Anycubic Photon Mono SQ

The Anycubic Photon Mono SQ is an LCD (MSLA) resin printer that stands out with its near-square 128×120×200 mm build area. It suits hobbyists printing miniatures, wargaming figures and models who want more print area without jumping to a pricier machine.

At its core is a 6.9" monochrome LCD with 3K resolution (2560×2400) and a 50 µm pixel size. The mono panel shortens layer exposure, so print speed reaches 60 mm/h — about three times faster than the original Photon. The 405 nm UV light source is a matrix array with power adjustable from 30% to 100%, letting you dial exposure in for different resins. Control is via a 3.5" resistive touchscreen, and files load from a USB drive.

Pros

• Large, near-square 128×120×200 mm build area — 1.7× bigger than the Photon Mono and Mono SE
• Mono LCD speeds up curing: up to 60 mm/h and roughly 2,000 hours of screen life
• Adjustable 30–100% UV power — flexible exposure tuning across different resins
• Stable Z axis on a rail with a lead screw and clearance nut — clean layers without banding
• Anti-scratch FEP film protects the LCD from resin leaks and extends its lifespan

Cons

• 3K resolution (50 µm) no longer matches modern 4K/8K printers — voxels are more visible on smooth surfaces
• Manual paper-based platform leveling instead of automatic leveling
• USB-drive transfer only: no Wi-Fi or network printing
• Discontinued — Anycubic now points to the Photon Mono 2; mostly available secondhand

The Photon Mono SQ fits anyone who values print area: several miniatures in a single run, larger busts, figures and detailed models. It's a pick for home hobby use and small workshops ready to handle resin and post-processing (washing and UV curing).

Bottom line: a solid resin printer for its era with an unusually large square build area; it trails newer 4K/8K models on detail, but remains a capable budget workhorse.
