H2C is all you need
About a week ago, I placed an order for the H2C Multi-Color All-in-One Kit (likely the mainland China version of the "Ultralaytic" kit), which includes 2 AMS2Pro units and 1 AMS HT.
At the time of purchase, I also added a large number of hotend nozzles (around 20), along with a TPU auxiliary feeding module, a filament switcher, and an additional AMS HT.
The next day, I received most of the packages and couldn't wait to start testing various multi-color models, while also printing a large waste bin for it (though it's hard to fill up). Now my "fully equipped" H2C includes 3 AMS2Pro units, 2 AMS HT units, one TPU auxiliary feeder, and one filament switcher, which I absolutely love.
It is undoubtedly the best device I have ever seen. Although this might sound like a promotional post, unfortunately, BambuLab hasn't paid me a cent—instead, I've already spent around $5,000, not including my 80kg of various filaments (which also includes ABS and ASA).
Trust me, if money were no object, it would definitely be your best choice in the world of 3D printing.
