Abstract
A filament feeding device () for use in 3D-printing comprising a first feeding wheel () configured to rotate with a first rotational shaft () and a second feeding wheel () configured to rotate with a second rotational shaft (). The first and second feeding wheels () are separated by a separation distance so as to allow feeding of a filament material received between said first and second filament wheels (). The filament feeding device further comprises an adjuster element () movable between a first distinct position () setting said separation distance to a first predetermined distance, and into a second distinct position () setting said separation distance to a second predetermined distance, and wherein said second predetermined separation distance is larger than said first predetermined separation distance. Further, a 3D-printer comprising such a filament feeding device is herein disclosed.
