| Property | QIDI X-Smart 3COREXY | Snapmaker U1TOOLCHANGER |
|---|---|---|
| Identity | ||
| Brand | QIDI | Snapmaker |
| Class | COREXY | TOOLCHANGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[1][2] | Snapmaker U1 3D Printer[3] |
| Release date (announcement and actual shipping) | Not published by QIDI on the pages checked (Aug 2026)[1][2] | Not documented |
| Street price (USD; dated snapshot per entry) | $399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[2] | $849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[1][4][5] | An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 175 x 180 x 170 mm advertised[1][2] | 270 x 270 x 270 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 370 x 362 x 397 mm[1] | 584 x 499 x 730 mm[3] |
| Net weight (kg) | 10.5 kg[1] | 18.2 kg[3] |
| Frame construction & material | QIDI publishes no frame-material breakdown for this model[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | No heated chamber. 3DJake's table records "Heated chamber: No"; QIDI does not describe an enclosure for this model[1] | Open as sold; a top cover is an optional accessory that raises the supported material range[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY[1][2] | Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[3] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | <=500 mm/s (manufacturer claim)[1][2] | 500 mm/s maximum toolhead speed (manufacturer claim)[3] |
| Max acceleration (claimed, mm/s²) | 20,000 mm/s2 (manufacturer claim)[2] | 20,000 mm/s2 maximum (manufacturer claim)[3] |
| Max volumetric flow claimed (mm³/s) | 30 mm3/s extruder flow (manufacturer claim)[1][2] | 32 mm3/s maximum hotend flow (manufacturer claim)[3] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input shaping with an accelerometer, run as a calibration routine[3] |
| Extrusion Pressure Control | ||
| Pressure advance (Klipper) / linear advance (Marlin) supported? | Not documented | Pressure advance, with automatic flow compensation calibration[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct-drive extruder, single, 1.75 mm filament[1][2] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass nozzle head. 0.4 mm stock, 0.2/0.6/0.8 mm optional[1][2] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | <=300 °C claimed[1][2] | 300 °C maximum (manufacturer claim)[3] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Brass[1] | Stainless steel as standard; hardened steel needed for fibre-filled grades[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | <=120 °C claimed[1][2] | 100 °C maximum (manufacturer claim)[3] |
| Bed surface (material, texture, coating), single/double-sided | Double-sided flexible magnetic RF plate[1] | Flexible steel sheet with a PEI surface[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 16-point automatic bed levelling per QIDI's US page; probe technology not named[2] | Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[3] |
| Mesh grid size (probe point count — firmware evidence) | 16 points (QIDI's US page). Not verified against firmware[2] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection fitted; type and location not published[1] | Filament run-out detection, plus air-printing detection and RFID filament recognition[3] |
| Multi-material/multi-color capability or official upgrade path | Not documented | Four toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Main plus auxiliary part-cooling fans[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] | Not documented |
| Input voltage (110/220 V, switch or auto) | 100-240 VAC, 50/60 Hz[1] | Not documented |
| Total rated power draw | 350 W rated[1] | Maximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[3] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[2] | Klipper[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch touchscreen[2] | 3.5-inch, 320 x 480 touchscreen[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi and USB. No Ethernet listed for this model[1][2] | Wi-Fi 2.4 GHz (802.11b/g/n) and USB flash drive. No Ethernet listed[3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | 2 MP built-in chamber camera for live view[3] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery supported; mechanism not published[3] |
| Materials Support | ||
| Officially supported filament list | Not documented | Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[3] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 1-year coverage (QIDI standard store terms)[6] | 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.
