Sharper detail, bigger builds: Mars 3 is ELEGOO's first desktop mSLA 3D printer built around super-high precision. A 6.66 inches mono LCD with Ultra 4K HD resolution pushes the XY resolution to 35μm — 30% finer than Mars 2 — while the build volume grows by 37%. That combination is what makes the output look the way it does.
Release film 2.0: Thinner supports and delicate details survive the peel far more often thanks to lower release tension, so models loaded with fine geometry come off the plate intact. Success rate on detailed prints improves noticeably.
Reworked light source: 36 highly integrated LED lights sit behind a new COB lens with a free-form surface. UV illumination uniformity tops 90%, and printing accuracy climbs with it.
Cooler running LED unit: ELEGOO Mars 3 routes copper tubes through the heat sink unit and pairs them with a high-quality cooling fan. Heat dissipation improves, and light decay stays under 5% after 6000 hours of printing — which is how the UV LEDs last longer.
Chitubox Pro included: Your Mars 3 ships with a 1-year free trial of the Chitubox Pro slicer, worth 169USD. Automatic supports and model repair tools are part of the package, useful whether you run a professional 3D printing lab or you're just starting out. Lychee Slicer now works with Mars 3 as well.
