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 X-Smart 3, listed in QIDI navigation as X-Smart3[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 by QIDI on the pages checked (Aug 2026)[3][4]
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]$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[4]
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]Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[3][6][7]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 220 x 270 mm - the CORE One+ (Gen 2) figure from the shared product page; Prusa does not publish a separate INDX build volume[2]175 x 180 x 170 mm advertised[3][4]
Machine footprint (mm) & clearance needed (cable/spool overhang)415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[2]370 x 362 x 397 mm[3]

Mesh grid size (probe point count — firmware evidence)Not documented16 points (QIDI's US page). Not verified against firmware[4]
Filament Handling & Detection
Filament runout sensor (type, location)Filament sensors fitted (two on the CORE One+ platform)[2]Filament detection fitted; type and location not published[3]
Multi-material/multi-color capability or official upgrade pathINDX gives up to eight filaments; the alternative MMU3 handles five through a single nozzle[2]Not documented
Electronics & Power

Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[10][9]1-year coverage (QIDI standard store terms)[11]

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.
