Sombra Verde – a bamboo gazebo developed by AIRLAB and Singapore University of Technology and Design (SUTD) as part of Singapore’s Urban Design Festival 2018 – bridges this gap. The traditional raw bamboo poles, used extensively throughout Southeast Asia, are combined with 3D printed connectors, utilizing a series of new technologies.
By their very nature, bamboo poles vary in cross-section, thickness, and bend. In response to this, digital measurements were vital in achieving this structure. Each of the 117 poles was cut to length and digitized by the team. The information was then used to calculate the structural capacity and consequently its optimal position within the structure.
The data was then used in the design and fabrication of the 36 bespoke connecting pieces, and the material PLA was used to 3D print each individual element. An inexpensive and sustainable plant-based polymer, PLA’s properties make for an economical printing process, while the seamless, plastic node tightens on connection with the bamboo, the planned rotation enabling the structure to act as one.
The pavilion measures 8.50 x 6.50 meters with a height of 3.00 meters and weighs less than 150kg. Its transparent, green, cellular polycarbonate roof rests carefully upon the network of bamboo beneath, which itself meets the ground gracefully on three inverted tripod columns.
