It is acost-effective and sustainable solution that helps reduce waste and environmentalpollution.The construction of this machine makes possible to create 3D printing filament fromdiscarded plastic. It can be understood as one more option among the existingsolutions that, in a profitable and sustainable way, contribute to reduce waste andenvironmental pollution. Thus, the construction of this winder joins the set ofmachines that allow to extend the useful life of plastic materials, trying to preventthem from ending up in landfills or seas and oceans; in short, to reduce the amountof plastic waste that every year pollute the ecosystem and the environment.The winder works by taking plastic from disposed containers such as bottles, caps,jerry cans, etc. These containers need to be previously shredded into small plasticshavings or flakes, which are then fed into an extruder machine, where they aremelted and, through the winder, this molten mass of plastic is transformed into athread or filament that can be used in 3D printing. In addition, this winder designalso gives users the opportunity to create customized filament since the color,texture and thickness of the filament can be controlled.
