Hiroya Tanaka and Hitomi Kuboki from Keio University SFC will speak at the 4D Printing & Meta Materials Conference, on April 22, during the 3D Printing Event at Brightlands Chemelot Campus in The Netherlands.
We have designed 4D-Printed Shoes, Cars, Facades and others with several special materials.

One way to 4D print is through the use of Shape Memory Polymers (SMP). these are a type of polymer which react to an external stimulus (e.g. temperature) and subsequently change their shape in a programmed manner. Previous 4D printing research has focused on different material properties (chemistry) or geometric shape (size, thickness etc.) to control its morphing behaviour.

Metamaterials have attracted large scientiﬁc interest as promising candidates to break some fundamental bound on materials properties and to realize some dreaming devices such as the invisibility cloaks or the perfect ﬂat lenses based on negative refraction.
However, the bounds appeared to be more fundamental and the ﬁeld has extended to some coupled physical phenomena where one physics acts as the driving force. They are called stimuli-responsive metamaterials and have been demonstrated in many combinations like thermoelastic, magneto-optics, piezo-electric etc. In this paper, we show the possibility of printing the basic elements of a 3 axis microrobot using single-step lithography.
