A published pixel against a guarded screen
Which resin 3D printer: the Phrozen Sonic Mini 8K S or the ELEGOO Mars 5?
Both are compact mono-LCD resin 3D printers, and neither listing says anything about the vat, the film, the kit contents or ventilation for resin fumes. The Phrozen publishes the finer screen, 8K on 7.1 inches with a 22 µm pixel, and a 165 × 72 × 170 mm build volume. The ELEGOO publishes a 4K screen without a pixel pitch, a 143.43 × 89.6 × 150 mm build volume, a COB light source and protections for the screen and the light.

|---|---|---|
| Screen resolution | 8K mono LCD, 7.1 inch, title and second bullet | 4K mono LCD, title and fourth bullet; no pixel count across and down is given |
| Pixel pitch | 22 µm, given as an XY resolution of 22 micrometres | Not published |
| Build volume | 165 × 72 × 170 mm, title; 16.5 × 7.2 × 17 cm in the third bullet | 143.43 × 89.6 × 150 mm, written in the title as mm³ |
| Light source | Not published | COB light source, fourth bullet |

A tick means one listing published something the other did not, or published a better figure. It does not mean the product is better, and the column is not a score out of anything: a maker who says less loses lines here without losing a comparison. The two verdicts below are where the page is settled.
The Phrozen Sonic Mini 8K S suits miniatures and small detailed parts, where a published 22 µm pixel lets the screen be compared, and a taller, narrower build area fits upright models. The pixel is not the tolerance of the finished part.
The ELEGOO Mars 5 suits a first resin setup where one-click levelling, residue detection before the screen is damaged and an overheat stop matter more than a pixel figure. Its build area is shorter and wider than the Phrozen’s.
It makes the projected pixel finer: the Phrozen publishes 22 µm, the ELEGOO publishes no pitch. How closely a finished part matches its file also depends on exposure, resin shrinkage, washing and curing, so the screen figure is not a tolerance.
Neither clearly. The Phrozen declares 165 × 72 × 170 mm and the ELEGOO 143.43 × 89.6 × 150 mm: the first is taller and longer, the second wider. The shape of the parts decides which suits.
No. Neither publishes a ventilation provision; the ELEGOO cooling system is for the machine. Handling and ventilation for resin come from the resin maker’s safety data sheet.
8K mono LCD, 7.1 inch · 22 µm XY resolution · 165 × 72 × 170 mm build volume · load up to 10 kg · Lychee, Chitubox and Tango supported
A 7.1 inch 8K mono-LCD resin printer that publishes a 22 µm XY resolution and a 165 × 72 × 170 mm build volume, and supports several third-party slicers.
Best for: A miniature printer where a published 22 µm pitch and a choice of slicer matter more than build area.
≈ 361 €
4K mono LCD · COB light source · 143.43 × 89.6 × 150 mm build volume · one-click auto-levelling · residue detection · overheat stop above 80 °C LED temperature
A 4K mono-LCD resin printer with one-click auto-levelling, a sensor that detects residue before it damages the screen, and an overheat cut-out, whose listing does not publish the pixel pitch.
Best for: A first resin printer for miniatures, where protection against a damaged screen and a self-check matter more than size.
