Can the K1C print ABS?

Yes. The enclosure and hotend reach the temperatures ABS needs, and the chamber reduces warping. Large ABS parts can still split because the chamber is not actively heated.

Is it better than the K1?

The K1C adds a hardened steel nozzle, upgraded cooling and a camera, so it handles abrasive filament and monitors prints better. The motion system and speed are essentially the same.

How does it compare with the Bambu Lab P1S?

The P1S has a more polished app, automatic calibration and multi-color support with the AMS. The K1C is simpler to service and quieter on paper, but its software is less refined.

Does it come assembled?

It ships mostly assembled. You attach a few parts, remove shipping braces and run calibration, which most owners finish in under an hour.

What filament can it run?

PLA, PETG, ABS, TPU and most filled filaments work. The hardened nozzle suits carbon-fiber and glow-in-the-dark material; high-temperature engineering plastics need a hotter hotend.
