The humid summer weather didn’t stop a thousand 3D printing fanatics from gathering at a county fairground in Amish Country for the 13th Annual Midwest RepRap Festival in Goshen, IN. Hobbyists showed off hand-built mods, businesses showcased their new innovations, pallets of filament were for sale, and in the back room, builders bashed 3D-printed robots.
MRRF is a one-of-a-kind event: part high-tech swap meet, part networking, and all kinds of fun. The event started 13 years ago when a local 3D printing manufacturer decided to host a gathering to celebrate 3D printing in its hometown. The festival is named after the open-source RepRap movement that liberated 3D printing from the corporate additive manufacturing industry. MRRF has successfully spun off sister festivals in Maryland, Colorado, England, and Japan. Each festival is independently hosted, but the purpose is the same: to celebrate homegrown 3D printing technology.
Anyone who’s been 3D printing for a while can appreciate Cody Bean’s open source Printventory STL file organizer. Bean, also known as “TechJeeper,” said he created the program because he would often forget where he had saved files and grew tired of having to redownload them. The community-supported software can organize files by name or designer and let you tag them how you like.
