The Dremel 3D40 build platform provides the removable building surface for your Dremel 3D40 Idea Builder printer. Its smooth and level surface allows consistent builds and ensures print quality. The build platform can be used to replace the original platform that came with your 3D40 printer or used as a second, alternate platform to quicken print jobs. Build sheets and tape that protect the build plate are sold separately. Build size: 8" x 12".
