Recycled plastic prints house in twelve hours in Melbourne

Published on May 16, 2026 | Translated from Spanish

Australian company Contour3D has completed the first 3D-printed plastic home in the southern hemisphere, located in Melbourne. With 55 square meters, the structure was materialized in just 12 hours of continuous printing, using recycled polymers from industrial and household waste. The process reduces costs and time compared to traditional construction, offering a sustainable and modular alternative for different climates and terrains.

3D-printed house made of recycled plastic in Melbourne, built in 12 hours, sustainable and modular.

Recycled polymers and large-format additive manufacturing 🏗️

The large-format printer uses an additive manufacturing process that combines recycled plastics with a continuous extrusion system. The house includes integrated thermal insulation and modular design, allowing it to adapt to different environmental conditions. By using materials from industrial and household waste, Contour3D manages to reduce the carbon footprint of construction. The structure was erected in a single day, demonstrating that speed is not at odds with energy efficiency or structural strength.

The Lego house for adults that doesn't touch the ground 😂

The funniest thing is that this plastic house is printed in 12 hours, but surely the municipal procedures to approve the construction take twice as long. And although the modular design promises to adapt to any climate, we'll have to see what happens when the neighbor down the street decides to have a barbecue very close to the recycled polymer walls. At least, if it melts, they can recycle it again and start over.
