| Property | Original Prusa MINI+BEDSLINGER | QIDI i-FastIDEX |
|---|---|---|
| Identity | ||
| Brand | Prusa Research | QIDI |
| Class | BEDSLINGER | IDEX |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Original Prusa MINI+ Semi-assembled 3D Printer[1] | QIDI Tech i-Fast, also written iFast and "I-Fast"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published on the listings checked (Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | $508.33 on prusa3d.com, Aug 2026[4] | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[3][2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Sold semi-assembled and, historically, as a kit; also offered in an Enclosure Bundle. Distinguish from the larger i3-family machines - the MINI+ is Bowden-fed with 2209 drivers, a 280 C nozzle ceiling and a 100 C bed, all lower than the MK3S+/MK4S. Note that Prusa's own MINI+ page carries an "Awards & Press Reviews" paragraph that is entirely about the MK3S, not the MINI+[1][5] | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[3][2] |
| Market position: superseded? successor announced? | Not documented | Discontinued; QIDI's current line is the Q, Plus and Max series[3][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 180 mm (manufacturer figure)[1] | 330 x 250 x 320 mm advertised[2][3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 380 x 330 x 380 mm (X x Y x Z), stated without the spool holder and external PSU - the external PSU brick needs additional desk space[1] | 710 x 510 x 670 mm[3] |
| Net weight (kg) | 4.5 kg without spool holder and external PSU[1] | 33 kg net[3] |
| Frame construction & material | Not documented | Fully assembled enclosed metal-frame machine[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame; sold with an optional Enclosure bundle[1] | Fully enclosed with a heated chamber[2][3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Not documented | Dual independent extruders in an enclosed Cartesian gantry[2][3] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Trinamic 2209 silent stepper drivers, with sensorless homing on the X and Y axes[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden extruder with 3:1 gearing - the only current Prusa FFF machine that is not direct drive[1] | Direct-drive, two extruders. MK10-style nozzle[2][3] |
| Gear ratio & drive gear material | 3:1 extruder gearing[1] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 280 C claimed max nozzle temperature - lower than the 290-300 C of the i3-family machines[1] | 350 °C on the high-temperature extruder assembly[2][3] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm nozzle diameter[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 C max heatbed temperature[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Removable magnetic steel sheets in several surface finishes; heatbed with cold-corner compensation[1] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | SuperPINDA inductive probe with no temperature drift, driving automatic mesh bed levelling[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Custom 32-bit board of Prusa's Buddy family; the MINI/MINI+ is covered by the same Prusa-Firmware-Buddy source tree as the MK4, XL and CORE One. The exact board revision is not given on the product page[1][7] | Not documented |
| Input voltage (110/220 V, switch or auto) | Not documented | 110-220 V[3] |
| Total rated power draw | Not documented | 700 W rated[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[7][8] | Not documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 2.8-inch 65k-colour graphic screen with G-code preview[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | On-device colour UI with G-code preview; remote print management through Prusa Connect[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB port, RJ-45 Ethernet, optional ESP Wi-Fi module (sold separately); compatible with Prusa Connect[1] | Wi-Fi, LAN, USB flash drive[2][3] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Semi-assembled: Prusa ships it in a small number of pre-built sections; also historically sold as a full kit[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, Woodfill and other filled materials (Prusa's own list; the 100 C bed and open frame are the practical limit for ABS/ASA)[1] | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[3] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Three thermistors and fan RPM sensors are fitted, and the firmware is open-source and auditable (Prusa-Firmware-Buddy); Prusa does not describe the thermal-runaway implementation on the product page[1][7] | Not documented |
| 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[9][8] | 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.
