Precise 12K resin printer for detailed models

ELEGOO Saturn 4 brings top-tier 12K resolution to a 10" mono LCD (11520×5120 px) with XY accuracy of 19×24 μm. The large build volume of 218.88×122.88×220 mm lets you print robust prototypes and batches of miniatures with sharp edges and smooth surfaces. Automatic leveling and intelligent mechanical sensors simplify first-time setup and daily operation.

Why choose Saturn 4

• 12K mono LCD for exceptional detail, protected by 9H tempered glass.
• COB light source + collimating Fresnel optics (405 nm) with high field uniformity and low angle deviation for even exposure.
• One-click auto-leveling and self-diagnostics for worry-free print startup.
• Mechanical sensor: residue detection, resin shortage alarm, and leveling failure warning.
• Practical design: flip-up cover, quick-release build plate, dual vat pour spouts, drip tray, and replaceable vat lock.
• PFA release film for easy part separation and a laser-engraved build plate for reliable adhesion.

Speed, reliability, and cooling

Maximum print speed up to 70 mm/h and Z-axis accuracy of 0.02 mm save you time without sacrificing quality. Heat dissipation is handled by 4 copper heat pipes and a quiet fan, keeping the printer stable even during long jobs.

Connectivity and software

Control is via a 3.5" resistive touchscreen; the printer supports offline printing from USB. Recommended slicers: CHITUBOX and Voxeldance Tango — easy processing of STL/OBJ files and parameter optimization for 12K quality.

Compatible materials and accessories

Saturn 4 works with common 405 nm resins (standard, ABS-like, water washable, plant-based). For a more comfortable environment, it’s compatible with the Mars Mate air purifier (activated carbon filter removes up to 95% of TVOC).
