Outline of Final Research Achievements

In this study, we have developed a 3D block printing technique using multiple ceramic blocks to construct 3D functional devices. Silicone mold made by micro stereolithography was used for making small ceramics blocks. To make the blocks, dense slurry containing ceramic microparticles is inserted into the mold, and then the blocks are released from the mold after drying the slurry. As the first demonstration of the 3D block printing, multiple bio-ceramic blocks were produced using the 3D molding technique. To assemble the blocks, we have developed an algorithm for stably assembling blocks by calculating the center of gravity of the assembled blocks. According to the algorithm, the blocks were automatically assembled by the combination of a multi degree-of-freedom robotic manipulator and image recognition system.
