Slicing STL files can be a daunting task, but luckily there are many software programs out there that can make the process much easier. Ultimaker Cura is one such program that is specifically designed for slicing STL files. 

But, do you know why a lot of 3D printing enthusiasts choose to slice STL files in Cura? And how to Slice STL Files in Cura?

How to slice STL files in Cura

Let’s get started!

How to slice STL files in Cura

Slice STL files mean converting STL files to G-Code files to let the 3D printer understand. Ultimaker Cura is one of the best STL to G-code converters. To be continued, we'll show you how to slice STL files in Cura so that you can get started printing your 3D models right away.

Step 1: Download and install Cura. You can find the latest version of Cura here. Once you have Cura installed, launch the program and add your printer, in my situation, added Creality Ender-3 Pro. And click on the "Next" button to continue.

Step 2: Now, in the top left corner, go to File > Open File(s) > Select Model File.

Upload your file on Cura

Step 3: After uploading the file, you will want to remain within the recommended settings as provided within Cura. Or you can customize your print settings. When you're happy with your slicing settings, click on the "Slice" button.

Step 4: When the slicing process is complete, you can preview and save the slice file to the desk. Now you're ready to start printing!


Pros and cons of slicing an STL file in Cura?

Utilizing Cura to slice an STL file is a great tool for 3D printing enthusiasts to leverage in preparing their models for printing.


  • By slicing the 3D model into many layers, Cura produces a crisp and clean output with far greater resolution than would be possible by 3D printing by itself. 
  • Furthermore, users can also modify the settings in relation to material composition, layer height, and more which are essential for improving print quality and precision. 
  • Another great advantage of using Cura is that it allows users to view their sliced model before exporting the G-code required for producing the actual 3D object through software like Repetier Host or Slic3r Prusa Edition. This not only saves time and money but also promotes user satisfaction since they can ensure that their model remains true to its intended design.


Despite its many benefits, Cura has some notable drawbacks. 

  • It can be difficult to learn and understand, with a steep learning curve for new users. 
  • Additionally, the 3D prints it produces may also not always be known to match up perfectly with the design file or even the first layer of filament down in certain cases. 
  • Furthermore, Cura is unable to print multiple objects at once with one click of a button, meaning long waits and additional steps that have to be taken in order to print multiple objects. 
  • Lastly, it is limited in terms so STL files only and cannot unpack zip archives containing the desired 3D model files.

The best alternative way to slice a 3D model for printing

Now you learned more details about Cura for slicing STL files, including the pros and cons. If you are looking for the best alternative to slice STL files, it is not controversial to say that Creality Print is your best choice.
