3D Printing Wood-Based Material for Concrete Casting

This video presents a novel method — developed by researchers at Dart Laboratory — of coupling robotic 3D printing of wood-based material with incremental set-on-demand concrete casting to create zero-waste freeform concrete structures. The team has also developed a wood-based material mix that is fully biodegradable and recyclable.

“We have made a recyclable, all natural biomaterial which is made out of sawdust. Other sawdust-based solutions are using other petroleum-based polymers—we use biopolymers which are completely decomposable,” said Muhammad Dayyem Khan , researcher at the DART laboratory. “And the biggest thing is it’s very easy to recycle and reuse.”
