Would love to see how you did it! Looks great!

Wow! Could you post a video to show the hot-swapping filament?

Crazy amazing!How is ur machine now?

These prints are incredible !! Love the abstract look !

Now I want to try again to fill a bowden with many little piece of color :)

(I hadn't seen this thing at the time and discovered it with the latest Richrap post)

Absolutely fantastic patterns, love the play with transparency!

This is seriously inspiring! Thank you so much for sharing this!

just. effing. amazing. I've done some multi-color stuff that I thought was pretty epic, by breaking my designs into multiple prints and printing them separately. based on the amount of waste plastic between color swaps I never would have expected that you could get such pronounced color definition.

hats off to you! I hate you! in the best possible way. :)

Thank you for the kind words. I hate you too! lolz.

I like your project in OpenSCAD. Thanks for the links. Having more info on multicolor techniques in one place should help stimulate more ideas.

That is really stunning, very nice Job !!!!! 8-) Love it, Love it, Love it !

Sir, I am honored! Your work inspired me to get my machine running in the first place.

I'm excited to see what's next!

Gorgeous effect. Brilliant!

Awesome proof of concept. How long until someone automates it? =)

Indeed! There was a machine on Kickstarter that woulda done it, but sadly wasn't funded : http://www.kickstarter.com/projects/1756440631/indymaker-color-3d-printerhttp://www.kickstarter.com/pro... . I'd like to see how that mahine does the cut-n-follow.

Also the "raise the Z" effect could be added manually to the gcode, or integrated into the slicing software. Please!?!?!? 8-)

It probably didn't get funded because it didn't have a goofy intro video.

 or, probably, because the printer prints incredibly slow, and look sooo much like makerbots...

Umm this is absolutely amazing! I can't believe how awesome you made these look by switching out filament. How could you have been so accurate regarding the perfect time to start feeding the next color? Since there is already melted filament in the extruder"tube," I mean. Really cool stuff! 8-) =-O

Awesome. Thanks! :-D

Accuracy of color switches isn't really required. I just picked colors that blend well and kinda time it. I get three one inch colors loaded in top before they come out, but extruder/ hottip length can vary. An inch of 3mm is about one square inch of surface with 0.30mm layers.
