The Mars 3 Pro is characterized just as much by its similarities to the original Mars 3 as it is by its differences. After all, the two printers are largely the same when it comes to specs and raw ability. We know both the original Mars and the Mars 2 Pro apply the cob light source, which is a highly efficient integrated area light technology that attaches the LED chip directly to the substrate. Whereas, there are some disparities in the way light sources are utilized between the two. When Mars reflects the light onto the LCD screen using the mirror of the reflector, the light reaches the screen in a messy way, causing the sharpness of edge areas to be reduced and the details to be less than perfect. Meanwhile, the area of scattered light is so large that partial lights can not reach the screen. I noticed that the print volume is significantly larger than its predecessor directly from the dimensions of the resin vat. It is much deeper and can hold more resin, so you do not have to refill during printing. And to be able to test the print quality, I first printed a resin test matrix to calibrate the exposure time. After that, I printed two busts with a lot of details to push the limits of this 3D printer. At 143 x 89.6 x 175 mm, the Elegoo Mars 3 offers a significantly larger printing capacity than its predecessors and other monochrome 4K re-printers.

Powerful COB Light Source] Upgraded free-form surface COB lens consists of 36 highly integrated UV LED lights, paired with Fresnel lens to deliver an even beam of 405nm wavelength with 92% light uniformity for a more smooth surface finish and incredible printing quality. User-Friendly Touch Screen】Navigate easily with the 4-inch HD IPS touch screen with a resolution of 800*480 pixels and support for 12 languages, making operation a breeze for users of all skill levels. I myself use the Eco Resin from Anycubic* with which this almost always happens if I do not use PTFE lubricant*. With the PTFE lubricant, you lubricate the FEP film, which makes the adhesion to this extremely difficult.

Customer Reviews

While it is significantly more costly than any other Elegoo 3D printer, rest assured it will be well worth it. Already when printing this test matrix I noticed that the accuracies are really excellent. I could see the text exactly and all edges and corners were precisely executed. After that, I had high hopes for my busts! Dwarf Bust Caution: The .LCD file will be automatically updated after restarting the machine in the shutdown state. Please do not update repeatedly to avoid being prompted "Same Firmware already exists!"

Efficient Heat Dissipation】Double fan cooling system design, one for air inlet and the other for air outlet, has faster air circulation and higher heat dissipation efficiency, which extends the service life of 3D printers. The Mars series is well-known for creating high resolution and highly detailed prints, which is part of the reason it’s so popular amongst entry-level and experienced hobbyists alike. Specifically, the Mars 3 has a 4K resolution and an XY resolution of 35 microns. With a 4K resolution and a simultaneous moderate edge smoothing (antialiasing) by the slicer, you get objects that show hardly any traces of the typical steps of 3D printers. The objects resemble injection molded parts! 4K vs. 2KTo do this, you only need one drop, which you spread evenly over the film. Make sure that no liquid residue of the lubricant remains on the film. Even if the film is no longer 100% transparent, the results will not be negatively affected. Textured Printing Plate Between health concerns and a general distaste for bad smells, the fumes that resin printers generate are always a hot-button issue. Unfortunately, the Mars 3 doesn’t come with any type of filter.

Fast and Silent Printing] Neptune2s 3D printer equipped with a 32-bit motherboard and SMT32F chip, with a memory up to 1M FLASH makes the system run smoother and faster; The Silent stepper driver ensures that the motherboard has silent printing and accurate voltage output to ensure silent printing. Smart and Convenient】3.5'' inch color touch screen equipped with the latest ELEGOO CHITUBOX 5.5 system makes it very easy for off-line printing. The build platform with steel ball balancing structure inside allows you to start printing within 5 minutes after assembly. Z-axis Dual Lead Screw】The dual synchronized lead screws and dual-motor drive make the Z-axis movement more stable and smooth, avoid printing deviation driven by a single Z-axis lead screw motor, and improve printing accuracy and stability. With an STM 32-bit motherboard, the X/Y/Z/E axes are all driven by silent drivers to effectively reduce the printing noise to below 50 dB.
