Seventh Grade, 3D Printing Science Projects (4 results)
3D printing, also called additive manufacturing, is a rapidly changing technology that allows for the quick creation of small batches of products. Traditional manufacturing usually involves cutting products out of raw materials or pouring raw materials into molds. In contrast, 3D printing creates a product by adding layer after layer of material using computer-controlled robotics. 3D printing processes are being used to create a growing number of products, from food to custom prosthetics. With the help of different types of 3D printers, additive manufacturing can be used for enormous objects like a house or rocket as well as tiny things the size of a pencil tip.

Try the annual Engineering Challenge from Science Buddies! Open to all students worldwide, a new challenge and prizes are announced every January. Explore the current challenge as well as ones from past years!
The "impossible arrow" is an amazing optical illusion: an arrow that always seems to point to the right, even when you rotate it 180°. If you place the arrow in front of a mirror, however, its reflection points to the left! How does this illusion work? Can you design your own "impossible" shapes? Try this project and find out!

In this engineering challenge, you will build a car powered by nothing but a rubber band. The farther the car goes, and the fewer materials you use to build it, the higher your score. Enter your score in the 2024 Science Buddies Engineering Challenge for a chance to win prizes! Teachers, lesson plan versions of this challenge are also available.
Drones come in all shapes and sizes. In this engineering project you will design and 3D-print your own frame for a miniature drone.
Science Buddies has several fun robotics projects, like the
Art Bot: Build a Wobbly Robot That Creates Art
and
Grasping with Straws: Make a Robot Hand Using Drinking Straws,
where you use arts and crafts materials to make part of a robot. Have you ever wanted to design a more-advanced, sturdier, or fancier looking robot? Then computer-aided design (CAD) and 3D printing might be for you; both are simpler than you think! The directions on this page will give you an introduction to these…
The Science Buddies project Design Your Own 3D Printed Optical Illusion shows you how to make your own 3D printed "anomalous mirror symmetry" illusions (Figure 1). The illusions are based on the work of Dr. Kokichi Sugihara. You can read his original paper about the illusions in the Bibliography.
Figure 1. Two versions of the "impossible arrow" shape that appears to point to the right while its reflection in the mirror appears to point to the left. Which…
