The Elegoo Centauri Carbon put a hardened nozzle, a direct-drive extruder, auto bed leveling, and a fully enclosed CoreXY frame into a printer priced near $299. Features that once cost $600 or more now sit at the entry level. This review covers what the machine does well, where it cuts corners, and who should buy it.
Quick Takeaways
- Price-to-spec ratio: Enclosed CoreXY, 320°C hotend, hardened steel nozzle, and a 256 × 256 × 256 mm build volume at entry-level pricing.
- Speed: Rated up to 500 mm/s with 20,000 mm/s² acceleration. Real-world quality prints land around 150-250 mm/s.
- Best for: PLA, PETG, TPU, and light-duty ABS/ASA/PA-CF printing, plus beginners who want a closed-box machine that works out of the box.
- Trade-offs: The chamber is passively heated only, so large ABS parts can warp. Multi-color needs a different model or a workaround.

What Is the Elegoo Centauri Carbon?
Elegoo built its name on resin printers and the budget Neptune FDM line. The Centauri Carbon is its first serious move into the enclosed, high-speed FDM class, competing with machines like the Bambu Lab P1S and Creality K1C. It is a ready-to-run printer. You unbox it, remove a few transit screws, level the bed with one button, and print.
The “Carbon” name refers to the carbon-fiber-capable hotend. Hardened steel nozzles resist the abrasion of CF and glass-filled filaments, which wear brass nozzles out in a few hundred grams.
Design and Build Quality
Frame and Enclosure
The chassis is a rigid metal frame with a glass-paneled enclosure and a magnetic-latch front door. The sealed design holds heat from the bed, which raises chamber temperatures passively. It also blocks drafts and cuts noise. At typical speeds, expect roughly 50-60 dB under load, which is audible but not disruptive in a home office.
Motion System
The CoreXY layout keeps the heavy motors stationary, so only the toolhead and gantry move. That is what makes high acceleration possible without ringing. Elegoo includes input shaping and pressure advance tuning in firmware, which is a large part of why print quality holds up at speed.
Hotend and Extruder
A direct-drive extruder gives better retraction control and handles flexible filaments like TPU far better than Bowden setups. The hotend reaches 320°C, which covers PLA, PETG, ABS, ASA, TPU, PA, and PC blends. Rated max flow is around 32 mm³/s, which is plenty for a 0.4 mm nozzle.
Build Plate
The textured PEI spring-steel plate is magnetic and removable. Parts typically release after the bed cools. PLA and PETG adhere well, though PETG can bond too aggressively on smooth PEI without a release agent.
Setup: From Box to First Print
- Remove transit locks and foam from the toolhead and bed.
- Connect to Wi-Fi on the touchscreen and update the firmware.
- Run the automatic calibration (bed leveling, input shaping, and flow checks).
- Load filament through the touchscreen.
- Slice in Elegoo Slicer or use the preloaded test file.
Elegoo’s slicer is built on the OrcaSlicer codebase. Profiles also exist for OrcaSlicer, PrusaSlicer, and Cura.
Print Quality and Speed
Recommended Starting Settings
| Material | Nozzle Temp | Bed Temp | Speed (outer wall) | Notes |
|---|---|---|---|---|
| PLA | 210-225°C | 55-60°C | 150-250 mm/s | Door open or lid off for cooling |
| PETG | 235-250°C | 70-80°C | 100-180 mm/s | Add glue stick as release layer |
| ABS/ASA | 250-270°C | 100-110°C | 80-150 mm/s | Keep door closed, avoid large flat parts |
| TPU 95A | 220-235°C | 40-60°C | 25-40 mm/s | Slow and steady wins |
| PA-CF / PET-CF | 270-300°C | 80-100°C | 60-120 mm/s | Dry filament first |
Real-World Results
At 150-200 mm/s, benchy-style tests show clean overhangs, tight corners, and little visible ringing thanks to input shaping. Pushing to 300+ mm/s exposes the usual limits: reduced layer bonding, visible surface artifacts, and cooling that cannot keep up. Treat 500 mm/s as a marketing ceiling. Functional parts print best around 120-200 mm/s with 0.2 mm layers.
Dimensional accuracy is typically within ±0.1-0.2 mm on well-tuned profiles, good enough for press-fit and snap-fit parts with proper tolerance offsets.
