FUSED FILAMENT FABRICATION USING MULTI-SEGMENT FILAMENT

摘要

A thermoplastic filament adapted for use in a fused filament fabrication (FFF) printer which has a plurality of segments wherein each pair of adjacent segments is compositionally different and is arranged in a specific order. Also, a method for printing a three-dimensional (3D) article by printing such a filament in a fused filament fabrication (FFF) printer, wherein the fused filament fabrication (FFF) printer carries out a pattern of printing synchronized with the order of the segments in such a filament. Further, a method and device for fabricating such thermoplastic filaments.

主权项

1. An article comprising a thermoplastic filament adapted for a fused filament fabrication (FFF) printer, the filament comprising:
a plurality of segments, each of the segments comprising a thermoplastic polymer; each pair of adjacent segments having at least one different feature; wherein the segments are arranged in a specified order in the filament to provide a synchronized pattern of printing when the filament is printed with a fused filament fabrication (FFF) printer.
