Thanks. Ordered 10 rolls of the PETG-CF. I've been using the Flashforge PETG-CF with great success, but at this price it's worth the gamble.

Fiber infused filaments leave bits of fiber in your skin. They are also bad for your lungs if you sand them, so wear a respirator.

Where are you getting this from? I've looked at prints under a scanning electron microscope and all of the CF bits were mostly, if not all, subsurface and parallel to the extrusion direction. maybe if you sand or break the print, but as printed I could barely see them on the surface with Tinmorry PETG-CF.

How does PETG-CF print? I've had a good deal of spaghetti failures on my X1C with normal PETG. So much so that I've started printing with ABS when I need strength parts (eg pegboard hooks) and it's printed so much easier.

Weird. PETG prints best on my X1C.
It became my go to material. Prints even better than PLA.

I clean my build plate with all purpose cleaner (Mr. Meyer's) every few prints.

Guys, do research on CF before buying it, in short, whatever extra durability you get from CF, it is not worth the health risk. It is both harmful in smell and touch (both raw and finished product). CF was designed to have a varnish or another layer of non-CF before being safe to handle.

I've actually had better results printing PETG-CF than many other types of PETG. The type I have is from a brand I believe called Eryone. It has been excellent and makes really cool matte looking prints with little fuss at all.

With my printer I did upgrade to hardened nozzle and gear set per manufacturer recommendation.

SEM at 530x of Tinmorry PETG-CF scored and snapped perpendicular to the extrusion direction to enhance fiber pullout, as sawing would melt the PETG and cutting would bend/wipe everything over. Note the very very few surface and basically no perpendicular CF rods on the untouched surface on the right; little to no danger from handling after printing. If there were CF rods all over the surface to be picked up, poked into skin, or inhaled, there would be more divots or trenches on the surface where they cooled coming out of the nozzle.
The left is close to what a cross-section would be showing the CF fill amount and some of the rods pulled out. All the holes once had CF fibers but were rinsed out or still stuck to the other side of the piece not imaged. *note the great layer adhesion between the middle and bottom layers resisting the layer separation forces!

Research done and you are quite mistaken. You do know that carbon fiber is essentially pure carbon after undergoing a 2000-3000 C process for the sole purpose of "burning" everything else off, right? There is essentially nothing left on pure carbon/carbon fiber that would be harmful to smell during 270 C printing. Below is SEM imagery showing that PETG-CF is safe to handle as there is very very little CF on the surface and basically no CF rods perpendicular to the extrusion.

I'm not going to say whether carbon fiber is or is not safe in the context of 3D printing, but I think some caution is warranted given its known hazards in other uses/environments. Your sample size of 1 is super narrow, and until we have studies available I don't think you should be declaring it safe. I can list many chemically inert materials besides carbon fiber that you wouldn't want in your respiratory system, some of which have strict inhalation regulations. Asbestos is uniquely hazardous because of the small particle/needle size (and instigates cancer by physical rather than chemical means), but various other dusts (rock/mineral/glass/composite) can cause severe issues as well (like silicosis). Personally, I suggest treating CF (and glass-filled) filaments with some basic precautions, especially when sanding (as you would when installing fiberglass insulation).

Most have probably noticed, but sold at the same price on Amazon now: https://www.amazon.com/ELEGOO-Fil...0F37YCK6K/

Does anyone run Elegoo filament in an X1C with AMS? I just ordered one and wondering if the spools are the right size to feed properly

Just be sure to print spool rings/rims, if you buy their filament with cardboard spools. There are versions that will only take ~12 grams.
They work well in my AMS 2 Pro + X1C. I'm a fan of Elegoo's filament - particularly the rPETG & Galaxy PLA.

Looking forward to working with the GF versions. Love the finish and the stiffness and strength increases are substantial.
