Abstract

Although the development of 3D printing technology has enabled rapid prototyping of the 3D structures, the printing speed and price of current 3D printers are still poor compared to the 2D printing. Therefore, we propose a new method of 4D printing that changes into a three-dimensional structure by putting a two-dimensionally printed dry-erase marker into water. This was implemented by 'selective floating' using two different types of PVB-including inks, 'anchoring ink' and 'floating ink'. We used a pen plotter to print our inks accurately and showed that its 2D to 3D transformation in the water can be predicted using ABAQUS simulation. Also, we demonstrated that functional microparticles for hydrogel coating of the prints can be included in the ink, thereby realizing reinforcement of 3D structures, and maintaining 3D structures outside the water.
