| Class | BEDSLINGER | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | ELEGOO Neptune 4 Max[1] | Phrozen Sonic Mini 8K S 7.1" LCD 3D Printer. Manufacturer number 51010040501102[2][3][4] |
| Release date (announcement and actual shipping) | Listed on the ELEGOO US store from 20 September 2023 (Shopify publish date)[5] | Not documented |
| Street price (USD; dated snapshot per entry) | $389.00 on us.elegoo.com, Aug 2026, against a compare-at price of $559.99; Ribbon-Cable and Type-C printhead variants are the same price[5] | $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[4][3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Largest Neptune 4. The trade-off against the smaller models is easy to miss: the bed only reaches 85 C (against 100 C on the Plus and 110 C on the base Neptune 4) and acceleration is capped at 8000 mm/s2 (against 12000 and 20000), because of the mass of a 430 x 430 mm moving bed. Two printhead variants, Ribbon-Cable and Type-C, are sold under one SKU[1][6][7][5] | 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[3][2][4][8] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 420 x 420 x 480 mm; printing platform 430 x 430 mm[1] | 165 x 72 x 170 mm[2][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 658 x 632 x 740 mm; ELEGOO's maximum size for machine activity is 658 x 950 x 960 mm including rack and tray - allow nearly a metre of depth and height[1] | 290 x 290 x 430 mm[2][4] |
| Net weight (kg) | 18.1 kg net, 21.8 kg gross[1] | 10 kg[2][4] |
| Frame construction & material | CNC-machined aluminium extrusion frame[1] | Black textured housing with a neon-green plastic cover[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Open-frame MSLA with a UV-blocking plastic cover[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian i3 bed-slinger[1] | MSLA, single Z axis on one linear rail with a lead screw, straight-lift peel[2][4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Not documented | One linear rail; lead screw (not a ball screw)[2][4] |
| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Two lead screws with two tie rods[9] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | "Silent Drive (All Axes)"; no driver part number published[9] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 500 mm/s max toolhead speed (manufacturer claim)[1] | Not documented |
| Recommended/typical print speed | 250 mm/s recommended printing speed against the 500 mm/s ceiling (ELEGOO's own figure); default acceleration is 4000 mm/s2[9] | Not documented |
| Max acceleration (claimed, mm/s²) | 8000 mm/s2 max toolhead acceleration (manufacturer claim) - the lowest in the Neptune 4 family[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Dual-gear direct extruder with 2 fans[9] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Brass nozzle, 0.4 mm, with a titanium-alloy heat break[9] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C claimed max nozzle temperature[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 85 C max heated bed temperature at 25 C ambient - well below the 100-110 C of the smaller Neptunes, which limits ABS/ASA work despite them being on the compatibility list[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | PEI spring steel sheet, now upgraded to a dual-sided textured PEI + PLA-specific surface; platform 430 x 430 mm[9] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Manual levelling combined with 121-point auto-levelling[9] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection and power-loss resume printing[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | "Klipper High-Speed Quiet Motherboard" is all ELEGOO publishes[9] | Not documented |
| Input voltage (110/220 V, switch or auto) | 100-120 V / 220-240 V, 50/60 Hz[1][9] | 24 V DC, 2 A[4] |
| Total rated power draw | 320 W rated power, 24 V output[9] | 48 W maximum system power[4] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[9] | Not named by Phrozen. Native file format .PRZ; compatible slicers CHITUBOX, Lychee and VoxelDance Tango[2][4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch colour capacitive touch screen[9] | 3.5-inch touch panel (control panel — not the masking LCD, see W1)[4] |
| On-device UI capabilities (model preview, per-object controls, etc.) | Colour capacitive touch UI; ElegooSlicer recommended, Orca and Cura supported[9] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB and WLAN file transfer[1] | USB only[2][4] |
| Materials Support | ||
| Officially supported filament list | PLA, TPU, PETG, ABS, ASA, Nylon - but note the 85 C bed ceiling against ABS and ASA[1] | 405 nm photopolymer resin; no closed compatibility list published[2] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Operating sound published as 65 dB or less - a manufacturer figure with no distance or method stated[9] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 12 months on brand-new machines and parts, but ELEGOO's own table excludes a long list of parts from that: PEI plate / build plate / nozzle kit / PTFE tube / heater / thermistor / hot end / packaging / manual / tools carry no warranty at all, and the extruder, extruder kit and printhead kit get 6 months. Certified pre-owned machines carry no warranty[10] | Not documented |
| Resin & MSLA | ||
| Masking LCD | Not documented | 7.1-inch 8K monochrome masking LCD, XY pixel pitch 22 um. Phrozen does not publish the pixel count for this model[2][4] |
| Light source | Not documented | Linear projection LED module. Wavelength not published for this model[2][4] |
| Vertical print speedmm/h | Not documented | Max 80 mm/h (manufacturer claim). Phrozen does not state the layer height or resin type the figure assumes[4] |
| Layer height range | Not documented | 0.01-0.30 mm[4] |
| Release film | Not documented | FEP film — note this is plain FEP, whereas the Sonic Mighty Revo 14K ships nFEP. No rated life published[4][8] |
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.
