The ELEGOO Mars 4 Ultra 9K 3D Printer is a high-resolution MSLA resin 3D printer known for its speed and detail, making it particularly well-suited for miniatures and highly intricate models.

Here is a summary of its key features and specifications:

Key Features

 

  • Ultra-High Resolution: It features a 7-inch 9K Mono LCD with a resolution of $8520 \times 4320$ pixels. This translates to an excellent XY resolution of $18 \mu\text{m}$ (microns), which is why it’s highly praised for producing models with exceptional detail and crisp edges, perfect for things like miniatures.
  • High-Speed Printing: The printer can achieve speeds up to $150\text{ mm/h}$ when using the new ACF (Anti-Adhesion Coating Film) release liner and an ELEGOO rapid standard resin. This is significantly faster than previous models.
  • Connectivity and OS: It runs Linux with 4 GB of RAM, providing a fast, stable user interface. It supports High-Speed Wi-Fi transfer (6-10 Mbps) for both 2.4G and 5G networks, in addition to traditional USB printing.
  • Stable and User-Friendly Design:
    • It uses a 4-point leveling system that simplifies the process, requiring only one-time leveling.
    • The build plate features a laser-engraved surface to improve adhesion and significantly reduce print failures.
    • The Z-axis movement is stabilized by a linear guide rail structure with an accuracy of $0.02\text{ mm}$ for precise, stable movement.
    • It has an upgraded plug-in air purifier with an activated carbon filter to help mitigate resin odors.
    • The printer is controlled via a 4-inch HD IPS touchscreen.

Buying Advice

 

The Mars 4 Ultra 9K is considered an excellent choice for beginner to intermediate users who prioritize extreme detail in their prints, such as tabletop miniatures, jewelry molds, and small artistic models.

  • Pros: Outstanding print quality due to the $18\text{ \mu m}$ XY resolution, high printing speed, stable build, Wi-Fi connectivity, and a solid metal construction.
  • Considerations: While the build volume is modest, it’s typical for a standard-sized, high-detail resin printer in the Mars series. The ACF film, while enabling speed, is a consumable part. For those needing a significantly larger print area, a Saturn series printer would be a better fit, but for the highest detail at this size, the Mars 4 Ultra 9K is a top contender.
