A compact MSLA resin printer with a monochrome 9K screen and a 153.36 × 77.76 × 165 mm nominal build volume.
In short The Elegoo Mars 5 Ultra is an resin (MSLA) 3D printer with a 153.36 × 77.76 × 165 mm (6 × 3.1 × 6.5 in) build volume. Elegoo claims a 7-inch 9K LCD, 18 µm XY resolution and up to 150 mm/h; the printer measures 260 × 268 × 451.5 mm (10.2 × 10.6 × 17.8 in) and weighs 8.8 kg (19.4 lb).
Documentary analysis · Not personally tested
Why consider it?
A second documented resin format to compare with the larger Saturn 4 Ultra 16K.
What to verify
The cover does not replace a suitable resin workspace. Plan washing, curing and consumables.

How much space does it need?
The Elegoo Mars 5 Ultra measures 260 × 268 × 451.5 mm (10.2 × 10.6 × 17.8 in) for a 153.36 × 77.76 × 165 mm (6 × 3.1 × 6.5 in) build volume: the dashed box is the printer, the solid cube the largest theoretical part, about 6% of the machine’s volume. Add room for the spool or multicolor unit, cables and ventilation.

Read the Elegoo Mars 5 Ultra specification analysisWhich projects is it for?
The Mars 5 Ultra is an MSLA resin printer with a monochrome 9K screen and a 153.36 × 77.76 × 165 mm build volume per Elegoo's product page. That compact footprint suits miniatures, figurines, and highly detailed parts, where resin captures fine surface detail that FDM struggles to match.
Resin printing also means a different workflow than a filament printer: washing, curing, and handling chemicals become part of the routine, which matters as much as the build volume when choosing this machine.
Materials and configuration
The printer runs compatible 405 nm UV resins, each with its own profile and post-processing steps per Elegoo. The manufacturer recommends following the profile supplied for the chosen resin rather than reusing settings from another machine.
Only one resin can be loaded at a time: there is no automatic color or material switching on this model, unlike some multicolor FDM printers in the catalog.
What the bundle includes or not
Elegoo's product page describes a cover on the machine, but that is not a substitute for a proper resin workspace: a wash-and-cure station (often sold separately), isopropyl alcohol, gloves, and a ventilated room are still needed to handle resin safely.
Before buying, check exactly what the specific listing includes (resin included or not, wash/cure station included or not) rather than assuming it from the product photo alone.
Before finalizing a purchase, compare the Mars 5 Ultra's spec sheet and manual from the manufacturer rather than relying only on the product photo, especially for the exact box contents (resin, wash-and-cure station, accessories). Warranty terms and after-sales support can also differ between the official store and a third-party retailer, worth checking before comparing two listings. Since resin printing involves ongoing consumables, it also helps to price out extra resin, gloves, and film replacements as part of the overall setup rather than treating the machine's listing as the full cost of getting started.
Alternatives to compare
For a larger build plate or a different resolution within the same brand, the Saturn 4 Ultra 16K is the most direct comparison. The resin printer buying guide covers the criteria for choosing between the two formats based on what you print most, and the Elegoo page places the Mars 5 Ultra within the rest of the manufacturer's lineup.
The resin post-processing guide walks through the washing and curing steps to plan for after every print, regardless of the model you choose.
