Printing Filament?

[LesHall 95]

OK so this idea is rather silly, but it might be worth trying. I would like to 3D print my own filament. When you stop laughing I will explain.

The idea is to print one filament on top of the other or combine more than two filaments into one striped small coil. This is a way to make some really interesting filaments. I'd begin by printing two colors and seeing if they mix in the hot end to make a third color. For example I have no orange filament for printing a pumpkin. I do however have red and yellow. So I print part red and on top of that yellow, and when I print with it I get orange!?!

When this has been tested working, how about mixing filaments with different properties. Like for example how about PLA based magnetic iron from Proto-Pasta with PLA based conductive filament? Maybe the Proto-pasta conductive filament for a 30x higher resistance, or Functionalize graphene (similar to Black Magic graphene) for 30x lower resistance. If you have a wire that also has magnetic properties, what does that do? Does it make something useful or interesting?

I'm sure you can think of other cool mixes. So: bright idea or stoopid idea? You tell me!

p.s. can also add fillers this way, such as cupric oxide to make a semiconductor maybe?
