The work presented here exposes the development and design of a new
machine: the recycled plastic filament winder understood as an innovative DIY tool
that enables and provides new solutions for the recycling and reuse of plastic,
creating customized filaments that can be used in 3D printing, for instance. It is a
cost-effective and sustainable solution that helps reduce waste and environmental
pollution.
The construction of this machine makes possible to create 3D printing filament from
discarded plastic. It can be understood as one more option among the existing
solutions that, in a profitable and sustainable way, contribute to reduce waste and
environmental pollution. Thus, the construction of this winder joins the set of
machines that allow to extend the useful life of plastic materials, trying to prevent
them from ending up in landfills or seas and oceans; in short, to reduce the amount
of 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 plastic
shavings or flakes, which are then fed into an extruder machine, where they are
melted and, through the winder, this molten mass of plastic is transformed into a
thread or filament that can be used in 3D printing. In addition, this winder design
also gives users the opportunity to create customized filament since the color,
texture and thickness of the filament can be controlled.
