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: [attachment 45340 IMG_20141217_1048425.jpg] [attachment 45341 IMG_20141217_1048262.jpg] Thanks! https://reprap.org/forum/read.php?262,444687,444687#msg-444687 Tue, 19 May 2026 03:40:18 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,444687,445024#msg-445024 https://reprap.org/forum/read.php?262,444687,445024#msg-445024

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:

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.]]> jbernardis Printing Wed, 17 Dec 2014 17:47:08 -0500 https://reprap.org/forum/read.php?262,444687,444687#msg-444687 https://reprap.org/forum/read.php?262,444687,444687#msg-444687
