Filaments for outdoor and high-temperature use

If the print is going to sit on a balcony, in a car, in an unheated garage or next to something that gets hot, PLA is out — its declared temperature resistance is 60 °C. This category holds the four materials with the highest declared values in the range.

An important caveat: these are values declared by the manufacturer in its own FDM data table, not the results of testing to any standard — Porima publishes no test reports. Nor do we hold any data on how these materials stand up to sunlight, so we make no claim about it.

The price paid for that resistance is much the same across all four: a high bed temperature (80–120 °C) and 6–12 hours of drying before printing. ABS additionally warps badly and smells strongly, while PA requires drying for 8–12 h at 65–80 °C — without that it is not worth opening the packet.

The data comes from Porima's official FDM technical data table. Full listing of 25 materials: print parameters.
