Capable of reaching a maximum printing speed of 150 mm/h, this printer incorporates advanced technologies to produce highly detailed and intricate models. It offers a substantial build volume of 218.88 x 122.88 x 220 mm, allowing for the creation of sizable and precise prints with most resin types available on the market - water-washable, standard, ABS-like, plant-based, etc.

Speed and precision

The Saturn 4 Ultra 3D printer features the most high-end components to provide ultimate quality and durability. Constructed with a durable metal frame, the printer maintains its precision and performance even after millions of printing layers. The mono LCD screen is safeguarded by a durable 9H hardness tempered glass, which can be replaced if needed. This protection ensures the screen withstands daily use while retaining its high performance. Additionally, the tempered glass makes cleaning simpler and prevents resin or other liquids from seeping in and causing damage.

The Saturn 4 Ultra printer utilizes a PFA (Perfluoroalkoxy) release film known for its excellent non-stick qualities, thermal stability, and chemical resistance. This film serves as a protective layer, preventing photopolymer resin from sticking during printing. Its non-stick properties ensure easy separation of cured resin layers from the vat, leading to smoother releases, minimizing damage to printed objects, and extending the vat's lifespan while maintaining consistent print quality. Great print adhesion and easy part removal are also ensured by the high-quality laser-engraved build plate.

The COB light source of the Saturn 4 Ultra printer operates at 405 nm and, when paired with a Fresnel collimating lens, achieves an ultra-low astigmatism coefficient of 0.5 %. It offers remarkable field uniformity of 92 % and maintains precise angle deviation control under 5° on the build surface, ensuring accurate and consistent printing with fine details and smooth finishes. Uniform curing is assured, providing a flawless surface quality. Enhanced performance and extended printer longevity are achieved through effective heat dissipation, thanks to a cooling fan and four copper heat tubes positioned near the light source.
