ZHA and Nagami collaborate on the Echo Chair, a 3D‑printed seat made from recycled PETG that blends parametric design with sustainable manufacturing.
The Echo Chair, a striking collaboration between ZHA and Nagami, showcases how 3D‑printing can be both sophisticated and sustainable, using recycled PETG filament to create a sleek, parametric seat.
Design Philosophy and Materials
ZHA’s design team employed advanced parametric modeling to generate an organic lattice that optimises strength while minimising material waste. The chair’s structure is printed from 100% recycled PETG, a durable thermoplastic derived from post‑consumer plastic bottles, underscoring the project’s eco‑centric ethos.
The resulting form balances a lightweight aesthetic with robust support, demonstrating how digital fabrication can move beyond prototype novelty into functional, high‑end furniture.
Manufacturing Process
Each Echo Chair is produced on a large‑format FDM printer, with the lattice geometry sliced into precise toolpaths that reduce print time and filament usage. The recycled PETG filament offers a glossy finish and a high degree of impact resistance, eliminating the need for post‑processing or additional coatings.
The chairs are printed in a single, continuous build, which reduces assembly steps and further cuts down on carbon emissions associated with transportation of multiple components.
Aesthetic Impact and Market Reception
Critics have praised the Echo Chair for its elegant, almost sculptural presence, noting that the seamless integration of form and function makes it a standout piece in contemporary interiors.
- Sleek, organic silhouette
- Eco‑friendly recycled PETG construction
- Parametric lattice optimised for strength
- Single‑piece 3D‑printed manufacturing
Early adopters in design studios and boutique hotels report that the chair not only elevates the visual language of a space but also aligns with growing client demands for sustainable luxury.
“The Echo Chair proves that 3D‑printing can deliver both aesthetic refinement and responsible material sourcing,” a design analyst noted.
As 3D‑printing technology continues to mature, collaborations like ZHA × Nagami set a precedent for how designers can push the medium toward mainstream, environmentally conscious production.
