Elegoo Centauri Carbon Review 2026: The £239 Verdict

The Elegoo Centauri Carbon does something that was not supposed to be possible at this price. A fully enclosed CoreXY printer with a 320°C hardened steel nozzle, 500mm/s top speed, built-in camera and the auto-everything feature set that used to live on machines costing £700 or more, for around £239. Two years ago this configuration cost three times as much. The shape of the budget FDM market has changed, and the Centauri Carbon is the reason.

For most people considering a sub-£300 printer in 2026, this is the one I'd buy. If you want to print carbon fibre and other abrasive filaments, or you want an enclosed chamber for ABS without spending closer to £700 on a Bambu P1S, you can have it on the Centauri Carbon on Amazon UK right now. There are real trade-offs against pricier machines, but they are smaller than the price gap suggests. Prices checked May 2026.

## What It Is

The Centauri Carbon is Elegoo's first serious CoreXY printer, and the first machine from a major brand to put a fully enclosed CoreXY frame, hardened steel hotend and 500mm/s motion system at this price point. Build volume is 256x256x256mm, which is the same as the Bambu P1S and meaningfully larger than most printers under £250. The chamber runs warm enough for ABS and ASA without warping, and the hardened steel extruder gears plus 320°C nozzle let it print carbon fibre filaments without chewing through a brass nozzle in a week.

It runs Elegoo OS, an Orca-based slicer that handles network slicing, time-lapse camera capture and over-the-air firmware updates. Build plate is PEI flex, auto-leveling is one-touch with Z-offset compensation, and there are filament runout sensors, power-loss recovery and chamber LEDs. Most of the quality-of-life features people pay Bambu Lab £400 more for are present on this machine. The frame is integrated die-cast aluminium, not bent sheet metal, which keeps vibration genuinely low at speed.

Setup is shorter than the spec sheet implies. The printer ships fully assembled with the toolhead, hotend and gantry already calibrated, so the only real assembly is removing transit foam and clipping the spool holder onto the back. First boot runs through Wi-Fi pairing, an auto-bed-level calibration and a quick first-print test. Most owners report a working print within an hour of opening the box, which puts this on par with Bambu Lab's out-of-box experience and substantially ahead of the Ender-class kits where assembly and tramming can eat a full evening before the first print starts.

## The Case For It

The price is the headline, but the engineering decisions behind it matter more. Three things stand out.

First, the enclosure is genuinely useful, not cosmetic. A fully enclosed chamber means consistent temperatures across long prints, which matters more than most people realise for warp control on PETG and ABS. It also makes the printer safe to run in a room with kids and pets, and quieter than the open-frame Ender-class machines it replaces. Integrated carbon filters cut down on styrene fumes during ABS and ASA work. The lid lifts off when you want to print pure PLA without trapping too much chamber heat.

Second, the hardened steel hotend plus hardened gears means abrasive filaments are on the table from day one. PLA-CF, PETG-CF, PA-CF, glow-in-the-dark and glass-filled materials all print without upgrades. These are the filaments that destroy a stock brass nozzle in a few hundred grams of printing on a typical budget machine. For anyone making functional parts, drone frames, or anything where stiffness-to-weight matters, this single capability justifies the price gap over a Kobra 2 or Ender 3 V3 KE.

Third, the everyday usability is in the same league as machines costing twice as much. The auto-bed-level routine runs at the start of every print with Z-offset compensation. The built-in camera streams to the slicer and creates time-lapses without a Raspberry Pi mod. Run-out detection pauses the print when filament breaks or runs dry. Power-loss recovery resumes from the last layer after a power cut. The Orca-based slicer is the same slicer most enthusiasts already use, so there is no proprietary lock-in, gcode is standard, and the community can build custom profiles for any filament.

500mm/s is achievable in practice, not just a marketing number. Real-world print speed on PLA benchies sits comfortably around 250 to 350mm/s with good surface quality, and the 20,000mm/s² acceleration handles input-shaped fast moves without the ghosting you would see on lighter frames. Owner reports across the Elegoo subreddit and early reviews from VoxelMatters, Make: and Hackster.io describe the long-print reliability as much better than the K1-era Creality machines they sit next to in this category.

Fourth, the build surface is the right one for this price tier. The PEI flex plate is dual-sided with a smooth face for glossy bottoms and a textured face for grippy first layers, and prints pop off without scrapers once the bed cools. Owners report consistent first-layer adhesion across PLA, PETG and PLA-CF with stock profiles, which is the single most common point of frustration on cheaper printers. A working bed surface from day one is worth more in actual print success rate than another 50mm/s of headline speed.

## The Honest Case Against It

The biggest limitation is what it does not do out of the box: multi-colour. The base Centauri Carbon is single-material. Elegoo's CANVAS multi-colour module retrofits to it, but adds around £170 and is still maturing. If multi-colour printing matters on day one, the Bambu A1 Mini with AMS Lite is a more proven path, even at the cost of a smaller build volume.

Owner community is still small compared with Bambu and Creality. There are fewer YouTube tutorials, less mod ecosystem, and fewer community-tested print profiles for unusual filaments. That is changing quickly, but right now if something unusual breaks, the answer might not be searchable yet.

