|---|---|---|
| Identity | ||
| Brand | Bambu Lab | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Bambu Lab P2S; spec sheet header "P2S Spec Sheet"[1] | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[2][4] |
| Street price (USD; dated snapshot per entry) | From $549.00 on the Bambu Lab US store, Aug 2026; the product page shows $749.00 with the P2S Combo variant selected[5][6] | $1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[1][7] | Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[2][4] |
| Market position: superseded? successor announced? | Current model, marketed by Bambu as "The Classic Evolves" - the direct replacement for the P1S, which is still sold below it[5] | Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[2][4] |

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.
