After nine months of development, German company twoBEars has launched bioFila, a new biodegradable filament designed for 3D printing.

The material is based on lignin, a complex polymer of aromatic alcohols known as monolignols. It is most commonly derived from wood, and is an integral part of the secondary cell walls of plants and some algae.

The bioFila is 100% biodegradable and made from renewable raw-materials, so when you throw it in a landfill or soil it will ultimately break down. What makes the bioFila different from the existing materials is its hardness and charpy values, which are much higher than the others. These high-strength material offers new possibilities for the design of parts, which requires higher resistance against stress and pressure.

The bioFila has currently two kinds of biopolymer blends optimized for 3D printing: bioFila silk and bioFila linen.

The bioFila silk is a blend of different biopolymers with a silky look. With this material you can realize an impressive, noble look of your products, for example vases or lamps.

Technical Data:

  • Nozzle: 0.5mm
  • Layer thickness: 0.45mm
  • Speed: 20mm/s
  • Extruder temperature: 165 - 200°C / 329-392°F
  • Hot-bed temperature: 90°C / 194°F

Technical data:

  • Nozzle: 0.5mm
  • Layer thickness: 0.45mm
  • Speed: 20mm/s
  • Extruder temperature: 220 - 240°C / 428-464°C
  • Hot-bed temperature: 65°C / 149°C

The bioFila product line is priced at 49.90€ / 750g (VAT inclusive) and will be available in April 2014. You can find more info or pre-order them here on twoBEers' site.

Currently the company is also developing the next series of bioFila line, including BioFila Terra, BioFila Chlorophyll, BioFila Vulcano.

Hello! I am very interested in knowing more the characteristics of the bio fila. I am currently testing new materials for jewelry and I would like to know more how can I use this material. Also I would like to know more about the 3d printing process with this material. I appreciate your comments and information.

Can you please add attribution for the models? The manufacturer seems to have forgotten to mention he did not get my permission to use these files to promote their filament.

@Stef : the reasons why our material is only now ready to be sold were those difficulties with the diameter. We needed 3 months and more to improve that - now it's done. The free sample you got was not ok, but it was sensed to help us to improve the new material. We hoped for helpful critics, but ... :-/ No critics - no help - for sure it was the wrong way, I agree. The price is high ? Not really if you consider that it's really a NEW material (not PLA + some filling stuff), the raw materials are noble (but not so easy to treat) and we do not sell the quantities like PLA f.ex. The moment we will do so, the price can become "nicer". That is our target !!! :-)

Got some for testing, had diameter changes of +- o,5mm... needs to be improved.. especially for that price!

At half that price I would use it.

Wow, looks sweet! The price is high and this filament requires a heated bed, but I guess it will find it's customers for sure :)
