Hi everyone! I'm currently a student at university and got a 3d printer as a gift to help me with my studies, however I seem to be having issues with the quality of prints, with the shell somewhat distorting at higher layers, I believe this is because it's cooling too slow and allows the shell to be free to distort before the next go over, I'm working with a CTC duel extruder using makerbot, any advice from you guys would be great!! Thanks

Slow down print speed. If your printing PLA use an active cooling fan.

My printer doesn't have an active cooling fan, only the fan for the extruder heat sink, do you have any suggestions on the best ones? 

Thanks!

What i done when i first got my Printer and needed a cooling fan was. Printed a cooling fan duct and used the fan off the second extruder. just wired it to the extruder fan that i was using and put a switch on it. later on i ended up buying a fan off ebay for a few dollars and using that. thats what i still use to this day without issues.

Yeah I had the same idea as I don't use the second extruder, I've attempted with a simple desk fan and it seemed to completely solve my problem so I think I'm going to continue using this for now!! Thanks man
