Choose the Bambu Lab P2S when nylon is occasional work inside a broader PLA, PETG, TPU, and enclosed-printing queue. Choose the current Prusa CORE One+ when repeat nylon jobs make its listed 55 C heated chamber, repair access, and serviceability worth prioritizing. If you cannot name recurring nylon parts, do not let one aspirational spool choose the printer.
The P2S has the larger nominal X-Y area and an easier convenience-first ownership case. The CORE One+ adds 14 mm of listed Z height and active chamber control. Neither removes nylon drying, exact-grade profile work, ventilation, wear checks for carbon- or glass-filled nylon, or representative-part qualification.
| Decisive check | Bambu Lab P2S | Prusa CORE One+ | Nylon buying rule |
|---|---|---|---|
| Build volume | 256 x 256 x 256 mm | 250 x 220 x 270 mm | P2S has about 19% more nominal X-Y area; CORE One+ has 14 mm more Z |
| Chamber | Enclosed; Bambu says no active chamber-heating function | Heated enclosed chamber up to 55 C listed | CORE One+ has the clearer repeat-nylon chamber case |
| Filled nylon | Hardened-steel nozzle and extrusion system listed | Current listing says consider a hardened nozzle for abrasive materials | Verify the exact nylon-CF or nylon-GF maker's hardware guidance |
| Ownership fit | Broad enclosed convenience and ecosystem integration | Chamber control and serviceability-first process ownership | Choose around recurring accepted parts, not one hardest material |
Check real capacity with the P2S build-volume guide and CORE One build-volume guide. Then use the existing P2S nylon guide and CORE One nylon guide. Resolve nylon drying, filled-nylon nozzle wear, and nylon warping before treating the printer alone as the fix.
Source and scope: build volume, chamber, and material-hardware claims were rechecked August 24, 2026 against Bambu Lab's current P2S and Prusa's current CORE One+ pages. Do not copy current CORE One+ claims backward to an original or used CORE One without checking the exact machine. This is manufacturer-documented buyer analysis, not hands-on nylon testing.

Use the broader P2S versus CORE One comparison when nylon is not the deciding material. For the material-specific ownership view, open the P2S nylon guide or CORE One nylon guide, then resolve filled-nylon nozzle wear and nylon drying.
Direct answer: Buy the Bambu Lab P2S when nylon is an occasional branch inside a broader PLA, PETG, TPU, and enclosed functional-printing queue. Buy the Prusa CORE One when repeat nylon jobs are important enough that controlled chamber behavior, repair access, and long-term process ownership outweigh the convenience of the broader Bambu default. If you cannot name recurring nylon parts, neither printer should win because of one aspirational spool.

Check the exact CORE One version before comparing
Prusa's current retail page now labels the updated machine CORE One+ and states a heated enclosed chamber up to 55 °C. Buyers comparing an original CORE One, a used unit, or remaining inventory should not copy every current CORE One+ claim backward. Confirm the exact machine, nozzle, firmware, filtration setup, and material profile before buying. The current Prusa product listing and the current Bambu Lab P2S listing are the manufacturer checkpoints used for this refresh.
Quick comparison for nylon buyers

|---|---|---|
| Best-fit nylon role | Occasional nylon inside a broad enclosed-material queue | Recurring nylon inside a serviceability-first enclosed workflow |
| Chamber buying case | Enclosed Adaptive Airflow platform; prove the exact nylon job and profile | Current CORE One family listing emphasizes active chamber temperature control up to 55 °C |
| Ownership posture | Convenience and ecosystem integration first | Repair access, replaceable parts, and owner control first |
| Abrasive nylon warning | Nylon-CF and nylon-GF can require wear-resistant hardware; verify the exact printer, nozzle, and filament-maker guidance | |
| Shared non-negotiable | Dry filament, controlled storage, a qualified profile, ventilation, and a representative-part proof run | |
| Main overbuy risk | You buy an enclosed default but never establish a stable nylon process | You pay for a tougher-material ownership lane that the real queue rarely uses |

Run a 10-job nylon audit before choosing
Review the last ten representative parts you printed, outsourced, delayed, or redesigned. Do not count ideas. Count jobs with a reason to use nylon.
