Bambu Lab P1S vs Creality K1C: two enclosed CoreXYs, two ecosystems
The Creality K1C ships a hardened quick-swap nozzle and a clog-resistant extruder for carbon-fibre filament, runs a Klipper-based system with a web page you can upload to from a phone, and launched at $559 with a 220 x 220 x 250 mm bed. The Bambu Lab P1S has the larger 256 mm bed, the AMS for multi-colour and the more polished software, at $699 at launch, with a stainless nozzle. Buy the K1C for abrasive filament and an open web interface; buy the P1S for bed size, colour and an ecosystem that just works.Who should buy which
Both printers are in SpeakCAD's slicer catalog with their official OrcaSlicer profiles, so this page has no printer to sell you. The numbers in the table come from those profiles; the prices are the makers' launch prices, and prices moved in 2025 and differ by region.Buy the K1C if…
You want carbon-fibre filament out of the box, a Klipper web interface that takes a G-code upload from a phone browser, OrcaSlicer, and a lower price. You do not need multi-colour.Either way, the first custom part
Describe it with its measurements, check it on a virtual bed the size of the printer you chose, and download a sliced .gcode.3mf for the P1S or G-code for the K1C, sliced with its official profile. The first render usually appears within a minute or two: a new part gets deeper reasoning through the geometry, and small edits land in seconds.Bambu Lab P1S vs Creality K1C: the numbers

Parts that fit both beds
Copy one, change the numbers to yours. Each opens in the editor with the text already typed.“A drawer organizer 200 x 140 x 45 mm outside, 1.6 mm walls, four equal compartments along the length, a finger notch on the front edge of each divider.”
Open this prompt in the editor“A spool holder with two 608 bearing rollers 80 mm apart for a 200 mm spool, 200 mm wide base, 2.4 mm walls.”
Open this prompt in the editor“A wall bracket for a 40 mm wide power strip: two 4.5 mm countersunk screw holes 60 mm apart, 2.5 mm walls, a 3 mm lip that holds the strip.”

Both are enclosed CoreXY printers with a passive chamber, an air filter, a camera, 300 °C hotends and 600 mm/s class motion. Both print ABS and ASA well and PLA with the door open.
Where the K1C wins
- Abrasive filament: the hardened "unicorn" nozzle and the clog-resistant extruder are standard; the P1S needs an upgrade kit.
- Network from a phone: Creality OS is Klipper-based with a web page on the LAN, so a G-code file made on a phone uploads from the browser. The P1S wants the microSD card or Bambu Studio on a computer.
- Price: $559 against $699 at launch.
- Slicers: Creality Print, or OrcaSlicer directly with the printer's profile.
Where the P1S wins
- Bed: 256 x 256 mm against 220 x 220 mm, which matters for organizers and racks.
- Multi-colour: the AMS was designed in and chains to 16 spools; the K1C's CFS came later, as an add-on for the K1 series.
- Ecosystem: Bambu Studio, Handy, MakerWorld profiles and a very large user base; fewer surprises.
- Auxiliary fan: better cooling of PLA at speed inside the box.
What both give up
Neither has a heated chamber. The P1S's screen is small and not a touchscreen; the K1C's firmware is less open than plain Klipper (root access exists, but the vendor controls updates).
Prices
Launch prices above; both changed in 2025 and vary by region.
Verdict
The K1C is the better buy for engineering filaments and for a phone-first workflow; the P1S is the better buy for a bigger bed, colour and the smoothest software. On PLA and PETG alone, either prints well and the K1C costs less.
Sliced for either one
SpeakCAD ships the OrcaSlicer profiles of the Bambu Lab P1S and the Creality K1C, like 380+ other printers. Describe a part in plain English on a phone or a computer, watch it render on a virtual bed of the size above, change it by chat, and download a sliced .gcode.3mf for the P1S or G-code for the K1C, with the print time and filament weight. The STL and 3MF are always there for your own slicer. The Bambu Lab P1S and Creality K1C pages have prompts sized for each bed and the library parts made for them.
Questions
The P1S: 256 x 256 x 250 mm against the K1C's 220 x 220 x 250 mm in the OrcaSlicer profiles. Both fit most functional parts; the P1S fits wider trays and racks in one piece.
Yes. OrcaSlicer ships profiles for both; Bambu's own slicer is Bambu Studio and Creality's is Creality Print. SpeakCAD slices with the OrcaSlicer profile of each and gives the P1S a .gcode.3mf and the K1C a .gcode file.
Only with the CFS add-on Creality released later for the K1 series (the slicer catalog carries a K1C CFS profile). The P1S takes the AMS from day one.
Yes, both, with the OrcaSlicer profile each maker ships: a sliced .gcode.3mf for the P1S and G-code for the K1C, or an STL or 3MF for your own slicer. The bed sizes in the table are the ones the viewer shows while you design.
