Creality K1C vs Elegoo Centauri Carbon: two hardened-nozzle enclosed printers
Both are enclosed CoreXY printers with a hardened nozzle and extruder for carbon-fibre filament, a camera and a filter. The Elegoo Centauri Carbon has the larger bed (a 256 mm cube against 220 x 220 x 250 mm) and launched at $299; the Creality K1C launched at $559 with a Klipper-based web page you can upload to from a phone, a quick-swap nozzle and a longer track record. The Centauri Carbon is the value pick; the K1C is the pick for a phone-first, Klipper workflow.The short version
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.2
Buy the Centauri Carbon if…
You want the bigger bed and the lower price, a hotend to 320 °C, and are happy with ElegooSlicer or OrcaSlicer, Wi-Fi from a computer and a USB stick.3
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 G-code for the K1C or G-code for the Centauri Carbon, 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.Creality K1C vs Elegoo Centauri Carbon: 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.”

Enclosed CoreXY, hardened nozzle and gears, 500 to 600 mm/s ratings, a camera, an air filter, a touchscreen. Both print ABS, ASA and carbon-fibre blends without upgrades.
Where the Centauri Carbon wins
- Bed: 256 x 256 x 256 mm against 220 x 220 x 250 mm.
- Price: $299 against $559 at launch.
- Hotend: 320 °C against 300 °C.
Where the K1C wins
- Network from a phone: Creality OS exposes a Klipper-style web page on the LAN; a G-code file made on a phone uploads from the browser. The Centauri Carbon sends from ElegooSlicer on a computer or takes a USB stick.
- Nozzle swap: the unicorn nozzle changes as a unit.
- Maturity: a year more of firmware and community fixes.
- OrcaSlicer profiles have existed longer.
What both give up
Neither has a heated chamber, and multi-colour is an add-on at best (the K1 series CFS came later for the K1C; the Centauri Carbon had none at launch). Both are vendor-firmware machines: more open than Bambu, less than plain Klipper.
Prices
Launch prices above; both changed in 2025 and vary by region.
Verdict
The Centauri Carbon wins on bed size and price by a margin that is hard to argue with. The K1C is worth its premium if uploading from a phone over the network and the quick-swap nozzle are part of your routine.
Sliced for either one
SpeakCAD ships the OrcaSlicer profiles of the Creality K1C and the Elegoo Centauri Carbon, 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 G-code for the K1C or G-code for the Centauri Carbon, with the print time and filament weight. The STL and 3MF are always there for your own slicer. The Creality K1C and Elegoo Centauri Carbon pages have prompts sized for each bed and the library parts made for them.
Questions
Yes. Both ship a hardened nozzle and hardened extruder gears, which is what abrasive filament needs. Neither has a heated chamber, so large PA-CF parts may still warp.
The K1C's Creality OS is older and its web page is a plain Klipper interface, which many owners prefer. ElegooSlicer is an OrcaSlicer fork and works well; the printer-side software started later and matured through 2025.
Yes: 256 x 256 x 256 mm in the OrcaSlicer profile SpeakCAD slices with, the same footprint as a Bambu Lab P1S.
Yes, both, with the OrcaSlicer profile each maker ships: G-code for the K1C and G-code for the Centauri Carbon, or an STL or 3MF for your own slicer. The bed sizes in the table are the ones the viewer shows while you design.
