Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Formlabs Form 4 3D Printer[1][2]Prusa CORE One+ (Gen 2) INDX, listed as "INDX 4-Tool" and "INDX 8-Tool" variants and as an "INDX 8-Tool Assembly kit"[3][4]
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[5][3]
Street price (USD; dated snapshot per entry)Starting at $2,625.00 at GoEngineer, in stock, checked Aug 2026. Formlabs sells the printer as part of packages (Form 4 Complete Package etc.), so package prices are much higher than the printer-only figure[2]$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[3][4]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Three machines share this platform and are constantly conflated. Form 4: 200 x 125 x 210 mm, 50 um pixels, 18.3 kg, 480 W, one resin cartridge, NOT biocompatible. Form 4B: identical hardware but validated for 38 Formlabs materials including 15 biocompatible. Form 4L: 353 x 196 x 350 mm, 46 um pixels, 58.5 kg, 900 W, two cartridges[1]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[4][3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable200 x 125 x 210 mm (Formlabs quotes 5.25 litres)[1][2]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[4]
Machine footprint (mm) & clearance needed (cable/spool overhang)398 x 367 x 554 mm[1][2]415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[4]
Net weight (kg)18.3 kg[1][2]Not documented
Enclosure: open / enclosed; panel material; door/lidEnclosed cabinet with a hinged UV-blocking cover. Operating temperature 18-28 C[1]Fully enclosed with active chamber heating up to 55 C (shared CORE One+ platform)[4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Masked stereolithography (MSLA). Formlabs brands the engine Low Force Display; straight-lift peel[1][2]CoreXY with a multi-tool head-changing system (INDX); Prusa's comparison table gives CoreXY for the CORE One family[4]
Extruder
Type (direct drive / bowden) & design nameNot documentedNextruder direct drive, 10:1 planetary gearbox (shared platform)[4]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented290 C claimed max nozzle temperature, 400 C with the optional HT hotend (shared platform)[4]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented120 C max heatbed temperature (shared platform)[4]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedLoad-cell sensor, fully automatic first-layer calibration (shared platform)[4]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament sensors fitted (two on the CORE One+ platform)[4]
Multi-material/multi-color capability or official upgrade pathNot documentedINDX gives up to eight filaments; the alternative MMU3 handles five through a single nozzle[4]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedCustom 32-bit xBuddy board with STM32 (shared platform)[4]
Input voltage (110/220 V, switch or auto)100-240 VAC, 4.8 A, 50/60 Hz, 480 W[1]Not documented
Total rated power draw480 W[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Proprietary. Print preparation is PreForm; fleet management is Formlabs Dashboard[2]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[6][7]
Connectivity, UI & Camera
Display: size, type, touch?7-inch interactive touchscreen, 1280 x 800 (control panel — not the masking LCD, see W1)[1]3.5-inch 65k-colour touch screen (shared platform)[4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveDual-band Wi-Fi, Gigabit Ethernet (1000 Mbit), USB-C 2.0[1][2]Ethernet and Wi-Fi, USB drive (shared platform)[4]
Materials Support
Officially supported filament listFormlabs resins across rigid, tough, general purpose, flame retardant, silicone, elastic, ceramic and castable families. Biocompatible resins require the Form 4B, not the Form 4[1]PLA, PETG, Flex, PVA, PC, PP, CPE, PVB; ABS, ASA, HIPS and PA as advanced materials in the heated chamber (shared platform)[4]
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[8][7]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)XY dimensional tolerance +/-0.15% — a manufacturer specification, not an independent measurement[1][2]Not documented
Resin & MSLA
Masking LCDLow Force Display masking LCD with a 50 um pixel size and pre-tuned anti-aliasing. Formlabs does not publish the screen diagonal or pixel count[1][2]Not documented
Light sourceBacklight unit with 60 uniform-wavelength high-power LEDs behind collimating lenses, with integrated cooling[1][2]Not documented
Vertical print speedmm/hMaximum 100 mm/h; average 40 mm/h at a 100 um layer height (manufacturer figures — GoEngineer publishes both, which is unusually explicit about the basis). Formlabs separately claims most prints finish in under 2 hours[2][1]Not documented
Layer height range25-200 um per Formlabs' own tech-spec page; GoEngineer's listing for the same machine says 25-300 um. Unresolved[1][2]Not documented
Resin vat & feedingSingle next-generation resin cartridge; Formlabs claims 5-10x faster filling and 63% less waste. Resin tank rated for 75,000+ layers with any Formlabs material. No vat capacity published[1][2]Not documented

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.
