Buy the Bambu Lab X2D for nylon when the 65 °C active chamber and second nozzle solve recurring warping, support-interface, or changeover work. Buy the Prusa CORE One / current CORE One+ when a 55 °C enclosed chamber is enough and you value a more focused, serviceable single-tool workflow.
Neither printer makes nylon automatic. Drying, the exact nylon grade, nozzle wear, bed surface, ventilation, geometry, and a qualified profile still decide whether parts are repeatable. The X2D has the stronger thermal and dual-nozzle ceiling; the CORE One is the cleaner ownership choice when that extra ceiling would sit unused.
The nylon decision in 30 seconds
Buy the X2D if: recurring nylon jobs need the manufacturer-listed 65 °C active chamber, a second nozzle has a proven support or material-change role, and 256 × 256 × 260 mm covers the queue.
Buy the current CORE One+ Gen 2 if: recurring parts fit 250 × 220 × 270 mm, the 55 °C chamber class covers the qualified process, and maintainable single-tool ownership matters more than X2D's included dual-nozzle range. Treat Prusa's advertised INDX path as a separately verified upgrade, not included capability.
Buy neither yet if: the spool is not being dried, the installed nozzle has not been checked for the exact filled nylon, or nylon appears in only one speculative future job.

Current-model note: retail now says CORE One+ Gen 2
Prusa's current product route presents CORE One+ (Gen 2), while this canonical and existing search demand use CORE One. The current listing keeps the 250 × 220 × 270 mm build volume and 55 °C chamber class, lists a high-flow brass CHT 0.4 mm nozzle with a 290 °C standard maximum, and advertises INDX compatibility plus up to eight colors with the upgrade.
That does not turn every original CORE One into a Gen 2 machine or make INDX part of the base printer. For a new or used Prusa, verify the exact generation, installed nozzle, HT hardware if relevant, INDX availability and package, firmware, profiles, warranty, and upgrade state. For X2D, confirm the two installed nozzle paths, material system, accessories, voltage, and current bundle.
Where the X2D wins for nylon
The X2D wins on manufacturer-listed chamber headroom. Bambu pairs a 300 °C nozzle with a 65 °C actively heated chamber and explicitly names nylon among the engineering-filament use cases. Prusa lists a 55 °C chamber for CORE One+, so the X2D has a ten-degree published advantage. That does not approve every nylon automatically, but it gives demanding geometries more thermal room before the machine becomes the obvious constraint.
The second win is architecture. Two nozzles can matter when a qualified support-interface material reduces removal damage, when separate nozzle states shorten repeated changes, or when one nozzle is reserved for a recurring job family. Prove compatibility first: nylon and the support material must coexist at workable temperatures and adhesion conditions. The X2D support-material guide handles that narrower question.
Read the X2D review and X2D nylon buyer guide if the hotter dual-nozzle branch already fits the work.
Where the CORE One wins for nylon
The CORE One+ Gen 2 wins when the nylon process is serious but still works cleanly as a single-tool cell. Prusa's current page explicitly lists PA (nylon), gives 260–280 °C nozzle and 80–90 °C bed guidance, calls out moisture sensitivity, and says the heated chamber helps prevent warping. That is a useful published process boundary, not a promise that every geometry or blend will pass.
Its buying case is proportion. The current standard nozzle is a high-flow brass CHT 0.4 mm part, so buyers planning PA-CF or PA-GF should not confuse the printer's 290 °C standard temperature ceiling—or the separately advertised 400 °C HT path—with abrasion readiness. Prusa explicitly suggests a hardened nozzle for abrasive engineering materials. If one wear-ready nozzle, a dry spool, and a qualified profile cover the queue, X2D's second nozzle and hotter chamber may not change accepted output. On the Bambu side, use the X2D hardened-nozzle guide to verify the matching wear-path question.
Use the CORE One review, CORE One nylon guide, and CORE One hardened-nozzle guide before treating the ownership-first branch as fully configured.
Run a five-part nylon qualification before buying
- Name the exact material. Unfilled PA, PA-CF, PA-GF, and vendor-specific copolymers do not share one nozzle, temperature, drying, or wear requirement.
- Dry and contain it. Record dryer temperature and time from the filament maker, then feed from dry storage when the spool format and routing allow it. A chamber cannot repair a wet spool.
- Check the supported geometry. Include orientation, brims, supports, shrinkage, safe edge clearance, and the inspection dimensions that decide whether the part passes.
- Verify the wear path. Confirm both the nozzle and any upstream components exposed to abrasive filler. “Can reach the temperature” is not the same as “ready for filled nylon.”
- Run a representative acceptance part. Check warping, layer bonding, support removal, surface damage, hole size, loaded features, and repeatability across more than one cycle.
If drying or enclosure is still the unresolved gate, read whether nylon needs a dryer and whether nylon needs an enclosure before assigning the failure to either printer.
When the second nozzle is actually worth paying for
Give the X2D credit only when the second nozzle changes a repeated task. Count support-interface labor, nozzle swaps, purge, setup, cleanup, rejected surfaces, operator attention, and delivery risk across ten representative nylon jobs. A support strategy that saves twenty minutes on one demonstration is not the same as a workflow that saves hours every week.
Keep the CORE One+ Gen 2 ahead when most jobs use one nozzle, support removal is already acceptable, and the 55 °C chamber passes the target geometry. Put the X2D ahead when multiple jobs repeatedly need its hotter chamber or when its included two-nozzle hardware reduces accepted-part labor.
