How to infill....

[PhillHS 0]

Hi there,

 

Using a Dremel 3d45 printer with the dremel plugin.

 

In my current project I have a 3mm thick, though it may eventually end up being larger, rectangle (92x245mm), which takes ages to print even on the quickest settings. This seems to be as it it is being printed as a big solid piece. Is there a way to slice it so that the internal part of the box is not completely filled in If so how would I go about this?

 

Cheers.

 

Phill.

Hiya!

 

Depending on your layer height, the default for top/bottom is to have a top and bottom about 0.8mm thick.

If you're looking at the basic settings:

the top/bottom height is the one on the right after Shell Thickness. If you have it set to custom settings view:

It's Top/Bottom > Top/Bottom Thickness. If your part is 3mm thick then if the top/bottom thickness is set to under 1.5mm it should print with infill.

 

If the settings look good and it still won't work, please post your Cura project file (.3mf, get it ready to print then go to File > Save Project) so us boffins around here can have a look and see if we can spot a problem.

Thanks for that, seems to be working for me now 🙂

 

Now if I have parts of my design that I want completely filled, as they are say supports that need a little more strength, is there a way of doing this?

 

Cheers.

Little more complicated but yes:

So if I have this and want to make the legs solid:

By default the legs have the same infill as the rest of it:

 

I want them to be solid.

1. In prepare mode, select your model and then using the support blocker tool  click anywhere on the model to create a blocker:
   
2. Go back to the move tool  and click on your blocker to make sure only it is selected:
   
3. Now use the move and scale  tools (turn off Uniform Scaling and turn on Snap Scaling to make it easier to work with) to make your blocker cover the whole leg (it doesn't matter if it's a bit too big as long as it's not touching anything else. You might have to enter the numbers into the scale box manually to get it exactly right:
   
4. Open the per model settings tool  and set it to the third option, which makes it modify whatever's inside it;
   
5. Leave all the existing settings as they are (the 0 basically means "don't change this"), then click Select Settings, scroll down to the Infill section and check Infill Density:
   
6. Back in the per model settings, scroll down to the bottom of the list and the Infill Density will be there. Set it to 100%:
   
7. Now if we go back to preview mode:
   
   Good, but not 100%. The problem is that I'm using the Cubic infill pattern for the whole model. If that's not a problem for you, skip to step 8.
   1. Go back to your per model settings, click Select Settings again, then scroll down to Infill and check Infill Pattern:
      
   2. Close the select settings box, and now for a pattern select one of the ones which is capable of 100% infill (Lines, Zig Zag or Concentric, off the top of my head):
      
   3. Now we have a full leg!
      
8. Right click it and click Multiply Selected and enter as many more legs as you need (for me it's one, but if you want to build an octopus, that's fine by me) and click Ok:
   
9. It'll probably put it... right next to the existing one:
   
   But it's fine! We just need to move it:
   

Now if we hop back to preview mode... two solid legs!

And my infill on top is still fine!
