BASF's Ultrafuse PA datasheet calls for 80°C and at least 40 hours; Fiberlogy's PA12 page says 70°C and 4. Both are real specs for real nylon filament.

Prusament, Polymaker, Bambu Lab, eSun, Overture, Sunlu, Extrudr and Fiberlogy PETG side by side: tensile and heat figures, print settings and prices, with the test conditions that decide which numbers can share a column.
Bambu Lab says 51 MPa, eSun says 34.77 MPa, and both are printed PETG test bars. What to check on a datasheet before comparing two numbers: the standard, the bar, the print direction, the HDT load and the specimen conditions.
Tensile strength, elongation, heat deflection temperature, and print settings for five common FDM materials, pulled directly from manufacturer datasheets.
