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 nature. And to have these two work together to create a new material which could be applicable for any product," explains Klarenbeek.

The possibilities opened up by this material are many, Klarenbeek claims. "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. We could [even] build a house!"
