4-Color Self-Portrait by br3ttb
Not only is br3ttb an OpenSCAD Challenge Imaginary Prize Winner, but he’s also doing some crazy amazing stuff by printing in FOUR colors. Similar to the printing processes of old, br3ttb set down one color at a time on top of another to form a four-color picture, using just one extruder. The result is a very lightly textured and posterized version of br3ttb’s own portrait. In the true spirit of Thingiverse, he has shared lots of information about his software toolpath and design process so you can try it out yourself.
I’m also reminded of a recent Thingiverse contribution from RichRap where he achieved a similar effect by cutting and joining different colored filaments and then printing a model that would reveal different colors at different heights.
I suppose if you had an apparatus that could select, cut, join, and feed filaments in conjunction with a LOT of custom firmware and GCode, you could print in 8 bit color!
I needed a new profile image. While I'm proud of the project that lead to my former "TV face" image, it didn't really say "Thingiverse"
Having just successfully created a 3 color bottle opener, I knew the time for a multi-color portrait had come.
This is my first attempt at mashing colors together on the same layer like this. I'm really happy with the results. Hopefully others will take this technique and run with it. Turns out you don't need dual extruders to make a multi-colored part!

This was an experiment using some great coloured Faberdashery PLA filament.
It was not just designed to look pretty as I added lots of sections for filament bridging and thin layers for colour change. Skeinforge finds bridging on curves hard as it decided on an angle for the direction of bridge and does the whole section the same angle, so at points along the curve filament is going straight into the gap, this makes it a hard test especially when done at high speed, that’s why you can see a few gaps and dips in the model surface. I could make it look much better with a different Rainbow design but this was testing how the filament would perform on my Prusa Mendel ‘Bling’ machine.

I was thinking it would be fun to do repros of houses in your neighborhood.
