According to Fabbaloo's Kerry Stevenson, the printer arrives with exceptionally tight packaging, with no shifting during transport, marking it as one of the best-packed shipments encountered. The device features a build volume of 153.4 x 87 x 165 mm, which is smaller than typical FFF printers but well-suited for detailed small-scale printing. The ultra model incorporates a 10K 7 monochrome LCD with a resolution of 9024 x 5120 pixels and 17 x 17 μm per pixel, enabling precise micro-detail reproduction. The design includes a protective film system for the light engine's glass plate to prevent resin curing and potential damage during scraping, a feature noted in both Fabbaloo's hands-on review and the Anycubic Wiki maintenance guide.

The printer's construction includes a 4.3-inch touchscreen, a significant upgrade from the 2.8-inch display on the standard model, and it features improved software with friendlier menus and interface options. The build plate is designed with etchings that improve adhesion, and the device ships with a protective film that must be removed before use. However, the assembly process revealed some inconsistencies, such as the inclusion of a European power plug in one shipment, which required users to source a compatible cable. The device also includes a protective film that must be carefully aligned, though instructions lack clear hole references, causing some confusion during setup as noted in the Fabbaloo review.

Real-World Performance

The Photon Mono 4 Ultra demonstrates impressive performance for its size and target use case. Fabbaloo's hands-on Part 1 covers the Photon Mono 4 Ultra's design and setup rather than print results. The machine's ability to handle complex geometry, such as a detailed Mayan Calendar Wheel, was particularly impressive. The ultra-high resolution of 17 x 17 μm per pixel allowed for 0.08mm layer lines that were barely visible under a microscope, indicating the printer's capability to handle micro-detail work beyond the typical range. The use of Anycubic's High Speed Resin allowed for peak speeds of 120 mm/h with standard resin at 0.1mm layer height, significantly faster than the 80 mm/h for standard resin, according to the 3DWork.io review.

The printer's light engine uses an advanced COB light source with a Fresnel lens, which improves accuracy to between 0.01 and 0.05 mm and enhances uniformity. This upgrade over the standard LighTurbo matrix used in the base model is a key differentiator. The ACF film used in the Ultra model reportedly minimizes adhesion, allowing for smoother peeling and higher printing speeds. The software's support structure generation improved significantly in version 3.5, though manual inspection is still recommended for critical prints.

No droops on small figurine parts

Reviewers consistently praised the printer's print quality and detail reproduction capabilities, particularly for small-scale gaming accessories and figurines.
