Most of the multi color printers out there are AMS/MMU or similar, and there are many DIY options, like Armored Turtle or ECF.
They are an evolutionary dead end. Slow, wasteful, expensive to run.
The Prusa XL, or the Snapmaker U1 are the future direction.
Also a good CoreXY machine like vorons/sovols/ratrigs/VZ, etc can be upgraded with the Bondtech INDX tool changer.
We are talking 5x lower print times, 5x lower material costs.
There is going to be a glut of used Bambus and other multi material unit printers, when print farms unload them, since the tool changers will massively boost their bottom line.

So I have a FlashForge AD5X with the MMU. It worked amazing out of the box, including flawlessly doing some TPU. They actually mentioned the MMU was designed with TPU in mind. That being said: I have been struggling with basic PLA, even after swapping to nozzle that has run only PLA (even though I only ran <10g of TPU through it). I am still new to a lot of this, and don’t feel experienced enough to fault the hardware. What I can say though is it does seem folks are specifically improving the ability of MMUs to handle flexibles. A big reason I got it was to be able to do ABS parts with TPU gaskets. Ask me in a few months.
