Let's compare PLA vs ASA 3D printed bolts and screw nuts. ASA (Acrylic Styrene Acrylonitrile) is a technical material that is considered a successor to ABS. ASA is UV resistant and has higher heat deflection temperatures, but it is harder for printing, it requires higher temperatures, brim and some enclosure. This test is not only about ASA or PLA 3D printed bolts, but more about understanding properties of these materials.

Materials I used in this test:
Gembird PLA printed on Prusa MK3s
Prusament ASA printed on Ender3 V2
