<p>Select an STL that exhibits characteristics you want to test (bridging, resistance to various pressures) and print it with each material. Preferably, run the <strong>same exact gcode</strong>, only changing temperatures, so that you get an apples-to-apples comparison.</p>

<p>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.</p>

Test them for *what*? In my opinion, your question isn't specific enough. You're just asking us to come up with a list of things you could to do test a filament. It would be much better if you asked how you can test something specific (like strength, or hardness, etc...).

There are some simple steps you can write your G-code for that.

1. Filament should have accuracy of diameter 1.75 mm
2. Write G-code into file for next test case and run on machine

   1. For continue extrusion 100mm at different feed rate **F50** `F100 F150 F200` up to the machine's maximum feedrate G-code for that

      ```
      G91
      G92 E0
      G1 E100 F50

      ```
   2. You have prime and suck parameter for your machine so test it. For example, prime and suck both are 4 mm and repeat last two line to continue testing

      ```
      G91
      G92 E0
      G90
      G1 E5 F100
      G1 E1 F100
      G1 E5 F100
      G1 E1 F100

      ```
   3. This test for continue extrude and wait for 2 sec and then extrude again, repeat following G-code again and again continue

      ```
      G90
      G92 E0
      G1 E10 F100
      G4 P2

      ```
   4. Test prime suck with delay

      ```
      G92 E0
      G90
      G1 E5 F100
      G4 P2
      G1 E1 F100
      G4 P2
      G1 E5 F100
      G4 P2 
      G1 E1 F100     

      ```
   5. Final is print

In all of the above tests filament should not getting jammed and, for new material, temperature also may be a problem - so first set temperature for a new material.

Before starting test cases, clean the nozzle.
