Bambu Lab
A1 supports one AMS lite for up to four colors. AMS, AMS 2 Pro and AMS HT use the A1-series AMS HUB SA013 with firmware 01.07.00.00 or later. That route supports up to four units, without mixing AMS lite; cable generation and drying conditions still apply.
Creality
Creality’s U.S. product information lists CFS and the K2 Plus PEI frosted build plate; its general replacement guide identifies the K2 Plus integrated nozzle. Hardware fit is not universal material support: TPU must not pass through CFS, and nozzle choice depends on the filament.
Creality
US specifications list 0.2/0.4/0.6/0.8 mm nozzles for K2 Plus, a 350 °C maximum and an included 0.4 mm nozzle. Separately, Creality’s general CF guidance advises against 0.2 mm and prefers 0.6 mm, followed by 0.4 mm, with the documented temperature and cleaning conditions.
Creality
Creality’s U.S. K2 Plus options list up to 4 CFS units and 16-color printing; 1 CFS provides 4 slots. Separately, the general filament guide says not to feed TPU through CFS because it can bend and cause loading or unloading failure.
Anycubic
For the U.S. evidence set, 1 first-generation ACE Pro provides 4-color printing and 2 units provide up to 8 colors. TPU 95A is not compatible with ACE Pro multicolor feeding, so it remains a single-color direct-feed task.
Prusa
MK4S has documented relationships with Nextruder, its high-flow nozzle and PEI sheet, plus optional MMU3. These are different decisions: matching a replacement part, configuring multi-material printing and meeting a material’s enclosure requirement should be checked separately.
ELEGOO
For the U.S. evidence set, the first-generation Centauri Carbon uses a 0.4 mm brass-hardened steel nozzle with a 320 °C maximum. ELEGOO lists carbon/glass-fiber reinforced filament, PLA, PETG, ABS, ASA, TPU, PET, PC and PA, but that list does not remove each material's drying, plate and slicer-profile conditions or establish Centauri Carbon 2 compatibility.
Bambu Lab
For the U.S. A1, Bambu Lab labels PLA, PETG, TPU and PVA ideal. It labels ABS, ASA, PC, PA, PET and carbon/glass-fiber reinforced polymer not recommended. A hardened nozzle does not by itself override the whole-printer material boundary.
