As far as any danger handling this, I've heard several people say it's completely fine in printed form, in general, but you just definitely want to be more safe and careful if you are sanding it at all.

In my own experience and under a SEM, PETG-CF all prints parallel to the surface (aligned with print direction) and little/none of the fibers stick out. They are also usually 80 and 140 um long. In the end, CF is much safer for your lungs than glass/SiO2, since CF is pretty benign and your body can break down pure carbon. For small particle size damage, you're extremely unlikely going to be able to break the very strong carbon fibers down into small enough (<10um) lengths for that hazard to manifest.

Good info! I'm still wary enough to just avoid it myself... but good info for others who may decide to sand the material.
