Elegoo Saturn 2

The Elegoo Saturn 2 is a mid-size resin printer from 2022 built around a 10-inch 8K masking LCD and a 219×123×250 mm build volume. It's discontinued — the Saturn 4 and Saturn 4 Ultra took its slot — so a new unit only turns up as leftover stock. People bought it for the mix of a big plate and fine detail: miniatures, busts and master models.

The 7680×4320 panel works out to a 28.5 μm pixel, roughly half the 50 μm of the first Saturn. A COB light source with a Fresnel collimating lens keeps the beam close to vertical, so exposure stays even across the full ten inches. The Z axis rides two linear rails and a trapezoidal lead screw at 0.00125 mm steps, layers run 0.01 to 0.2 mm, and speed is 30–70 mm/h. There's 9H tempered glass over the panel, a PFA release liner, and a carbon filter on a dedicated 24 V port — it looks like USB, so don't stick a thumb drive in it.

Pros

• The 219×123×250 mm volume was the tallest Saturn of its time: a large bust fits whole, or a full tray of 32 mm minis in one run
• The Fresnel lens evens out exposure at the panel edges — Tom's Hardware logged zero failed prints across the whole review
• 9H tempered glass over the panel: spilled resin wipes off the glass instead of killing a $100 masking LCD
• The power button moved to the front — on the Saturn S the switch sat around the back, out of easy reach
• A removable plug in the UV lid lets you duct the fumes outside instead of circulating them around the room
• PFA film is tougher than standard FEP and cuts peel force, so parts release without a hard jerk

Cons

• The bundled carbon filter doesn't clear the smell entirely — Tom's Hardware still noticed lingering resin odor with it running
• The UV array keeps firing with the lid removed, so it's easy to expose eyes and skin while servicing the machine
• Leveling is manual, two bolts against a card shim, and you redo it after moving the printer
• It's discontinued: the LCD, vat and film are consumables, and official spares are getting scarce

The Saturn 2 suits anyone printing tabletop minis in batches, busts, dioramas and casting masters. A beginner can handle it: nothing to assemble, leveling takes five minutes. Today it's a used-market buy — for a new machine with a comparable plate, look at the Saturn 4 or Saturn 4 Ultra.

Bottom line: in 2022 this was the most balanced large resin machine Elegoo sold — a big plate and a 28.5 μm pixel for sensible money. The risk now isn't the spec sheet, it's supply: check you can source a replacement screen and film first.
