ゲルの複合材料を造形する3Dプリンターの開発

抄録

Various methods of 3D gel printers have been reported to produce on-demand flexible structures such as 3D cell scaffold materials and soft robots.3D gel printers can produce hollow structures of arbitrary shapes, which is difficult to achieve by mold forming.On the other hand, most 3D gel printers to date have been based on a single method, and it has been difficult to incorporate multiple gel materials with different mechanical properties into a single model.Therefore, we have developed a 3D gel printer (GelPiPer-multi) that employs two methods of modeling: a free surface method in which a laser beam is irradiated from the top surface of a tank filled with a solution, and a material extrusion method in which material is ejected from a nozzle.In this study, we report on the GelPiPer-multi and its modeling product, a composite gel structure.
