3D printer filament maker

Create 3D printing filament from PET flakes.
Bottle → Flakes → FILAMENT → 3D Printing

Similar projects worth following
By creating our own unique designed extruder, we are scheduled to complete our first batch of 100% recycle filament by July 2018. Our unique system is purposely designed so that it can be easily reproduced. All parts are printed from b-PET, 100% recycled PET. You can contact us at petmatzu@gmail.com or at may.corentin@yahoo.fr

    On the 23rd of june we are showing our filament maker on PETMAT's stand.
    It's the occasion to discuss and exchange about this project.

    SATURDAY

    Before the offcial oppening

    We prepared the stand.
    We met fas83 who also work on this kind of machine.

    During the morning
    People demonstrated an interest to our machine and ask us if it's possible to buy our filament. For now we buy b-pet filament from Argentina.

    SUNDAY

    We did get other contacts. We are glady suprised to met a lot of people interested in this project.

    We think about organize a conference with the people we met!

Well done! Hope your ideas spread and become available widely. In a related vein I read about this project in the Netherlands to "overfish" the canals: https://plasticwhale.com/
