Elegoo Mars 5 Ultra Review – Specs, Speed and Print Quality

Build Volume and Printing Capabilities

One of the first things that surprises people about the Elegoo Mars 5 Ultra build volume is how compact it is compared to its siblings. At 153.36 x 77.76 x 165 mm, it’s notably smaller than the Mars 4 Ultra, which offers a build volume of 218.88 x 122.88 x 220 mm. That is a meaningful difference on paper — but in practice, it tells a more interesting story.

This printer is purpose-built for smaller, highly detailed work. Think tabletop gaming miniatures, intricate jewelry designs, small mechanical parts, and detailed figurines. For these use cases, the Mars 5 Ultra’s build volume is not a limitation — it’s a feature. The smaller footprint means the machine can maintain tighter tolerances and deliver more consistent results across the entire print area.

And the build volume is still genuinely useful for batch printing. You can easily fit a full squad of 28mm-scale tabletop miniatures on a single plate, complete with their bases, supports, and accessories. For anyone running a small creative business printing models-on-demand or producing resin parts in small runs, this printer is well-suited to the task.

The build platform itself features a diamond-plate style textured surface that provides excellent adhesion. The quick-release lever mechanism allows you to snap the platform off and on without tools, which makes the transition between printing and post-processing much smoother. Elegoo has also included a plastic drip tray that sits beneath the vat, catching any stray resin when you remove the build plate — a small touch that makes a big difference in keeping your workspace clean.

What’s also notable is that the printer includes a sealed compartment in its lid designed to accommodate Elegoo’s optional Mini Heater. While the heater isn’t included in the box, the provision for it shows thoughtful design for users who want to print in cooler environments where resin viscosity can become an issue.

Print Resolution and Detail Quality

Here’s where the Elegoo Mars 5 Ultra truly earns its reputation. The Elegoo Mars 5 Ultra resolution — a full 9K screen with 8520 x 4320 pixels and an XY resolution of just 18 microns — is exceptional. To put that in perspective, 18 microns means each individual pixel of UV light curing your resin is only 0.018 millimeters wide. That is extraordinarily fine detail.

For miniature painters and tabletop gamers, this level of resolution means facial expressions on 28mm figures are crisp and paintable. Chainmail rings on fantasy armor read as individual links. The scales on a dragon model have texture and depth. Fine architectural details on terrain pieces come out clean and sharp. It’s the kind of resolution that, until very recently, required printers costing several times more.

The 9H tempered glass screen protector is worth highlighting too. Resin spills are a fact of life, and without protection, they can permanently damage the LCD screen — one of the most expensive components to replace. By covering the screen with scratch-resistant glass, Elegoo has given this printer a meaningful durability upgrade over machines that rely on simple acrylic shields.

The COB light source, with its 92% uniformity rating, plays a huge role in print quality as well. Inconsistent lighting leads to inconsistent curing, which causes artifacts, warping, and failed prints. With near-perfect uniformity, every corner of your build area cures at the same rate as the center — and your prints show it.

Reviewers at Tom’s Hardware awarded the Mars 5 Ultra an Editor’s Choice designation, specifically praising its excellent 9K resolution and the quality it delivers for gaming miniatures. Prints look even better when paired with high-definition resins designed for fine detail work.

Printing Speed and Performance

Speed is one of the headline features of the Elegoo Mars 5 Ultra, and it delivers in a significant way. At up to 150 mm/h, the Elegoo Mars 5 Ultra printing speed puts it among the fastest printers in its class. To understand why this is such an achievement, it helps to know a little about how the printing process works.

In traditional resin printing, the build plate lifts straight up after each layer cures, peeling the model away from the release film. This requires the film to flex and release cleanly, which takes time and creates stress on the model. Earlier printers using standard FEP film were limited to relatively slow speeds to avoid print failures during this peeling process.

The Mars 5 Ultra uses tilt release technology — the same mechanism found in Elegoo’s higher-end Saturn series. Instead of lifting straight up, the vat tilts at approximately a 15-degree angle after each layer. This gradual tilt distributes the peeling force more evenly, allowing the model to separate from the film much faster and with far less stress. This is why the printer can achieve 150 mm/h while using standard PFA film, rather than the more expensive ACF film that other high-speed printers require.

Each layer cures in just 1.5 to 3 seconds, and with the tilt release mechanism working efficiently, the printer barely pauses between layers. The practical result is that prints that would have taken 6 or 8 hours on an older machine can be completed in 2 or 3 hours on the Mars 5 Ultra. For anyone running multiple print sessions per day, that time saving compounds quickly.

The printer also offers two selectable print modes — fast and slow — giving you flexibility to prioritize either speed or additional care for more delicate, complex geometries. For most prints, fast mode delivers excellent results. For extremely fine jewelry or ultra-thin features, slow mode provides extra confidence.

Software and Printer Setup

The Elegoo Mars 5 Ultra setup experience is one of the cleanest in its class. Right out of the box, the process is refreshingly simple: unpack the printer, remove the protective foam, attach the Wi-Fi antenna, place it on a stable flat surface, plug it in, and follow the on-screen guide. The 4.0-inch capacitive color touchscreen walks you through initial configuration including Wi-Fi connection, and the printer will even check for firmware updates automatically and install them on its own.

Auto-leveling is handled by an intelligent mechanical sensor. With a single button press, the build plate descends to the LCD screen and calibrates itself precisely. You don’t need to manually adjust leveling knobs or place paper under the build plate — the machine handles it all. This is a massive convenience, especially for beginners who might otherwise spend an hour troubleshooting failed first layers.

Before every print, the Mars 5 Ultra performs a self-check sequence, inspecting the Z-axis motor, the LCD screen connection, the LED temperature sensor, the mechanical sensor, and even tracking the accumulated usage count of the release film. When that count approaches 60,000 release cycles, the printer sends a reminder to replace the film — a proactive approach to maintenance that prevents unexpected failures mid-print.

For slicing, the printer ships with ChituBox Basic v2.2 on a included USB drive. This is a capable, beginner-friendly slicer that handles hollowing, support generation, and layer preview well. The machine is also compatible with Elegoo’s own SatelLite slicer, which already includes the Mars 5 Ultra profile. ChituManager, a plugin within ChituBox, enables Wi-Fi file transfer and remote monitoring through the built-in camera.

The integrated AI camera allows you to observe print progress in real time from your phone or computer, create time-lapse videos of your builds, and detect early signs of print failure. It’s a genuinely useful feature that gives remote visibility into what’s happening inside the printer — and it comes standard, not as an add-on.

Comparing Mars Generations

So how does the Elegoo Mars 5 Ultra vs Mars 4 Ultra comparison actually play out? It’s an interesting matchup because these aren’t straightforward sequential upgrades — they serve somewhat different purposes.
