The Truth About Multicolor 3D Printing (And Why Manual is Sometimes Better)

Let's talk about multicolor 3D printing. Honestly, right now, the only automated multicolor setups that truly respect your time are multi-toolhead or IDEX (Independent Dual Extruder) printers—think the Snapmaker U1, Prusa XL, or the Flashforge Creator series.

While single-nozzle systems with automatic material switchers (like the Bambu Lab X1C with AMS) are incredibly popular, they come with a massive catch: they generate a ton of plastic waste and add hours to your print time because the machine constantly has to cut, swap, and purge filament. Multi-toolhead printers bypass this waste, but they cost a fortune.

The "Just Cut It" Method

So, what's the best way to get multicolor parts without the headache? Just cut the model into pieces.

Instead of trying to print everything in one go, split your model in your slicer, print the individual parts in single colors, and glue them together later. There’s no need to constantly load and unload filament, it’s significantly faster, and it wastes zero material.

(Side note: You can still do manual multicolor on a standard printer by setting up a pause in your slicer at a specific layer height so you can swap the filament yourself. This works great for flat things like nameplates, but it's way too tedious for complex, 3D models).

And also as a gotcha, you need to know a little more about 3D to be able to cut and separate objects into multi color sections. You can check a sample workflow in this tutorial

The Verdict

Even with the introduction of multi-toolhead printers that cut multicolor printing time in half, there is a hard truth to swallow: buying two or three affordable, single-color printers is still cheaper and faster than buying one high-end multicolor machine. You can print all your different colored parts simultaneously across a few machines, assemble them, and have the finished product in your hands before an automated single-nozzle printer even finishes its purge tower.
