100% Recycled 3D Printer Filament – Ultimaker: 3D Printing Story


My name is Jonas Martens,
I’m 30 years old. I studied at the Technical University Delft
to be an engineer/industrial designer and from there we, as a collective of engineers,
started our own business, The Better Future Factory. We really want to make
a difference in the world not just by talking about
what is wrong with the world but by showing how things can be done
differently by working with existing systems. The result is Perpetual Plastic. Plastic is a huge problem worldwide. Only 10 to 12 % of all plastics are being recycled. The rest ends up in the environment
all over the world even in our foods,
it literally ends up everywhere. We don’t believe in fighting an uphill battle,
so we don’t directly want to clean up the seas we want to end continuously putting plastic
into the environment. After that the seas can be cleaned
and will hopefully stay clean. There is an industrial revolution 3.0 happening
as we speak with the invention of 3D printers. By using this new development we want
to start industrial revolution 3,5. We clean up the plastic cup in water and dry it in a tumble dryer. Then we crush it into small pieces. This machine contains a drill, which pushes
the plastic in the right direction. This area is heated to 186° Celsius and melts the plastic to
a density similar to chewing gum. Then it’s pushed through the nozzle
into a tube with a diameter of 3 mm. Through this process and by using a 3D printer we’ve transformed this cup into a plastic ring. It’s a small circular economy on a local scale. These are made of recycled car dashboards. We also use PET bottles. We use specific recycle streams
which are safe and consistent. So the materials we use are chosen consciously. We believe in the local production of useful products to empower people locally. When you make new plastics you need
new raw materials like oil and history has taught us what the effects are. We want everyone to start using
recycled plastic wherever they can because the quality is
exactly the same as new plastic.

  1. English subtitles? Or you could expect all your viewers to be bilingual. You guys should have more subscribers. Make your channel more friendly.

  2. This is neat, well directed, thoroughly thought, but don't mislead people into believing the marketing hype of changing the world.
    I would love to just clean cups, bottles, and jugs, grind them and print with the resulting filament, but your installation is not telling the truth in my opinion.
    Nifty system to clean and dry the cups, smart setup with the chained grinders, but a hand-crank extruder? Surely it's more participative, but how can you expect to get a constant diameter out of it? More like "letting people make something that resembles filaments, yet we use a pre-quality-checked filament inside our printers to make the rings". Otherwise you would be getting clogs all the time, and cannot really afford that in an installation where hundreds of people come to check and see.
    Also on your project's webpage you say you were not able to recycle PET in decent filament, while you say otherwise here.

    I love what you do but would love it even more if you were more transparent. For example, sharing your method to actually be able to use, in production, filament in a 3d printer which has been produced from waste. Suggesting where to buy shredders at a decent price, how your extruders are actually made (not the hand-crank one ^_^), how's your cleaning-drying process actually organized to make it cost- and time-effective; like this is now, it appears to me your main revenue and interest is showing cool things at events and being compensated for it (not that it isn't still a great way to constructively entertain people!), and selling your (still very cool by the way) Refil filament which I'm sure you produce with much a more complicated process than any DIY extrusion machine.

  3. oh no, that's not the way you do it. You should be recycling the plastic cups into filament and print back out well, plastic cups
