How should I test filament samples? I have just ordered some filament samples (each sample is 10m x 1.75mm). How should I test the samples, given that there is only 10 metres of each to play with? Just printing a benchy will use about 4 metres. I would probably want to print a benchy, so that leaves 6 metres to play with. I am mostly interested in producing functional (not decorative) pieces. I do not have a heated bed.
Select an STL that exhibits characteristics you want to test (bridging, resistance to various pressures) and print it with each material. Preferably, run the same exact gcode, only changing temperatures, so that you get an apples-to-apples comparison.
