Which is better for printing large parts?

The K1 Max. Its 300 mm cube gives noticeably more room per axis than the P1S's 256 mm, so large single-piece prints fit that would need splitting on the P1S.

Which is better for multi-color printing?

The P1S Combo. The AMS is included and supports up to 16 colors. The K1 Max ships with a single extruder and no multi-color unit.

Which is more reliable out of the box?

The P1S has the stronger record. Owners rate it 4.8 versus 4.4, and its auto calibration is widely described as hands-off. The K1 Max also self-tests and auto-levels, but needs more tuning for best results.

Is the P1S worth stepping up to over the K1 Max?

If you want multi-color prints and the least fiddling, yes. If your work is large functional parts in one color, the K1 Max's bigger volume and higher speed serve you better.

Which handles high-temperature filaments like ABS and ASA?

Both are fully enclosed and reach 300°C at the nozzle, so both handle ABS and ASA. The K1 Max lists ASA and PA support explicitly; the P1S relies on its enclosure and hotend.

Which is easier to move and fit on a desk?

The P1S. It weighs about 13 kg and is smaller in every dimension. The K1 Max weighs 18 kg and takes up more space.

Creality K1 Max 3D Printer vs Bambu Lab P1S Combo

The Bambu Lab P1S Combo is the better pick for most shoppers. It scores higher with owners, ships with the AMS for multi-color printing, and its software and calibration are widely praised as the most hands-off in this class. The Creality K1 Max wins on build volume: 300 mm per side versus 256 mm, plus a slightly higher top speed. Buy the K1 Max if large single-piece prints matter more to you than multi-color and polish.

Choose the Creality K1 Max if you need the bigger 300x300x300 mm build volume for large single-piece parts and want a fast enclosed printer with AI first-layer monitoring.
Choose the Bambu Lab P1S Combo if you want multi-color printing out of the box, the most reliable auto-calibration, and the stronger owner track record.
