Abstract – Conventional 3D design methods design only the surface of 3D objects and conventional 3D printing methods only slice and print 3D objects horizontally. We in Dasyn.com develop new 3D design methods that enable designing real 3D objects including the internal structures and textures, and develop new 3D printing methods that enable printing patterns with nonhorizontal directions. The “real 3D design method” makes transparent objects and objects with holes much more realistic, and the non-horizontal 3D printing method enables naturallydirected objects such as 3D calligraphies. We also develops a naturally randomized or fluctuated 3D printing method. We seek partners who will develop applications of these methods.
