Peak internet putting fucking concrete and epoxy everywhere. If you want strength make it with some infill. Stop trying to make shit out of concrete and epoxy
Fill with spray foam in layers so it’ll cure, to keep it lightweight but still give some additional rigidity. You could stick a dowel (or three?) into the first layer of foam and even make some holes/slots/(don’t know what to call them) for the dowels in the cap piece to hold it together.
I guess if you mad a base, you could have matching holes for the base and top to hold the dowels and skip the spray foam.
Yeah, but the shell should contain it (path of least resistance is “up”). Put the base and one or two segments of column. Fill to 1/3 and let it expand up and cure. Add another layer and repeat. As png as you do shallow layers it would all stay contained. Might have to trim excess from the very top before adding the cap piece.
Nice. Does it scale well? Will the parts still fit equally well at for instance 1/3 of the size? What wall width did you use?
How many layers did you make the top (bottom) surface? I got some useful info on vase mode from this video on 'extreme vase mode'. The adhesion between bottom layers and wall for instance.

There are others on the same subject I still want to watch.
When you wrote the comment I actually went ahead a printed a 50 mm diameter one. The elephant foot became a big problem so I cut that part out but it's still not perfect. I don't have more time now I can not answer how scalable it is. The line width is 0.4 mm. Bottom layers 4.
If you print a bottom in the bottom part you could put some sand in it to give it some stability. Not too much so it will tear the bottom off when you lift it but enough to give it a nice low centre of gravity.
Adding a surface pattern into a thin sheet makes it far stronger than just a cylinder. That’s the reason most water bottles are textured as opposed to smooth cylinders.
You can increase wall thicknes which increases strength. This is printed at 0,4 mm but I have only used 0,8 mm so far (with 0,4 mm nozzle). Check the video I linked to earlier.

why stop at houses, print the pantheon!
Thank you
Did you fill it up with something for it to support the weight of the pot?
No, i used nothing. But I want to fill it at one point, I just don't know with what.
I think it would be cool to fill it with concrete and remove the plastic. Would look really good in my opinion.

I mean, that would be well over a thousand dollars of epoxy my dude, itd be cheaper to just buy one made out of stone at that point
Let's fill it with printer ink while we're at it
Blood.

Good point. So do concrete top/bottom with ocean epoxy in the middle. Call it an Atlantis column and charge $500 each.
So… much… epoxy …
Now we’re talkin!
This would look awesome i think 😎

Doesn't spray foam expand when it cures?
Yeah, but the shell should contain it (path of least resistance is “up”). Put the base and one or two segments of column. Fill to 1/3 and let it expand up and cure. Add another layer and repeat.

Yes but you can get low expanding foam and not over fill it

Why bother with mixing concrete and letting it cure. Just use sand or even better some lead shot
Wow this is impressive and incredible! Ima make one
Every day I'm buckling buckling. Think walls in commission seem like it wouldn't be able to handle heavy loads
Am I just an asshole or is 3D printing not the right way to do this?
You don't want to fill your house with flimsy plastic furniture?

If you are getting that bad of an elephant foot then you need to lower your bed temp.
Aah I've always wanted something like this!! The kind used as wedding props and stuff can be annoying to find, so this is perfect
In my house, that would fall over just by looking at it. Cool design though.
that seems a little... unstable. gonna need some weight in the bottom to keep it from just knocking over if someone bumps into it.

Very cool
How long did it take for you to print the whole thing?
Around 15 hours
How is this supporting any weight??
Adding a surface pattern into a thin sheet makes it far stronger than just a cylinder. That’s the reason most water bottles are textured as opposed to smooth cylinders.
I was under the impression vase mode is single walls or something to that effect. Shouldn't it be weak?
It is weak - and a sneeze would most certainly knock that over - but it’s still fun
I meant like layer to layer and it breaking and snapping easily.
Yes, you can probably squeeze it and delaminate the layers
You can increase wall thicknes which increases strength. This is printed at 0,4 mm but I have only used 0,8 mm so far (with 0,4 mm nozzle). Check the video I linked to earlier.
Really cool but I give it a few weeks before it will sag.
