Perhaps the first 4D resin in the world. TIKO-M 4D resin can be easily moulded into a desired shape after printing under heat (50°C). When it cools, it retains the desired shape. When heated again to 50°C, the material remembers and resumes its printed shape.
Our tests on TIKO-M 4D resin
At first, we designed and printed two simple Springs, cleaned and post-cured them. Thickness was about 2mm. The PicoFab small minimum printing volume (10-20ml) is perfect to test expensive or exotic resin, like this one.
The spring, mounted on a support, was connected to a small weight and heated to about 40°C. Then the weight has been removed. On the video, you can see that by heating again to 40-50°C, the springs goes back to the original shape. It works!
Playing with the next idea. I designed a simple 3D Printed robot, with a magnet put inside. The idea is to use the magnet to move the robot around, and use the memory-shape properties to “squish” the robot when it has to move into narrow passages.
