The Anycubic Photon Mono M7 Pro (prosumer) and Elegoo Saturn 4 Ultra (professional) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. Both are enclosed MSLA resin printers with automatic calibration. The Saturn 4 Ultra costs $87 more and gets you support for 8K Resin; the Photon Mono M7 Pro answers with 17% more build volume and support for Plant-Based Resin.
First-generation product — no release history to base predictions on
Best for: Serious hobbyists, miniature studios, and prosumer resin users who need 14K resolution, a large build volume, and automated resin management — and who are prepared for the post-processing workflow.
Full details →Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Miniature painters, jewelers, dental technicians, and designers who need micron-level detail that FDM printing cannot achieve — and who are prepared for the post-processing workflow of resin printing.

The Photon Mono M7 Pro was released on Jun 15, 2024, 880 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
The Saturn 4 Ultra was released on Jan 23, 2025, 658 days ago. Its previous release cycle ran about 450 days; it is now 208 days past that point and no successor has been announced.
On timing alone, the Photon Mono M7 Pro is the safer buy right now — it has no release history pointing to a successor yet, while the Saturn 4 Ultra is 208 days past its ~450-day cycle with no successor announced.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Photon Mono M7 Pro lists at $562 and the Saturn 4 Ultra at $649 — $87 apart, so the Saturn 4 Ultra costs 15% more.
Per litre of build volume, that works out to $87 for the Photon Mono M7 Pro versus $118 for the Saturn 4 Ultra — the Photon Mono M7 Pro is both cheaper and roomier, so it wins on value outright.
This one is close on paper. If you will stick to materials both printers list (Standard Resin, High-Speed Resin, Water-Washable Resin and ABS-Like Resin), save the $87; if you need 8K Resin, the Saturn 4 Ultra earns its premium. The Photon Mono M7 Pro also brings 17% more build volume and support for Plant-Based Resin.
How we judge timing and deals: read our methodology →
The 14K monochrome LCD delivers exceptional detail at 16.8µm — sharper than most consumer resin printers and ideal for miniatures, dental models, and jewelry masters.
An integrated peristaltic pump monitors resin levels and automatically refills from an external bottle, while built-in vat heating maintains optimal resin temperature — features previously found only on industrial machines.
The M7 Pro's self-leveling floating build plate eliminates manual bed tramming entirely — set up once and never level again.
The Saturn 4 Ultra 16K's 16K LCD delivers detail that FDM printers cannot match — ideal for miniatures, jewelry masters, and precision engineering prototypes.
Monochrome LCD screens cure resin in 1-3 seconds per layer, dramatically faster than older RGB screens.
212×118×220 mm is large for a resin printer — enabling batch printing of miniatures or larger single-piece models.
