Chris Olah, a fellow RepRap hacker from Hacklab.to, has been experimenting with multi-colored prints on our Makerbot by loading differently colored ABS segments into the extruder. So far this has resulted in at least one extruder burn and a couple of really nice parts.

Nice! That's really smooth transition.
ReplyDeleteA friend of mine did this on his Ultimaker: http://picasaweb.google.com/lh/photo/xU6IxAtnIYXv-x5Sp0WcOLg43EqgxEYno3v9myjRzRw?feat=directlink
The bowden cable allows you to preload it and it will come out first-in-first-out! So you won't have to pay attention or melt the pieces together.
That's awesome! Actually, everything I've seen about the ultimaker looks awesome, but that's particularly so!
ReplyDeleteI imagine if the object was smaller, you'd see more transition. There also seems to be an element of luck involved: sometimes more of the older colour stays buffered in the extruder, others less.
