Anycubic Photon Mono 4 Ultra

Anycubic Photon Mono 4 Ultra: 10K Detail and COB Speed in a Desktop Resin Printer

The Anycubic Photon Mono 4 Ultra is the most advanced model in the Photon Mono 4 lineup and one of the most capable desktop resin 3D printers in its class. It combines a 7'' mono LCD screen with 10K resolution, a COB light source with Fresnel lens, and an intelligent error detection system to deliver sharp prints, fast cycle times, and a high success rate. It's designed for makers, miniature and scale model hobbyists, jewelry designers, dental professionals, and anyone looking for a genuine quality upgrade over the standard Photon Mono 4 without stepping up to a large-format machine.

With a build volume of 153.4 × 87 × 165 mm, it's compact enough to fit on a desktop yet tall enough to print busts, articulated figures, or full batches of miniatures in a single run. If you're coming from a 4K or 6K printer, the difference in sharpness is immediately obvious from your very first print.

Precision, Screen, and Light Source

At the heart of the Photon Mono 4 Ultra is its 7-inch 10K monochrome LCD, with a resolution of 9024 × 5120 pixels and a pixel size of just 17 × 17 µm on the X and Y axes. That pixel density means cleaner edges, sharper fine textures, and minimal aliasing — ideal for scales, fabric, hair, and jewelry settings.

The biggest upgrade over previous models is the COB (Chip On Board) light source paired with a Fresnel lens. This system focuses UV light within a narrow 3° angle, eliminating stray light that blurs fine details and ensuring over 90% light uniformity across the entire print area. With an intensity of ≥3500 µW/cm², curing is consistent from center to corners — which shows in the evenness of thin walls and the crispness of top-layer details.

On the Z axis, a single linear rail delivers a positioning precision of 20 µm, keeping dimensional accuracy within ±0.01–0.05 mm. The result is excellent repeatability both within a print and across multiple batches.

Smart Features and Automation

The Photon Mono 4 Ultra isn't just about optics — it includes automation features that reduce print failures and wasted resin.

• Intelligent failure detection: a sensor monitors the print for anomalies such as cracking, model detachment, or layer separation. When an issue is detected, the machine pauses the job and alerts the user, preventing FEP damage or resin waste from a failed print.
• Light uniformity algorithm: compensates exposure layer by layer to maintain consistent sharpness throughout the entire print.
• ACF release film: reduces peel force on each layer, enabling higher print speeds and lowering the risk of layer separation or surface artifacts.
• Power loss recovery: if power is interrupted, the print can resume exactly where it left off without losing your work.
• Assisted leveling: the laser-engraved aluminum build plate makes quick leveling easy and ensures highly reliable first-layer adhesion.

Everything is controlled through a 4.3'' touchscreen with a clean, intuitive interface, and files can be sent via USB or Wi-Fi — great for launching jobs wirelessly without fumbling with cables.

Design and build quality

The Photon Mono 4 Ultra features Anycubic's classic compact tower form factor, measuring 231 × 236 × 430 mm and weighing just 5 kg — easy to place on any desk and move around as needed. The laser-engraved aluminum build plate provides excellent first-layer adhesion, while the resin vat (≤0.39 L capacity) is designed for easy filling and cleaning. The enclosure lid shields your prints from ambient light and contains odors — a real plus if you're printing in a shared or living space. The ACF release film is user-replaceable, keeping long-term maintenance simple and affordable.

Specifications

Compatible resins and software

The Photon Mono 4 Ultra works with virtually any 405 nm UV resin on the market, but performs at its best with Anycubic resins — particularly High Speed Resin 2.0, which unlocks the full 120 mm/h print speed. If you want easier post-processing, water-washable resins let you clean prints without isopropyl alcohol. For functional or technical parts, check out the range of tough and engineering resins, and for display models and visual prototypes, clear and transparent resins deliver stunning results.

On the software side, the printer comes ready to use with Photon Workshop, Anycubic's official slicer, but it's fully compatible with Chitubox and Lychee Slicer as well — so you can keep your existing workflow and saved profiles without any hassle.

Who is it for?

The Photon Mono 4 Ultra is an ideal choice for miniature painters and wargamers who demand professional-grade detail, jewelry designers who need tight tolerances and crisp edges, hobbyists and makers looking for 10K print quality at a competitive price point, and small studios or workshops that rely on consistent, repeatable results. If you're upgrading from the standard Photon Mono 4 or a 4K/6K machine, the jump in sharpness and print success rate will be immediately noticeable.

Workflow: Print, Wash, and Cure

Resin printing involves three stages. First, you print: slice your model in Photon Workshop, Chitubox, or Lychee Slicer and send the file via USB or WiFi. Next, you wash the part to remove uncured resin — either with water (if you're using water-washable resin) or with isopropyl alcohol and post-processing supplies. Finally, you cure the part under UV light to reach its full hardness. To streamline these last two steps, a wash and cure station saves you time and noticeably improves surface finish.

Recommended Accessories

To get the most out of your Photon Mono 4 Ultra and extend its lifespan, we recommend keeping screen protectors on hand — they shield the LCD from resin splashes — along with replacement film from the FEP, nFEP, and ACF section for vat maintenance, and IPA and post-processing supplies for a thorough clean. If maximum detail is your priority, also check out our high-definition resins.

Comparison with the Standard Model

Compared to the standard Anycubic Photon Mono 4, the Ultra brings several key upgrades: it replaces the LighTurbo light source with a more precise and uniform COB light source + Fresnel lens, boosts print speed from 70 mm/h up to 120 mm/h with high-speed resin, adds smart failure detection, uses the new ACF release film, and includes WiFi connectivity. Both models share the same 7'' 10K screen and build volume — so if you're after more speed, greater reliability, and better light uniformity, the Ultra is the obvious choice.

Frequently Asked Questions

What resolution does the Anycubic Photon Mono 4 Ultra have?

It features a 7-inch mono LCD screen with 10K resolution (9024 × 5120 pixels) and a pixel size of 17 × 17 µm, delivering an exceptional level of detail for miniatures and jewelry.

How fast does it print?

It reaches up to 120 mm/h using Anycubic's High Speed Resin 2.0 at 0.1 mm layer height, and up to 80 mm/h with standard resin, thanks to its COB light source and ACF release film.

What resins are compatible?

It works with any 405 nm UV resin, including Anycubic resins, water-washable resins, clear resins, and tough resins. For maximum print speed, Anycubic High Speed Resin 2.0 is recommended.

Do I need isopropyl alcohol to clean prints?

It depends on the resin. Standard resins require isopropyl alcohol for washing; water-washable resins can be cleaned with water alone, no solvents needed.

What slicing software is supported?
