When I print overhangs of an object, no matter large or small, the inner surface of the overhang part is always ugly, my guess is the material is slowly dropping because there is no support. How to avoid this and print a beautiful inner surface for overhang? problem pictures: http://pan.baidu.com/s/1kTqnS1p

Quite a lot to digest. Thank you all. I am going to tighten my belt as @gr5 suggested, and try Slic3r setting from @yellowshark (hopefully I can find a faster computer) and experiment different settings as @3Dmaker4U analyze. And will see what happens.

update from printing: Picture below. Same problem with different settings(30mm/s & 20 mm/s print time). Now I have no clue...any setting need to be adjust? http://pan.baidu.com/s/1c0GkrpI I have tried 2 different speeds for one print object, but one is bigger size. Here is the setting: Date 2014/9/27 2014/9/28 Name Bigger One Smaller One Layer height 0.1 0.1 Shell thickness 3.6 3.6 Fill Density 20 20 Print Speed 30 20 Temperature 190 190 Retraction 60 60 Scale 0.7/0.7/0.7 0.5/0.5/0.5 size 60.51/60.51/131.11 43.22/93.65/43.22 print time 11h 6h40 weight 61 22 Travel Speed 50 50 bottom layer speed 0 20 Infill speed 0 20 outer Shell speed 30 20 Inner shell speed 0 20

There is a big vertical line appear on cylinder object while printing the object vertically. Is anyone might know what could caused the problem and how to fix? Much appreciated. P.S. I wanted to post picture, but it told me that "You are not allowed to use that image extension on this community.", as such, I post link below: http://pan.baidu.com/s/1i3EDV3f http://pan.baidu.com/s/1fate2 http://pan.baidu.com/s/1nt7eibJ Many Thanks.
