I saw a project where someone was melting down milk-jugs and used the plastic to make a hammer.
I also own a 3D Printer that uses filament.
I'm curious if we could design something to melt down recyclable plastics in the home to use with low-resolution 3D Printing.
I don't think that we need or want to turn milk jugs into filament, so I'm curious if we can combine this with a chocolate printer someone made where the chocolate is kept in syringes.
This way, the milk jugs would get melted in a vat, transferred to a heated syringe, and then forced through a nozzle (which itself is on a 3D Rig).
It is no good idea to keep the polymer hot for an extended period of time. It will degrade. So as tempting it is to omit the filament making process, it is not a good idea to keep all that plastic at its melting temperature.
I was thinking of making plastic, to be made into filament. something like (but I do not have the cash to do this. I think this could be even be a cheaper way to make filaments :-
there are a number of projects out already for this. Search for 'DIY filament extruder' to get a good sample. That being said, there is always room for improvement so keep us posted if you build one and any improvements you make. Good luck
