3D-printed mushroom roots “could be used to build houses”

Dezeen and MINI Frontiers: designer Eric Klarenbeek, who displayed a chair made out of 3D-printed fungus at Dutch Design Week in October, says the technique could be used to create larger, more complex structures.

Klarenbeek‘s Mycelium chair, which takes its name from the extensive threadlike root structure of fungi, combines organic matter with bioplastics to make a light and strong composite material that can be 3D-printed.

Klarenbeek found that fungus grows quickly on straw, so used powdered straw mixed with water and mycelium to make an aggregate that could be 3D-printed.

“We adapted the 3D-printer and invented a way to print straw injected with mycelium. By infusing this mushroom it acts as a kind of glue so that all these straw parts [combine] together and as soon as you dry it you get a kind of cork material, which is all bound together,” says Klarenbeek.

The chair’s exterior is also 3D-printed, but is made from a bioplastic, against which the mycelium root structure grows. Klarenbeek leaves the fungus to spread throughout the 3D-printed structure, reinforcing it in the process.

“Our main purpose was to find a combination between the robot, or the machine, and to have these two work together to create a new material which could be applicable for any product,” explains Klarenbeek.

He claims the material has many possible applications. “It could be a table, or a whole interior, and that’s where it becomes interesting for me. It’s really strong, solid, lightweight and insulating, so we could build a house!”

Dutch Design Week 2013: designer Eric Klarenbeek has 3D-printed a chair using living fungus, which then grows inside the structure to give it strength (+ slideshow)

The chair is the result of a collaboration between Klarenbeek and scientists at the University of Aachen to develop a new way of printing with living organisms. “Our main purpose  was to bring together the machine and nature to create a new material that could be used to make any product,” Klarenbeek told Dezeen.

The result is a new material that, Klarenbeek believes, could be used to make almost anything in future. “It could be a table, a whole interior or even a house,” he said. “We could build a house with it.”

Presented at Dutch Design Week in Eindhoven this weekend, the Mycelium Chair was printed using a mixture of water, powdered straw and mycelium, which is the thread-like part of a fungus that lives underground.

The mycelium grew within the structure, replacing the water and creating a solid but extremely lightweight material. Mushrooms began sprouting on the surface, at which point Klarenbeek dried out the structure to prevent further growth.

“When you dry it out you have the straw kind of glued together by the mushroom,” Klarenbeek said. “You have this strong, solid material that is really lightweight and durable.”

A thin layer of printed bioplastic covers the structure of the chair to contain the growing fungus. Straw was used as a substrate since the fungus used in the project – the yellow oyster mushroom – likes to grow on straw.

“The mushrooms are only a decorative element,” said Klarenbeek. That’s why we shot the photograph with the mushrooms popping out. Our main purpose was to bring together the machine and nature to create a new material that could be used to make any product.

“This chair is really a metaphor for what could be made with this technique of 3D printing a living organism and then have it grow further. It could be a table, a whole interior or even a house. We could build a house with it.”

Here’s some text from Klarenbeek:


Studio Eric Klarenbeek most recent project is the Mycelium Chair, a chair in which 3D printing and growing material are combined. 

Designer Eric Klarenbeek interest is combining materials in unexpected ways. Klarenbeek is exploring ways of making 3D prints of living organisms, such as mycelium, the threadlike network in fungi.

He uses experimental raw materials for printing material: organic substrate for mushroom growing and bioplastics. Working with scientists, Klarenbeek has printed a chair from straw, with a thin coating of bioplastic.

Once it is mature it should be strong enough to support a person. The chair is a metaphor for what can be achieved with materials and production methods.
