Printed with Printrbot Simple Metal, Settings: 195C, 40mm/s, layerhight 0.1mm, density 15%, retraction speed 40mm/s, retraction distance 4mm. i notice its main problems are overhangs and bridging.
I have considered that maybe it is my filament that i am using so i have ordered some colorfabb pla/pha filament and when that arives i will be doing some tests on that. Currently i am useing Filament from Seacans.com
It doesn’t look too bad, honestly. Slightly better than what I printed on my old wooden Printrbot.

Hey, how’s it going. I’m assuming your using the stock heater so something I would look into is again assuming your printing in pla maybe a lower temp. Some are kinda choosy on what temp they like. I’ve never used that particular brand of filliment so I can’t say for sure, I’m a sucker for hatchbox filliment. Never a problem with it.

Overhangs could be easier to achieve with 0.2mm layer height, in any case the fan cooling is the priority here, maximum speed + good fan duct. For bridging I personnally slow the print speed down to 20/30mm.sec. Along with the maximum fan speed. Might be useful to upgrade it a littlle.

That looks like good filament to me. I’m no expert though. Is there a retraction at those points to cure the layer? You might use ‘cura’ or some such to look. Maybe the retraction is leaving something? Have you run lots of calibration tests yet?
Hey, you might want to increase your layer height to about .2, and then set your retraction down (the number depends on your printer).
no im very new to 3d printing and have not done much in calibration other then like the bed and such

I have achieved a bit better Marvin on Printrbot Simple Metal (not cleaned after print; more photos of prints at home page gallery www.kopec3Dtisku.cz) thanks to additional area cooling with 120mm fan. The main fan (even with special shroud and better 40mm fan) is not enough to cool all sides (bridges and overhangs). Yes, and I have also upgraded to better hot end from default ceramic Ubis (E3D V6) and slicer (Simplify3D helps detailed printing a lot), but better cooling is a basic help here.
In your slicing settings take a look at the minimum layer time, it is possible that it is printing the small layers too quickly and not giving them enough time to harden. There should be a setting for this in both Cura and Slic3r, not sure which one you are using.
im using cura 15.04 and i had minumum layer time to 20 sec
