Product Description

Better Printing Experience

The upgraded USB air purifier comes with a plastic protective case that protects the built-in activated carbon filter and absorbs and filters resin odor during printing.

printing quality

9K Print Quality

The 7-inch 9K monochrome LCD with 8520x4320 resolution and 18x18 microns XY resolution allows you to print models with extremely fine details and sharp edges at a printing speed of up to 70mm/h, achieving superior quality and precision.

design, structure and build plate

Super Stable Structure

The Z-axis is driven by a linear guide rail that ensures stable and precise movement during printing, effectively reducing the layer texture and making the model surface smoother. With non-slip hexagon socket leveling screws, it's easy to level the build plate.

heat dissipation

Efficient Heat Dissipation

With a large cooling fan and heat-conducting copper tubes next to the COB light source for fast heat transfer, this ensures efficient heat dissipation performance and prolongs the service life of the printer.

voxeldance tango slicer

Voxeldance Tango Slicer

Mars 4 uses Voxeldance Tango Slicer, which offers three printing modes of static mode and dynamic mode (including smooth mode and high-speed mode) to improve printing efficiency and optimize your prints for quality and speed, or a balance of both.

Woeful quality
Without doubt the worst quality control I've ever seen. I've had the entire printer replaced, the power adaptor was faulty on delivery and had to be replaced, the vat screws have been replaced half a dozen times, I'm on LCD screen #3, had to replace a vat, and lost so much resin. This is in just 4 months. When it works it's good but it's not worked more often than it has!Elegoo have clearly employed the dumbest engineers for this printer. There are so many spectacularly stupid design flaws that it's astounding. The slightest resin spill and it goes straight down into the vat screws. The LCD screen then cures straight into the screw holes and you can no longer remove the vat. It's the worst design I've ever seen. It seems other Elegoo printers don't suffer as bad but the Mars 4 Max is absolute trash.

A few issues with the setup instructions, particularly with the software of the slicer. A brief search online found the missing instructions as many others had the same issue.

The printer itself is extremely good for a beginner like me, excellent results and a really good size build plate.

I've bought this as a replacement for my Mars 3 Pro, and it has not printed the test print once after 4 attempts.
I followed all the steps in the instructions, the printer wants to go beyond the glass protecting the lcd most of the time, and the 4 times it has printed, it has only printed a flat circle and not stuck to the build plate.
Elegoo customer support is not helpful.

Edit: Figured out the issue myself, after a good amount of googling. Instructions tell you to 0 the build plate to the leveling card, and this was the issue. Tried the old piece of paper to 0 the build plate and this worked. Has printed amazingly since

I liked the quality of the print, text is easy to read no layers that can be seen and it is noticeably quiet.
More accurate than filament.
What is Not to like; Resin is messy compared to the filament. May be just need practice
