Creality K1 Max vs Bambu P1S: Mid-Range Speed Printers Compared

Two Speed Contenders

The Creality K1 Max (550-600 GBP) and Bambu P1S (600 GBP) sit in the same price bracket, target the same buyer, and promise the same thing: fast, high-quality prints without the premium price tag. But which one actually delivers?

Build Volume

K1 Max: 300x300x300mm - genuinely large, can print functional parts, cosplay helmets, large prototypes.

P1S: 256x256x256mm - still large but noticeably smaller. Fine for most users, limiting for some.

Speed

Both market 500mm/s. Real-world quality printing: 200-300mm/s for both. Benchy times within 2-3 minutes of each other. The speed difference is negligible in practice.

Ecosystem

Bambu P1S: Closed ecosystem, excellent slicer (Bambu Studio), works perfectly out of the box, AMS for multicolour, cloud features. But you're locked in.

Creality K1 Max: More open. Klipper-based, can use third-party slicers, community firmware available. But setup takes longer and quality control is more variable.

Known Issues

K1 Max: Some early units had cooling issues, firmware bugs, and bed adhesion problems. Creality has addressed most with updates, but you may need to troubleshoot.

P1S: Generally more reliable out of the box. Bambu's quality control is tighter. The authentication controversy from 2025 is a consideration if you care about local control.

Who Should Buy Which

Buy K1 Max if: You need the larger build volume, you want more open control, you're comfortable troubleshooting.

Buy P1S if: You want something reliable immediately, you might add multicolour, you don't mind the closed ecosystem.

The Verdict

P1S: Better out-of-box experience, smaller build volume. K1 Max: Larger build volume, more setup work. Both are fast. Pick based on which trade-off matters more to you.
