The 3D printer was invented in 1980, 34 years ago. Today, there are signs of its spreading for personal use. I will describe the history of the technological innovation of the 3D printer and survey the future. I will discuss the various techniques of 3D printing, including the fused deposition modeling method, the stereo lithography method, the projection method, the selective laser sintering method, the ink-jet method, the ink-jet powder laminating method, and I will also describe the manufacturing process. The activity of the RepRap Community has become the driving force in the spread of low-priced personal 3D printers.
I will describe the present status of molecular modeling using a 3D printer. Teruo Nagaofs achievements in the field of 3D molecular-model making were splendid. I will report on the making of educational materials of molecular models that can be touched.
Key words: 3D printer, Making educational materials, 3D molecular model, RepRap community
