Milk Jug Printer

Combining 3D Printing with Recycling

Similar projects worth following
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).

Enjoy this project?

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.

Here's one where some team used cut-and-melted milk jugs to print a boat!

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
