Consumer Fused Filament Fabrication (FFF) desktop 3D printers are used for prototyping, spare parts and even smallscale production, but produce parts with lower tensile strength than traditional manufacturing methods. High tensile continuous fibers increase filament composite strength, but poor fiber adhesion and pull-out are common weaknesses. The few commercially available continuous fiber reinforced (CFR) filaments are costly and only compatible with their manufacturer’s machines.
This work describes the development of a method and a prototype apparatus to produce standardized CFR filament, addressing the weaknesses of CFR thermoplastics while maintaining their compatibility with consumer 3D printers, and thereby achieving mechanical properties required for costeffective ... view more»
