| Property | Positron V3.2COREXY | Raise3D Pro3IDEX |
|---|---|---|
| Identity | ||
| Brand | Positron3D | Raise3D |
| Class | COREXY | IDEX |
| 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] | Raise3D Pro3 3D Printer[2][3] |
| Street price (USD; dated snapshot per entry) | Not documented | $2,999.00 on Raise3D's own store, available, checked Aug 2026[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] | A crowded family with materially different prices: Pro3 $2,999, Pro3 Hyper Speed Package $4,999, Pro3 HS $4,599, Pro3 Plus HS $6,099. Build volume also changes with head count: 300 x 300 x 300 mm single-head, 255 x 300 x 300 mm dual-head. Raise3D's smaller E-series (E2 $1,999, E2CF $2,499, E3 $2,499) and the resin DF2 line are separate machines entirely[3][4][2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 165 mm[1] | 300 x 300 x 300 mm with one extruder; 255 x 300 x 300 mm with both[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[1] | 620 x 626 x 760 mm[2] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | 52.5 kg net[2] |
| Frame construction & material | Folding frame designed to fit in a filament box; supplied with a black hard case[1] | Fully assembled enclosed professional chassis[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame[1] | Enclosed with a HEPA and activated-charcoal filter[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, inverted — the machine prints upside down[1] | Dual-head with an electronic lifting system[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 250 mm/s maximum print speed (manufacturer claim)[1] | Not documented |
| Max travel speed | Not documented | Print-head travel speed 30-150 mm/s (manufacturer figure)[2] |
| Max acceleration (claimed, mm/s²) | 8,000 mm/s2 (manufacturer claim)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden-style, single extrusion[1] | Dual print heads, 1.75 mm filament[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | PS plated-copper nozzle, 0.4 mm[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 260 °C maximum (manufacturer claim)[1] | 300 °C maximum nozzle temperature[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm default; 0.2, 0.6, 0.8 and 1.0 mm available[2] |
| 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 maximum build-plate temperature, silicone heater[2] |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | Flexible steel plate with BuildTak[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Mesh levelling with flatness detection[2] |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | HEPA filter with activated charcoal[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | LDO Positron mainboard[1] | Motion controller Atmel ARM Cortex-M4 at 120 MHz with FPU; logic controller NXP ARM Cortex-A9 quad-core at 1 GHz[2] |
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | Not documented | 1 GB RAM, 8 GB onboard flash, embedded Linux[2] |
| 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 V AC, 50/60 Hz input; 24 V DC, 600 W output[2] |
| Total rated power draw | Not documented | 600 W output[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[1] | Embedded Linux on the logic controller; slicing is ideaMaker. Firmware base not published[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch LCD touchscreen[1] | 7-inch touchscreen, 1024 x 600[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB, Ethernet[1] | Wi-Fi, Ethernet, USB 2.0 x2; live camera[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | Live camera fitted; resolution not published[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit, manufactured in China[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA and PETG only, per the manufacturer[1] | PLA, ABS, HIPS, PC, TPU, TPE, PETG, ASA, PP, PVA, nylon, composites and metal/wood-filled grades[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Under 55 dB(A) while printing, manufacturer figure. No independent measurement; distance and method not stated[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XYZ step size 0.78125 / 0.78125 / 0.078125 micron (manufacturer specification, not an accuracy measurement)[2] |
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.
