Portuguese student creates a 100% biodegradable cork filament for 3D printing

Now it is possible to make 100 percent biodegradable 3D prints with a cork-based material thanks to the student Tatiana Antunes. She developed this method at the University of Aveiro (UA) for her Master’s thesis in Materials Engineering. Her work addressed the real problem of cork waste resulting from the manufacture of stoppers.

The cork filament is a totally innovative and ecological solution

Certainly, most filaments currently in the market are not friends of the environment since these contain plastic ingredients.

In contrast, cork filament can be an excelent alternative to average FDM materials and also give the touch, smell and color to printed objects that only cork could provide. Very surely, we could use it instead of the synthetic filaments available in the market.

So, how did it become possible to produce a 3D printing material from cork?

Tatiana reveals that it is a composite filament. It was developed using a biodegradable plastic matrix and incorporating cork particles that are part of a residue resulting from the process of manufacturing caps.

The filament has brown tones, a slightly rough touch and, during the printing process, emits a slight smell of cork.

“We have, thus, a filament for 3D printing, with personality and friend of the environment. It can be used for the most diverse prints, because it allows the printing of objects with excellent aesthetics and quality, with an associated characteristic color”. Says Tatiana Antunes.
