Ultimaker 2 - Overhang issues?

[dionisio 0]

Hi all.

My name is Dionisio and first of all is pleasure to be here and to work with an Ultimaker 2 product which arrived this week in our office.

Generally I am very very satisfied with the product. The prints are very detailed and I started already learning this new world.

I have only one issue, I am posting here some example images of simple things I tried to print these days.

The printed objects where created with these settings:

Layer Height 0.08

Shell Thickness 0.8

Print Speed 50mm/s

Travel speed 150, tried also 100 and 80. Same results.

Temperature 210 also tried 220, 230, 190... Always got same results.

Fan speed at maximum programmed to start after the 5mm layer.

Can't figure out what I am doing wrong.

I read about the overhang issue and the relation with the fan power. My fans are at the maximum. You confirm the max number is 255? (Tweak plugin).

That ear is a difficult part to get cleanly printed.

I would try to print slower. Lets say 25mm/s with the lowest possible temperature.

Thanks for answering!

And what about the travel speed, can impact on printing quality? I use 80 or 100 now...

Thanks!
