Answered Which 3D Printer with 3 nozzle/colors/material

Don't really know of any. Dual extrusion is hard enough to pull off.

 

Three would be insane. If you have ever used a multiple extruder printer you would understand the issues with slicing and modeling that are there for that sort of printer (each nozzle essentially has a slice).. Two is complicated enough. I can't imagine 3.

 

Pretty sure I'd crawl up in a ball and die lol

 

You can use special nozzles for multiple colors and the like on a single extruder.
Multiple extruders are really for multiple materials (different temperatures and print speeds, etc)

Multiple extrusion for color is silly (paint -- easy). Multiple extrusion for multiple material is really cool, but darned hard to get right.
Without independently movable extruders it is hard. Heck even with that it is a slicing headache. Each print head has a slice to deal with and where they overlap? DANGER Will Robinson!

It can work, but it is a pain to deal with. We model around it and print parts that then get assembled if needed.

 

And that is why I'm buying the sigma lol

2 carriages lol
