Small Objects

Hi guys!

I have a prusa I3 and have been printing with it for a few months, but recently have been trying to print small objects and it seem to have some difficulties. I print in PLA, and normally at 0,1 or 0,2 layer height, 215 extruder temperature, and printing speed normally around 50 mm/s. Also my sheel thickness is usually 1,2 mm. I have searched and the quality might improve reducing the temperature, what do you guys think? The piece I have done and have some problems is this:






Thanks!

215 is a bit high based on my own experience. I generally print PLA at 185.

Do you have a cooling fan on the printed object. I have one one the x carriage pointed downwards at an angle at the point of printing. It makes a dramatic difference with PLA.

I have a cooling fan pointing right at the end of the extruder. I started printing at 190 at the prints were total rubish, so I increased the temperature, I may try with 185, but I think it will happen the same.

It looks to me like your temperature is too high and could use more(better) cooling. As jbernardis said above I also experienced dramatic difference in quality when I ditched all those 40mm fans and mounted a proper(a lot better airflow) 80mm fan which blows across entire bed:
