Yep, in case you didn't know, it's now possible to 3D print rubber objects. Which is why we've released TREDDY -- free, open-source software that generates ready-to-print CAD files for custom rubber stamps, using any text or vector logo art. But TREDDY does a whole lot more than generate rubber stamps. It can also be used to generate stamplike messages on paint rollers and ink brayers; on wheels for skateboards and toys; and on any flat or cylindrical surface. TREDDY even has a special option to export 3D models of shoe soles with messages in their tread. No matter the application, TREDDY generates "watertight" meshes in the .STL file format, immediately ready for 3D printing. TREDDY is a project of the Free Art and Technology (F.A.T.) Lab, 2013 Developed at the Frank-Ratchye STUDIO for Creative Inquiry at CMU by Golan Levin, Randy Sarafan, and Jordan C. Parsons The TREDDY rubber-stamp generator is free, open-source software, released under the GNU General Public License (GPLv3): fffff.at/wheels TREDDY was created with Processing, an open-source arts-engineering toolkit, using the additional libraries: controlP5, Geomerative, PeasyCam, and toxicLibs. All rubber prints fabricated with the Objet Connex 500 multi-material 3D printer. Video: Riley Harmon Music: "Proud Mary" cover by 8BitRenditions (Orig.
