Here are some results from a FL test a while back with carbon sheet. Carbon Sheet
You can see my results above for 1/32 milled glass fiber. The print went without issue and there appears to be a good amount of fiber in the part itself. Just have to do the testing still. This is where I got it, not sure about international supply sorry. Fibre Glast
I wouldn’t expect the same UTS increase as FredB since this is chop and not continuous strands. If you orient continuous strands in your load direction then as long as you get good bonding you will get the tensile strength of the fiber. My goal was to allow the fiber to give added strength in multiple directions by allowing random orientation. See Markforged
