trouble with last layers

[trekbonita 0]

hi, im using the ender 3, the texture start printing ok for 2 layers after the initial layer, and after that it starts touching the printed parts and ruining the texture. been trying it for 1 week modifying all the pattern, some of those improve it like make overhangs printable and turning off the optimizing option, but im lost.

Is the top photo showing the top layer?  Is the part supposed to be

a) solid or is it supposed  to be

b) have interesting geometric holes on top

??

 

If A then this is called "pillowing" and is solved with better cooling (more fan) but if that's not an option for you then you can also just print a bit slower (try half speed) and also add more top layers.

im already on 5 speed on cura, yes the photo shows the top layer, should a force to add like 2 top layers on the slicer?

You didn't answer A or B to my question.  I tried to make it easy.  I can't answer your newer question until you answer mine.

 

New question: what is "5 speed"?

the photo is showing the top layer it is suppose to be kind of a mesh with honeybee pattern

Oh yeah.  We call that pillowing.  You need more cooling or slow down or more top layers.  Or a combination of all 3.

 

google for pillowing and 3d printing and you'll see other examples and discussion.
