[RichRap] came up with an interesting solution to this problem by having three filament extruders feed into a single hot end, allowing him to change and … Read the rest

The new developments are a continuation of [Adrian]‘s experiments with a mixer extruder that squirts four different colored filaments out of the same nozzle.

After drooling over the Makerbot dual-head extruder, [Brett] decided to get off his duff and make a proper multi-color print.
[Brett] has been making a few bottle openers for friends and has been successfully experimenting with switching filaments in the middle of a print. For his “Saturday Killer” bottle opener, he decided to push multicolored prints to the limit. … Read the rest
