Pixel pitch describes the screen, not the tolerance of the part · review
Phrozen Sonic Mini 8K S, 22 µm XY review
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.
The bottom line The listing gives the resin figure that matters most for comparison — pixel pitch — along with the build volume and slicer support. It says nothing about the vat, the film or handling resin, and those have to come from the maker’s documentation.
The Sonic Mini 8K S listing, bullet by bullet
Five bullets: a beginner-friendly printer with an attractive price-to-performance ratio; an XY resolution of 22 micrometres from the 8K mono LCD; a build volume of 16.5 × 7.2 × 17 cm with a load capacity of up to 10 kg; support for open-source software and slicers such as Lychee, Chitubox and Tango; and precise Z-axis calibration.
A pitch, published
22 µm is the figure that lets this printer be compared. Resolution depends on screen size; pixel pitch does not. This listing publishes both, and the page reports the pitch as a specification of the screen, never as a tolerance on a part.
A tall, narrow volume
165 × 72 × 170 mm suits standing miniatures and small parts printed at an angle. The 72 mm dimension is the limit to check before planning a wider piece.
What the page does not cover
Light source, vat, release film and kit contents are all absent, and there is no word on resin handling or ventilation. The resin maker’s safety data sheet applies to every bottle used in it.

Questions makers ask before buying
Is 22 µm the accuracy of a print?
No. It is the XY resolution the maker publishes, which is the size of the smallest step the screen can project. How closely a part matches its model also depends on the resin, exposure, supports and calibration.
Which slicers does it support?
The fourth bullet names Lychee, Chitubox and Tango, and describes support for open-source software.
