTLAB believes that this structure is not only creative, but also meets the requirements of materials and structures for load bearing, it is called " functional trap structure". The whole structure adopts a lightweight design, the shell is crack - resistant, the line is elegant, the edge is fine and non - trace, and the transition between the point line and the surface is natural, which is the top grade in the design.

The processing of the pavilion uses the melt deposition molding ( FDM ) technology, the application of this technology is crucial to the processing of the structure. ACTLAB printed 352 separate parts and then assembled them into a single unit. According to the introduction, the pavilion was run 24 hours a day by five wasp 3D printers and completed after 4,352 hours ( 181 days ) of printing.
The volume of pavilion is 7.5 *6.0 *3.6 m , covers an area of 36 square meters, and weighs 335 kilograms. After studying various thermoplastic composites, ACTLAB decided to adopt the new biopolymer produced by filo alfa because its weight, strength and mechanical properties were ideal.
