Corkfill is a specialty filament which looks, feels, and behaves just like cork material. You can use Corkfill to make light-weight wood objects or traditional cork items such as dart boards and wine corks. Corkfill is a combination of PLA and Cork wood fibers. Colorfabb's Corkfill is PLA based, so you can print this filament on any printer than can handle PLA filament.
