| Property | QIDI Q1 ProCOREXY | Rat Rig V-Core 4.1COREXY |
|---|---|---|
| Identity | ||
| Brand | QIDI | Rat Rig |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Q1 Pro, listed by QIDI as "Q1 Pro 3D Printer". QIDI traded as Qidi Tech until end-2024[1] | Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[2] |
| Release date (announcement and actual shipping) | Not stated on QIDI's own product page; the page now carries a discontinuation notice instead of a launch date (checked Aug 2026)[1][3] | Not documented |
| Street price (USD; dated snapshot per entry) | $499.00 on both qidi3d.com and us.qidi3d.com, checked Aug 2026 — but the listing is marked Sold Out and the page states "This model has been discontinued". qidi3d.com shows it against a $599.00 regular price; the US store shows compare-at $499.00[1][3] | Not documented |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Succeeded by the QIDI Q2, which QIDI's own comparison on the Q1 Pro page distinguishes as 270x270x256 mm (vs 245x245x240), 370 °C hotend (vs 350 °C) and 65 °C chamber (vs 60 °C). Do not read Q2 figures onto the Q1 Pro[1][3] | Three sizes, all at the same base-kit price. Acceleration is the size-dependent figure and the one most often mis-quoted: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm. IDEX is a configuration option and changes the usable area per toolhead (copy mode 150x150x300 at the 300 size, mirror mode 95x95x300). Base kit excludes electronics. Rat Rig prices the base kit only in EUR (EUR 873.90 on sale from EUR 971.00, Aug 2026); no USD list price is published, so no USD street price is recorded here[2] |
| Market position: superseded? successor announced? | Discontinued and out of production; QIDI states spare parts and support for existing owners remain available. Replaced by the Q2[1][3] | Current revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 245 x 245 x 240 mm advertised (QIDI). No independently measured usable envelope found[1][4] | 300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 477 x 467 x 489 mm machine dimensions (QIDI)[1][4] | 623.2 x 583 x 785 mm (300); 723.2 x 683 x 885 mm (400); 823.2 x 783 x 985 mm (500). Sortable value is the 300 mm kit[2] |
| Net weight (kg) | 17 kg net, 20.3 kg gross (QIDI). 3DJake lists the 20.3 kg figure as gross weight[1][4] | Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[2] |
| Frame construction & material | Metal CoreXY motion frame with panelled enclosure; QIDI publishes no frame-material breakdown for this model[1] | 30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with independent chamber heating to 60 °C; QIDI does not publish the panel materials for this model[1][4] | Open frame in the base kit[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 60 °C, actively heated (manufacturer claim — this is a heater setpoint, not a measured passive figure)[1][4] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[4] | CoreXY; Hybrid CoreXY and IDEX are configuration options[2] |
| X-axis guide type (rods / linear rails / V-wheels; size) | 10 mm linear steel rods with automatically tensioned belt (manufacturer description)[4] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Independent dual Z lead-screw motors[4] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s, worded by QIDI as maximum tool-head speed (manufacturer claim, not a sustained printing speed)[1][4] | Not documented |
| Max acceleration (claimed, mm/s²) | <=20,000 mm/s2 (manufacturer claim)[1][4] | Size-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive extruder with hardened steel gears[1][4] | Full-metal skeleton toolhead, new in the 4.1[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Tri-metal hotend with a ceramic heater plate and a bimetal nozzle, 0.4 mm standard[1][4] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | <=350 °C claimed. No firmware max_temp verified for this model[1][4] | 350 °C maximum nozzle temperature (manufacturer claim)[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm hardened steel and 0.6 mm included[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | <=120 °C claimed. No firmware limit verified for this model[1][4] | 120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[2] |
| Bed surface (material, texture, coating), single/double-sided | Double-sided textured PEI plate on an aluminium substrate bed[1][4] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic levelling; QIDI markets it as "hands-free automatic levelling" with dual sensors, without naming the probe technology[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament run-out sensor fitted; QIDI also lists filament tangle detection without describing the mechanism[4] | Not documented |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Auxiliary part-cooling fan plus a chamber circulation fan (fan count and duct design not published)[4] | Improved part cooling, listed by Rat Rig as one of the 4.1 changes[2] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 50/60 Hz[4] | Not documented |
| Total rated power draw | 350 W plus 300 W for chamber heating (rated)[1][4] | Not documented |

| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Built-in camera, up to 1080p, timelapse supported. Framerate not published[1][4] | Not documented |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Ships fully assembled[1] | Self-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Power-loss recovery listed as a feature; mechanism not published[4] | Not documented |
| Materials Support | ||
| Officially supported filament list | QIDI lists compatibility with common filaments; storage 32 GB eMMC. No per-material list published on the current page beyond the general claim[1] | PLA, PETG, ABS, ASA, TPU, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[2] |

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.
