3D Printing Videos (2 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.

Is this shape a circle, a square, or both? The 3D printed "ambiguous cylinder" illusion by Prof. Kokichi Sugihara seems impossible. Learn how it works and how to make your own at Science Buddies: https://www.sciencebuddies.org/stem-activities/ambiguous-cylinder-illusion. Short version of the video: https://youtube.com/shorts/fYJolHtgWuw Also check out the Impossible Arrow illusion: https://youtu.be/D54yMlIMN80 Science Buddies also hosts a library of instructions for over 1,500 other hands-on…
Make your own amazing 3D printed optical illusions based on the work of Professor Kokichi Sugihara, including the "impossible arrow" and other shapes! These illusions exhibit "anomalous mirror symmetry" where their reflections appear flipped left to right in a mirror. Instructions and working example code in both MATLAB and Python are available on the Science Buddies website:…
