Catapult Design Project

Catapults were destructive siege engines in medieval times. In this project, you design and fabricate a model catapult to learn the basics of CAD and 3D printing. These projects include documents, videos, and step-by-step instructions.

• Grade: 9-12
• Length: 4-6 hours
• Difficulty: Moderate
• Software: SOLIDWORKS xDesign (though SOLIDWORKS 3D CAD can also be used)
• Learning Objectives: Understand different types of catapults. Design with constraints by applying design intent to the project. Explore and understand manufacturing principles. Understand the basics of 3D printing.
• Materials Needed: Filament (approximately 70g), 1 package of #2 size rubber bands, 1 package of (30) 7/8" diameter foam balls
