Specifications

Highlights

Let’s take a look at the Mars 3 Pro’s prominent updates compared to the Mars 3 model.

Improved light source

One of the most important changes in the Pro version is the upgraded light source. It consists of a free-form surface COB lens incorporating 36 highly integrated UV LED lights and a newly added Fresnel lens delivering an even beam of 405nm wavelength. Enhanced light uniformity results in smoother surface finish and overall impressive print quality making for a truly Pro approach.

Extra air purifier

Another helpful innovation borrowed from the Saturn series is a USB-powered air purifier with an active carbon filter that effectively absorbs and eliminates unpleasant fumes and odors that come with resin 3D printing. The device operates directly inside the printer and is indispensable for a fresh working environment. Luckily, it is supplied with the Mars 3 Pro by default.

Upgraded ventilation

Apart from the aforementioned improvements, the Mars 3 Pro is equipped with an upgraded ventilation mechanism. It includes dual copper heat tubes and a powerful cooling fan providing faster heat transfer and better cooling efficiency. In the long run, this significantly extends the service life of the printer and the quality of its outputs.

Enhanced screen protection

What makes the Pro version even more user-friendly and reliable, is a replaceable anti-scratch tempered glass with 9H hardness that basically serves as a built-in screen protector. On top of the improved light transmittance resulting in a higher level of detail for the printed models, it leads to the simplified cleaning and replacement procedures, which is another step forward for the Mars series.

Thoughtful package

To make your user experience with the Mars 3 Pro even more comfortable, ELEGOO supplies the printer with 2 extra FEP 2.0 films for free. This will come in handy for a higher printing success rate since this release liner offers more adhesion and less deformation in comparison with its counterparts.

Other features

In terms of the screen resolution and build volume, the Mars 3 Pro is not different from the standard model. It boasts a 6.6" 4K monochrome LCD screen with 4098 x 2560 px resolution and build area of 143 x 89.6 x 175 mm ready for a single large model as well as time-saving batch printing. To maximize stability and boost performance of the printer, ELEGOO have also engineered it with non-slip hexagon socket leveling screws and sandblasted oxide surface build plate. Taking into account all these bright features, it is easy to see what makes the model really Pro.
