Use it for
- Electronics enclosures, mechanical parts near heat, car interior pieces, and anything you want to sand, drill, or smooth with acetone vapor.
- It is tougher than PLA and survives heat that would soften PETG.
Watch out for
- Warping and layer cracks if the chamber is cold or there is a draft.
- Fumes while printing (styrene). Vent the enclosure to the outdoors, or print in a garage; a HEPA filter alone does not remove the gases.
- Sunlight makes it yellow and brittle over time, so use ASA outdoors.
Tips
- Use a brim, a very hot bed, and close the lid.
- Let the printer cool slowly before removing a large part.
