Extrusion Width Testing of 3D Printed Specimens

I want to share a little experiment I did and see if I can tap the wisdom of the crowd here to better understand the results.

I ran mechanical tests on 3D printed specimens with various extrusion widths to determine the effect that it would have on printed part strength.

The results were normalized to compensate for the higher strength of heavier parts and enable fair comparison of all specimens tested. This was done by dividing the measured ultimate strength over the mass of the part
