What bites people
This is the outdoor structural filament — ASA's UV resistance plus glass fill's dimensional stability. If a part lives in the sun AND has to hold a tolerance, this is the answer.
Warps far less than plain ASA, but the enclosure requirement does not go away.
Hardened steel nozzle required.
Safety
Same styrene-family emissions as ABS and ASA. Ventilate to outside air or filter properly.
Abrasive — hardened nozzle required.
Do not sand without a mask. Glass fibre dust is a respiratory irritant.
