#Printed Honeycomb Panels & Modifier Funkiness
dreamy mauve
Is there a way to stop the holes from creating this ripple geometry using modifiers?
I dont need the extra thick band of yellow perimeters.
All I want is for the for the orange outer perimeter of that structure to propogate all thh way down to Z=0.2
...and the sparse infill (red) to directly contact with the perfectly parallel orange walls
cloud crystal
Those are the walls aren't they? You have walls set to 8.
dreamy mauve
@cloud crystal I need the edges of the printed panel to be 8 perimeters for structural integrity.
Furthermore, having 8 perimeters for the structure shown in the photo below doesn't seem to cause any unwanted, extra perimeters
If i remove the holes from the CAD, and use a modifier to set bottom layer in that specific area to my required thickness, i get a somewhat desirable result
However, as soon as I add that hole geometry, say even a negative modifier, it brings-back the extra perimeter that I don't need
cloud crystal
Sorry, don't think I will be helpful, I don't really understand what you are referring to there. Just thought those looked like walls, and saw you had walls set to 8. If you want to know what those lines are, or want to share with those of us on discord, select line type and show that in the screen shot too.
cloud crystal
yeah, so those are walls. If you want fewer walls, can't you just specify fewer walls?
dreamy mauve
If I specify just fewer walls within this area, it gives me even more internal perimeters than shown above
cloud crystal
But fewer walls everywhere works right, just doesn't give you the wall count you want on the outside?
dreamy mauve
But fewer walls everywhere works right, just doesn't give you the wall count you...
that's correct
cloud crystal
You'd have to play around with per object wall settings, but this is the first time I have heard of someone wanting to control wall count by part of an object. You might have to somehow make them separate objects, or even tweak your model to fool orca into getting walls you want where you want them.
But if you don't want 8 walls around the cylinders, why have 8 walls on the cylinder object?

I was considering tweaking the CAD object itself using a project for the overall edges - then an offset sketch, but didn't want to have to do it if I could get around it in slicer :/
cloud crystal
I have seen people add false walls in an object to force orca to give them extra walls in certain places.

What cylinder? the negative cylinder?
changing the walls on a negative object doesn't affect the slice
cloud crystal
Yeah, the negative cylinder has wall count set to 8 too in your screenshot.
#til, didn't know that.
cloud crystal
I've tried to do some fun things in the slicer as well to get around firing up fusion, but it definitely has it's limits. One thing you could do is take the outer walls, offset them in cad a few mm in, then say use 4 walls and it would produce 8 if the two sets of walls you had were the correct distance between each other.

That's exactly what I was thinking, tbh
cloud crystal
Can you change wall count with a modifier? Like take the center of the part, put a modifier on it, with a lower wall count?
dreamy mauve
It's just the extra linework was a bit disconcerting

