The cutting-edge technologies applied in the Mars 4 Ultra printer enable the creation of intricate and detailed models with exceptional clarity and precision.

Quality components for reliable performance

Protected by a replaceable robust 9H hardness tempered glass, the mono LCD ensures durability against daily wear and tear while maintaining optimal performance. This solution also makes the screen easier to clean and prevents the ingress of resin or any other liquid that could cause deterioration. The printer's fast printing capabilities are remarkable, achieving speeds of up to 150 mm/h with ACF release liner film, enabling swift and efficient production of high-quality models.

The ACF film is one of the features that distinguish the Mars 4 Ultra from its predecessors equipped with FEP film, such as the Mars 4. While FEP film characterized by non-stick properties and chemical resistance is a more generic material used in a wide variety of resin 3D printers, ACF film is specialized to enhance the printing success rate at higher speeds by reducing release tension between the cured resin and the film.

The COB light source and Fresnel collimating lens deliver a consistent 405 nm wavelength beam across the entire build area with less than a 5-degree light angle and 92 % light uniformity. This guarantees uniform curing, resulting in smooth and even surface finishes. Enhanced heat dissipation through a large cooling fan and heat-conducting copper tubes near the light source improves performance and extends the printer's service life.

Constructed with an all-metal body, the printer is durable and stable, capable of withstanding frequent use. Its sleek design adds an aesthetic touch to any workspace. Moreover, the printer's internal components are protected by design features such as the raised step on the mid-plate to prevent resin spillage and the screw end caps on the build platform screws for easier cleaning during maintenance.

The 4-point hassle-free leveling system streamlines setup, ensuring consistent and perfect prints without the need for repeated leveling. Additionally, the laser-carved surface of the build plate enhances adhesion, especially for larger models. The adoption of a linear guide rail structure in the Z-axis guarantees precise (0.02 mm) and stable movement, resulting in smooth and detailed surfaces on printed models.

User-friendly and safe

The user-friendly interface includes a 4-inch HD IPS touch screen supporting 12 languages, ensuring ease of operation for users of varying expertise levels. The printer comes with Voxeldance Tango Slicer and supports open-sourced GOO slice file formats compatible with third-party slicing software. Furthermore, the Voxeldance Tango software enables 3 printing modes: static (predefined parameters), dynamic (real-time speed adjustment), and high-speed mode.
