ELEGOO Mars 4 Ultra 9K: A High-Precision MSLA 3D Printer for Professionals and Hobbyists

The ELEGOO Mars 4 Ultra 9K stands out as a compelling addition in the world of MSLA 3D printers, designed to meet the needs of a broad spectrum of users ranging from beginners to advanced professionals. Released in 2023, this machine embodies a blend of professional-grade features and accessibility, tailored for applications such as prototyping, dental modeling, miniatures, and jewelry making. On paper, the Mars 4 Ultra's specifications reveal a carefully engineered device that promises high print accuracy, fast printing speed, and reliable build volume, all while maintaining a user-friendly experience.

Detailed Specs & Features

According to its engineering data, the Mars 4 Ultra is a prebuilt MSLA printer weighing 14.33 pounds with a compact form factor of 9.05 inches in width and depth, and 17.32 inches in height; quite manageable for desktop use. Its build volume of 127.2 cubic inches allows printing of moderately sized models, measuring 3.06 by 6.03 by 6.89 inches in width, depth, and height, respectively, which is fairly generous for resin printers in this price range. This volume is supported by a meticulous layer resolution range, from a minimum of 0.01 mm to a maximum of 0.2 mm, enabling exceptionally detailed prints.

The 9-inch touchscreen display with a screen resolution of 9K affords precise control over print settings, indicative of its professional orientation. The power system operates on a reliable external supply rated for 100-240 volts, consuming 24 watts during operation, complemented by an energy-saving mode which boosts efficiency.

User Experience & Performance

Design & Build

The Mars 4 Ultra's design integrates a Z-axis frame type enclosed in a closed shell, which aids in consistent curing and reduces environmental interference; a key factor for maintaining stable print quality. Carbon air filtration further enhances safety during resin curing, demonstrating adherence to safety certifications including CE, FCC, and RoHS. The sturdy build plate uses a flexible etched surface, which is removable, facilitating easy print removal without damage. Manual bed leveling is the norm here, which, while more labor-intensive than automatic systems, allows users fine-grained control over the first layer.

Performance

This printer offers an official and effective maximum print speed of 70 millimeters per hour. The print accuracy rating of 18 microns emphasizes the Mars 4 Ultra's capability to produce highly detailed models. Operating noise level peaks at 50 decibels, akin to a quiet conversation.

Connectivity & Software

Connectivity options are robust, with both USB and Wi-Fi allowing easy file transfer and networked operation. For software, the Mars 4 Ultra supports popular slicers such as LycheeSlicer and CHITUBOX.

Extra Features

Carbon air filtration for air quality control is a notable plus for safety-conscious users. Tool-free maintenance and the availability of spare parts plainly indicate that the printer is designed with long-term usability in mind. On the downside, features like auto bed leveling, power-loss recovery, and filament runout sensors are missing.

Price & Value for Money

Priced at $192 at the ELEGOO official store, the Mars 4 Ultra offers an excellent value proposition, especially considering its high-resolution screen and substantial build volume. Given its warranty period of 1 year and energy-efficient design with wide voltage compatibility, this printer is cost-effective for both hobbyists and professionals.

Verdict

Rating: Based on the specifications and overall feature set, we believe the ELEGOO Mars 4 Ultra deserves 4.3 out of 5.
