Coloring filament with Sharpies

Post by jsc » Tue May 13, 2014 7:24 pm

This has been discussed briefly before, but here's a write up on it: http://hackaday.com/2014/05/08/coloring ... -sharpies/

Because the filament is being fed through the body of the Sharpie, this isn't as useful for color changes. Perhaps a variant of one of those printed filament wipers I've seen around would work, snap on, but instead of wipes you would have dye saturated cotton balls.

Does that mean that it's possible to inject pigment directly into the melted filament somewhere inside the nozzle, to get full color printing from only one extruder? Has anybody ever tried that?

posted instructions several years ago :)

A little history...how this happened was that the very early extruders (mid 2009) rarely worked...so we'd mark filament to see if it was moving. one time i used a pink sharpie to mark it and then noticed a pink band in the print...
