MakerBot Industries was founded in 2009 by Bre Pettis and Adam Mayer to create affordable and accessible 3D printers. They released their first 3D printer and sold them all at the SXSW festival that year. Since then, over 2500 MakerBot 3D printers have been sold and are used by a highly motivated community of users who not only make products but share their designs on Thingiverse and help improve and update the 3D printers. MakerBot's goal was to make 3D printing truly open and accessible to users.
