PLA settings in Grabcad

Hello everyone,

My question is how can I modify the PLA settings in grabcad for a stratasys f370?

the "basic" mode is not good enough since the faces are too loose and not close knitted.(top and Bottom)
I refuse to believe it is the best it can do since it prints wonderfully with ABS.

Any suggestions?
( I have even tried with insight still no luck)