Quick Tuning Snippet
Most tuning happens in the slicer, but you can inject commands into your filament’s start G-code. This example sets a safe preheat and primes the line for PETG. Adjust values to match your own profile and the firmware’s supported commands:
M140 S75 ; set bed to 75°C
M104 S200 ; preheat nozzle without oozing
M190 S75 ; wait for bed
M109 S245 ; wait for PETG print temp
G92 E0 ; reset extruder
G1 E5 F300 ; short prime
G92 E0
Check your firmware version before using firmware-specific commands, since Elegoo’s stack is customized.
Materials and Compatibility
| Filament | Compatible? | Difficulty | Comment |
|---|---|---|---|
| PLA / PLA+ | Yes | Easy | Excellent results, open door for cooling |
| PETG | Yes | Easy-Medium | Strong, slightly stringy without tuning |
| TPU | Yes | Medium | Direct drive helps significantly |
| ABS / ASA | Yes | Medium-Hard | Passive heating works for small and mid-size parts |
| PA / PA-CF | Yes | Hard | Needs dry filament, higher temps |
| PC | Limited | Hard | Warping risk without active heating |
Centauri Carbon vs. Competitors
| Feature | Elegoo Centauri Carbon | Bambu Lab P1S | Creality K1C |
|---|---|---|---|
| Price tier | Lowest | Mid | Low-mid |
| Enclosure | Full | Full | Full |
| Hardened nozzle | Yes | No (steel upgrade) | Yes |
| Direct drive | Yes | Yes | Yes |
| Multi-color | Not on base model | AMS option | CFS-style add-ons vary |
| Ecosystem polish | Good, improving | Excellent | Good |
| Active chamber heat | No | No | No |
The P1S still leads in software polish and ecosystem maturity. The Centauri Carbon wins on price per feature, especially the included hardened nozzle. Elegoo has also released a follow-up model, the Centauri Carbon 2, which adds multi-color support. Buyers who want that should check its current price and availability.
Pros and Cons
| Pros | Cons |
|---|---|
| Excellent value for an enclosed CoreXY | No active chamber heating |
| Hardened nozzle included | Single-color on the base model |
| Fast, quiet motion | Software ecosystem smaller than Bambu’s |
| Easy auto-calibration | Max speed claims exceed practical quality |
| Good TPU support | Fewer third-party mods and accessories |
Practical Use Cases
- Functional prototyping: Enclosures, brackets, jigs, and fixtures in PETG or ABS, with tolerances around 0.15 mm.
- Engineering-grade parts: Carbon-fiber nylon gears, spacers, and drone frames, thanks to the hardened nozzle.
- Flexible parts: TPU gaskets, grips, and vibration dampers.
- Small-batch production: Etsy sellers and makers running overnight batches with the built-in camera for monitoring.
- Education and makerspaces: The enclosed design reduces burn risk and drafts, and the auto-calibration cuts setup time.
Who Should Buy It?
Buy it if you want an enclosed, fast printer under $300-$400 and plan to use PLA, PETG, TPU, or abrasive filaments. Skip it if you need active chamber heating for large ABS/ASA/PC parts, or you want native multi-color on day one.
Maintenance Tips
- Clean the plate with isopropyl alcohol every few prints.
- Lubricate the linear rails every 200-300 print hours.
- Dry hygroscopic filaments (PETG, PA, TPU) at 50-70°C for 4-8 hours.
- Replace the nozzle only when worn; hardened steel lasts far longer than brass.
- Run input shaping calibration again after moving the printer.
Frequently Asked Questions
Is the Elegoo Centauri Carbon good for beginners?
Yes. Automatic calibration, a touchscreen interface, and a closed chamber make setup simple. Most users print successfully within an hour of unboxing.
Can the Centauri Carbon print ABS and ASA?
Yes, with limits. The passively heated enclosure handles small and medium parts well. Large, flat ABS parts may warp because the chamber has no active heater.
Does it come with a hardened steel nozzle?
Yes. The standard nozzle is hardened steel, so abrasive filaments like carbon-fiber nylon work without a nozzle upgrade.
How does the Centauri Carbon compare to the Bambu Lab P1S?
The P1S has a more mature ecosystem and an optional multi-color system. The Centauri Carbon costs less and includes a hardened nozzle, making it the better value for single-material printing.
