| Property | Positron V3.2COREXY | QIDI Plus5COREXY |
|---|---|---|
| Identity | ||
| Brand | Positron3D | QIDI |
| 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 Plus5, sold as "QIDI Plus5 3D Printer"[2][3] |
| Release date (announcement and actual shipping) | Not documented | Launched 5 August 2026, 09:00 EDT / 15:00 CEST[4] |
| Launch MSRP (USD) | Not documented | $749 regular launch price; a launch-window member discount put it under $700[4] |
| Street price (USD; dated snapshot per entry) | Not documented | $749.00 for the standard model on us.qidi3d.com, checked Aug 2026. Other variants: Polar Cooler bundle $899.00, Plus5 Combo $899.00, Combo + Polar Cooler $1,049.00. No compare-at price listed[2] |
| 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] | Four purchase variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), and Combo + Polar Cooler. The Polar Cooler is a pre-sale add-on shipping separately, so its specs are not Plus5 specs. Replaces the Plus4 (305x305x280, 450 W + 400 W chamber)[2][4] |
| Market position: superseded? successor announced? | Not documented | Current flagship of QIDI's large-format line as of Aug 2026; sits below the Max4 (390x390x340)[2][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 165 mm[1] | 320 x 320 x 300 mm advertised — QIDI states this is about 18% more volume than the Plus4[2][3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[1] | 500 x 488 x 558 mm[3] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | 29.0 kg net[3] |
| Frame construction & material | Folding frame designed to fit in a filament box; supplied with a black hard case[1] | Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame[1] | Fully enclosed, with a 3-stage air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[2][3] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 65 °C, actively heated, 550 W chamber heater — reported as a 37.5% increase in heater power over the Plus4 (manufacturer claim)[3][4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, inverted — the machine prints upside down[1] | CoreXY[3] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | High-precision linear rails on X[2][4] |
| Belts (type, width, e.g. Gates?) | Not documented | 1.5GT belts, 9 mm wide — wider than the 2GT 6 mm belts common in this class[2][4] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 250 mm/s maximum print speed (manufacturer claim)[1] | 600 mm/s (manufacturer claim)[3] |
| Max acceleration (claimed, mm/s²) | 8,000 mm/s2 (manufacturer claim)[1] | <=20,000 mm/s2 (manufacturer claim)[3] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Resonance compensation listed as a feature; implementation not named on the product page[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden-style, single extrusion[1] | Direct drive with hardened dual gears[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | PS plated-copper nozzle, 0.4 mm[1] | Ceramic heating-plate hotend with a bimetal nozzle; 0.4 mm standard, 0.2/0.6/0.8 mm optional[3] |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 260 °C maximum (manufacturer claim)[1] | <=370 °C claimed[2][3] |
| 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, described by QIDI as an even-heating bed[2][3] |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | Aluminium silicone heated bed with a dual-sided textured PEI plate[3] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic levelling using an integrated load cell; QIDI describes it as direct nozzle-contact detection[3][4] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out sensor, plus a filament cutter[3] |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | 3-in-1 filtration: G3 pre-filter, H12 HEPA, coconut-shell activated carbon; QIDI claims 99.5% capture of airborne particles and dust[2][3][4] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | LDO Positron mainboard[1] | Not documented |

| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[1] | Not stated on the product page. QIDI's slicer ecosystem is QIDI Studio, and Orca/PrusaSlicer are listed as supported[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch LCD touchscreen[1] | 4-inch touchscreen, 480 x 320[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB, Ethernet[1] | Wi-Fi 2.4 GHz / 5 GHz, Ethernet, USB; 32 GB eMMC storage plus USB 2.0 flash drive[3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | AI camera with failure detection, up to 1080p, timelapse supported (low frame rate)[2][3][4] |
| LED chamber/toolhead lighting | Not documented | RGB status light[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit, manufactured in China[1] | 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.
