Investigating Annealing as Fix for Poor CF Adhesion in 3D Prints

After recently publishing a few videos covering research into the poor adhesion between chopped carbon fiber (CCF) and the thermoplastic filaments as used with FDM 3D printing, some of the feedback received by [I built a thing] included the idea that the missing step to make CCF additives work was post-print annealing. Naturally this claim had to be investigated , both through the resulting physical characteristics as well as on a microscopic level in the same scanning electron microscope (SEM)
