Printed on a Prusa i3 MK3 with MMU2. To be honest, the multimaterial upgrade for the MK3 needs more development and better guides for troubleshooting, although both guides and firmware have improved recently. Still, this was my third successful print of this penguin. Original sized, with wipe-to-infill in all colors except the white parts, and with extra purging for white (I still need more, I see...). Took about 10h. I hope to see more developments to the MMU2, as it still lacks the consistency of the MK3 and is the reason I had only a 20% success rate of this print in multi color.
White, Black, Orange
If possible (which it is with Slic3r PE), only allow supports under the wings. Supports aren't needed anywhere else.
