Two-Color Filament Kick 3D Printed Optical Illusion A Groove Up

A new video from [Make Anything] Shows a nice combo that has a real visual effect: blurred shapes look different depending on the angle at which they are viewed, combined with an unusual filament that greatly enhances the effect. As you can see in the picture above that shows such an object in front of the mirror, the results are quite interesting.

Japanese mathematician and artist [Kokichi Sugihara] The math behind such an object is out, of which its obscure cylinder illusion is probably the most well-known. That inspired [Make Anything] To create his own strange object, which he happily displays. But he added one more twist.

This filament is divided into two colors along the middle.

What is the natural complement of an object that looks different depending on the way it is viewed? A filament whose color depends on which side it is seen on, of course! The filament in question is the Matterhackers Quantum Dual-Color PLA, and this unusual filament splits into two different colors along the middle, creating a printed object whose exact color depends entirely on the viewing angle and the geometry of the object.

When viewed with a mirror, the resulting objects look particularly attractive, because as the object rotates and changes, so does the color. You can see it effectively in the video below (embedded after the page break) which shows several different approaches to the concept, so check it out to see them.

3D printing has certainly opened a new door when it comes to brain-bending optical effects, such as this hypnotic Moiré pattern, and perhaps even dual-color filaments can enhance them.