- Why nylon? Record whether the part needs fatigue resistance, impact behavior, wear behavior, temperature performance, or another property that PLA, PETG, ASA, or a different material did not satisfy.
- How often? Separate one-off experiments from repeat work. A recurring monthly queue supports a specialized ownership decision more than a single prototype does.
- Which nylon? Unfilled nylon and carbon- or glass-filled nylon are not the same hardware decision. Record the exact brand and grade.
- What failed? Note wet filament, warping, weak layer bonding, nozzle wear, poor bed adhesion, profile drift, or post-print moisture changes instead of calling every failure a printer problem.
- What did outside production cost? Include lead time, qualification, rejected parts, operator time, and the cost of maintaining an in-house process.
If only one or two jobs survive that audit, keep the broader printer choice separate from the nylon edge case. If several repeat jobs survive and chamber or maintenance control is the recurring constraint, the CORE One branch becomes easier to defend.
Where the Bambu Lab P2S wins
The whole queue still matters more than the hardest spool
The P2S is the cleaner choice when the printer will spend most of its life on ordinary functional work and nylon appears only occasionally. One machine can then remain the broad enclosed default instead of being selected around the most demanding material you might use.
Convenience can be the higher-value constraint
A small shop may value integrated slicing, monitoring, material handling, and a familiar Bambu workflow more than a serviceability-first ownership model. That is legitimate when accepted everyday output, not maximum nylon ambition, drives the purchase.
It is easier to reject when nylon is only a fantasy workload
The P2S should not be sold as a magic nylon appliance. Open the P2S nylon buyer guide and prove one exact grade, profile, drying method, and part before expanding the claim to a whole production queue.
Where the Prusa CORE One wins
Its chamber strategy is easier to tie to repeat nylon work
Prusa's current CORE One family listing explicitly centers active chamber temperature control. That creates a clearer buying argument when repeat nylon parts are already exposing temperature-stability and warping risk. It does not guarantee that every nylon grade or geometry will print successfully.
Serviceability has value after the first successful print
A repeat nylon process eventually becomes a maintenance process: nozzles wear, build surfaces age, sensors need checks, profiles change, and parts need requalification after hardware changes. Buyers who want published hardware information, replaceable parts, and more owner control may prefer the Prusa branch even when both machines can produce the first acceptable sample.
The purchase can be justified by process ownership
The CORE One case is strongest when someone will own drying, profile release, hardware changes, first-article approval, and maintenance records. Read the CORE One nylon buyer guide before treating the chamber headline as the complete answer.
Nylon requirements neither printer removes
Drying is part of the process, not an accessory afterthought
Wet nylon can create inconsistent extrusion, surface defects, stringing, and weak or unreliable results. A sealed tote can slow moisture pickup; it does not automatically restore a wet spool. Use the nylon drying versus storage guide to design that workflow before comparing printer features.
Filled nylon changes the wear-hardware question
Carbon- and glass-filled grades can be abrasive. Check the selected filament's nozzle recommendation and the exact hardware installed on the exact printer. Do not assume that an enclosed machine is automatically ready for every filled grade. The nylon-CF hardened-nozzle guide is the correct next branch when abrasion is the actual concern.
Ventilation and qualification still belong in the plan
An enclosure or filter is not permission to ignore indoor-air decisions. Follow the filament maker's safety guidance, plan ventilation for the space, and qualify a representative part. Chamber temperature, nozzle temperature, bed surface, adhesive, geometry, and drying all interact.
Compare accepted parts, not successful starts
Run the same representative nylon part through the candidate workflow and score more than whether the first layer sticks. Record dimensional stability, layer bonding, surface condition, support removal, scrap, operator intervention, and whether the result repeats after the spool has been stored and redried.
