Slic3r vs. CURA, 3D Printing Slicer Programs Comparison, and Contrast Guide

A critical part of your 3D printing experience is the slicer software. It’s the software where you get all your 3D printing settings and load up the design files. There is something called G-code, which essentially turns the design file to be readable by your 3D printer.

Among many different slicer programs, two famous names always have been in clash back and forth. It’s the classic battle between Slic3r vs. CURA. Here, I will go through a bit of comparison between these programs.

By the end of this, you will know which program suits your needs better. So, if you are confused about choosing one or the other, then this is the place to be. Let’s not waste any more time and jump right into it.

What Is Slic3r?

Now, this is an excellent slicer software for turning your STL design files into G-code. It’s open-source software for working on 3D model printing. There are lots of features and advantages you get from using the slic3r software for your 3D printing. Let’s go through them one by one.


The first thing to love about this Slic3r software is the broad compatibility this offers. You can use this software with a lot of different 3D printer brands out there. To name a few, Makerbot, Rostock, Ultimaker, Mach 3, TAZ, MakerGear, and so forth.

Also, it’s not just about the printers. You also get good compatibility for reading files. The software can easily read STL, AMF, and OBJ files and provide you with the G-code. It also gives out SVG files which are so easy to edit using any coder.

Aside from that, it’s also compatible with most operating systems. Whether you are using Linux, Windows, or macOS, you don’t need to worry about that. Since it’s open-source software, you download it and start using it.

About CURA

Now, let’s dive deep into another renowned slicer software CURA. This is one of the top software when it comes to slicer software for 3D printing. It essentially comes from the brand Ultimaker. Many professionals use this software for their 3D printing purposes, making it a lot more reliable than a slicer software. Let’s quickly check out the features and see why professionals rely on this one.


Here’s the thing with CURA, you will never have to worry about compatibility. Even though it comes from Ultimaker, you can use this software for almost any 3D printer brand. It even comes with profiles for different 3D printer brands out there.

Coming to the aspect of file compatibility, well, it outweighs almost any other software there. You can work with STL, X3D, OBJ, 3MF files along with JPG, BMP, GIF, and even PNG files. There is no limitation to working with these files on CURA whatsoever.

And as you can already guess, it’s compatible with all operating systems as well. It’s open-source software, after all.

The Cura software is super simple to use, even for a beginner out there. The thing that makes it easy to use is the premade profiles options. Suppose you don’t know anything about the slicer settings. You simply choose a profile based on your printer. That’s enough to get some 3D prints without causing any issue at all.

Need to work on advanced stuff? Well, hop into the custom options and get complete control over your slicer software to edit those advanced settings.

Added plugins

A great advantage you get with CURA software is the integration of the plugin. You can add plugins to the software to make your 3D printing experience more fulfilling and accessible. Some plugins make the whole printing process more accessible than you can even imagine.

Filled with features

Well, it’s free software that comes loaded with features and functions. You get everything you would need in slicer software for accessible and high-quality 3D prints. There is simply nothing missing from the software.

It gives a lot of tweaking options like density, padding, layers before you start printing. Forgot to change some G-codes? Well, you can vary your g-code while it’s printing with the CURA software. Everything works perfectly with this software.

Overall, it’s an excellent slicer software that you can use for your 3D printing purposes. As a beginner, you should stick to the premade profiles. But as you start to get the hang of it, you can move on with the advanced stuff that unlocks the software’s true potential. If you want to know more about CURA, I have got an in-depth look into that as well; you can check it out.
