| Property | QIDI X-Plus 3COREXY | QIDI X-Smart 3COREXY |
|---|---|---|
| Identity | ||
| Brand | QIDI | QIDI |
| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI X-Plus 3, listed in QIDI navigation as X-Plus3[1][2] | QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[3][4] |
| Release date (announcement and actual shipping) | Not published by QIDI on the pages checked (Aug 2026)[1][2] | Not published by QIDI on the pages checked (Aug 2026)[3][4] |
| Street price (USD; dated snapshot per entry) | $699 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026. 3DJake lists the model as sold out[2][1] | $399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Two headline-speed figures circulate for this model: QIDI's own US page says 600 mm/s and 35 mm3/s, 3DJake's spec table says <=500 mm/s and 30 mm3/s. This is exactly the kind of sibling contamination the 3-series suffers (X-Max 3 is 600 mm/s / 35 mm3/s). Siblings: X-Max 3 (325x325x315, 900 W) and X-Smart 3 (175x180x170, no chamber heat, 300 °C)[1][2][5][3] | Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[3][1][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 280 x 280 x 270 mm advertised[1][2] | 175 x 180 x 170 mm advertised[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 511 x 527 x 529 mm[1] | 370 x 362 x 397 mm[3] |
| Net weight (kg) | 24.3 kg net[1] | 10.5 kg[3] |
| Frame construction & material | All-metal frame per QIDI's US page; no further breakdown published[2] | QIDI publishes no frame-material breakdown for this model[3] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a heated chamber[1][2] | No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 65 °C, independent chamber heating (manufacturer claim)[1][2] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[1] | CoreXY[3][4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Linear optical axis of high-strength steel[1] | Not documented |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Double Z axis[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Conflicting manufacturer claims: QIDI's US page says 600 mm/s, 3DJake's spec table says <=500 mm/s. The lower, more conservative figure is used as the sortable value[1][2] | <=500 mm/s (manufacturer claim)[3][4] |
| Max acceleration (claimed, mm/s²) | 20,000 mm/s2 (manufacturer claim)[2] | 20,000 mm/s2 (manufacturer claim)[4] |
| Max volumetric flow claimed (mm³/s) | Conflicting: 30 mm3/s (3DJake) vs 35 mm3/s (QIDI US page). Lower figure used[1][2] | 30 mm3/s extruder flow (manufacturer claim)[3][4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | High-flow direct-drive extruder, 1.75 mm filament[1][2] | Direct-drive extruder, single, 1.75 mm filament[3][4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Ceramic heating core. Copper-alloy nozzle head for normal materials, hardened-steel nozzle head for abrasives. 0.4 mm stock, 0.2/0.6/0.8 mm optional[1] | Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[3][4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | <=350 °C claimed[1][2] | <=300 °C claimed[3][4] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Brass[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | <=120 °C claimed[1][2] | <=120 °C claimed[3][4] |
| Bed surface (material, texture, coating), single/double-sided | Double-sided flexible magnetic RF plate[1] | Double-sided flexible magnetic RF plate[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic bed levelling; probe technology not named[2] | 16-point automatic bed levelling per QIDI's US page; probe technology not named[4] |
| Mesh grid size (probe point count — firmware evidence) | Not documented | 16 points (QIDI's US page). Not verified against firmware[4] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted; type and location not published[1] | Filament detection fitted; type and location not published[3] |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Cortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[1][2] | Cortex-A53 64-bit at 1.5 GHz, 1 GB DDR3, 8 GB eMMC[3] |
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 50/60 Hz[1] | 100-240 VAC, 50/60 Hz[3] |
| Total rated power draw | 800 W rated[1] | 350 W rated[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[2] | Klipper[4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch touchscreen, 800 x 480[1] | 4.3-inch touchscreen[4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi (150M 2.4G), Ethernet, USB flash drive[1] | Wi-Fi and USB. No Ethernet listed for this model[3][4] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 1-year coverage (QIDI standard store terms)[6] | 1-year coverage (QIDI standard store terms)[6] |
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.
