Show Notes
Both multi-color AMS printing and soluble supports run on the same filament-swap mechanics, so both cost you extra material and time you should budget for before you press print.
In this episode you'll learn:
Bambu Lab introduced the AMS in May 2022 alongside the X1 Carbon; the box has four slots, two desiccant compartments, and a humidity sensor but no heater, so it keeps filament dry rather than actively drying it.
A standard 0.4 mm hotend holds roughly 50 to 100 mm3 of molten plastic, so the first few centimeters after each color change carry the old color and must be flushed to a purge tower, a purge object, or the infill.
UltiMaker's data sheet lists PVA with a glass transition of 58.4°C, a melting temperature of 175.4°C, and a density of 1.23 g/cm3; PVA dissolves in plain water and is biodegradable.
Prusa recommends HIPS at a 225°C to 255°C nozzle and a 100°C to 110°C bed, the same range as ABS, and HIPS dissolves in limonene or acetone.
Bambu Lab's general support guide states PVA is not compatible as a support for PETG, and for the H2D warns against printing PVA and PETG at the same time from the left and right nozzles; Prusa recommends BVOH for PETG instead.

Both articles help K1 and K1C owners read what their printer is actually telling them when a print stops, from Klipper shutdown messages to AI camera alerts, so they fix the real cause instead of swapping parts.
Buying PLA smartly in 2026 means matching the spool to your printer and prints, then using real usage numbers (meters per kilogram, scale weighings) so you buy the right amount and never run out mid-print.
Every Prusa error screen on the MK4, MINI, XL, CORE One and MK3.5 carries a five-digit XXYZZ code that tells you the device and problem category, and for MMU2S and MMU3 owners the 04xxx family shows whether a stopped multicolor print needs a cleaned filament path, a checked cable
Both articles argue that under $600 the real choice is not price but design, an open bedslinger with a polished ecosystem (Bambu A1, Kobra 3) versus an enclosed CoreXY box (K1C, Centauri Carbon), and you should pick based on what you plan to print.
Both articles center on the enclosed print chamber: the H2S adds an actively heated one over the passive X1C, and choosing a printer or an enclosure comes down to which filaments actually need that sealed, warm environment.
