An apparatus, system, and method for a low tension application spooler and or coiler system that positively drives the material into the coil and or reel so that the tension is minimum during the winding process.

The present invention relates to a feeding control system of a 3D printer and a feeding control method thereof. The feeding control system, used with a filament, comprises a first feeding apparatus, a second feeding apparatus, and a feeding sensor. The first feeding apparatus comprises an outlet, a fixed wheel set, a movable wheel set, and a controller. The fixed wheel set and the movable wheel set hold and deliver the filament to the outlet. The controller is disposed corresponding to the movable wheel set. The second feeding apparatus is installed in the 3D printer. The feeding sensor is disposed corresponding to the second feeding apparatus and used to sense entrance of the filament to generate a release signal. After receiving the release signal, the controller drives the movable wheel set to move away from the fixed wheel set to release the filament.

A filament feeder for use in an additive manufacturing system, comprising a main feeder body having mounted thereon a first biasing roller and a driven first gripper roller arranged at an adjustable first roller distance from each other allowing a filament material to be received between the first biasing roller and the first gripper roller. The filament feeder further comprises a second biasing roller and a driven second gripper roller arranged at an adjustable second roller distance from each other for receiving the filament material. A biasing assembly is provided in resilient engagement with the first and second biasing rollers and configured to bias the first and second biasing rollers toward the first and second gripper rollers, respectively, during an additive manufacturing process.
