| Property | Prusa CORE One+ (Gen 2) INDXTOOLCHANGER | QIDI Max4COREXY |
|---|---|---|
| Identity | ||
| Brand | Prusa Research | QIDI |
| Class | TOOLCHANGER | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Prusa CORE One+ (Gen 2) INDX, listed as "INDX 4-Tool" and "INDX 8-Tool" variants and as an "INDX 8-Tool Assembly kit"[1][2] | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[3][4] |
| Release date (announcement and actual shipping) | Announced as shipping on 20 August 2026 ("INDX, Shipping Has Started, Complete Printers Open for Orders"). Prusa's own front page in Aug 2026 announces "Prusa CORE One+ (Gen 2) INDX, Shipping Has Started, Complete Printers Open for Orders", with the assembled 8-tool machine quoted as shipping from 15 October and the kit from 29 October[5][1] | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[3][6] |
| Street price (USD; dated snapshot per entry) | $1,850.93 for the INDX 4-Tool and $2,082.41 for the INDX 8-Tool on prusa3d.com, Aug 2026; the 8-Tool assembly kit is $1,804.63. Camera and filtration bundles run to $2,152.78[1][2] | $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[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | INDX is a multi-tool option on the CORE One+ (Gen 2) product page rather than a separate printer, sold in 4-tool and 8-tool configurations, plus a CORE One/+ INDX conversion kit for existing machines. All of the body, hotend, bed and electronics figures below come from that shared CORE One+ (Gen 2) page and were not published separately for the INDX machine, so treat them as platform figures. Prusa also sells the unrelated MMU3, which multiplexes five filaments through one nozzle[2][1] | 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[3][6] |
| Market position: superseded? successor announced? | Not documented | Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[3][6] |

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.
