| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Original Prusa XL+, Dual-Head variant ("Prusa XL+ Dual-Head" in the e-shop variant data)[1] | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[2][3] |
| Release date (announcement and actual shipping) | The XL+ refresh was announced on 13 August 2026, on sale immediately in all toolhead configurations, with assembled printers shipping later in August 2026 and upgrade kits for existing XL owners from around the end of August. The original Original Prusa XL predates it[4] | Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[5] |
| Street price (USD; dated snapshot per entry) | $2,768.52 on prusa3d.com, Aug 2026 (lowest listed price for the Dual-Head variant; the 2-toolhead Enclosure bundle starts at $3,128.70)[1] | $649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | One of three XL+ configurations - Single-Tool $2,128.70, Dual-Head $2,768.52, Five-Head $3,610.18 (Aug 2026). The frame, bed, electronics and 360 mm cube build volume are identical across all three; only the toolhead count, the price and the achievable multi-material workflow change. Toolheads can be added later[1][6] | Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[3][2] |
| Market position: superseded? successor announced? | Not documented | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[7][8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 360 x 360 x 360 mm, which Prusa states as 46.7 litres[1] | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[2][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | About 700 x 900 x 720 mm (Prusa's own figure is approximate)[1] | 505 x 487 x 550 mm[5] |
| Net weight (kg) | About 30 kg[1] | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] |
| Frame construction & material | Aluminium extrusions and steel sheets (Prusa's comparison table for the XL)[9] | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame. The Enclosure for Prusa XL+ is an optional add-on; Prusa says the printer is ready for chamber temperatures up to 60 C, that the new better-sealed enclosure reaches around 50 C on the printer's own waste heat, and that 60 C needs an upcoming chamber heater for which no shipping date has been given[1][4] | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[2][5] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[2][5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY with 1.5 mm GT belts, Input Shaper and Phase Stepping[1] | CoreXY[5] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Dual independent Z motors on 10 mm linear shafts and screws[2] |
| Belts (type, width, e.g. Gates?) | 1.5 mm GT belts[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 600 mm/s (manufacturer claim, tool-head maximum)[5] |
| Max acceleration (claimed, mm/s²) | Not documented | <=20,000 mm/s2 (manufacturer claim)[5] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Input Shaper and Phase Stepping[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Nextruder direct drive; each toolhead carries its own extruder, hotend, nozzle and filament[1] | Direct drive with hardened steel dual gears, 1.75 mm filament[2][5] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Quick-swap nozzles - 0.25 mm for detail, 0.6/0.8 mm for speed, hardened steel for abrasives, high-flow CHT for throughput; toolheads ship with high-flow nozzles[1] | Second-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[2][5] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 290 C claimed max nozzle temperature[1] | <=370 °C claimed. No firmware max_temp verified for this model[2][5] |
| Heater cartridge power (W) | Not documented | 80 W hotend heater (manufacturer figure)[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | Conflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[2][5] |
| Bed surface (material, texture, coating), single/double-sided | Segmented heatbed of 16 individually controlled tiles across the 360 x 360 mm surface, so only the tiles under the part are powered; removable double-sided satin print sheet supplied[1] | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[2][5] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Load-cell sensor - the nozzle is the probe, which Prusa says automatically accounts for nozzle changes, surface textures and thermal expansion and removes manual Z-offsets. Toolhead-to-toolhead alignment on the XL+ uses a separate permanently mounted eddy-current Tool Offset Sensor, replacing the removable mechanical pin used on the original XL[1][4] | Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[2][5] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament sensors fitted; Prusa's comparison table lists two filament sensors for the XL[9] | Filament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[5] |
| Multi-material/multi-color capability or official upgrade path | Two independent toolheads with automatic tool changing - two materials or two nozzle sizes in one job, with no purge tower waste between materials because each head keeps its own nozzle[1] | QIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[2][3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | 360-degree part cooling on each toolhead, new on the XL+ and matching the MK4S and CORE One arrangement; Prusa states it delivers more airflow and distributes it more evenly around the nozzle. Additional fans and heatsinks cool the electronics. Fan sizes are not published[1][4] | Auxiliary part-cooling fan plus a chamber circulation fan; fan sizes and duct design not published[5] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Custom 32-bit xBuddy electronics with STM32 (Prusa's comparison table for the XL)[9] | Not documented |
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 50/60 Hz[5] |
| Total rated power draw | Not documented | 450 W plus 400 W for chamber heating (rated)[5] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Open-source firmware - Prusa states "Firmware: Open-source; ships with the full current Prusa feature set", and the XL is covered by the prusa3d/Prusa-Firmware-Buddy source tree[1][10] | Klipper v0.12, described by QIDI as open source. Fork details and current release not published on the product page[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch 65k-colour screen with touch control (Prusa's comparison table for the XL)[9] | 5-inch touchscreen, 800 x 480[2][5] |
| On-device UI capabilities (model preview, per-object controls, etc.) | On-device touch UI; Prusa Connect and the Prusa mobile app are optional - Prusa states the machine is fully offline capable[9][1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Ethernet, optional Wi-Fi; USB drive for print files. Prusa Connect optional and fully offline operation supported[1][9] | Wi-Fi 2.4 GHz, Ethernet, USB[2][5] |
| Cloud service & phone app; LAN-only mode possible? | Not documented | Mobile and computer control, remote cloud or LAN-only operation[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in low-frame-rate camera, up to 1080p, timelapse supported[2][5] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Not documented | QIDI claims about 10 minutes from unbox to printing[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery listed; mechanism not published[5] |
| Materials Support | ||
| Officially supported filament list | PLA, PETG, ASA, ABS, PC, PA (nylon), TPU, PVA, HIPS, PP, CPE, PVB and carbon-fibre composites. Prusa states an open material policy - any brand of 1.75 mm filament, no chips and no subscriptions[1] | PLA, ABS, ASA, PETG, TPU, PA, PC, PA-CF/GF, PET-CF/GF, PPA-CF/GF, PPS-CF and other CF/GF-filled polymers[2][5] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[11][10] | 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[12][9] | 1-year coverage, 14-day no-reason return, 30-day price protection[2] |
