Today we make a little science experiment to test whether printing slower actually makes your prints stronger. The results might suprise you!

The test was done with Fil-A-Gehr red ABS
(https://en.gehr.de/products-and-applications/fil-a-gehr-3d-fimants/fil-a-gehr-abs.html)

I used the following print settings:

Bed Temp: 110°
Nozzle Temp: 250°
Overall Print speed: 25-50-75-100mm/s
Nozzle diameter: 0.6mm
layer height: 0.25mm
Wall thickness: 1.2mm (2 extrusion widths)
Fan Speed: 35%
Linear Advance (Marlin V1.1.8): K=150

You can see the final plot results here:
