So I was printing with grey PLA using simplify 3D, .250 layer height, 4800 mm/min print speed (80mm/sec), 100% fan after 1st layer and noticed that as the print
got taller the distortion in the print got greater. I believe it is due to the printing speed and the effect of the weight of the object on the Y axis. The Y axis seems
to be the only axis that has "play" in it, i.e. you can grab the print bed and rotate it (VERY gently) as there is only one linear bearing. The weight of the print is
almost .5 kg and I am printing 2 at a time so ~1 kg total weight. Anyways, I have never had this distortion and was wondering if anyone else had issues with tall,
heavy objects at higher print speeds. I printed one at half the overall height and the same print speed with no distortion, but any input/advice is appreciated.
I'm thinking I should:
(A) reduce print speed (my least favorite option as it is already a 36 hour print at 80 mm/sec)
(B) adjust print speeds slower as the object gets taller (not sure if this is possible in simplify 3D) so 80 mm/sec for the 1st 2 cm, 60 mm/sec for the next 2 cm, etc.
(C) find out what the maximum object weight is until distortion starts
I have attached the 2 .stl files as well for reference
