By the end of this lesson, students will be able to:

1. Identify key file formats used in 3D printing.
   Answer: The most common format is .STL (Stereolithography).

2. Explain what a slicer software does.
   Answer: A slicer converts 3D models into layer-by-layer instructions for printers.

3. Set up print parameters like layer height, infill, and supports.
   Answer: Students will adjust slicer settings for accuracy, strength, and quality.

4. Understand how 3D printers construct physical objects.
   Answer: Printers use melted filament to build from bottom to top, layer by layer.
