Photon Mono 4 Ultra

Overview

The Photon Mono 4 Ultra upgrades Anycubic's entry 10K printer with a COB (chip-on-board) light source behind a Fresnel lens, rated at >=3500 µW/cm² and over 90% uniformity, replacing the base Mono 4's parallel light matrix. It keeps the same 7-inch, 10K monochrome LCD (9024 x 5120 pixels, 17 x 17 µm XY resolution) and the same 153.4 x 87 x 165 mm (2.2L) build volume, so detail and print size stay the same, with the gains coming in speed, light quality, and monitoring instead. Standard resin prints at up to 80 mm/h, and Anycubic's High-Speed Resin 2.0 pushes that to 120 mm/h, both at 0.1mm layers; layer height ranges from 0.02 to 0.15 mm. The vat uses ACF release film rather than FEP, which Anycubic says improves light transmission and lowers peel force. Automated monitoring adds failed-print detection, a pre-print resin-level check, resin residue detection, release-film usage tracking, and power-loss print resume. Unlike the base Mono 4, the Ultra connects over USB, Wi-Fi, and LAN. It does not have a built-in camera, so monitoring relies on internal sensors rather than visual feedback. It's a good fit for hobbyists who've outgrown the base Mono 4's manual workflow but don't need the M7 series' larger screens.
