TPE

Description

This TPE-based high-strength and flexibility elastomer is ideal for topologically optimized pliable structures, such as cushions and seating. It is tested up to 90 Shore A and 80°C (176°F) as working temperature, and it is extensively used to print large-scale rubber-like parts for furniture, seating, and design-related components.

Color: Natural white
Ideal for large rubber-like topologically optimized pliable structures, like cushions and seating extruders HA, HV, HF

Case Study

Domino 3.0: Generated Living Structure” designed by Kengo Kuma & Associates for the Biennale Architettura 2025, is an architectural synthesis that explores the dialogue between nature and advanced production, showing how robotic additive manufacturing technologies and organic elements can redefine the future of construction.

Concept development
The creative inspiration behind the project originates from Storm Vaia, which ravaged the forests of northern Italy in 2018, uprooting thousands of trees. In response to this immense natural devastation, architect Kengo Kuma salvaged several of these fallen trunks, transforming them into raw materials to reinterpret the very essence of architecture. Once recovered from the forest, the logs were 3D scanned by D3 Wood to capture the unique features of their organic shapes. This digital analysis enabled the design of custom joints, turning the irregular timber into components suitable for architectural construction.

Initially, Kuma had considered using transparent PETG for the production of the joints. However, following an exploratory visit to Caracol, he was struck by the performance and flexibility of TPE – a thermoplastic elastomer which can be used for cushioning, flexible structures, or logistics applications. Impressed by its versatility, he ultimately chose this material as a more suitable alternative for the project.