The relevant cost is:
printer and setup + drying and storage + wear hardware + failed qualification parts + operator time + maintenance - avoided outsourcing.
If recurring accepted output does not recover that cost, outsourcing the nylon edge case can be the better decision.
Three buyer scenarios
Mostly PETG fixtures with a few unfilled-nylon parts
Choose the P2S if the broad enclosed queue is the real reason for ownership. Prove the exact nylon grade and keep drying discipline separate from the printer decision.
Repeat nylon or filled-nylon production with an assigned operator
Lean toward the CORE One when the current machine/version, chamber behavior, wear hardware, and service plan all match the qualified job. The operator and release process are as important as the printer.
A handful of critical nylon parts each quarter
Price outside production before buying either machine around the exception. The printer-versus-service guide is the honest next step when finished parts matter more than owning the process.
Final recommendation
Buy the Bambu Lab P2S when the ten-job audit shows a broad everyday enclosed queue and only occasional nylon. Buy the Prusa CORE One when repeat nylon work makes controlled chamber behavior, repair access, and documented process ownership more valuable than the broader convenience-first default.
Confirm the exact CORE One generation and the exact nylon grade before ordering. If the workload cannot support a drying plan, a qualified profile, a representative proof part, and repeat demand, neither printer has earned a nylon-first purchase.
Common questions
Which is better for recurring nylon: P2S or CORE One+?
The current CORE One+ has the clearer nylon-first case when repeat jobs use its listed 55 degrees C chamber and you value repair access and long-term serviceability. The P2S is the cleaner pick when nylon is occasional and most work stays in easier materials.
Which printer has the larger build volume?
The P2S is listed at 256 x 256 x 256 mm, while the current CORE One+ is listed at 250 x 220 x 270 mm. P2S has more nominal X-Y area; CORE One+ has 14 mm more Z height. For nylon, chamber behavior, drying, and repeatability usually matter more than that modest envelope difference.
Do both printers need a filament dryer for nylon?
Plan on active drying and sealed storage based on the filament maker's instructions. Nylon can absorb moisture quickly, and an enclosed printer cannot reverse a wet spool. Use the nylon drying guide before qualifying the printer.
Is the Prusa CORE One automatically better for every nylon?
No. Its chamber and ownership posture can make the repeat-nylon case easier to defend, but the filament grade, nozzle, drying, profile, geometry, and qualification process still decide the result.
Can the P2S make sense for nylon?
Yes, especially when nylon is occasional and the broader PLA, PETG, TPU, and enclosed functional queue is the main reason to buy. Prove the exact job rather than relying on the material name alone.
Does nylon-CF change the winner?
It can. Filled nylon adds abrasion and sometimes different process demands. Verify both printers' installed hardware and the filament maker's requirements before treating a general nylon comparison as a nylon-CF approval.
Is the current Prusa product still called CORE One?
Prusa's current retail listing is CORE One+. Buyers evaluating an original CORE One or a used machine should confirm which specifications and upgrades actually apply to that unit.
Does the CORE One+ heated chamber guarantee good nylon parts?
No. Its listed 55 C chamber is a meaningful process-control advantage, not approval for every nylon. Drying, the exact grade, nozzle, profile, geometry, ventilation, and representative-part testing still decide the result.
Which printer has the larger build area?
The P2S lists 256 x 256 mm in X-Y versus 250 x 220 mm for the CORE One+, or about 19% more nominal plate area. The CORE One+ lists 270 mm of Z versus 256 mm for the P2S. Supports, brim, purge structures, and safe-edge margins reduce practical use.
Does nylon-CF change the winner?
It can. Filled nylon adds abrasive-wear and nozzle-diameter requirements that unfilled nylon may not share. The P2S lists hardened-steel extrusion hardware; Prusa says to consider a hardened nozzle for abrasive engineering materials. Follow the exact filament maker's guidance on either printer.
