100% sustainable & creative

Nobufil is the first Austrian sustainable 3D printing filament manufacturer with its own recycling and in-house filament production. The company is located in Krems an der Donau, Austria.

Would you like to become part of our team and make the world a little bit better with your creativity? Then send us your CV and letter of motivation


quality that is tested

no bullshit - proven quality

It specializes in recycling industrial plastic waste and producing sustainable 3D printer filaments that have the same or better properties than traditional materials. This 3D printing startup was founded in 2022 by Alexander Datzinger and Robert Lielacher, specialists in recycling with over 15 years of experience.

We are proud to be part of an international technological revolution, to bring sustainability to 3D printing and to further develop it nationally and internationally. Our years of experience in plastics recycling and manufacturing granules and products from recycled plastics, combined with a rich technological environment and thorough control, allows us to produce filaments with unique properties and performance that outperforms traditional plastic filaments.

We want to bring our knowledge and experience to the world of 3D printing by offering sustainable alternatives. So you can create and we take care of reducing plastic waste and a negative carbon footprint.

Alexander Datzinger

Alexander, founder and owner of pexopol GmbH, with more than 20 years of experience in plastic processing machines and raw materials, is increasingly focusing on recycled polymers for technical applications. Alexander believes that nobufil's products will become another innovative example of sustainable solutions made in Austria.


Jim van Hazendonk

Jim has over ten years of 3D printing and design experience. Jim's passion for sustainable technologies and creative methods helped us to improve our brand, packaging and product selection while staying true to our main goal of offering high quality sustainable products. Jim believes that reducing our carbon emissions doesn't require us to use inferior materials. It has always been his goal to manufacture high-quality products from resource-saving raw materials.


the production process

With 100% recycled material we create something new for your creativity

We obtain our starting materials from long-standing and reliable suppliers exclusively from the EU, mainly from Austria and neighboring countries. This enables us to ensure a high, consistent product quality and, thanks to the short transport routes, avoid long truck journeys and thus keep CO2 emissions low.

In our processing, all materials go through several tests. This starts with the inspection of the recycling materials upon delivery, through quality controls during production to mechanical tests of test specimens printed from filaments. In this way, we ensure high-quality printing results of constant quality for our customers.

Production of granules

In a further process step, the granulate produced in this way is used to produce high-quality filament with a constant diameter, which is excellent for printing. When developing our materials, we try to take into account the most important requirements that the FFF printing process entails. Our products are constantly tested internally and externally to ensure that they can be easily processed on the most common desktop 3D printers.

The plastic waste is melted on our extrusion systems, mixed with additives to improve the properties, foreign matter is filtered out and finally formed into plastic granulate.
