Elegoo has revealed some big price cuts across its line-up, top of which is the Saturn 4 Ultra, now $369 (was $524) - a huge $155 saving on a feature-packed resin printer in the company's Easter sale.

And in the UK, the Saturn Ultra 4K is down to £299 (was £443) in Elegoo's sale. The printer's tilt release technology separates each finished layer cleanly from the film, helping prints release smoothly and allowing speeds up to 150mm/h. Projects finish quicker as a result, without needing constant attention.

3D printers are one of the most exciting tools for creators who want to turn digital ideas into physical objects right at home, and modern resin printers deliver levels of detail that once felt out of reach for hobbyists and professionals. In our Saturn 4 Ultra review, we said it "impresses with its high resolution, ease of use, and smart features, making it a great choice for anyone looking to print detailed models."

Clear detail is easier to achieve with the 10-inch 12K mono LCD screen, which controls where light hits the resin using tiny pixels that help form sharper edges and smoother surfaces on every layer.

With a resolution of 11520 x 5120 and an XY resolution of 19 x 24μm, it produces sharp edges and smooth surfaces.

Lighting inside the printer stays consistent using a 405nm COB light source paired with a Fresnel collimating lens. With 92% light uniformity across the screen, each layer cures evenly, which helps reduce printing errors and keeps finished models looking consistent from top to bottom.

Setup feels far less intimidating than older machines because automatic leveling handles one of the trickiest early steps. A built-in self-check runs when powered on, so you can unbox the printer, switch it on, and begin printing without digging through complicated adjustments or manuals.

There’s also an AI camera that keeps watch during prints, giving real-time updates and spotting problems before they ruin a model.

Extra safeguards like residue detection, resin shortage alerts, and leveling warnings help protect the printer while keeping beginners informed about what's happening throughout the entire creation process.
