In this study, monofilament tensile strength of commercially available short carbon fiber reinforced thermoplastic (CFRTP) single wires ejected from a FDM (Fused Deposition Modeling) 3D printer nozzle was investigated together with their X-ray CT image analysis. Reconstructed 3D CT images of the present CFRTP single wires show that there were noticeable internal voids in the present samples of single wires. The CT slice image stacks were then used for cross-sectional area measurement of the wires. At least, from this preliminary and limited test results, any gauge length dependency in terms of monofilament tensile strength of the CFRTP wires for FDM-type 3D printing purpose was not observed in this study, which should be further discussed elsewhere.
