Bambu Lab A1 mini Combo: Is the AMS lite Worth It at 180 mm

The A1 mini Combo adds the four-spool AMS lite to the A1 mini. It is the cheapest way into multi-colour printing that works reliably. Buy the Combo if colour or dissolvable supports are the point; buy the A1 mini alone if you print one material at a time, because on small parts purge waste is a large share of the filament used.

The purge problem at small sizes
Every colour change flushes the old filament out of the single nozzle. On a 256 mm printer, a big model dilutes that cost; on 180 mm parts a four-colour keychain can spend more filament on purge than on the model. Bambu Studio can reduce flush volumes and use purge as infill, and a poop bucket keeps the waste off the desk. If your multi-colour plans are small logos and lettering, expect that ratio.
When the Combo is right
- Multi-colour toys, signs and models for children, where painting is not an option.
- PLA with a PLA support interface that peels cleanly; see support material for PLA.
- Small farms that want automatic spool switching on runout.
When it is not
- Functional single-colour printing. The printer alone plus a spare plate is the better spend.
- Humid rooms; four exposed spools need a drying routine. The enclosed AMS is P and X series only; see AMS vs AMS lite.
- TPU: it does not go through the AMS lite.
