Effect of extrusion FLOW RATE to the strength of 3D printed object
In this video I would like to see what is the effect of the extruding flow rate (or extrusion multiplier) to the strength of 3D printed object. The idea came when I did the review of digital microscope and I was analyzing a broken test specimen and I saw those gaps between the printing lines.
Material: 3D Active PLA, max walls (perimeters), 215°C/60°C (additional test with 2 perimeters and 20% infill). Printed on Prusa MK3S
