The Anycubic Photon Mono 4 Ultra is a compact resin 3D printer designed for detailed small-format prints, particularly gaming accessories. Reviewers noted its mono light engine delivers better resolution and light energy than standard RGB panels. The printer ships extremely well packed with multiple protective films, though this adds complexity to setup. Users appreciate its support for high-speed resins and its suitability for intricate models. However, some found the assembly process cumbersome due to misaligned protective films and inconsistent power supply accessories. It's best suited for users seeking precision over large build volumes.

Strengths
  • — Features a mono light engine for better resolution and light energy compared to standard RGB-tinted panels
  • — Well-packed with protective films and accessories, ensuring safe shipment and setup
  • — Supports high-speed printing with Anycubic's High Speed Resin, offering faster print times
Watch-outs
  • — Power cord shipped with European plug; lacks standard three-wire connector in included accessories
  • — Instructions are light on safety aspects and lack clarity for some assembly steps

Phrozen's Sonic Mega 8K S is a large-format LCD printer that strips out expensive components to reduce cost while maintaining premium standards. Tom's Hardware praised its construction and reliability, though reviewers noted that its print quality is less sharp than expected due to 43-micron pixels spread across a 15-inch screen. The printer's 330x185 mm build area and 8K resolution are highlighted as key specifications. This product is best suited for users seeking a robust, reliable printer rather than maximum resolution. Those expecting ultra-sharp detail comparable to 4K or higher resolution printers may find it underwhelming.

Strengths
  • — Largest mono LCD in Phrozen's range, with a 330 x 185 mm build plate
  • — Quoted at 600 layers per hour, quick for a plate this size
  • — Built-in resin drip hanger and lift-up lid make large prints less messy
Watch-outs
  • — Print quality comparable to smaller resolution printers like the Sonic Mini 4K with 35-micron pixels
  • — Pixels are 43 microns, making it less sharp than expected for an 8K resolution
