Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary joining principle?Geometric complementarity of mating surfaces
2. What is the distinction from force-fit?Relies on shape, not interference or friction, for retention
3. How do form-fit connections stay strong?The shapes fit exactly, keeping the parts in the right position and letting them handle pushes, pulls, and twists.
4. Why do builders use form-fit instead of screws?It makes the building look cleaner, saves time, and can be easier to take apart or fix later.

Geometric Complementarity: Shapes designed to fit together precisely, like puzzle pieces.
Interference Fit: A connection where parts are forced together due to slight size differences.
Additive Manufacturing: Building objects layer by layer, often referred to as 3D printing.
