My Top and Bottom Layer Is Not Solid When 3D Printing

[Help 0]

I have been trying to trouble shoot this problem for a while now. Every time I try to print an object, the top and bottom layer do not print solidly. Any suggestions on how to fix this problem is much appreciated.

This is tricky as you aren't showing the sides of the print.

 

This is called underextrusion.

 

But when this happens on the bottom layer then 99% of the time it is because the nozzle is too far from the print bed.  On an ultimaker sdon't relevel - simply adjust the 3 screws equal amounts to bring the bed up.  This is a very common problem (bottom layer underextruded) - maybe in the top 2 most common problems.  It also causes the parts to not stick well.

 

However if this is happening on the top layer you could have other issues.  What kind of printer is it and please show a photo of the sides and top.  It could be simplyl that you don't have good infill (not dense enough).  Usually 20% infill is enough along with 6 top layers.

 

The sides of your part may also be experiencing underextrusion.  That has a different look to it.  I'd like to see a photo of that as well.
