Before coming up with the Mars 2 Pro Mono, Elegoo released its Mars Two Mono 3D printer. Both of these machines are based on mSLA 3D printing technology. However, the Mars Two Mono has its own unique sets of features, different from its successor.

Providing high accuracy and very simple operation, the Mars Two Mono 3D is easier to handle. It has more than enough functionalities that couple together to turn your designs into amazing creations.

With the capability of supporting multiple languages, this machine suits an array of needs and is highly accessible to users from different geographical locations.

Hold on tight while we take you into the details of the Mars Two Mono 3D printer.


There is plenty to admire when it comes to the Mars Two Mono. And, here are some of the key features that stand out and make this printer a desirable choice for users with budget restrictions.

2K Monochrome LCD

The Mars Two Mono 3D printer comes with a masked LCD. The printer’s LCD is 6.08 inches long and has a 2K HD resolution. This helps to cure resins almost two times faster than other 3D printers. The resin curing is faster and lasts longer than that of normal RGS LCD 3D printers.

This leads to higher printing efficiency, more stable performances, and lesser maintenance costs. These three criteria offer great ease of use to beginners as well as experts.

The 2K HD LCD monochrome’s utilization ensures that you only take two seconds to cure a single layer. This also ensures a longer lifespan and stable performances. Hence, the operation is economically friendly while reducing the cost per print.

Multilingual Interface

Having a touch screen interface is something every 3D printer manufacturer is doing currently. What Elegoo has done is make the display available in more than one language! So users speaking different languages can operate the controls with ease.

The display’s backend consists of information in different languages, including Chinese, English, Japanese, Dutch, Korean, French, German, Russian, Italian, Spanish, Turkish, and Portuguese. This makes the printer suitable for worldwide users.

You can run the setup, change the settings, and start working in the language you prefer. You will therefore have no problem setting the designs or operating the prints. It offers you the trendiest features in a widely favored manner.

Replaceable Resin Tank and CNC Machined Aluminum

While printing parts with mSLA 3D printing, you are going to be dealing with liquid resins. Dealing with liquid is a bit of a hassle, especially if your surroundings are full of electrical components. However, Elegoo has taken good care of this scenario.

First of all, the Mars Two Mono comes with a green plastic tank manufactured from special engineering plastics made to protect the environment.

The best part is that you can replace the tank whenever you need it. Not only will this increase the overall life of the resin tank, but it will also assist you when doing continuous 3D printing.

The other feature equally noteworthy is how the Mars Two is made up of CNC machined aluminum. Therefore, it has a very solid build quality. It is a workhorse that gets work done under any scenario.

This also ensures that the printer stays stable during the entire 3D printing process. Hence, the users are able to create precise designs without worrying about the printer’s vibrations at faster speeds.

COB UV LED Light Source and Chitubox Slicer

The heart of an mSLA 3D printer is the light source. Because, it specifically, cures the resins.

The Mars Two has put the best-in-class COB light source into place, which provides excellent heat dissipation performance, high luminous maintenance rate, uniform light emission, and leaves no spots on the prints. Recently, it has gone through a fantastic upgrade to ensure that all your prints come out perfect.

For an ideal 3D printing process, you need a user-friendly slicer, and Chitubox is just that. Every Elegoo’s mSLA machine is compatible with this application.

Chitubox is updated with the latest eight times anti-aliasing function, which makes it possible to get smoother prints. It allows you to access some of the most advanced features to print even the most complex geometries easily.

The Elegoo Mars Two prints using mSLA 3D printing technology. It is also called the UV photocuring technique for 3D printing parts and functional prototypes of varying geometries. The objects made using this method have layer thickness ranging from 0.01 mm to 0.2 mm.

As far as print speed is concerned, you can start from as low as 30 millimeters per hour and extend up to 50 millimeters per hour.

The Z-axis accuracy offered by Mars Two is 0.00125 mm, whereas the XY resolution is around 0.05 mm. For better results and accurate curing, the printer uses a UV integrated light source with a wavelength of 405 nanometers.

When talking about the maximum build volume of the Mars Two, it is 129 mm * 80 mm * 150 mm. As we mentioned before, Mars Two has a touch screen interface that is multilingual, displaying information in twelve different languages. It is 3.5 inches long.

To transfer sliced files to your printer, you can use a USB cord. The printer weighs 6.2 kilograms. Power requirements of the Mars Two are between 100 to 240 Volts and  50/60 Hz.  Its dimensions are 20 cm * 20 cm * 41 cm.


Elegoo Mars Two is available for $199.

Print Type/Cost

mSLA 3D printing is a variant of SLA 3D printing technology. Hence, it uses a masked LCD to make sure the LED, which is the heart of any SLA 3D printer, functions more efficiently. As the name suggests, LCD is used to mask over the entire 3D printing process in which LED cures the liquid resin.

Point to point curing of different pixels occurs in SLA 3D printing, whereas point to point curing of various voxels occurs in mSLA 3D printing. The difference between pixels and voxels lies in the dimension. Therefore, SLA works in two dimensions, whereas the mSLA in three.

The cost of 3D printing a part generally depends on various factors. These include the geometry of the part, the type of resin, the cost of that resin, the support structure, and more. Usually, the cost per print for SLA models is higher than that of FDM parts.

Print Quality
