Abstract
The present disclosure relates to a process, system and apparatus for multi-material additive manufacturing process comprising: extruding an extrudable material through a nozzle capable of moving along one or more axis and concurrently extruding one or more filaments, wherein the filament is embedded in, on or about the extrudable material from the nozzle.
Claims4
A method for segmenting and feeding a fiber comprising:
- providing a continuous fiber;
- providing a capillary having a lumen;
- advancing the fiber through the lumen in a downstream direction;
- locally damaging the fiber in a region upstream of the capillary;
- advancing the fiber downstream until the damaged region is inside the capillary;
- clamping the fiber inside the capillary at a location downstream of the damaged region so the fiber cannot move;
- applying tension to the fiber upstream of the capillary to break the fiber in the damaged region and yield a downstream wire segment;
- releasing the downstream wire segment within the capillary so the downstream wire segment can be advanced;
- advancing the downstream wire segment by pushing the downstream wire segment with the fiber upstream of the segment,
- wherein a fiber segment of the desired length is delivered by the capillary.
