| 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] | QIDI Tech i-Fast, also written iFast and "I-Fast"[4][5] |
| Release date (announcement and actual shipping) | Not documented | Not published on the listings checked (Aug 2026)[4][5] |
| 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] | $1,899.00 at Top 3D Shop, listed as discontinued with a 5-10 business-day lead time, checked Aug 2026. 3DJake no longer sells it[5][4] |
| 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][6] | Ships with two interchangeable dual-extruder assemblies — a standard dual head and a high-temperature dual head rated to 350 °C. Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[5][4] |
| Market position: superseded? successor announced? | Not documented | Discontinued; QIDI's current line is the Q, Plus and Max series[5][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 165 x 72 x 170 mm[1][3] | 330 x 250 x 320 mm advertised[4][5] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 290 x 290 x 430 mm[1][3] | 710 x 510 x 670 mm[5] |
| Net weight (kg) | 10 kg[1][3] | 33 kg net[5] |
| Frame construction & material | Black textured housing with a neon-green plastic cover[1] | Fully assembled enclosed metal-frame machine[4] |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a UV-blocking plastic cover[1] | Fully enclosed with a heated chamber[4][5] |
| 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] | Dual independent extruders in an enclosed Cartesian gantry[4][5] |
| 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 documented | 30-150 mm/s print speed range (manufacturer figure — a working range, not a peak marketing number)[5] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Direct-drive, two extruders. MK10-style nozzle[4][5] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 350 °C on the high-temperature extruder assembly[4][5] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm nozzle diameter[5] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 24 V DC, 2 A[3] | 110-220 V[5] |
| Total rated power draw | 48 W maximum system power[3] | 700 W rated[5] |
| 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] | Not documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch touch panel (control panel — not the masking LCD, see W1)[3] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | USB only[1][3] | Wi-Fi, LAN, USB flash drive[4][5] |
| Materials Support | ||
| Officially supported filament list | 405 nm photopolymer resin; no closed compatibility list published[1] | Carbon fibre, nylon, PETG, TPU, PC, ABS, PLA[5] |
| Resin & MSLA | ||
| Masking LCD | 7.1-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 source | Linear projection LED module. Wavelength not published for this model[1][3] | Not documented |
| Vertical print speedmm/h | Max 80 mm/h (manufacturer claim). Phrozen does not state the layer height or resin type the figure assumes[3] | Not documented |
| Layer height range | 0.01-0.30 mm[3] | Not documented |
| Release film | FEP film — note this is plain FEP, whereas the Sonic Mighty Revo 14K ships nFEP. No rated life published[3][6] | 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.
