PETFusion 2.0: Recycling PET bottles for 3D printing on Kickstarter

With the PETFusion 2.0, a current crowdfunding campaign on Kickstarter offers an interesting solution for recycling PET bottles. However, instead of selling the machine itself, backers receive the STL files with which they can produce the PETFusion 2.0 using their own 3D printer. This is primarily aimed at tech-savvy users who already have experience with 3D printing and are interested in sustainable alternatives for filament production.

The PETFusion 2.0 enables PET bottles to be recycled into 3D print filament. The design helps to cut the bottles into strips. The material is then processed into filament using an extrusion nozzle with a diameter of 1.75 millimetres. During the production process, the filament passes through an ink-based coloring station that gives the material color. The machine also contains a filament welder that seamlessly joins shorter pieces of filament. This allows larger spools to be produced.

The PETFusion 2.0 combines several functions in one compact machine: bottle cutting, filament extrusion, spooling and welding. Supporters of the campaign receive the print files for 39 US dollars, which also include a list of the required non-printable components and building instructions. For higher contributions, there is also a commercial license that allows you to manufacture and sell the machine yourself.

There are also similar open source projects with PETamentor2 SS. The files can be downloaded free of charge from Thingiverse. There are comparable projects at Printables.

PETFusion 2.0 has already reached its funding target of 1800 US dollars and currently stands at over 10,500 euros.
