I came across a blog from Rich @ richrap.com, who by using nylon and some rit fabric dyes was able to make some very useful vases and object with his 3d printer. I also came across this object on thingiverse which allows you to color white or clear (or really any filament) using sharpie markers:
So I ended up picking up some sharpie markers from amazon and decide to have a go a colorizing my filaments. Here is the video below: (bonus stay to the end and see the polymakr filaments as well as a test of the uv sensitive filaments with a blue laser! :D)
I saw this little project on thingiverse today and figured I should include the object, its for testing out nylon and rit dyes vs how many hours you leave the samples in the dye. Very useful to have samples for what can be done and what effects you're capable of when planning new projects or objects!