Do not award Prusa the INDX benefit from a product-page headline alone. Get the exact upgrade price and availability, confirm the supported nylon and interface-material combination, and compare loaded-tool recovery, purge, change time, support quality, and maintenance against X2D's included dual-nozzle architecture. If that evidence is vague, the broader X2D vs CORE One comparison is the better route.
Price the complete nylon cell
Do not compare printer prices alone. Add the exact nozzle or nozzles, build surface, dryer, dry feed path, sealed storage, spare parts, ventilation, qualification material, failed parts, cleanup, inspection tools, and operator time. If INDX is part of the Prusa case, add its exact current package, supported tool count, required hardware, and qualification work instead of pricing an advertised upgrade as though it were included. Use current quotes rather than freezing a temporary storefront price into the decision.
The CORE One can deliver the better return when a hardened single-tool setup produces accepted parts with less paid capability sitting idle. The X2D can deliver the better return when its hotter chamber avoids repeated geometry failures or its second nozzle cuts support labor and rejected surfaces. Convert those gains into hours, accepted parts, and delivery risk over six or twelve months.
Also price the cost of choosing too little machine. A lower purchase total is not a saving if repeated warping, manual support cleanup, or outside production overwhelms it. But extra chamber headroom and a second nozzle are not assets until a representative queue uses them.
Three buyer scenarios
Functional parts in unfilled nylon
Start with the CORE One when parts fit, the official PA temperature range covers the filament, and one nozzle handles the queue. Move to X2D when repeated geometry proves the extra chamber headroom matters.
PA-CF fixtures with difficult supports
Confirm the exact abrasive-ready path on both machines. Favor X2D only when its second nozzle supports a qualified interface workflow or materially reduces changeover; otherwise a hardened single-tool setup may be the cleaner cell.
One occasional customer nylon job
Do not let a rare material choose the whole printer. Compare redesign, another material, or outside production with the cost of drying, ventilation, qualification, spares, and operator learning.
When one nylon job should not choose the whole printer
For an occasional customer part or a batch with a delivery commitment, use the printer-versus-service guide before buying a printer, dryer, wear hardware, ventilation, and qualification stock around one job.
- Material or repeatability still unsettled: use the small-batch service guide to define quantity, nylon grade, support-interface needs, finish, tolerance, inspection, and timing. Ask JC Print Farm while the production route still needs operator review.
- File and acceptance criteria ready: run the quote-prep checklist, then request a quote with the exact scope.
Final recommendation
Choose the Bambu Lab X2D when nylon is part of a recurring higher-heat or dual-nozzle workflow. Its published 65 °C chamber, 300 °C nozzle, and two-nozzle architecture give it the stronger capability ceiling.
Choose the current Prusa CORE One+ Gen 2 when a qualified single-tool nylon process is enough. Its published PA guidance, 55 °C chamber, serviceable ownership, and explicit hardened-nozzle checkpoint make it the more proportionate default. Count INDX only after the exact upgrade and nylon workflow beat X2D's included dual-nozzle path on real jobs.
Frequently asked questions
Which printer has the hotter chamber?
Bambu lists 65 °C active chamber heating for X2D. Prusa lists a 55 °C heated enclosed chamber for the current CORE One+ route.
Can both printers print nylon?
Both manufacturers position the machines for nylon or PA work. Success still depends on the exact grade, drying, nozzle and material-path readiness, geometry, bed surface, ventilation, profile, and acceptance test.
Do you need a hardened nozzle for nylon?
Not every unfilled nylon is abrasive, but carbon- and glass-filled grades commonly require wear-resistant hardware. Confirm the filament maker's guidance and the exact installed nozzle rather than assuming temperature capability proves abrasion readiness.
Does dual nozzle automatically make X2D better for nylon supports?
No. The second nozzle helps only when the chosen nylon and support material are thermally and mechanically compatible and the workflow reduces real cleanup or failure. Prusa's advertised INDX path is a separate upgrade decision; it should not be treated as included CORE One+ Gen 2 capability.

If this page is turning into a real next-step decision, start here
This X2D-versus-CORE-One nylon page lands better when it gives readers one serious recovery-dryer branch, one tougher Prusa-side nozzle lane, and one cheaper humidity-proof step instead of pretending nylon fit is only about the printer badge.
If the honest answer is that either printer only makes sense for nylon once opened spools can actually be recovered instead of merely stored: Creality Space Pi X4 is the cleaner first buy. It fits readers whose real blocker is serious wet-spool recovery, not one more round of printer shopping. The tighter on-site handoff is the Creality Space Pi X4 review.
If the CORE One side gets stronger because you expect the more serviceable Prusa lane to carry tougher nylon or abrasive blends longer: Diamondback Nextruder nozzle is the tighter hardware branch. It matches readers whose Prusa-side logic depends on a tougher long-run nozzle path too. The tighter on-site handoff is the Diamondback Nextruder review.
If you should first prove whether tote or shelf humidity is what keeps making nylon behave worse than the printer choice alone would explain: TempPro TempAir Bluetooth hygrometer is the cheaper truth-check. It fits readers who should measure before escalating the whole premium-printer story. The tighter on-site handoff is the ThermoPro TP357 review.
That keeps the monetization compact and useful: one heavier dryer, one harder-wear nozzle path, and one cheaper truth-check before nylon buyers keep blaming the machine for storage drift.
