Elegoo has built a name in the 3D printing industry by delivering top-tier machines that creators trust. Their printers have gained popularity for their dependable performance and user-friendly features. The company continues to refine its technology and develop new innovative products. Resin 3D printing has revolutionized how creators produce high-quality models. Unlike filament printers, resin printers use light to cure liquid resin, resulting in sharper models with smoother finishes. This method has become a favorite among hobbyists, designers, and engineers who want to produce visually striking models like miniatures, prototypes, and decorative pieces. In this review, we’ll explore the Elegoo Mars 4 Max, one of the company’s latest resin 3D printers. We’ll break down its features, printing capabilities, and overall performance, helping you see how it measures up in the ever-evolving field of 3D printing.

Design and Build Quality

The Elegoo Mars 4 Max comes with a sturdy metal frame that supports stable and consistent printing. Its compact size fits well into different workspaces while still offering a generous build area of 195.84 x 122.4 x 150 mm³, making it capable of handling various 3D printing projects with ease. At the center of the printer is its 9.1-inch 6K mono LCD screen, delivering sharp resolution at 5760×3600 pixels. A 9H hardness tempered glass protector shields the screen from scratches and everyday wear, helping extend its usability. The sandblasted build plate securely grips printed models, reducing the chance of failed prints. The 20mm thicker Z-axis linear guide rail keeps vertical movement steady, cutting down vibrations that could affect print quality.

Key Features and Specifications

The Mars 4 Max brings advanced features designed for efficient and high-quality resin 3D printing. Its 9.1-inch 6K monochrome LCD delivers a resolution of 5760×3600 pixels, producing sharp models with an impressive XY resolution of 34 microns. The COB+ refractive light source ensures even light distribution across the build area. The printer uses a dual cooling fan system for efficient heat dissipation, extending its lifespan by reducing internal heat buildup. Its 20mm thicker Z-axis linear guide rail minimizes vibrations, ensuring smoother vertical movement during prints. The sandblasted build plate enhances print adhesion, reducing failed prints. Elegoo’s self-developed GOO slice format is compatible with popular slicing software like CHITUBOX and Lychee Slicer, offering flexible printing options. Voxeldance Tango software supports multiple printing modes, including static mode and dynamic modes for speed and efficiency. An optional USB-connected air purifier reduces resin odors for a better printing environment.

Comparisons

Mars 4 Max vs. Mars 3 Pro

The Mars 3 Pro has been a favorite among resin 3D printing makers for its dependable print performance. However, the Mars 4 Max takes things to a higher level with better resolution, faster speeds, and advanced printing. Features aimed at improving both output and ease of use.

• Resolution and Display: The Mars 3 Pro features a 6.6-inch 4K monochrome LCD with a resolution of 4098×2560, delivering solid print results. In contrast, the Mars 4 Max comes equipped with a larger 9.1-inch 6K mono LCD at 5760×3600 resolution. This gives sharper prints at 34-micron XY resolution for more detailed models.
• Printing Speed: While the Mars 3 Pro reaches speeds of up to 50mm/h, the Mars 4 Max achieves 70mm/h thanks to its advanced COB+ refractive light source and optimized printing technology, enabling faster prints without compromising quality.
• Smart Features: The Mars 3 Pro supports USB offline printing. The Mars 4 Max expands its capabilities with Voxeldance Tango slicing software and compatibility with popular third-party slicers like CHITUBOX and Lychee Slicer. The Mars 4 Max also includes a USB air purifier connection for better odor control. This makes it more suitable for long printing sessions.

Mars 4 Max vs. Saturn 2

The Saturn 2 is a larger resin 3D printer known for its big build volume and advanced features. However, the Mars 4 Max is about delivering detailed prints at higher speeds while having a more compact form.

• Resolution and Display: The Saturn 2 features a 10-inch 8K mono LCD with a resolution of 7680×4320, producing highly accurate prints. The Mars 4 Max, while smaller at 9.1 inches, still delivers sharp prints with its 6K mono LCD at 5760×3600 resolution and 34-micron XY resolution, making it a strong competitor in terms of print quality.
• Printing Speed: The Saturn 2 supports speeds of up to 90mm/h, making it ideal for larger prints. Meanwhile, the Mars 4 Max pushes speeds up to 70mm/h, optimized by its COB+ refractive light source and dynamic printing modes from its Voxeldance Tango software, making it faster for smaller but highly detailed projects.
• Smart Features: The Saturn 2 features both USB and Ethernet connectivity, catering to larger production environments. On the other hand, the Mars 4 Max keeps things simple with USB offline printing, along with enhanced slicing compatibility and multiple printing modes for more efficient, personalized prints. Its dual cooling fan system and air purifier compatibility ensure a cleaner, longer-lasting printing setup.

Real World Applications

The Elegoo Mars 4 Max is designed for different resin 3D printing projects. Its combination of high-resolution printing, fast speeds, and user-friendly features make it a useful tool across several industries.

• Miniatures and Collectibles: The Mars 4 Max’s 9.1-inch 6K mono LCD with 34-micron XY resolution makes it perfect for creatng highly detailed miniatures, figures, and collectibles. Game designers, tabletop gamers, and model makers can create finely detailed models with lifelike features.
• Product Prototyping: With a build volume of 195.84 x 122.4 x 150 mm³, the Mars 4 Max is well-suited for product prototyping. Engineers and designers can create accurate prototypes for product testing and design validation before mass production.
• Dental and Medical Models: The high print resolution and fast speeds of the Mars 4 Max are ideal for producing dental models, orthodontic devices, and anatomical models. Its ability to print with bio-compatible resins also supports medical applications such as custom implants and surgical guides.
• Art and Jewelry Design: Artists and jewelers can benefit from the Mars 4 Max’s exceptional print accuracy. It can produce intricate jewelry designs, custom molds, and art sculptures, helping creators bring their concepts to life with fine textures and clean surfaces.
