Top thickness not the same as bottom thickness

Recommended Posts

Hi there,

 

I have searched the forums but not found specifically what I am looking for.

 

I am having trouble with my UM2 not printing the same top thickness the same as the bottom thickness.

 

I have the settings with PLA set as follows:

 

-Layer height =0.1

-Shell thickness = 1.2

-Bottom/top thickness = 0.6

-Fill density = 20

 

It only seems to do one 0.1mm run for the top surface leaving a poor surface finish on top.

 

I am very new to this so please excuse me if there is any obvious issues.

 

 

Any help would be much appreciated.

 

Thanks.

So the layer view only shows the top 4 or so internal layers so you have to slide down on that layer view control. I sliced your part and got the same 144 layers but when I slide the layer view down all the top surfaces seem to have 6 layers (I had to check many "top" surfaces.

Once you click on the layer slider once you can also use Shift+Up arrow or down arrow.

Ok so maybe I should look at increasing my bottom top thickness? Maybe because of the curve being rather horizontal in the lower stages and the 0.6 thickness is only measured in the Z direction it's leaving little layer height as it moves across/up the curve - if that makes sense?

 

I have added some pics of the print!

This is called "pillowing". You can read about it here. Your fans probably aren't at full power. Go back to cura settings and make sure the fan is at 100% well before this somewhat level area - possibly 1mm? 5mm is the default I believe:

Look at first picture - top left here:

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
