# In-Situ Circular Furniture PORTAL by Decibel Prints Furniture Live to Demonstrate Circular Design By Amy Duong | Published 2025-07-18 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/portal-by-decibel References: [decibelmade](https://www.decibelmade.com/portal) & [design-milk](https://design-milk.com/portal-celebrates-circular-design-by-printing-furniture-in-situ/)  PORTAL by Decibel prints furniture live to demonstrate [circular design](https://www.trendhunter.com/trends/Circular-pavilion-design) with in‑situ fabrication. Hosted by the brand in Milan’s former SNIA factory, the installation features a colossal 15‑foot industrial robotic arm that [3D‑prints chairs](https://www.trendhunter.com/trends/echo-chair) layer by layer, using [recycled materials](https://www.trendhunter.com/trends/bultan-chair). Each day concludes with a freshly printed chair, highlighting the process of creation unfolding amidst natural decay and sunlight filtered through broken walls. The pieces are crafted by designers like Karim Rashid, Charles Birshaw, and Noknok. Portal explores material lifecycle and circularity, placing production directly within the exhibition space. The use of recycled plastic and live printing encourages viewers to consider infrastructure, scalability, and the future of sustainable manufacturing. As Decibel co-founder Adam Hecht states, the project seeks to break barriers between concept and creation, fostering a collaborative ecosystem for designers, recyclers, manufacturers, and consumers Image Credit: Decibel ## Trend Insights (Trend Hunter) - Score: 2.7/10 - Popularity: 18% | Activity: 19% | Freshness: 44% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: North America, South America, Europe, Asia, Africa ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) ## Key Themes ### What Makes This Trend Stand Out - **In-situ Creation:** The shift towards in-situ creation offers a unique approach that removes traditional boundaries between design and production, fostering immediate consumer engagement and reducing logistics costs. - **Circular Manufacturing:** Circular manufacturing utilizes recycled materials in real-time production processes, reducing waste and promoting sustainability in the design industry. - **Robotic 3D Printing:** The implementation of robotic 3D printing in furniture manufacturing enables innovative design possibilities while minimizing labor costs and enhancing precision. ### Sectors Adopting This - **Eco-friendly Furniture:** The eco-friendly furniture industry can benefit from adopting circular design principles that leverage recycled materials and sustainable production methods. - **Additive Manufacturing:** Additive manufacturing represents a disruptive force in traditional production models by enabling customizable, on-demand creation using advanced 3D printing technologies. - **Sustainable Design:** Sustainable design emerges as a critical industry segment where designer and consumer collaboration can redefine product life cycles and environmental impact. ## Related on Trend Hunter - [3d-Printed Rubble Furniture](https://www.trendhunter.com/trends/inorganic-growth.md) - [3D-Printed Recycled Misprint Chairs](https://www.trendhunter.com/trends/the-new-raw-studio.md) - [Sustainable 3D-Printed Chairs](https://www.trendhunter.com/trends/wood-loop-lounge-chair.md) - [Recycled Material Furniture](https://www.trendhunter.com/trends/project-materia.md) - [Playful Outdoor Seating](https://www.trendhunter.com/trends/the-new-raw-1.md) - [3D-Printed Wooden Furniture Series](https://www.trendhunter.com/trends/econitwood.md) - [3d Printed Lighting Sets](https://www.trendhunter.com/trends/tierra-mar-y-aire.md) - [3d-Printed Brutalist Chaisr](https://www.trendhunter.com/trends/object-01.md) - [3D-Printed Recycled Material Furniture](https://www.trendhunter.com/trends/loom-furniture-collection.md)
