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]UltiMaker Factor 4[3]
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[4][1]Announced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[3]
Launch MSRP (USD)Not documentedStarting at approximately $20,000[3]
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]Not documented
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]Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[3]
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]330 x 240 x 300 mm[3]

Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[5][6]Not documented

Materials Support
Officially supported filament listPLA, PETG, Flex, PVA, PC, PP, CPE, PVB; ABS, ASA, HIPS and PA as advanced materials in the heated chamber (shared platform)[2]UltiMaker-branded PPS CF, PLA, Tough PLA, Nylon, PETG, PET CF and PVA, plus validated third-party materials from BASF Forward AM, Kimya, Polymaker, LEHVOSS and Jabil[3]
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[7][6]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedDimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[3]

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.
