How to Use Ultimaker Cura to Prepare Designs for 3D Printing
If you have been into 3D printing for a while, chances are high that you might have heard of or come across Cura, as it’s one of the most popular 3D slicing software available. If you’ve never used it before, we will guide you from the download and installation to exploring its features and tools, such as 3D slicing to generating G code to send to your 3D Printer, installing plugins and how to update and back up your settings and profile.
Downloading Cura and installing it
Click here to go to the Ultimaker website Download the software for Windows, Mac or Linux. You will be able to select your 3D printer after you launch the program. The window will launch and you can choose if you’re using an Ultimaker or not.
Since I do not use one, I choose Printers that do not UltimakerYou will then be presented with a new window where you will have the option to choose whether or not you want to add the 3D printer. In my case, I didn’t have a machine on the network, so I chose non-networked and a list of 3D printer launched, as shown below.
Click on the machine you want to select. AddYou will see something similar to this window.
Then you can add profiles and adjust the settings to suit your machine. If you don’t know the proper settings, select the Import The top-right corner of the interface contains an option.
After that, you can proceed to the interface.
You will see an intuitive interface when you first launch the software. On top of that, you’ll find a menu bar with options to create a project, to open files, to view recent projects and to export files once you are done working on them. There are also settings for the 3D printer, extruder, and software configuration.
Below the menu bar is an icon of a file folder. When you click on this icon, you will be given the option to import files. The software supports most 3D formats, such as STL and OBJ. It also supports DAE, 3MF, G-code, DAE 3MF, and 3MF. You will find the most important features in the middle of the interface. Prepare yourself for the arrival of your guests.This is the default setting. As the name suggests, it’s the option to select when preparing your file for 3D printing. The PREVIEW option, besides Prepare yourself for the arrival of your guests.The third option is to preview your file in real time and see how it will look when 3D printed. The third option is MONITORThis allows you to remotely monitor your 3D Printer. This option will only work if your 3D Printer is connected to your computer.
You can customize the settings of your print by using tabs on the right-hand sidebar. These include material, infill and quality.
Having looked at the overview, let’s now look at how to import and modify your files in the software.
Cura Imports and adjusts 3D models
Click here to go to File > Open File(s) Locate your file to import into the software.
You will find tools in the middle left section of the interface after you import the model.
You can also move the design by specifying the X, Y, and Z values. You can move the model by specifying X,Y and Z values.
You will find the scale tool below the move option. This allows you to scale the design. Like the move tool you can also use the points that appear on the design in order to scale it according to your needs. You can also scale the model by specifying the X,Y and Z settings. By adjusting the values, I have scaled down the model below.
Next, you can rotate your design around the XYZ-axis. To change the angle, you can move the circular circles around the model. Selecting the icons to the left will also allow you to align the model’s face with the build plate or make it lay flat.
Mirroring the object along the X-Y-Z axis is possible by selecting the option beneath rotation. This will create a copy of the model in a mirror. The mirrored version has the same dimensions and shapes as the original model, but is flipped on the selected axis. By selecting the desired transformation or orientation, you can restore it to its default state. Editorial section.
The next feature to be discussed is the Per Model Settings This allows you to apply specific models to settings. You can also launch additional settings by clicking the button. Select your settings.
On a model-by-model basis, you can adjust various settings such as layer height, print speeds, temperatures, infill densities, support settings and more.
Cura 3D Slicing
Click on the slice button to create your design. Slice Option in the bottom-right section of the interface.
Before you can do this, you will need to apply the appropriate settings for your design, material and 3D printer. The settings are located in the upper left corner of the interface. The above design, for example, needs support due to the overhangs. I will just activate Support Set the desired settings.
You can also choose what type of support you want and where to put it. You will also need to adjust the following settings according to the 3D model you are using, your printer and material:
- Infill density and pattern as well as shell settingsThe density of the infill determines the thickness and size of the interior structure. Infill patterns determine how interior 3D prints are filled. Shell thickness settings, on the other hand determine how many solid layers are printed around the outside surface of your object.
- Layer heightAs its name implies, this setting is used to determine the thickness of every layer that will be 3D printed.
- Walls and wall decorThis setting will determine the number or shells and walls that surround your design. Its strength and look are affected by this setting.
- MaterialsClicking on it will reveal an option for adjusting the temperature of your printing plate and building plate. This can be set based on what material you’re using.
- Speed upThis setting controls the speed of the printer’s print nozzle.
- Travel settingsYou will then see the option to enable the retraction. This tells the filament that it should retract from the nozzle when moving from one non-printed component to another.
- CoolingIt is useful for controlling the rate of cooling the filament by the extruder as it prints to ensure all the layers are sufficiently cooled.
- Build plate adhesionYou can select from a variety of adhesion options, such as a skirt or brim.
After applying the settings click Slice Go to the PREVIEW Click on the section to see how your design will look.
The Preview slider on the left sidebar allows you to see your model layer by layer. You can examine potential issues and see how the print will proceed. When you’re satisfied with the result, click on the button to save the G code. Save Disk Option on the bottom right of the workspace.
Understanding Cura Plugins
Cura allows you to add extensions or plugins to customize and enhance its functionality. These plugins provide additional features that extend beyond the capabilities of the slicer. They allow you to perform certain actions, modify G code, or add new print settings. You can manage or add them by clicking on the Extensions Section on the menu bar.
Click the Download button to download your plugins. Markets You will find a list of plug-ins in the section at the top right.
Click on the Install Plugin button to begin. InstallCura will download it and automatically add it to your slicer. If you don’t need to scroll to locate your preferred plugin, you can use the search bar to locate it. You can also download material profiles that are optimized for your 3D Printer by clicking on the Materials Option section
Click the Settings icon in the top right corner to view or deactivate installed plugins.
There are other plugins that you can use. Post processing The downloadable version of the software is available in the Extensions > Post Processing > Modify G-Code section. These plugins enable you to modify G-codes after slicing. You can, for example, pause a print at a certain layer height, insert custom G-code, or perform additional actions before or after the print.
Click on it to see the various scripts that are available. You can also add your own by clicking Add a script.
Update Cura and Backup Settings
Update and backup Cura settings to ensure that you have the most recent features, bug fixes and compatibility for your 3D printer. Visit the site to check for any new updates. Extension > Update Checker > Check for updates. You will be notified if there are any updates. If not, a notification will appear on the button section in the workspace.
You will update in case of an update. Click on Extensions > Cura Backups > Manage backups Back up your settings
Clicking on this option will open a new window, asking you to sign in to Cura. This will then redirect you to the default browser where you can sign up or sign in if you are not already registered with Ultimaker.
You should be able to navigate the Cura software and workflow, and use it to optimize your 3D print process.
