    "A higher heat-deflection temperature is not an outdoor-years claim. The catalog has no UV column, and these sheets are not quoted here as one.",
    "writes 80f and says direct sunlight can warp PLA. That figure is the comment. It is not a PLA glass-transition number from a sheet on this page.",
    "PolyLite ASA's bed is 75–95 °C (167–203 °F) and its nozzle starts at 230 °C (446 °F). A PETG profile does not become an ASA profile because the part is going outside."

  "pros": [
    "The heat numbers keep the load, 0.45 MPa and 1.8 MPa, on the same brand.",
