Even with ABS, PLA, Nylon, HIPS, and a bunch of Taulman filaments, the world of 3D printers is missing out on a great supply of spools of plastic filament. Plastic welding rod is available from just about every plastics supplier, and in more variety than even the most well-stocked filament web shop.
This Kickstarter hopes to put all those exotic plastic welding rods to good use. Instead of being designed to only use 1.75 and 3mm filaments, this guy will extrude welding rods up to 4.76mm in diameter. This opens the door for 3D printed objects made out of PDPF, PVC, Polypropylene, Polyethylene and other high molecular weight plastics.
Because these welding rods are much bigger than the usual plastic filament, this extruder also has the option for a very beefy NEMA 23 motor. It’s the perfect solution if you’re planning on building a homebrew ludicrous-sized printer, or you just to show off just how awesome you are.
