we're gonna see how to recycle milk jugs and soda caps into filament
by melting them with the heat of a cheap soldering iron
- one empty CO2 cartidge
- one soldering iron
- insulating material (ex rockwool)
- one piston that fits inside the CO2 cartidge
- a vice or some clamps

Step 1: Manual Bottle Extruder With a Solder Iron
i wanted to know if i could recycle HDPE (milk bottle) at home so i made a ghetto hot end with a solder iron, clamped a CO2 cartidge on it it finaly melt and i got 5 mm of rough and strong filament by pressing with a piston tool i need a mechanical process to get a regular filament i can make pellets again with it for the moment :) i'll also need more heat to make the hdpe more fluid and make the extrusion smoother and maybe some insulation on the hot end.
Step 2: DIY HDPE EXTRUDER (from the Ghetto)
recycle your milk jugs and many more things into 3D printable filament
i've hacked a solder iron to make my heating source,60W !!! way more powerfull than my first attempt my auger is made of a 15 mm wood drill bit, my electric drill and a vice i made about 3 meters of filament with 1.5 grinded bottles and many losses the non regular diameter goes from 2 to 4 mm.
Step 3: Step 3 : Rewind the Heating Filament and Add Motor
i rewound the filament directly on the metal tube to increase the heating
it works , a bit too much i'll have to moderate it
i also added a support structure made of wood and a drill motor to run the drill bit anticlockwise
