All blasters are made entirely from ABS and/or ASA filament. Both of these are much less brittle than PLA, making them far superior for functional parts. ASA has an even higher UV rating than ABS but with less of a variety of colors. PETG is another filament with high strength properties but very difficult to achieve the quality of prints I strive for. You shouldn't have to worry about taking special care with these, they can be dropped, knocked off a table, etc., because accidents happen!
