| Property | Bambu Lab H2SCOREXY | Bambu Lab P2SCOREXY |
|---|---|---|
| Identity | ||
| Brand | Bambu Lab | Bambu Lab |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab H2S; spec sheet header "H2S & H2S Laser Edition Spec Sheet"[1] | Bambu Lab P2S; spec sheet header "P2S Spec Sheet"[2] |
| Street price (USD; dated snapshot per entry) | From $1,199.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $1,249.00[3] | From $549.00 on the Bambu Lab US store, Aug 2026; the product page shows $749.00 with the P2S Combo variant selected[3][4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Single-nozzle machine sharing the H2 body. H2S and H2S Laser Edition are covered by one spec sheet: the Laser Edition adds laser safety windows, the air-assist pump and the 3264x2448 BirdsEye camera, and a plain H2S can be upgraded with a Laser Upgrade Kit. Against the dual-nozzle H2D in the same 492x514x626 mm shell: 30 kg vs 31 kg, 340x320x340 mm single-nozzle volume vs 325x320x325 mm[1][5] | Two SKUs: P2S and P2S Combo (with the 2nd-generation AMS, which adds filament drying). Do not carry P1S figures across - the P2S differs on nearly every headline number: 600 vs 500 mm/s, 110 vs 100 C bed, hardened-steel vs stainless nozzle, 5-inch 854x480 touchscreen vs 2.7-inch monochrome, 14.9 vs 12.95 kg, 1920x1080 30 fps camera vs 1280x720 at 0.5 fps[2][6] |

| Max volumetric flow claimed (mm³/s) | 40 mm3/s standard-flow hotend, 65 mm3/s optional high-flow hotend; Bambu's test is a 250 mm round single-wall model in Bambu ABS at 280 C[1] | 40 mm3/s standard-flow hotend, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened-steel gears and a Bambu high-precision permanent-magnet synchronous extruder motor; built-in filament cutter[1] | Direct drive with hardened-steel extruder gears, driven by a Bambu Lab high-precision permanent-magnet synchronous motor rather than a plain stepper; built-in filament cutter[2] |

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
