    Description

    There is a detailed post where I tested several materials with both a pull test and a bend test. Here I am posting the STL files that I used for this test. See details here:

    umforum.ultimaker.com/index.php?/topic/7575-strength-of-different-filaments/

    BEND MEASUREMENTS (zoom in on diagram picture - the center picture with the checkerboard pattern under the part - you have to click the image until you see the red/blue marks) should be made with the red line in diagram over the edge of a table or counter (use sharp edge table) and the blue arrow indicates where to measure vertical deflection.  This is the point on the straight part - use another test piece to measure where in space the part was before it deflected and measure from bottom of unloaded part at blue arrow straight down to wherever it intersects with the bent part.

    Settings in Cura were:

    20% infill, .8mm shell, .6mm top/bottom thickness (for bend test)

    For pull test infill was 0%, top/bottom disabled, .8mm wall/shell thickness.

    Other settings should be irrelevant to the strength as long as layer bonding is good (temp, speed, brim, fan, support, etc).
