| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[1] | QIDI Q1 Pro, listed by QIDI as "Q1 Pro 3D Printer". QIDI traded as Qidi Tech until end-2024[2] |
| Release date (announcement and actual shipping) | Not documented | Not stated on QIDI's own product page; the page now carries a discontinuation notice instead of a launch date (checked Aug 2026)[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $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[2][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The defining trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[1] | 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[2][3] |
| Market position: superseded? successor announced? | Not documented | Discontinued and out of production; QIDI states spare parts and support for existing owners remain available. Replaced by the Q2[2][3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 165 mm[1] | 245 x 245 x 240 mm advertised (QIDI). No independently measured usable envelope found[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[1] | 477 x 467 x 489 mm machine dimensions (QIDI)[2][4] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | 17 kg net, 20.3 kg gross (QIDI). 3DJake lists the 20.3 kg figure as gross weight[2][4] |
| Frame construction & material | Folding frame designed to fit in a filament box; supplied with a black hard case[1] | Metal CoreXY motion frame with panelled enclosure; QIDI publishes no frame-material breakdown for this model[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame[1] | Fully enclosed with independent chamber heating to 60 °C; QIDI does not publish the panel materials for this model[2][4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 60 °C, actively heated (manufacturer claim — this is a heater setpoint, not a measured passive figure)[2][4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, inverted — the machine prints upside down[1] | CoreXY[4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | 10 mm linear steel rods with automatically tensioned belt (manufacturer description)[4] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Not documented | Independent dual Z lead-screw motors[4] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 250 mm/s maximum print speed (manufacturer claim)[1] | 600 mm/s, worded by QIDI as maximum tool-head speed (manufacturer claim, not a sustained printing speed)[2][4] |
| Max acceleration (claimed, mm/s²) | 8,000 mm/s2 (manufacturer claim)[1] | <=20,000 mm/s2 (manufacturer claim)[2][4] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden-style, single extrusion[1] | Direct-drive extruder with hardened steel gears[2][4] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | PS plated-copper nozzle, 0.4 mm[1] | Tri-metal hotend with a ceramic heater plate and a bimetal nozzle, 0.4 mm standard[2][4] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 260 °C maximum (manufacturer claim)[1] | <=350 °C claimed. No firmware max_temp verified for this model[2][4] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Plated copper[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[1] | <=120 °C claimed. No firmware limit verified for this model[2][4] |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | Double-sided textured PEI plate on an aluminium substrate bed[2][4] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic levelling; QIDI markets it as "hands-free automatic levelling" with dual sensors, without naming the probe technology[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out sensor fitted; QIDI also lists filament tangle detection without describing the mechanism[4] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Auxiliary part-cooling fan plus a chamber circulation fan (fan count and duct design not published)[4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | LDO Positron mainboard[1] | Not documented |
| PSU (brand, wattage, rail voltage) | DC 24 V, 200 W[1] | Not documented |
| Input voltage (110/220 V, switch or auto) | Not documented | 100-240 VAC, 50/60 Hz[4] |
| Total rated power draw | Not documented | 350 W plus 300 W for chamber heating (rated)[2][4] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[1] | Klipper, running on a 64-bit processor per QIDI. Exact fork and version not published on the product page[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch LCD touchscreen[1] | 4.3-inch touchscreen, 272 x 480[2][4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB, Ethernet[1] | Wi-Fi 6 (QIDI states "150M 2.4G") and USB 2.0. No Ethernet listed for this model[2][4] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Built-in camera, up to 1080p, timelapse supported. Framerate not published[2][4] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit, manufactured in China[1] | Ships fully assembled[2] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery listed as a feature; mechanism not published[4] |
| Materials Support | ||
| Officially supported filament list | PLA and PETG only, per the manufacturer[1] | QIDI lists compatibility with common filaments; storage 32 GB eMMC. No per-material list published on the current page beyond the general claim[2] |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | Not documented | 1-year coverage, 14-day no-reason return, lifetime tech guidance (QIDI's standard terms as shown on its store)[5] |
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.
