Acrylonitrile-styrene-acrylate (ASA) is a good substitute for ABS.
The material has been specially developed to be more resistant to weather conditions. ASA is an easy-to-print, strong and stiff filament for 3D printers. Chemicals and heat are not a problem for this material. When printing, ASA has fewer warping issues than ABS, but you should not over-cool the material.
