The ELEGOO Saturn 4 Ultra 16K, now available for $493.99 (regularly $649.99), produces prints with factory-level precision. Featuring a 10-inch 16K monochrome LCD display, a heated resin tank, and smart upgrades such as tilt-release technology, this machine is designed to impress right out of the box.
Inside the package you’ll find a resin tank, build plate, power adapter, USB drive, gloves, masks, scrapers, and a full tool kit for assembly. Setup is simple since the printer arrives almost fully pre-assembled. After removing a few transport bolts, attaching the build plate, and connecting the power brick, you’re nearly ready to start printing. The 4-inch capacitive touchscreen handles the rest, guiding you through setup steps like choosing your language, connecting to Wi-Fi, and applying firmware updates if needed.
The 10-inch 16K LCD screen offers a resolution of 15120 × 6230 pixels, which translates to 14 × 19 microns—finer than a human hair. A COB UV light source paired with a Fresnel lens provides 25% more output compared to earlier models at 5 mW/cm², allowing for faster curing and a top print speed of 150 mm/h. For example, a detailed bust printed in just 6 hours, a task that used to take about 8 hours on older resin machines. The build volume of 211.68 × 118.37 × 220 mm also gives you generous space for larger projects.
One standout improvement is the heated resin tank, which keeps resin at 30°C for consistent flow and reliable layer adhesion, particularly useful in cooler environments. The tilt-release system is another advantage, gently peeling prints from the tank instead of pulling them straight up, which reduces stress, deformation, and print failures.
Although resin printing can be messy and hazardous, ELEGOO has added thoughtful safety and convenience features. The printer pauses automatically if temperatures exceed 80°C and resumes seamlessly after a power outage. A drip tray helps contain spills, while dual pour channels simplify resin removal. Safety gear is still essential, gloves and masks remain non-negotiable, but the process feels more controlled.
The included USB drive comes loaded with ELEGOO’s SatelLite 3D slicer and Chitubox, both intuitive tools for slicing and adjustments. Connectivity is smooth with options for Wi-Fi and USB, while a built-in 1920 × 1080 AI camera keeps watch on prints in real time.
