Beschreibung
Zusammenfassung:	A device and a method for transporting a filament and a device for printing a three-dimensional object in layers by fused filament fabrication are provided. The device for transporting a filament includes: a drive device (1) configured to generate a torque, a first force transmitting element (2A) and a second force transmitting element (2B), a first coupling element (8A) and a second coupling element (8B), at least an adjustment element (3), wherein the first coupling element (8A) is coupled between the at least one drive device (1) and the first force transmitting element (2A) to transmit the torque to the first force transmitting element (2A), wherein the first force transmitting element (2A) is rotatably supported on the first coupling element (8A), wherein the second coupling element (8B) is coupled between the at least one drive device (1) and the second force transmitting element (2B) to transmit the torque to the second force transmitting element (2B), wherein the second force transmitting element (2B) is rotatably supported on the second coupling element (8B), wherein the first coupling element (8A) and the second coupling element (8B) are positioned relative to each other that the filament (4) can be moved by and between the first coupling element (8A) and the second coupling element (8B), wherein the adjustment element (3) is configured to adjust the position between the first coupling element (8A) and the second coupling element (8B) to adjust a force (F) applied to the filament (4) when moved between the first coupling element (8A) and the second coupling element (8B).
