Additive manufacturing is great, right?
Remember the difference between additive vs subtractive manufacturing?
It's great, but it does generate waste in the form of rafts, supports, and failed prints.
We can take this waste plastic and shred it in a heavy duty paper shredder. This will create small, easily melted pellets that we can put in a hopper
The hopper would feed a heating element which would raise the filament back to its liquid state, then be re-extruded through a 1.75mm nozzle.
The resulting filament can then be spooled for re-use. Here's a page
that goes through the process.
Good. Now we can purchase one of these pre-assembled and ready to go, but they are costly! Check out the ProtoCycler+
There are also DIY Kits and projects out there. Check out the Filastruder Kit
for $310.Okay, your job is this!
Go out and research all of the different options for Filament Recycling for 3D printing. I prefer a mechanical, in-house, solution where we can create our own, but if you find a better way, please present it! For example, there are companies you can ship your waste filament, and trade it for spools they sell at a discounted price.
After your research, reply to this post with a list of your three best options. Please also list pros and cons of each of your choices, along with a rough cost of the completed project.
