| 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] | UltiMaker Factor 4[4] |
| Release date (announcement and actual shipping) | Not documented | Announced 22 April 2024, shown at HANNOVER MESSE 2024 (22-26 April) and TCT Asia (7-9 May 2024)[4] |
| Launch MSRP (USD) | Not documented | Starting at approximately $20,000[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] | Shares the 330 x 240 x 300 mm envelope with the UltiMaker S5, S7 and S8, which is the single most contaminated figure in UltiMaker's range. What separates the Factor 4 is the actively controlled 70 °C build volume, the climate-controlled 6-spool material station holding humidity below 15%, and HEPA filtration. UltiMaker also sells a Factor 4 Plus[4] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 165 x 72 x 170 mm[1][3] | 330 x 240 x 300 mm[4] |

| Net weight (kg) | 10 kg[1][3] | Not documented |
| Frame construction & material | Black textured housing with a neon-green plastic cover[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Open-frame MSLA with a UV-blocking plastic cover[1] | Enclosed with actively controlled chamber airflow and a HEPA filter[4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | Build volume temperature controlled up to 70 °C with actively controlled chamber airflow (manufacturer specification)[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] | Direct-drive dual extrusion; kinematic layout not stated in the source checked[4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | One linear rail; lead screw (not a ball screw)[1][3] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Not documented | Direct-drive dual extrusion[4] |
| Filament diameter | Not documented | 2.85 mm[4] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | Not documented | 340 °C maximum with the high-temperature print core (manufacturer claim)[4] |
| Filament Handling & Detection | ||
| Spool holder location & max spool size; drybox compatibility | Not documented | Automatic climate-controlled material handling and storage station holding humidity below 15%, storing up to six spools[4] |
| Cooling & Air Handling | ||
| Chamber/exhaust fan & filtration (activated carbon / HEPA) | Not documented | HEPA filter[4] |
| Electronics & Power | ||
| Input voltage (110/220 V, switch or auto) | 24 V DC, 2 A[3] | Not documented |
| Total rated power draw | 48 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] | 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] | Not documented |
| Materials Support | ||
| Officially supported filament list | 405 nm photopolymer resin; no closed compatibility list published[1] | UltiMaker-branded PPS CF, PLA, Tough PLA, Nylon, PETG, PET CF and PVA, plus validated third-party materials from BASF Forward AM, Kimya, Polymaker, LEHVOSS and Jabil[4] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Dimensional accuracy within +/-0.2 mm or +/-0.2% of feature nominal length; UltiMaker states it tested over 95% print-completion success. Manufacturer figures, not independent measurements[4] |
| 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][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.
