Which software application is utilized in the video for the purpose of slicing 3D models prior to printing?

• Tinkercad

• Ultimaker Cura

• Blender

• SolidWorks

In the context of 3D printing, what is the primary function of the "Preview" mode within Ultimaker Cura as demonstrated in the video?

• To visually inspect the completed 3D print.

• To determine specific layer heights for filament color changes.

• To modify the print speed and temperature settings.

• To assess the structural integrity and support requirements of the model.

Based on the demonstration, at which specific layer height is the first filament color change initiated to print the black features of the snowman model?

• Layer 1

• Layer 38

• Layer 53

• Layer 75

After configuring the filament change parameters within the "Post Processing Scripts" in Ultimaker Cura, what essential action must be performed to apply these changes to the 3D model's print path?

• Directly initiate the 3D printing process.

• Export the generated G-code to a storage device.

• Re-slice the model to incorporate the new script settings.

• Save the project file and restart the software.
