This assignment is about characterizing the 3D printer we have in our lab. The 3D printer is PRUSA i3 MK3 as shown in the image below.
Test parts
The test files are available in the class archive. We downloaded them and sliced them then printed them.
Results
Surface finish
We used layer height of 0.2 mm which resulted in a pretty smooth surface finish.
Overhang
Overhang taller than 8 mm were deformed which shows that the maximum overhang for our printer is 8 mm.
Bridging
Bridging result were very good for all lengthes and without any deformation.
angle
Angles less than 30 resulted in a deformed output which tells us that with angles lower than 30 we should use support.
wall thickness
We used 0.4 mm nozzle so we see that the minimum wall thickness is 0.4 mm.
Clearance
Clearnece of 0.2 is sufficient for free movement without jiggling.
Dimensions
Outer dimension is over with 0.08 mm meanwhile inner dimension is exact.
