The Elegoo Centauri Carbon and Bambu Lab P1S land in one of the most commercially relevant buyer decisions in desktop FDM right now: do you buy the lower-cost enclosed CoreXY machine that promises a lot for the money, or do you pay up for the safer mainstream recommendation that has already become the default answer for a huge slice of enclosed-printer shoppers?
That is the real overlap. This is not a random same-category matchup. These two machines make sense for many of the same buyers: people printing brackets, jigs, fixtures, housings, organizers, replacement parts, light small-batch work, and everyday functional pieces who want enclosure benefits without drifting into industrial pricing.
If you are stuck between them, the short version is simple. The P1S is still the easier broad recommendation. The Centauri Carbon gets interesting when value pressure matters more and you want a serious enclosed machine without paying straight into Bambu's stronger ecosystem lane.
Quick answer
Choose the Bambu Lab P1S if you want the safer all-around enclosed recommendation with the more proven mainstream ownership path, cleaner ecosystem confidence, and easier default answer for most buyers. Choose the Elegoo Centauri Carbon if your main goal is getting into a modern enclosed CoreXY printer at a lower spend and you are willing to accept that it is the more price-sensitive value play rather than the default pick for everyone.
What each printer is really for
Elegoo Centauri Carbon
The Centauri Carbon is for buyers who want an enclosed CoreXY machine with a stronger material story than open-frame starters usually offer, but who still care hard about cost discipline. It fits people moving up from bedslingers, buyers comparing value-enclosed machines closely, and users who want a more contained bench setup without paying straight into Bambu's stronger brand position.
Bambu Lab P1S
The P1S is for buyers who want a fast enclosed printer that feels easier to recommend to almost anyone doing mainstream functional work. It fits home users, makers, and small shops who care about throughput, lower friction, optional AMS expansion, and a machine that already sits in the center of a well-established buying conversation.
Where the Bambu Lab P1S usually wins
- buyers who want the safer broad recommendation in this category
- users who care more about ecosystem confidence and day-to-day ownership smoothness than squeezing every dollar
- shoppers who want optional multicolor expansion through AMS
- small shops that would rather standardize around the more established mainstream path
- people who want an enclosed machine without having to defend the decision too much afterward
Where the Elegoo Centauri Carbon usually wins
- buyers who are heavily value-driven but still want an enclosed CoreXY machine
- users who want enclosure benefits and broader material ambition without paying the Bambu premium
- shoppers who see carbon-fiber-ready positioning and lower entry cost as part of the point
- makers moving up from older open printers who want a more serious machine while keeping spending tighter
- buyers comparing the whole value-enclosed field, not just following the mainstream default
The real decision: safer mainstream ownership or stronger value pressure?
This comparison is less about whether either machine can print useful parts and more about how much risk and friction you are willing to accept in exchange for spending less. Both printers belong in the same broad lane of enclosed everyday functional printing. Both are meant to feel faster and more contained than older hobby machines. Both make more sense than open printers when you want a cleaner path into ABS, ASA, and tougher utility work.
The difference is where the buying confidence comes from. With the P1S, the pitch is that the machine already owns the broad mainstream lane. It is the reference point a lot of buyers are already comparing against. With the Centauri Carbon, the pitch is that you may get enough of that enclosed modern-printer benefit while spending less, which matters a lot if the printer budget is real and not theoretical.
Materials, enclosure, and workflow differences that actually matter
For PLA and PETG work, both printers can cover a lot of normal output. The more important questions start when your work shifts toward tougher functional parts, cleaner containment, and ownership expectations around a more enclosed workflow.
The P1S is easier to frame around overall buying confidence. It is already widely understood as a machine for fast everyday functional printing with enclosure benefits and a straightforward growth path if you later care about multicolor work. That matters if you are buying one machine that needs to cover a lot of ground without turning into a debate every time somebody asks whether you chose the right one.
The Centauri Carbon is easier to justify when the budget line is real and you still want to move into a modern enclosed machine that feels materially more serious than a cheaper open starter. Its appeal is strongest when you are deliberately shopping the value-enclosed category rather than simply asking for the single safest answer.
If you expect AMS-style multicolor expansion to matter, the P1S has the cleaner story. If you mostly care about getting an enclosed CoreXY printer for functional parts, materials beyond casual PLA, and a more contained bench without spending as much, the Centauri Carbon becomes easier to defend.
Who should buy the Bambu Lab P1S?
- buyers who want the safest mainstream enclosed recommendation
- small shops and home operators who want lower-friction ownership
- users who care about optional multicolor expansion and a stronger ecosystem story
- shoppers who would rather pay more once than second-guess the machine choice later
Who should buy the Elegoo Centauri Carbon?
- buyers who want to keep spend tighter while still moving into enclosed CoreXY printing
- users upgrading from older open-frame machines who want a clearer step up in containment and material range
- value-driven shoppers who are willing to accept a less default recommendation in exchange for stronger price discipline
- readers who care more about the category jump than about having the strongest mainstream ecosystem around the machine
What makes each one harder to justify?
Why the Bambu Lab P1S can be hard to justify
The P1S gets harder to justify when budget pressure is the main constraint and you are not convinced the stronger ecosystem and broader buyer confidence are worth the extra spend. If your buying lens is value-first, not safest-first, the P1S can start to feel like the more expensive comfort choice.
Why the Elegoo Centauri Carbon can be hard to justify
The Centauri Carbon gets harder to justify when you step back and realize you mostly want the easiest mainstream answer with the least explanation attached. In that case, the P1S is still the cleaner recommendation because it carries more established buyer confidence, a stronger broad support story, and a more obvious growth path.

Editorial take
The Bambu Lab P1S is still the better recommendation for most buyers because it is the safer center-of-market answer. It is easier to trust as the default enclosed machine for functional printing, easier to recommend to mixed-skill users, and easier to justify when you want one machine that does a lot without much drama.
The Elegoo Centauri Carbon still has a real lane. It is the one to look at when the budget matters enough that the standard P1S answer starts to feel lazy. If you want the enclosed CoreXY step up, want stronger material ambition than open machines usually offer, and want to control spend harder, the Centauri Carbon becomes a serious alternative instead of a throwaway budget mention.
If you are stuck, use this filter: if you want the safer answer, buy the P1S. If you want the value-enclosed answer and are shopping with a tighter budget on purpose, buy the Centauri Carbon.
Common questions
Is the Elegoo Centauri Carbon better than the Bambu Lab P1S?
For most buyers, no. The Bambu Lab P1S is still the cleaner all-around recommendation when you want a safer mainstream enclosed pick. The Elegoo Centauri Carbon becomes more interesting when controlling spend is a major part of the purchase.
Which printer is better for functional parts?
Both can work well for functional parts, but the P1S is easier to recommend broadly because its ownership path is better established. The Centauri Carbon makes sense when you want enclosure benefits and broader material room without climbing as high on price.
Which one is the smarter first enclosed machine?
The P1S is the safer first enclosed machine for most people. The Centauri Carbon is more of a value-led move for buyers who already know why they want an enclosure and are willing to trade some safety in the recommendation for lower spend.
When should you compare something else instead?
Compare something else when your real choice is between entry-level enclosed value options like the K1C or Q1 Pro, or when you already know you want to step above this tier into something like the Prusa CORE One.
