A few people are starting to look at multi-part or multi-colour printing using BfB machines with multiple print heads and BfB Axon2. It is a little confusing and preparing the files to print can be difficult.
I have prepared a screencast showing how this can be done with the free version of Netfabb. I’ve posted it on Youtube, and you can also have a look here ..
Hope it helps a little…. happy multi-part printing!
