How much space does it need?

The Elegoo Saturn 4 measures 327.4 × 329.2 × 548 mm (12.9 × 13 × 21.6 in) for a 218.88 × 122.88 × 220 mm (8.6 × 4.8 × 8.7 in) build volume: the dashed box is the printer, the solid cube the nominal build volume, about 10% of the machine’s volume. Add room for opening the cover, handling the vat, cables and ventilation.

Which projects is it for?

The Saturn 4 is an MSLA resin printer with a 10-inch monochrome 12K screen and a 218.88 × 122.88 × 220 mm build volume per Elegoo. This larger format than the Mars line suits batches of figurines, mid-size parts, and taller vertical prints thanks to the 220 mm of headroom.

One-click automatic leveling and a pre-print self-check, advertised by Elegoo, keep setup simple despite the larger plate.

Materials and setup

The printer runs compatible 405 nm UV resins, each with its own profile and post-processing steps per Elegoo. The COB light source paired with a Fresnel collimating lens aims for 92% light uniformity advertised across the entire build area.

The dual-spout resin tank makes pouring and draining easier per Elegoo, but Elegoo specifies that the Saturn 4 is not compatible with flexible build plates, which risk throwing off automatic detection and damaging the LCD screen.

What the bundle includes or not

The box includes the printer, build plate, resin tank, a USB drive, a mask, and gloves per Elegoo's "What's In Box" list, with further items not detailed, 6 and up in total. The exact contents should be checked on the retailer's listing before buying.

The flip-up cover makes the build plate easier to access, but the printer has neither Wi-Fi nor a built-in monitoring camera per the spec sheet.

Alternatives to compare

For a faster print speed on the same screen format, the Saturn 4 Ultra adds tilt-release technology and an AI camera. For a tighter budget on a smaller plate, the Mars 5 remains an entry-level option.

The resin printer buying guide and the resin materials guide help prepare post-processing for this plate size.

Frequently asked questions

What is the build volume of the Elegoo Saturn 4?

Elegoo lists a 218.88 × 122.88 × 220 mm (8.6 × 4.8 × 8.7 in) build volume (width × depth × height). That is the largest theoretical part size; supports, brim and orientation reduce the usable space.

How big is the Elegoo Saturn 4?

According to Elegoo, the Elegoo Saturn 4 measures 327.4 × 329.2 × 548 mm (12.9 × 13 × 21.6 in) (width × depth × height) and weighs 13.5 kg (29.8 lb). Leave extra clearance for opening the cover, handling the vat, cables and ventilation.

What resolution does the Elegoo Saturn 4 offer?

Elegoo lists a 10-inch 12K LCD. Finer pixels help with miniature detail, but supports, resin and washing still decide the final surface.

Is the Saturn 4 faster than the Mars lineup?

The speed Elegoo advertises is a maximum of 70 mm/h, comparable to the Mars 5, on a noticeably larger 218.88 × 122.88 × 220 mm plate.

Can you install a flexible build plate?

No, Elegoo explicitly states that flexible build plates are not compatible with the Saturn 4 and can disrupt automatic detection or damage the screen.

Does the machine have a monitoring camera?

No, Elegoo's listing does not mention a camera on the Saturn 4; that feature appears on the Saturn 4 Ultra in the same lineup.
