Is the Elegoo Saturn 4 Ultra any good?

Yes — the Elegoo Saturn 4 Ultra is generally a very good mid-size resin 3D printer, especially if you want high-detail miniatures, figures, jewelry prototypes, or small engineering parts without jumping to a much more expensive machine.

Best take: it’s a strong buy if you’re comfortable with resin printing’s mess, safety needs, and post-processing. Its main appeal is that it combines a large-enough build volume, very fine detail, fast peel/release-style printing features, and convenience upgrades like automatic setup/monitoring features depending on the exact package/firmware version.

I’d buy it if you want:

• Sharp detail for tabletop minis, busts, terrain details, and display models
• A larger plate than small entry-level resin printers
• Faster resin printing than older lift-only machines
• A more automated experience than basic budget resin printers

I’d hesitate if:

• This is your first 3D printer and you don’t want to handle toxic liquid resin, gloves, ventilation, washing, and curing
• You mostly print large functional parts — an FDM printer is usually better
• You need a silent, odor-free, office-friendly machine
• You already own a recent Saturn-class 8K/12K resin printer and don’t need the speed/convenience upgrades

Bottom line: the Saturn 4 Ultra is one of the better enthusiast resin-printer picks in its class, but budget for a wash/cure setup, PPE, resin, spare FEP/release film, screen protectors, and proper ventilation. Before buying, verify the exact current model listing — Elegoo has released similar Saturn variants, and features can differ by version.
