3D printed wood made by recycling wood industry by-products like sawdust


Even though 3D printing naturally produces less waste than other manufacturing processes, it is sadly normal that 3D printed creations are made of materials derived from plastic. So to combat this, a startup called Forust 3D prints wood products – and its raw material is recycled sawdust and other by-products from the wood industry that would otherwise be considered waste. .

“Forust technology allows us to take something that was previously wood waste and re-materialize it into things of exquisite and useful beauty,” William McDonough, a world-renowned sustainable architect (who is not involved in Forust, but which supports the technology.) said in a statement sent to Green questions.

“By allowing millions of trees to remain in place in their forests, Forust is launching highly evolved technology for the circular technosphere that supports and celebrates the stewardship of the natural, regenerative and diverse biosphere, making it not only smart, but also wise ”. McDonough added.

Here’s how Forust’s 3D printing process works, according to press material shared with Green questions.

Forust begins with two by-products of the wood industry: wood flour (a fine filtered sawdust) and lignin (a natural polymer found in the cell walls of woody plants). Forust then uses advanced CAD 3D printing software, proprietary materials, and Desktop Metal’s binder-jet mass production platforms to recycle wood industry waste into “isotropic, high-grade lumber pieces.” resistance and durable ”.

Specifically, Forust spreads layers of specially treated sawdust, which are then treated with a biodegradable, non-toxic binder to turn them into wood. Then the digital grain is printed on each layer of the wood before traditional wood treatments are applied, such as sanding, staining and staining.

The parts can then be used to make furniture (including chairs and cabinet doors), luxury interior parts (such as gearshifts and other parts for yachts and houses), various consumer products (such as fruit bowls and flower pots), and even in architecture. .

“With the Forust process, we recycle sawdust waste and turn it into beautiful products that can be used for a number of applications – interior design, buildings, furniture, architectural products and consumer goods for the home,” explains Jeffery Green questions exclusively.

“The inspiration for Forust was to start with sawdust and end with forests,” Jeffery added. “Our process is based on extensive research carried out over the past decade in the field of hardwood lumber, resulting in complex and elegant finished structures.

Forust says its process can mimic almost any grain of wood (including a single grain-less wood), adding that its 3D printed products are “digitally rematerialized wood, with a grain that flows all over the room and can be sanded.” To be touched. These products are nothing like particle board, an affordable wood alternative made by pressing down wood chips with a synthetic binder (and commonly seen in places like IKEA).

“Our finished pieces are indistinguishable from the traditionally crafted wood products you find in a store,” Jeffery said. “The additive manufacturing process literally becomes invisible.”

If you want to get your hands on a 3D printed wooden product, Forust has launched a collection of products made with several independent designers and brands. Products are now available for purchase from the Forust website, including a line of wooden vases and bowls designed by Yves Béhar from fuseproject.
