Resolution and Print Quality:

At the heart of the ELEGOO Saturn 4 is its impressive 12K Mono LCD screen, boasting a resolution of 11520x5120 pixels. This translates to an incredibly fine XY resolution of 19x24µm, allowing for the production of models with exceptional detail and smooth surfaces. The printer utilizes a COB (Chip on Board) light source combined with a Fresnel collimating lens, achieving 92% light uniformity and an astigmatism coefficient within 0.5%. This advanced lighting system ensures consistent exposure across the build plate, resulting in more accurate and higher-quality prints.

Build Volume and Capacity:

With a generous build volume of 218.88mm x 122.88mm x 220mm, the Saturn 4 provides ample space for larger models or multiple smaller prints in a single session. This capacity makes it suitable for a wide range of applications, from creating detailed miniatures to producing functional prototypes or artistic sculptures.

Intelligent Features:

The Saturn 4 incorporates several smart features to enhance the printing experience:

One-Click Auto Leveling: Using a smart mechanical sensor and springs inside the build plate, the printer can self-calibrate with just one click, eliminating the need for manual leveling.

Intelligent Mechanical Sensor: This feature can detect resin shortages and residues, improving print success rates and extending the printer's lifespan.

Quick Self-Check: Users can initiate a rapid self-check to ensure the printer is functioning normally before starting a print job.

User-Friendly Design:

ELEGOO has implemented several design improvements to make the Saturn 4 more convenient to use:

Advanced Cooling System: Helps maintain optimal operating temperatures for consistent print quality.

Laser-Carved Build Plate: Enhances adhesion of prints to the build plate.

Flip-Top Design: Allows for easy access to the print area and resin vat.

Quick-Release Build Plate: Simplifies the process of removing finished prints.

Easy Resin Pouring: Thoughtful design elements make adding and changing resin less messy.

Replaceable Resin Tank: Allows for quick swaps between different resin types or easy maintenance.

Connectivity and Software:

While not explicitly mentioned in the provided information, it's worth noting that most modern resin printers like the Saturn 4 typically offer USB connectivity for transferring print files. ELEGOO printers are generally compatible with popular slicing software such as ChiTuBox or ELEGOO's own slicing software, allowing users to prepare their 3D models for printing.

Material Compatibility:

The Saturn 4 is designed to work with 405nm UV-curing resins, which are available in a wide variety of colors and properties. This includes standard resins, as well as specialized formulations for strength, flexibility, or specific applications like dental or jewelry casting.

Price and Value:

ELEGOO Saturn 4 offers exceptional value for its features and capabilities. This pricing positions it competitively in the mid-range resin 3D printer market, making high-quality resin printing accessible to a broad audience.

In conclusion, the ELEGOO Saturn 4 12K MSLA Resin 3D Printer stands out as a powerful and user-friendly option for those seeking high-resolution 3D printing capabilities. Its combination of advanced technology, intelligent features, and thoughtful design make it an excellent choice for both newcomers to resin printing and experienced users looking to upgrade their capabilities.

ELEGOO has recently released two new resin 3D printers in their Saturn line: the Saturn 4 and the Saturn 4 Ultra. Both printers offer significant improvements over their predecessors, but they also have some key differences. This essay will explore the similarities and differences between these two models, their features, and their performance.

Similarities:

Both the Saturn 4 and Saturn 4 Ultra share several important features:

Flip-top lid design for easy access

Auto bed leveling function, simplifying setup and maintenance

New latch design for secure build plate attachment

Identical vat design with dual pour spouts

12K mono screen display for high-resolution printing

Same build volume: 218.88mm x 122.88mm x 220mm

COB and Fresnel displays with tempered glass tops

Vertical display orientation

Smart sensors to detect resin levels and debris

Key Differences:

Despite their similarities, there are several notable differences between the two models:

Printing Mechanism:

Saturn 4 Ultra: Features a tilting vat mechanism for faster printing and simplified slicing

Saturn 4: Uses the traditional up-and-down vat movement

Connectivity:

Saturn 4 Ultra: Offers Wi-Fi connectivity for wireless file transfer and remote monitoring

Saturn 4: Requires USB file transfer

Camera:

Saturn 4 Ultra: Includes a built-in camera for remote monitoring and time-lapse creation

Saturn 4: Does not have a camera

Power Loss Resume:

Saturn 4 Ultra: Supports power loss resume function

Saturn 4: Does not have this feature

Drip Tray:

Saturn 4 Ultra: Comes with a drip tray to prevent resin spillage

Saturn 4: Does not include a drip tray (though it's compatible)

Exposure Tester:

Saturn 4 Ultra: Has a built-in exposure tester function

Saturn 4: Does not have this feature

User Interface:

The two printers have different user interfaces, despite similar functionality

Firmware Updates:

Saturn 4 Ultra: Supports automatic firmware updates via Wi-Fi

Saturn 4: Requires manual firmware updates

Print Quality and Performance:

Both printers produce high-quality prints, thanks to their 12K mono screen displays. The reviewer demonstrated this by printing various miniatures, busts, and figurines. The prints showed crisp details and smooth surfaces, even on larger scale models.

The Saturn 4 Ultra, however, stands out for its significantly faster printing speeds due to its tilting vat mechanism. This was illustrated by a side-by-side comparison of a large print, where the Saturn 4 Ultra completed a much taller portion in the same time frame as the Saturn 4.

Reviewer's Observations:

The reviewer expressed high praise for both printers but had a few minor criticisms:

The lack of a handle on the flip-top lid, which might lead to resin contamination over time

The absence of a drip tray and built-in exposure tester on the Saturn 4

The need for manual firmware updates on the Saturn 4

Despite these small issues, the reviewer was impressed with the value offered by both printers, particularly the Saturn 4's $300 price point for its feature set.

Conclusion:

Both the ELEGOO Saturn 4 and Saturn 4 Ultra represent significant advancements in consumer-grade resin 3D printing. The Saturn 4 offers excellent value at $300, with auto-leveling and high-quality prints. For those willing to spend an extra $100, the Saturn 4 Ultra provides additional features like faster printing, Wi-Fi connectivity, and a built-in camera. Ultimately, both printers are strong contenders in the mid-size resin 3D printer market, with the choice between them depending on individual needs and budget.
