Felfil is a DIY filament extruder for 3D printers completely open source, designed and built for domestic use but also for makerspace. It has been tested for extruding PLA and ABS into filament spools, but is also ready to test polymers with higher melting temperature, such as PET.
The purpose of the project is to allow anyone to make custom filament for its 3D printer reciclyng plastic waste, unsuccessful prints, old models, packaging or starting from plastic pellets; keeping an eye to reducing waste but also to save money for users.
Download for free the technical detail of this filament maker.
“An object, or rather a system of objects mutually independent, that allow the realization of filaments for 3D printers starting from recycled material, plastic waste and unsuccessful models. Ready also to be used with industrial pellets, easily and cheaply available on the territory as a result of the recycling of plastic. With the purpose of making the production system based on Felfil totally local. “
With this goal borne our filament maker project, designed with the maker philosophy and developed within the Fablab Turin. Trying to exploit the opportunities of our time, we give new life to unused components; other necessary parts are readily available on local markets or self-producible in a makerspace.
It is a machine that allows you to self-produce the filament commonly used in 3D printers from plastic waste or chopped polymers.
Yes, of course, just insert the plastic extruder already colored or add dye (approximately 3%) to white pellet.
Yes, plastic bottles are produced in PET (polyethylene terephthalate). Our extruder can treat any thermoplastic polymer which has a melting temperature of up to 300 ° C.
However 3D printers capable of printing PET are still in the experimental stage and consequently are not present on the market.
For exaple ABS and PLA. PLA is the most widely used polymer in FDM 3D printers. Be careful, do not mix them, you have to extrude a material at a time.
We decided to release the technical drawings and manuals online totally free of charge, allowing anyone to build or modify their own version, but not to sell it.
Felfil was born as our graduation project, but we think is important to spread it and improve it with the community to make 3D printers more sustainable economically and environmentally.
