| Property | QIDI Plus4COREXY | Snapmaker J1sIDEX |
|---|---|---|
| Identity | ||
| Brand | QIDI | Snapmaker |
| Class | COREXY | IDEX |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[1][2] | Snapmaker J1S High Speed IDEX 3D Printer[3][4] |
| Release date (announcement and actual shipping) | Announced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[5] | Not documented |
| Street price (USD; dated snapshot per entry) | $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[1][2] | $1,399.00 at MatterHackers, listed as currently unavailable with a pre-order option quoting roughly 5 weeks, checked Aug 2026[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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)[2][1] | The J1s differs from the original J1 by an additional part-cooling fan. Usable volume depends on the print mode: 300 x 200 x 200 mm in default and backup modes, 160 x 200 x 200 in copy mode, 150 x 200 x 200 in mirror mode[3][4] |
| Market position: superseded? successor announced? | Superseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[6][7] | Not documented |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 305 x 305 x 280 mm advertised. No independently measured usable envelope found[1][5] | 300 x 200 x 200 mm in default and backup modes[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 505 x 487 x 550 mm[5] | 539 x 401 x 464 mm[3] |
| Net weight (kg) | 32 kg gross (3DJake). QIDI does not publish a net weight on the product page[5] | 25 kg net[3] |
| Frame construction & material | Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[1] | Aluminium-alloy frame with one-piece die casting and linear rails; Snapmaker quotes rail repeatability of +/-0.03 mm in X/Y and +/-0.02 mm in Z[4] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[1][5] | Not documented |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[1][5] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[5] | IDEX — two independently driven extruders[3][4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | Linear rails[4] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Dual independent Z motors on 10 mm linear shafts and screws[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s (manufacturer claim, tool-head maximum)[5] | 350 mm/s maximum (manufacturer claim)[4] |
| Max acceleration (claimed, mm/s²) | <=20,000 mm/s2 (manufacturer claim)[5] | 10,000 mm/s2 maximum (manufacturer claim)[4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive with hardened steel dual gears, 1.75 mm filament[1][5] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | 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[1][5] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | <=370 °C claimed. No firmware max_temp verified for this model[1][5] | 300 °C maximum (manufacturer claim)[3][4] |
| Heater cartridge power (W) | 80 W hotend heater (manufacturer figure)[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 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[1][5] | 100 °C maximum (manufacturer claim)[3] |
| Bed surface (material, texture, coating), single/double-sided | 6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[1][5] | Custom dual-sided PEI glass plate: glossy glass on one face, PEI coating on the other[3][4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Full-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[1][5] | 3-point bed levelling, which Snapmaker contrasts with 9-16 point systems; assisted calibration quoted at about 10 minutes[4] |

| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper v0.12, described by QIDI as open source. Fork details and current release not published on the product page[1] | Not named by Snapmaker; the supplied slicer is Luban, with third-party software supported[3] |

| Materials Support | ||
| Officially supported filament list | PLA, ABS, ASA, PETG, TPU, PA, PC, PA-CF/GF, PET-CF/GF, PPA-CF/GF, PPS-CF and other CF/GF-filled polymers[1][5] | PLA, ABS, HIPS, PC, TPU, TPE, PETG, ASA, PP, PVA, PA, PA-GF, PA-CF[3] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Less than 50 dBA claimed by the manufacturer. No independent measurement; distance and method not stated[3] |

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.
