Simple Elegoo Mars UV 3D Printer Review – Worth Buying or Not?

Elegoo Mars UV 3D Printer Review - 3DPrinterly

The resin 3D printing field has been definitely growing in traction, one of the popular candidates being the Elegoo Mars UV 3D printer. It was first released in 2017 and since then, has been a top choice for users who are moving from FDM printing to resin printing.

I think the first thing we can admire is the pricing of this machine, being well under the $1,000 mark and not requiring you to dig deep into your pockets to add it to your collection.

It doesn’t matter whether you’re a beginner or a specialist, the Elegoo Mars is going to do you justice in terms of easy operation, high-end print quality and serious performance, even though it’s a relatively small machine.

If you are looking for a budget resin 3D printer, this is an amazing choice.

The Elegoo Mars UV Photocuring LCD 3D printer is an incredible printer at the cost. It looks pleasant, performs well, and does not occupy a lot of room on a workbench.

Simplicity is what was in mind with this user interface. Not only is operation easy, but the whole printing process is pretty streamlined and has a very short learning curve.

Compared to an FDM 3D printer, this resin printer is going to easily out-do them quality-wise.

Quick Slicing Software

When talking about 3D printers, speed always matters. Elegoo Mars UV comes with the latest version of ChiTuBox Slicing Software which gives you extraordinary user experience.

ChiTuBox takes only 1 minute to slice 30MB .STL model files while the open-sourced slicing software would take up to 10minutes.

ChiTuBox allows you to hollow out your model before slicing which could save your resin dramatically during photo-curing process.

Off-line Printing

You do not need to connect it to the computer while printing, you can easily get your prints while inserting the USB.

Downsides of Elegoo Mars UV

One of the common complaints with the Elegoo Mars is the location of the USB connection. It’s in an area which isn’t too easily accessible depending on where you set the 3D printer up.

Noise is something that comes into play, with the fan of this 3D printer being pretty loud even though it is an enclosed machine.

The removable cover which blocks UV light is quite poorly designed, maybe due to the low price point. In order to get proper access to the machine and resin tank, you may need to remove the cover.

Every so often, after extended lengths of printing, it is discovered that the firmware of the printer sometimes stumbles over when stacking up another print.

You need to pay close attention to the orientation of each model, because a bad orientation can result in an unsuccessful print. It can take a little bit of practice, but once you understand this, it’s pretty smooth sailing.

It’s advised to orientate your models so that large flat areas are printed on a diagonal, meaning it doesn’t print in a single layer. This decreases chances of these large layers sticking to the vat. It avoids pieces of your model sticking to the film on the bottom of the resin vat.

There were reports of other failures with this 3D printer, but with a solid firmware update most of these issues have been corrected, so if you see bad reviews it is most likely down to those previous issues.

Unfortunately you don’t get a nice sample of resin for you to try out so you’ll need to purchase your own from the beginning.
