Elegoo Mars 4 Review

Elegoo has carved a niche in the 3D printing and open-source electronics industry since its founding in 2015 by Chris Hong in Shenzhen, China. The name “Elegoo” from “ELE” signifies open-source electronics, and “GOO” refers to the astronomical number googol, symbolizing the endless possibilities enabled by their products. Elegoo’s mission is clear: empower makers, students, and professionals to create with tools that integrate technology and structure. Resin 3D printers, a key product in Elegoo’s lineup, have gained significant attention for their ability to produce high-quality, detailed prints. These 3D printers are better at achieving smoother finishes and sharper details compared to traditional filament-based printers. By using liquid resin cured with UV light, they deliver precision and consistency, ideal for crafting intricate models, prototypes, and artistic creations. In this Elegoo Mars 4 review, we’ll take a look at its advanced features, practical performance, and real world applications.

The Mars 4 showcases a practical design built for precision and convenience. Its compact structure houses a 7-inch 9K monochrome LCD screen. This delivers exceptional detail in every print. The laser-carved build plate ensures solid adhesion during printing while making it easy to remove finished models, saving time and effort. The raised step on the mid-plate prevents resin from flowing into the printer’s internal components. This detail makes this model more durable and minimizes the risk of damage. The printer also includes non-slip hexagon socket leveling screws, making it straightforward to level the build plate accurately. The Z-axis is supported by a linear guide rail, which provides stable and smooth movement during printing. This significantly reduces layer lines, resulting in finer, smoother model surfaces. Elegoo has combined these elements to create a machine that’s durable, efficient, and user-friendly.

Mars 4 takes resin 3D printing to the next level with advanced features and improved design upgrades. Its 7-inch 9K monochrome LCD provides a resolution of 8520×4320. This delivers incredibly detailed and sharp prints. The COB light source, with 36 evenly distributed LEDs, ensures consistent UV light coverage, resulting in smooth and precise prints. A laser-carved build plate enhances adhesion, while the efficient heat dissipation system, featuring a large fan and copper tubes, prolongs the printer’s service life. The Mars 4 also uses the Voxeldance Tango Slicer, which includes three dynamic printing modes to balance speed and quality. Additionally, the open-sourced GOO slice file supports third-party slicing software for flexibility.

Mars 4 vs. Mars 3 Pro

Elegoo Mars 3 Pro

The Mars 4 and Mars 3 Pro are two advanced models in Elegoo’s Mars series. Both have impressive features, but the Mars 4 introduces upgrades in resolution, build volume, and printing efficiency.

  • Resolution: The Mars 4 has a 7-inch 9K monochrome LCD with an 8520×4320 resolution. This achieves 18-micron XY precision. In contrast, the Mars 3 Pro features a 6.6-inch 4K monochrome LCD with a 4098×2560 resolution, resulting in 35-micron XY precision. This means the Mars 4 can produce finer details and sharper edges.
  • Build Volume: The Mars 4 offers a build volume of 153.36 x 77.76 x 175 mm³, while the Mars 3 Pro provides 143 x 89.6 x 175 mm³. This gives the Mars 4 a slightly larger printing area.
  • Cooling System: The Mars 4 is equipped with a large cooling fan and heat-conducting copper tubes. This ensures efficient heat dissipation and prolongs the printer’s service life. The Mars 3 Pro also features cooling mechanisms, but the Mars 4’s system offers improved efficiency.

Mars 4 vs. Mars 2 Pro

Elegoo Mars 2 Pro

Comparing the Mars 4 to the Mars 2 Pro highlights just how much resin 3D printing has evolved. With significant advancements in resolution, build volume, and speed, the Mars 4 takes what the Mars 2 Pro does well and pushes it to new heights.

  • Resolution: The Mars 4’s 9K LCD provides a significant upgrade over the Mars 2 Pro’s 2K monochrome LCD. This has a resolution of 2560×1620 and an XY precision of 50 microns. This advancement allows the Mars 4 to produce much finer details.
  • Build Volume: The Mars 4 offers a larger build volume compared to the Mars 2 Pro’s 129 x 80 x 160 mm³, so you can create bigger models.
  • Printing Speed: The Mars 4 achieves printing speeds of up to 70mm/h. Whereas the Mars 2 Pro operates at approximately 30-50mm/h, making the Mars 4 more efficient for larger projects.
  • Light Source: While the Mars 2 Pro employs a COB LED light source, the Mars 4’s enhanced COB light source design provides more uniform UV light distribution, resulting in better print accuracy.

The Mars 4 is designed for creators who want their projects to have exceptional detail and accuracy . Its 9K monochrome LCD and 18-micron XY resolution make it a top choice for tasks requiring intricate designs and smooth finishes. Here are some of its practical applications:
