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 Plus4, sold as "Plus4 3D Printer". QIDI's own wiki files it under X-Plus4[4][5]
Release date (announcement and actual shipping)Not documentedAnnounced September 2024; QIDI ran launch promotional pricing in the week of 20-27 September 2024 (secondary reporting, not a QIDI press release)[6]
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]$649.00 on us.qidi3d.com for the Plus4 + 1 filament variant against a $799.00 compare-at price; $699.00 on qidi3d.com against $799.00. Checked Aug 2026[4][5]
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][7]Two purchasable variants: Plus4 + Filament x1 at $649 and Plus4 Combo + Filament x1 at $799 (Combo adds the QIDI Box multi-material unit). Distinct from the older X-Plus 3 (280x280x270, 350 °C) and from the newer Plus5 (320x320x300)[5][4]
Market position: superseded? successor announced?Not documentedSuperseded at the top of the large-format line by the Plus5, launched 5 August 2026 with 18% more build volume; Plus4 still listed and in stock Aug 2026[8][9]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable165 x 72 x 170 mm[1][3]305 x 305 x 280 mm advertised. No independently measured usable envelope found[4][6]
Machine footprint (mm) & clearance needed (cable/spool overhang)290 x 290 x 430 mm[1][3]505 x 487 x 550 mm[6]
Net weight (kg)10 kg[1][3]32 kg gross (3DJake). QIDI does not publish a net weight on the product page[6]
Frame construction & materialBlack textured housing with a neon-green plastic cover[1]Enclosed CoreXY chassis with double-layer chamber insulation; QIDI does not publish a frame material breakdown[4]
Enclosure: open / enclosed; panel material; door/lidOpen-frame MSLA with a UV-blocking plastic cover[1]Fully enclosed, double-layer insulated chamber with second-generation active heating to 65 °C[4][6]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented65 °C, actively heated by a 400 W heater which QIDI says reaches setpoint in about 8 minutes (manufacturer claim)[4][6]
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[6]
X-axis guide type (rods / linear rails / V-wheels; size)One linear rail; lead screw (not a ball screw)[1][3]Not documented
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedDual independent Z motors on 10 mm linear shafts and screws[4]
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented600 mm/s (manufacturer claim, tool-head maximum)[6]
Max acceleration (claimed, mm/s²)Not documented<=20,000 mm/s2 (manufacturer claim)[6]
Extruder
Type (direct drive / bowden) & design nameNot documentedDirect drive with hardened steel dual gears, 1.75 mm filament[4][6]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Not documentedSecond-generation 80 W bimetal hotend with a multi-metal composite hardened-tip nozzle; 0.4 mm standard, 0.2/0.5/0.8 mm optional[4][6]
Max nozzle temp claimed AND firmware max temp limit (both values)Not documented<=370 °C claimed. No firmware max_temp verified for this model[4][6]
Heater cartridge power (W)Not documented80 W hotend heater (manufacturer figure)[4]
Heated Bed & Surface
Max bed temp claimed AND firmware limitNot documentedConflicting manufacturer figures: QIDI's own Plus4 page states a 100 °C bed temperature, 3DJake's spec table states <=120 °C. Not resolved; the lower vendor-published figure is used as the sortable value[4][6]
Bed surface (material, texture, coating), single/double-sidedNot documented6 mm aluminium-substrate heated bed with a double-sided textured PEI plate[4][6]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)Not documentedFull-auto calibration; QIDI markets "hands-free automatic" levelling and does not name the probe technology on the product page[4][6]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament run-out sensor, plus a filament cutter and filament tangle detection (tangle mechanism not described)[6]
Multi-material/multi-color capability or official upgrade pathNot documentedQIDI Box multi-material unit supported; sold bundled as the Plus4 Combo[4][5]

Cloud service & phone app; LAN-only mode possible?Not documentedMobile and computer control, remote cloud or LAN-only operation[4]

Calibration Routines & QoL
Assembly level & time from unbox to first printNot documentedQIDI claims about 10 minutes from unbox to printing[4]

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][7]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.
