3D Printer

Several 3D models made using a 3D printer are shown in this page. 3D structures are also visualized by webGL; click each structure. webGL is not supported for Internet Explorer. Please use another browser. For Safari, you need setting. See here how to set up. The STL files (standard format for 3D printer) are available. I cannot guarantee that they work at all the 3D printers, and there are no official support. Nevertheless if you have a problem with the files or suggestion to improve them, please let me know yoshinaga@wpi-aimr.tohoku.ac.jp.

There are several free STL viewer softwares ( The product version is required for modification of a STL file.). You could download from the following pages.
