  • Simple mode is best for beginners and offers simple settings.
  • Advanced and expert mode is ideal for professional users. It also offers an advanced setting.

After one setup is completed, you can start slicing for the first model.


Step 2: Importing and Manipulating 3D Models

2.1 Importing a 3D Model

PrusaSlicer free download supports a variety of file formats such as STLOBJ3MF, and AMF. These file formats are efficient for importing the models.

  • Click on the desired file and import it.
  • You can directly drag and drop the 3D model file in the Prusa windows.

2.2 Manipulating the Model

After importing 3D models, follow the below steps.

  • Move: Click the Move tool (shortcut: M), then click drag and drop models to print it on the desired position.
  • Scale: Select the Scale tool (shortcut: S) which allows you to resize the model.
  • Rotate: Use the Rotate tool (shortcut: R) that enables you to adjust the model’s orientation.

The software offers you an Auto Arrange feature that arranges different objects on the print bed.


Step 3: Basic Print Settings

After completing the above two setups, then you must do the basic print setting to improve the print quality.

3.1 Layer Height

  • Layer height enables you to determine and adjust the thickness of each layer. The smaller layer height is (e.g., 0.1 mm) and the larger layer height is (e.g., 0.3 mm).

3.2 Infill Density and Pattern

  • Infill contains internal structures that play a role in strength and stability. The software offers you several infill patterns like gridgyroid,  honeycomb and many more. If you need a stronger print, then a higher density is best for you.

3.3 Perimeters and Shells

  • Perimeters enable you to determine the outer walls of your model. Normally,  2-3 perimeters are used.

3.4 Supports

  • If the model contains complex features, then add the support. The software directly generates support structures to cover every angle. You can also add or remove the support anytime according to your needs.

Step 4: Slicing the Model

After the basic setting, then you need to slice the models by following the below steps.

4.1 Slice the Model

  • Click the Slice Now the software generates a G-code file which helps you with quality printing.

4.2 Save the G-code

Now, you need to save the G-code. The software allows you to transfer the file via SD card or USB.


Step 5: Starting the Print

After saving the G-code, you can easily start printing.

5.1 Prepare the Printer

  • Load the filament: You need to add a collection of filament to improve the print quality.
  • Level the bed: To get the quality results of printing, level the bed for smooth performance.

5.2 Start the Print

  • Insert the SD card or connect via USB and start the printing process.
  • Monitor the first few layers, and check if it is working well or not.

Step 6: Post-Processing and Finishing Touches

After the printing completion, then you need to follow the below steps.

6.1 Removing the Print
