| Property | Formlabs Form 4LRESIN | Prusa CORE One+ (Gen 2) INDXTOOLCHANGER |
|---|---|---|
| Identity | ||
| Brand | Formlabs | Prusa Research |
| Class | RESIN | TOOLCHANGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Formlabs Form 4L[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 documented | 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][2] |
| Street price (USD; dated snapshot per entry) | Not documented | $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) | Same Low Force Display engine as the Form 4 but a different machine on every physical figure: 353 x 196 x 350 mm vs 200 x 125 x 210, 46 um vs 50 um pixels, 58.5 kg vs 18.3 kg, 900 W vs 480 W, two resin cartridges vs one. Formlabs lists Basic, Premium and Complete packages, whose prices are not printer-only prices, and no printer-only USD figure was found on a live listing[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[3][2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 353 x 196 x 350 mm (Formlabs quotes 24.2 litres)[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) | 664 x 528 x 794 mm[1] | 415 x 444 x 555 mm - shared CORE One+ (Gen 2) figure[3] |
| Net weight (kg) | 58.5 kg[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Enclosed cabinet with a UV-blocking cover. Operating temperature 18-28 C[1] | Fully enclosed with active chamber heating up to 55 C (shared CORE One+ platform)[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Masked stereolithography (MSLA) with the Low Force Display engine; straight-lift peel[1] | CoreXY with a multi-tool head-changing system (INDX); Prusa's comparison table gives CoreXY for the CORE One family[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Nextruder direct drive, 10:1 planetary gearbox (shared platform)[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 290 C claimed max nozzle temperature, 400 C with the optional HT hotend (shared platform)[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | Not documented | 120 C max heatbed temperature (shared platform)[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Load-cell sensor, fully automatic first-layer calibration (shared platform)[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament sensors fitted (two on the CORE One+ platform)[3] |
| Multi-material/multi-color capability or official upgrade path | Not documented | INDX gives up to eight filaments; the alternative MMU3 handles five through a single nozzle[3] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | Custom 32-bit xBuddy board with STM32 (shared platform)[3] |
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 9 A, 50/60 Hz, 900 W[1] | Not documented |
| Total rated power draw | 900 W[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Proprietary; print preparation is PreForm[1] | 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] |
| 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)[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Dual-band Wi-Fi, Gigabit Ethernet, USB-C 2.0[1] | Ethernet and Wi-Fi, USB drive (shared platform)[3] |
| Materials Support | ||
| Officially supported filament list | Formlabs resin range as for the Form 4; biocompatible materials require a B-series machine[1] | PLA, PETG, Flex, PVA, PC, PP, CPE, PVB; ABS, ASA, HIPS and PA as advanced materials in the heated chamber (shared platform)[3] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 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] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | XY dimensional tolerance +/-0.15% — a manufacturer specification[1] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Low Force Display masking LCD with a 46 um pixel size. Formlabs does not publish the screen diagonal or pixel count[1] | Not documented |
| Light source | Backlight unit with uniform-wavelength LEDs behind collimating lenses, with integrated cooling[1] | Not documented |
| Layer height range | 25-200 um[1] | Not documented |
| Resin vat & feeding | Two next-generation resin cartridges. No vat capacity published[1] | 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.
