Head-to-head

Snapmaker U1 vs Bambu Lab P1S: toolchanger or AMS?

Both printers cost about the same with multi-colour hardware, but they solve colour changes in opposite ways. The U1 swaps four complete toolheads; the P1S feeds four spools into one nozzle through the AMS.

Which should you buy?

Pick the Snapmaker U1 if you print multi-colour or multi-material parts often: toolhead swaps waste far less filament and finish sooner. Pick the Bambu Lab P1S if you print mostly single-colour, want an enclosure out of the box for ABS and like Bambu’s polished app ecosystem.
