Problem with 3d printing on detailed geometry

[Kruno3D 2]

Hi all,

I'm trying to 3D print Astronaut Phil, and I have trouble with his fingers.

Everything else comes out flawlessly, but only fingers are mess.

Model is scaled to 50%

Using Cura 2.7.0

Ultimaker 2

Material PLA

Temp 200 - 210

Speed 40 mm/s

Cooling 100

Tried playing with material temperature, lowered the temperature, but it seams to turned out even worse.

I also played with Motion settings, but no improvements on end result.

So I believe it is some setting in Cura, that causing this problem.

Any Ideas?

If that is printed upside down (thus as shown in the Cura-view above), then the overhangs are probably too big: then the printer always has to print the outer layer half in the air without anything supporting it, so it deforms: it sags or curls up. Try printing this as slow and as cool as possible, and maybe try placing a fan in front of the printer. I would try 190°C and 25mm/s, with a desktop fan in front at low speed, and see what that gives.

Hey Geert,

thnx for feedback.

I tried as you suggested (only without additional fan, just because I don't have it atm), and with no better results.

Every tryout with different set of temperature, and lower speed, has resulted with the same outcome, and no improvement at all.

This is why I believe that something else is causing it.

Any more ideas, beside temperature?
