It is easier to print than ABS but it is still not a beginner filament like PLA or PETG are - your Mini can print it (the E3D hotend and your heatbed can handle it) but you will need it in a properly vented enclosure, both to help maintain the temperature it needs (high) as well as filter out the smell - although ASA isn't nearly as bad as some I still do want to use the least toxic chemical possible. But manufacturers usually add additives to their filament for different reasons which basically means each spool is basically unique in profile. ABS has been found to release 3 to 30 times more nanoparticles than PLA. Regarding emissions, the following recent report, Emissions of Ultrafine Particles and Volatile Organic Compounds from Commercially Available Desktop Three-Dimensional Printers with Multiple Filaments, indicates that PLA is a pretty low emitter (1/20th of nylon) and most of what it out-gasses is Lactide which is low on the harm scale. 2.
