ClassCOREXYIDEX
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]Snapmaker J1S High Speed IDEX 3D Printer[2][3]
Street price (USD; dated snapshot per entry)Not documented$1,399.00 at MatterHackers, listed as currently unavailable with a pre-order option quoting roughly 5 weeks, checked Aug 2026[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]The J1s differs from the original J1 by an additional part-cooling fan. Usable volume depends on the print mode: 300 x 200 x 200 mm in default and backup modes, 160 x 200 x 200 in copy mode, 150 x 200 x 200 in mirror mode[2][3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable180 x 180 x 165 mm[1]300 x 200 x 200 mm in default and backup modes[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[1]539 x 401 x 464 mm[2]
Net weight (kg)3 kg net; 5.5 kg with the hard case[1]25 kg net[2]
Frame construction & materialFolding frame designed to fit in a filament box; supplied with a black hard case[1]Aluminium-alloy frame with one-piece die casting and linear rails; Snapmaker quotes rail repeatability of +/-0.03 mm in X/Y and +/-0.02 mm in Z[3]
Enclosure: open / enclosed; panel material; door/lidOpen frame[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY, inverted — the machine prints upside down[1]IDEX — two independently driven extruders[2][3]
X-axis guide type (rods / linear rails / V-wheels; size)Not documentedLinear rails[3]
Speed & Acceleration
Max print speed (claimed, mm/s)250 mm/s maximum print speed (manufacturer claim)[1]350 mm/s maximum (manufacturer claim)[3]
Max acceleration (claimed, mm/s²)8,000 mm/s2 (manufacturer claim)[1]10,000 mm/s2 maximum (manufacturer claim)[3]
Extruder
Type (direct drive / bowden) & design nameBowden-style, single extrusion[1]Not documented
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 (manufacturer claim)[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 limit85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[1]100 °C maximum (manufacturer claim)[2]
Bed surface (material, texture, coating), single/double-sidedHeated removable ITO glass bed[1]Custom dual-sided PEI glass plate: glossy glass on one face, PEI coating on the other[2][3]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documented3-point bed levelling, which Snapmaker contrasts with 9-16 point systems; assisted calibration quoted at about 10 minutes[3]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)LDO Positron mainboard[1]Not documented
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documented1 GB RAM, 8 GB eMMC; the 5-inch display runs Android[2]
PSU (brand, wattage, rail voltage)DC 24 V, 200 W[1]Not documented
Input voltage (110/220 V, switch or auto)Not documentedAC 100-240 V, 50/60 Hz, 4.4 A max input; DC 24 V, 400 W max output[2]
Total rated power drawNot documented400 W maximum output[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Klipper[1]Not named by Snapmaker; the supplied slicer is Luban, with third-party software supported[2]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch LCD touchscreen[1]5-inch Android display, 1280 x 720[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveWi-Fi, USB, Ethernet[1]Wi-Fi, USB cable, USB flash drive[2]
Calibration Routines & QoL
Assembly level & time from unbox to first printSelf-assembly kit, manufactured in China[1]Not documented
Materials Support
Officially supported filament listPLA and PETG only, per the manufacturer[1]PLA, ABS, HIPS, PC, TPU, TPE, PETG, ASA, PP, PVA, PA, PA-GF, PA-CF[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedLess than 50 dBA claimed by the manufacturer. No independent measurement; distance and method not stated[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.
