We recycle plastic waste into high quality 3D printing filament.
Request a quote for our recycled filament
For the past two years, we have been developing a recycling process to make 3D printing filament from plastic waste. Follow us on social media to see the current state of our projekt at any time.
We guarantee tolerances under +-0.04mm
Our filament is made from 100% plastic waste that we shred and recycle. Read more
We ship exclusively via DHL with tracking.
We produce all our coils using an injection moulding process with recycled bottle tops.
If requested, we offer material tests with our products. For this purpose, we shred or pelletise a sample of approx. 5 to 10 kg and produce new filament from it, which we then test with various 3D printers.
We also write a detailed report on the entire recycling process with all process details as well as corresponding video and photo material.
For sustainable use, we produce all coils from old bottle caps. Glass bottles are rinsed out and reused in Germany - but the lids are disposed of because of the broken safety ring. We have made it our task to find a better solution for the lids. With our own machine we sort them by color and then process them into high quality recyclates. We can then use these, for example, for our coils.

In terms of mechanical properties, HIPS is one of the top materials and has a much higher impact strength than PLA, for example.
Objects printed with HIPS have very smooth surfaces, which give the parts a much higher quality finish.
When printing ABS, a rather unpleasant smell occurs over time, this is reduced to a minimum with HIPS. Still, it is recommended to ventilate.
Conventional ABS quickly develops a "yellow tint" after being exposed to UV light for a longer period of time. HIPS however is UV resistant.
HIPS can withstand temperatures of up to 85°C, making it one of the most temperature-resistant materials in 3D printing.
HIPS is also ideal for underwater applications or pipe connections.

Private customers:
We do not currently sell filaments for private customers because we cannot compete with other manufacturers in terms of price. In the long term, our goal is to reduce costs through production optimization in the recycling process and a fully automated online store to such an extent that series production is economical for us.
Business customers:
For business customers, we offer our PETG filaments for purchases of at least 10 KG. Currently, we also used our filament extrusion lines in the laboratory for feasibility studies and material analysis for companies and institutes. We produce filaments from special engineering plastics and compounds. Just contact us at info@qitech.de.
Sign up and you will be notified as soon as sales for private customers start.
We also provide weekly insights into our production on social media

We recycle production waste from large factories here in Rhineland-Palatinate as material for our filament.
In many manufacturing processes, for example, sprue channels (small plastic leftovers) are produced, which we collect and recycle. We also process rejects from the production of skirting boards.
For the production of the master coils we use bottle tops from normal plastic bottles that we collect from schools, offices etc. In the future, we also want to recycle shampoo bottles from barbers into filament.
First, we grind the plastic waste into fine granules. Then we dry it and fill it into our self-built extruder (a plastic melter). There, the plastic melts at about a temperature of 200 °C and is pressed through a nozzle. The filament that comes out of the nozzle is then cooled and perfectly wound with our JARVIS Winder.
Yes, we produce all our filament coils in our own production hall in Darmstadt.