doesn't work, haha, i tried that too
That's what's happening here
The modifier area has 2 walls
but the main part wants to add 8 extra walls around the modifier volume
😅
cloud crystal
Sort of like this maybe?
dreamy mauve
I think it might not be possible within the constraints of the current Slicer version
If you notice, in both your and my example, there's two orange lines (external perimeters) where the volumes meet
I guess, wherever an external perimeter is defined, internal perimeters are always sure to follow
in the case of overlapping volumes, this results in two sets of external perimeters :/
cloud crystal
That part doesn't matter does it? I mean it's not really an external perimeter, it's just labeled that way.
It seems clearly inside the part to me.
dreamy mauve
in my model, the honeycomb containing volume is enforcing the 8 perims
cloud crystal
Or am I misunderstanding it?
dreamy mauve
whereas, I'd rather it consider the modifier body region as part of the same single volume, so that only internal perimeters or solid infill are present
cloud crystal
?
Perimeters are perimeters though. They are walls. It's only really an external wall if it's on the outside. That preview might label it an external wall in the center but that's only because it's not smart enough to see it's actually an internal perimeter.
I mean you can try to fool orca with cad, but it will still label those things as external perimeters even though they are internal. I am failing to see why it matters though. Do you think there is some structural difference caused by the label "external perimiter"?
dreamy mauve
My set-up is more similar to this
same problem though
it puts 8 perimeters on the inside though
even though the modifier is still of the same "part"
cloud crystal
This is what you wanted though right?
dreamy mauve
8 perimeters from the main body:
1 yellow
2 yellow
3 yellow
4 yellow
5 yellow
6 yellow
7 yellow
8 orange
2 perimeters from the modifiers:
1 orange
2 yellow
dreamy mauve
This is what you wanted though right?
it is not
the modifier area is where i want ALL perimeters to be isolated to
I do not want any excess perimeters "leaking out"
from away where the modifier is
cloud crystal
Can you draw a picture maybe? I'm failing to understand your explanation. What I uploaded is how I understand your request unfortunately.
dreamy mauve
the modifier is only as thin as the geometry it's sitting on
yellow overlapping with the blue
i only want perimeters to exist within the yellow area
not the blue area
but slicing gives those excess perimeters that exceed the bounds of the modifier
cloud crystal
Oof. Sorry. I don't get it. Hopefully someone else can help you out.
But at least today I learned I can make an object have 8 outer walls and 2 internal.
cloud crystal
I don't see how that is different than my example.
dreamy mauve
this uses the same exact settings as your example
8 perims on main
2 perims on modifier
cloud crystal
No, that has 8 on the inside, mine has two walls around the circle in the center.
I mean, I uploaded a picture of it. Mine clearly doesn't have 8 walls around the circle.
dreamy mauve
you need to widen the X & Y of your main cube
cloud crystal
I never shared the settings of my example, I just asked you if it was what you wanted, so you couldn't have used the same settings.
dreamy mauve
you'll see the 8 perims
that's why i made a wider version
i used a cube here, but same idea
cloud crystal
you'll see the 8 perims
I don't see that. I wonder why you think I will, when you don't know how I made mine? Bigger xy, still no more internal perimeters.
dreamy mauve
basically, i want it to be like this
I don't want a second set of internal (yellow) perimeters radiating from the edges of the inner modifier volume
i.e. the portion I've covered up with purple rectangles
cloud crystal
I don't have extra walls on mine.
dreamy mauve
can you switch to plating mode?
it looks like your modifier volume xy bounds are only slight undersized compared to the main body
cloud crystal
You want to see my 3mf?
dreamy mauve
maybe tmrw, I can't keep getting out of bed (at 3am) to use Orca on my desktop 😅
can you just send a screenshot of your plating mode, not the slicing preview?
cloud crystal
cloud crystal
That wouldn't give me lots of external walls, some infill, and few internal walls though.
Which best I can tell is what you want.
I mean I can make it not work, but why do that?
cloud crystal
I'm not either. I'm discussing the end object printed, but you keep talking about the process of getting there, so it's hard to understand if I even get the end goal correctly.
But if the goal is lots of external walls, then infill, then few internal walls, then this works.
dreamy mauve
the goal is lots of external walls, sparse honeycomb infill, then walls for mounting points within the confines of a modifier
dreamy mauve
these bounds
dreamy mauve
however, they're consistently spilling out
cloud crystal
So in that description, I don't know what you mean by "spare" then I don't know what you mean by walls for mounting points within the confines of a modifier.
cloud crystal
The mounting points, those are actual holes right? Like the hole I put in my cube example?
dreamy mauve
correct, the hole represents the mounting point
cloud crystal
So to me that is exactly what I have shown.
dreamy mauve
however, in my example, it's not just a hole with infill around it
it's a strip of solid 100% lines and a few holes patterned into it
it needs to be load bearing
Tomorrow, I'll re-establish the baseline scope of what I'm trying to do
as it stands, I'm too tired and need proper access to Orcaslicer
dreamy mauve
I finally got my head around it.
While I was trying to create/use modifiers based on the structures/geometry I wanted to keep,
your strategy was to create/use modifiers based on the structures/geometry I'd need to specify as infill
Old strategy above the mounting strip;
new strategy below the mounting strip
Old strat
new strat
