MechAMS V2.2 · compared

An AMS lite alternative for the A1 and A1 mini.

The AMS lite is Bambu Lab's own four-spool unit. MechAMS is eight passive filament stations that you print yourself, driven by the printer's own extruder. Here is what each one does, what each one costs, and which one fits you.

Which one fits you.

Take the AMS lite if

  • you want it finished out of the box, with nothing to build;
  • you print from Bambu Lab spools and want them read for you;
  • you want a backup spool to take over when one runs out;
  • four colours are enough.

Take MechAMS V2.2 if

  • you want up to eight colours on your A1 or A1 mini;
  • you would rather print your upgrade than buy it;
  • you want nothing electronic added, and stock firmware;
  • you like to tune the purge and the change yourself.

How MechAMS changes colour

Your extruder does the work.

The toolhead cuts the filament, docks at the old station to pull it back, docks at the new one to feed the next colour, and purges into a bin at the rear. The G-code generator in your account writes all of it into a printer profile that you pick in Bambu Studio.

A filament change takes 40 to 60 seconds in regular use. Set up for speed, under 30 seconds is possible.

You don't need the AMS Lite or its hub with MechAMS fitted, and no AMS Lite part is reused.

Eight filaments.
The extruder you already own.