Elegoo OS is good but new. The slicer integration is smooth, the camera works reliably, but the printer's onboard menus have a few rough edges and the earliest firmware revisions had bugs that updates have been steadily fixing. Anyone who hated waiting for K1 firmware fixes in 2024 will want to watch the Elegoo subreddit for a couple of months before assuming everything is rock-solid.

And the 256x256x256mm build volume, while fine for most projects, is not large. Helmets, big cosplay armour, and tall mechanical prints will need to be sectioned. If you know you'll print big, the [Best 3D Printer UK guide](/guides/best-3d-printer-uk) covers larger-format options worth considering.

Footprint and noise are worth knowing too. The enclosed cabinet measures roughly 450mm wide by 450mm deep by 510mm tall, larger than an Ender 3 and meaningfully more shelf-hungry than the A1 Mini. Steady-state print noise sits around 50 to 55dB, quieter than open-frame Crealitys but not silent. If desk space is tight, the A1 Mini stays the right call. If the printer lives in a workshop or garage, the Centauri Carbon's size is the same as anything CoreXY in its class.

## Who Should Buy It, Who Shouldn't

Buy the Centauri Carbon if: you want one printer that handles PLA, PETG, ABS and carbon fibre filaments without upgrades. You want a safe, quiet, enclosed machine for a shared living space, not a screaming open-frame in the corner of the office. You are upgrading from an Ender-class printer and want a real step up without spending Bambu money. You value an open ecosystem where any slicer works and any filament profile can be tuned.

Don't buy it if: you need multi-colour printing on day one. See the [Best 3D Printer for Beginners UK guide](/guides/best-3d-printer-beginners-uk) where the A1 Mini with AMS Lite is the better pick. You need a build volume over 256mm, in which case the Best 3D Printer UK guide covers larger options like the Creality K1 Max. You want resin-grade detail for miniatures or jewellery. The [Best Resin Printer UK guide](/guides/best-resin-printer-uk) is the right starting point instead.

## Compared To The Obvious Alternatives

The three machines anyone shortlisting the Centauri Carbon is also looking at:

Bambu Lab A1 Mini (around £280 with AMS Lite). Cheaper, multi-colour ready, simpler to set up, and physically smaller. The A1 Mini is the right call for absolute beginners who want plug-and-print and care more about colourful PLA models than carbon fibre engineering parts. The Centauri Carbon is the right call for anyone who wants an enclosed chamber, a larger build volume, and abrasive-filament capability. Different tools for different jobs, both excellent at what they do. My recommendation depends entirely on whether multi-colour or material capability is the priority.

Bambu Lab P1S (around £680). The closest like-for-like comparison. The P1S adds AMS multi-colour, a more mature ecosystem, and Bambu's polished software stack. It also costs roughly three times as much. Unless you specifically need AMS multi-colour or are already brand-locked into Bambu, the Centauri Carbon gets you 80% of the P1S experience for 35% of the price. The P1S remains the safer choice for someone who values ecosystem maturity over money saved, and I would still recommend it for anyone who knows they want multi-material printing reliably from day one.

Creality K1C (around £430). Creality's earlier attempt at enclosed CoreXY at this price tier. The K1C is older, runs Creality's proprietary slicer, and had a difficult launch with firmware issues that took most of 2024 to settle. The Centauri Carbon learns from those mistakes with an open slicer, a cleaner build, and better cooling. The K1C is still a decent printer if it is discounted heavily, but at full price the Centauri Carbon is the better engineered machine.

Anycubic Kobra S1 Combo (around £580). Anycubic's enclosed CoreXY answer to the Bambu A1 ecosystem, with a multi-colour ACE Pro module bundled in. The S1 Combo gets multi-colour out of the box, which the Centauri Carbon does not. It also costs more than twice as much, runs Anycubic's slicer rather than Orca, and has a smaller community than either Bambu or Elegoo. If multi-colour is essential and Bambu's ecosystem feels too locked in, the S1 Combo is worth a look. Otherwise the Centauri Carbon is the better value at this build volume and material capability.

Owners who have run the Centauri Carbon for a couple of months tend to settle into the same routine: a quick PEI wipe with isopropyl every few prints, an occasional nozzle change when switching between carbon-fibre and plain PLA, and a chamber filter swap every few months for ABS work. Build-plate wear is slow on the textured side, and the steel-geared extruder shows no measurable wear after 5kg of PLA-CF in early owner reports. That is the kind of long-term picture that decides whether a budget printer is genuinely good value or just cheap up front, and the early signs point to the former.

## What I'd Buy Today

The Elegoo Centauri Carbon. For the price of an Ender 3 V3 SE plus £70, you get enclosed CoreXY, abrasive-filament capability, a working camera, and most of the quality-of-life features Bambu Lab charges £400 more for. The trade-offs are a younger community and no multi-colour out of the box. For most people printing single-material functional and decorative parts, those are reasonable prices to pay.

Buy direct from Elegoo UK — at around £239 it is typically a few pounds cheaper than Amazon UK, and you are buying from the manufacturer with full warranty support. Unbox it, run the auto-calibration, load a spool of PLA, and print. The first benchy will look better than the last benchy you printed on whatever you are upgrading from.
