3D Printing Filament Made from Coffee Waste

Ever wondered if there’s a better use for your morning coffee grounds than tossing them in the trash? While most of us compost or discard them, a surprising new application has emerged: turning coffee waste into a functional material for 3D printing.

Yes—coffee waste can be processed into a 3D printer filament. A collaboration between 3Dom USA and C2renew has resulted in Wound Up, a PLA-based 3D printing filament made from recycled coffee material, priced at $49 for a 2.2-pound spool (approximately $314 per kilogram).

What Is Wound Up Filament?

Wound Up is a 3D printing filament created from coffee waste. It is not pure coffee, but a biocomposite material that includes coffee byproducts blended with PLA (polylactic acid), a common biodegradable plastic used in 3D printing. The result is a filament that prints similarly to standard PLA but with a rich brown color and natural coffee-like texture.

How It’s Made

The material is produced through a partnership between 3Dom USA and C2renew, a company specializing in bio-composites. They take leftover coffee material—likely spent grounds or other byproducts—and combine it with PLA to create a filament suitable for most FDM (fused deposition modeling) 3D printers that accept standard PLA. The exact coffee content or processing method isn’t disclosed, but the filament retains enough of the coffee’s natural qualities to give it a distinct appearance and smell.

What Can You Print With It?

Because it’s PLA-based and prints similarly to regular PLA, you can print all the usual objects: gears, enclosures, figurines, and more. But because of its unique aesthetic, it lends itself especially well to coffee-themed projects. 3Dom USA suggests printing items like coffee cups, molecular models of caffeine, or cone-shaped coffee filter holders. The company has also printed sample objects including a boat, a cat, and a cup—none of which, presumably, are edible.

Packaging and Sustainability

The creators of Wound Up have extended their sustainability efforts to the packaging. The spools are made from plant-based materials, reducing the overall environmental footprint. This aligns with the filament’s eco-conscious origins, turning what was once waste into a functional and aesthetically unique product for makers and designers.

Frequently Asked Questions

What is Wound Up 3D printing filament made from?

Wound Up is made from a combination of coffee waste material and PLA (polylactic acid). It is not 100% coffee, but a biocomposite that gives it a brown color and coffee-like scent while maintaining print characteristics similar to standard PLA.

How much does Wound Up filament cost?

Wound Up filament is sold for $49 per 2.2-pound spool, which equates to roughly $314 per kilogram.

Can I use Wound Up in any 3D printer?

Wound Up is designed to work with most FDM 3D printers that support standard PLA filament. You don’t need a special printer to use it.

What does Wound Up filament look and smell like?

The filament has a rich brown color and a natural coffee-like texture. It may also have a slight coffee aroma, adding to its aesthetic appeal for coffee-themed prints.

Is Wound Up environmentally friendly?

Yes. It is made from recycled coffee waste and PLA, a biodegradable plastic. Even the spools are made from plant-based materials, further reducing its environmental impact.

What kinds of things can I print with Wound Up?

You can print all the same objects as with standard PLA, such as tools, enclosures, and decorative items. It’s especially suited for coffee-related designs like cups, filters, or caffeine molecules.
