Adafruit Proto-Pasta - 1.75mm Conductive PLA Filament
Share this Product
Sorry! We had to get that out of our system. Proto-pasta is conductive PLA filament from ProtoPlant. It's a great way to make something with an LED, touch sensor, or some other electronics through your 3D printer. The filament is great for low-voltage circuitry. A great way to think of it is that anything you can run through a 1K resistor should work witht his filament. Not all 3D printers can use flexible filament, so make sure your 3D printer is comptaible before purchasing.
This is 1.75mm filament and is made in the USA by Proto-Pasta. Check out the proto-pasta site here for more information!
