Cilllia – 3D Printed Micro-Pillar Structures for Surface Texture, Actuation and Sensing
Published on July 8, 2016
Looking into the Nature, hair has numerous functions such as to provide warmth, adhesion, locomotion, sensing, a sense of touch, as well as it’s well known aesthetic qualities.
This work presents a method for 3D printing hair-like structures on both flat and curved surfaces. It allows a user to design and fabricate hair geometries that are smaller than 100 micron.
The ability to fabricate customized hair structures enables us to create super fine surface texture; mechanical adhesion property; new passive actuators and touch sensors on a 3D printed artifact. They built a software platform to let users quickly define the hair angle, thickness, density, and height. The ability to fabricate customized hair-like structures not only expands the library of 3D-printable shapes, but also enables us to design passive actuators and swipe sensors.
They also present several applications that show how the 3Dprinted hair can be used for designing everyday interactive objects.
