Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Phrozen Sonic Mini 8K S 7.1" LCD 3D Printer. Manufacturer number 51010040501102[1][2][3]LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[4]
Street price (USD; dated snapshot per entry)$270.00 on us.phrozen3d.com, backordered with an end-of-September ETA, checked Aug 2026. The collection page rendered it as unavailable on the same day[3][2]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)Phrozen's 7.1-inch line is easy to confuse: the Sonic Mini 8K S ($270) sits beside the older Sonic Mini 8K ($340, sold out) and the 5.5-inch Sonic Mini ($129.99). The 10.1-inch Sonic Mighty family is a different size class entirely. The 8K S is the only one of the group with a single linear rail and a lead screw rather than a ball screw[2][1][3][5]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[4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable165 x 72 x 170 mm[1][3]180 x 180 x 165 mm[4]
Machine footprint (mm) & clearance needed (cable/spool overhang)290 x 290 x 430 mm[1][3]200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[4]
Net weight (kg)10 kg[1][3]3 kg net; 5.5 kg with the hard case[4]
Frame construction & materialBlack textured housing with a neon-green plastic cover[1]Folding frame designed to fit in a filament box; supplied with a black hard case[4]
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a UV-blocking plastic cover[1]Open frame[4]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)MSLA, single Z axis on one linear rail with a lead screw, straight-lift peel[1][3]CoreXY, inverted — the machine prints upside down[4]
X-axis guide type (rods / linear rails / V-wheels; size)One linear rail; lead screw (not a ball screw)[1][3]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented250 mm/s maximum print speed (manufacturer claim)[4]
Max acceleration (claimed, mm/s²)Not documented8,000 mm/s2 (manufacturer claim)[4]
Extruder
Type (direct drive / bowden) & design nameNot documentedBowden-style, single extrusion[4]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedPS plated-copper nozzle, 0.4 mm[4]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented260 °C maximum (manufacturer claim)[4]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedPlated copper[4]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documented85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[4]
Bed surface (material, texture, coating), single/double-sidedNot documentedHeated removable ITO glass bed[4]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedLDO Positron mainboard[4]
PSU (brand, wattage, rail voltage)Not documentedDC 24 V, 200 W[4]
Input voltage (110/220 V, switch or auto)24 V DC, 2 A[3]Not documented
Total rated power draw48 W maximum system power[3]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not named by Phrozen. Native file format .PRZ; compatible slicers CHITUBOX, Lychee and VoxelDance Tango[1][3]Klipper[4]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch touch panel (control panel — not the masking LCD, see W1)[3]3.5-inch LCD touchscreen[4]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB only[1][3]Wi-Fi, USB, Ethernet[4]
Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedSelf-assembly kit, manufactured in China[4]
Materials Support
Officially supported filament list405 nm photopolymer resin; no closed compatibility list published[1]PLA and PETG only, per the manufacturer[4]
Resin & MSLA
Masking LCD7.1-inch 8K monochrome masking LCD, XY pixel pitch 22 um. Phrozen does not publish the pixel count for this model[1][3]Not documented
Light sourceLinear projection LED module. Wavelength not published for this model[1][3]Not documented
Vertical print speedmm/hMax 80 mm/h (manufacturer claim). Phrozen does not state the layer height or resin type the figure assumes[3]Not documented
Layer height range0.01-0.30 mm[3]Not documented
Release filmFEP film — note this is plain FEP, whereas the Sonic Mighty Revo 14K ships nFEP. No rated life published[3][5]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.
