100% Infill Problem

Recommended Posts

Posted · 100% Infill Problem

Hello everybody,

my name is Michael and I am working with an UM 3ext since About a year. I have printed for a long time with CURA 3.6. 

Updated to 4.4.1. some time ago without using extensive. 

Now I tried to do an easy print job asap.

But I can not get a 100% infill in the real part. As you can see in the picture, the setting is 100%, but the preview as well as the printed parts have an infill pattern. (in 3.6. is works as expected).

Any idea, which parameter I have to change?

Thank you in Advance.

 

Michael

Hello Michael, can you send me a 3mf file by going to File > Save... in Cura and attaching it here? Thanks.

Hello maht,

sorry for the late response. I had no access to the model over the weekend.

I have attached the file.

 

Best regards

Michael

Is infill pattern ignored at 100%?

This is a mid-layer slicing with Concentric infill, but it seems like it uses diagonal lines anyway.

(Changing the percentage made cura 4.4. crash)

Yes, it is.

 

If you want it not to be ignored, set the number of Bottom Layers back to 8 (or so). By default, Cura prints everything as a bottom layer when setting the infill pattern to 100%.

Thanks for the answer. Sorry could you explain further what you mean in "If you want it not to be ignored, set the number of Bottom Layers back to 8 (or so). By default, Cura prints everything as a bottom layer when setting the infill pattern to 100%."

In other words, what do you propose to obtain a stronger bonding - which I think would be a continuous extrusions of the yellow (TPU) material around the blue ' PLA stitching'?

Its already good but I get inconsistent results for the four boundaries of a rectangle with this technique.

There is a setting in Cura named "Bottom Layers". Make it visible, and then see what happens if you change the infill density to 100. Spoiler alert: its value changes. Now change the value of "Bottom Layers" back to what it was, and slice again.

 

I have no experience combining PLA and TPU. I think that Ultimaker Breakaway material is a mix containing TPU, and it has been specifically designed to break away easily from PLA. That makes me suspect that PLA and TPU don't adhere very well. You may want to look in to the "Alternate Extra Wall" setting to improve adhesion.

Ok, you are magician. Thanks for sharing this hidden gem.

Using Engineering profile,  changing infill to 100% makes Shell-bottom layers go up to 9999999

I change that to 1 and slice. 

I can change the pattern to concentric giving me this

Grid (seems not 100% though)

It seems like a good option to 'catch' the 'blue pins' so I would have expected setting wall line count= 0 would make the grid go around the pins but no:

Maybe what I'm looking for is a slicing like:

What do you think could be close match?

Hello everybody,

thank you for help.

@ ahoeben: The Information with the number of bottom layers made it. In my case this was overwritten by "3" (whyever)

After resetting, everything works fine again. 

Best regards

Michael

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
