Dense Support material is added between two parralel horizontal surfaces September 30, 2015 08:05AM |

Hello,
I'm trying to slice this part (see target.png picture) with two horizontal surfaces above each other.
The part is the "MiddleJoint" of some thingiverse object [www.thingiverse.com]
I'd like to have some support material sandwiched in between the two surfaces.
The slicing generates a dense (100% infill) material in between the two horizontal surface which is not some support material, (I have tried to check and uncheck "don't support bridges option" but it doesn't make a difference").
It seems as if the top of the bottom surface is repeated until the bottom of the top surface.
I'm using Slic3r version 1.2.9
Can you give me the correct settings to use to get a print ?
Thank you
William

That isn't a bridge so the "don't support bridges" option will have no effect.
What happens when you change the support pattern and spacing?
Post a screen cap of your print settings page for support material.

I see nothing wrong with the generated support material.
But if you want a better print orient it as defined in the original STL file then less support will be needed.

Here is the screen cap of the settings page.
Spacing 2.5mm rectilinear grid (working properly underneath the side of the piece).
Changing the support pattern or spacing doesn't change anything.
The normal infill of my part is 30% but between the two surfaces it prints 100% density.

@rhmorisson : I rotated the piece to have a greater contact surface area with the bed (I know I can enforce some support layer or raft and may try your suggestion). My problem is that the support material is not as usually for support material (It 's 100% infill and it takes hours to print, and it will be harder to remove without breaking my piece).

Can you please attach the gcode generated by Slic3r.

Then put it anywhere on the web where you have access and post the URL to the file.

Look at the 2D display - the fill is not 100% (or even close).

I added the gcode file on pastefile
[www.pastefile.com]
You can look using "pronterface" if you zoom in you will see the fill is dense.
And I can confirm it is dense (it's currently printing in 4 parts simultaneously (see picture) )
Thank you

That shape is going to be difficult to print with an FFF printer no matter what orientation (unless you use dense support printed with a multi-nozzle printer using soluble material for the support). My solution would be to cut the STL in half and print it as two U shaped pieces, then glue them together. If you print in ABS then acetone will form a chemical bond that is as strong as a single print. I believe that superglue works OK for PLA. The glue surfaces are large so it should be adequately strong.

I too found that the support material generated by slic3r 1.2.9 was far too dense.

Nor does the Slic3r 2d view!

I used printrun's "pronterface" [www.pronterface.com] : (The github branch have the latest rendering features)
git clone [github.com]
then read the readme to install the dependencies via an apt-get under ubuntu
then
sudo python pronterface.py
Although you can't cut at a specific Z directly you can either see by looking from the top at a specific angle or edit the gcode directly using Tools>Edit and remove some GCode to erase the top of the print to see as you would see during a print => then indeed you can see that it's a slicing issue because the infill is really dense.
But I'm sure there exists tools that allows to view GCode and not render some specific layers, but I don't know them.

What are you talking about?
Slic3r can do this!
Click on the Preview tab and then use the slider control on the right!
