If they have heated chambers for their printers, ASA/ABS shouldn’t be too much of an issue. I print ASA on the regular without a heated chamber (but with a heat soaked enclosure), and I can print fairly large parts without too much warping (200x160x100 worst case scenario). I’m fairly confident another 10-15° (up from the 35-40° my enclosure is now) and I would eliminate the warping completely. They would just need a bit of XYZ compensation to manage the shrinking, but that seems completely reasonable for a commercial endeavour. It seems much more reasonable than using PLA or PETG, neither of which would survive a summer afternoon sun beating down on them.
