How to install Cura on Ubuntu

Cura, or Ultimaker Cura is an popular open source 3D printing software. It is categorized as a slicer, or slicing software, used to convert the 3D model to the format which the 3D printer understands.

Suppose that you had an STL file that contains the modeled object, Ultimaker Cura converts the model into a series of thin layers and produces a G-code file containing instructions which a typical 3D printer can process.

Ultimaker Cura works with most of the popular 3D formats such as .STL, .OBJ, .X3D, .3MF (as well as image formats such as BMP, GIF, JPG and PNG). Thanks to its simple interface and easy to use workflow, beginners would have no problem getting started. The application also incorporated advanced features for seasoned professionals such as printing time estimation, third-party plugins upport, material changing, etc.

In this article, we will show you how to install Cura on Ubuntu, specifically the latest version – Ubuntu 20.04. The guide is applicable to older versions of Ubuntu and many other Linux distro based on Ubuntu, such as Linux Mint or Pop! OS.

Install Cura on Ubuntu using snap

Snap is the new way of installing software on Linux systems, introduced by Canonical, who owns Ubuntu. With snaps, you can install all of an app’s dependencies with a single command, and updates are automatic and resilient. Plus, apps run in their own isolated sandbox, thus minimizing security risks.

If your Ubuntu version is higher than 16.04, snap is already installed and ready to go, you don’t have to do anything else. For those who don’t want to check OS version, Ubuntu 16.04, 18.04 and 20.04 LTS has snap built-in. But in case you’re running legacy Ubuntu versions, as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd or running the following command.

sudo apt install snapd

If you are installing snap for the first time, it is advised to install the core package to make sure that all the basic features of snap works fine. In order to do that, run the following command in any terminal window :

sudo snap install core

You will see something like this

Now that snap is properly set up, all you need to do to install Cura is running the command below :

sudo snap install cura-slicer

Once the installation completes, you will see Cura show up on Ubuntu applications drawer.
