Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Flashforge Guider 3 Ultra; the FlashForge spec table gives the machine name as "Guider 3 Ultra"[1]Prusa CORE One+ (Gen 2) INDX, listed as "INDX 4-Tool" and "INDX 8-Tool" variants and as an "INDX 8-Tool Assembly kit"[2][3]
Release date (announcement and actual shipping)Not documentedAnnounced 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][2]
Street price (USD; dated snapshot per entry)$2,399.00 against a $3,499.00 regular price on flashforge.com, but the listing checked is the refurbished SKU and is marked Sold out (Aug 2026)[1]$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[2][3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Top of the Guider 3 series. Build size depends on which head is used: 330 x 330 x 600 mm with one extruder, 300 x 330 x 600 mm with both. Siblings Guider 3 (300x250x340) and Guider 3 Plus (350x350x600) are both single-extruder. A refurbished SKU exists alongside the new machine, so check which one a price refers to[1][5][6]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[3][2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable330 x 330 x 600 mm with a single extruder; 300 x 330 x 600 mm when both extruders are in use[1]250 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[3]
Machine footprint (mm) & clearance needed (cable/spool overhang)635 x 550 x 1070 mm; packaging 775 x 690 x 1235 mm[1]415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[3]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY with two extruders, per a third-party buyer's guide. FlashForge's own spec table does not state the kinematics[7][1]CoreXY with a multi-tool head-changing system (INDX); Prusa's comparison table gives CoreXY for the CORE One family[3]

Filament Handling & Detection
Filament runout sensor (type, location)Filament run-out reminder[1]Filament sensors fitted (two on the CORE One+ platform)[3]

Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)Not documented2-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]

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.
