An igloo actually spirals up, so each block when placed is support on two sides by an L-slot between the one below it and the one placed just before. If the 3d printed blocks were made to do this, they should just stay in place and become more locked in as blocks are added.
@@tomlouie2855 Another complication. Each block is trimmed at an angle so that the next block can't just slide off into the interior. Did I mention that I've made an igloo? It wasn't very pretty, but I did follow the basic Inuit process. I insisted on sleeping in it. They drip. The whole concept of an igloo is that it blocks the wind, and interior temperature rises to the melting point of water 32F/0C/ so it drips. (I was at 7000 feet (2100m) so these temps were a bit higher.) Fortunately my car was near by so I got some plastic sheeting to cover my sleeping bag. I used a machete, not having an illegal walrus tusk knife like Nanook. The design is pretty intuitive that you can see in the Nanook of the North documentary. That's a good lesson.
@@WillN2Go1 if the interior curvature of the igloo is smooth and consistently concave, then the meltwater might adhere to the surface and roll down the walls, instead of dripping down.
No, they dont use rubberbands because they are not cunts. they know how join the individual pieces with snow and voodka. Thats how it becomes a one piece and it doesnt separate
5 years ago this was made.... Hidden gem i found today
best channel for civil engineers l requested you pls upload as much models as you can this will help in learning.
Best regards from duomo florence brunelleschi, you have just revealed the true constructive principle 587 years later (1436-2023)
Your videos are always deeply good
Thanks you
Awesome video Dr. Brodland :). Very informative and creative.
yeah.
yeah.
yeah.
Very cool! Thanks for the video!

You should watch Nanook of the North or some of the other Canadian Film docs of Inuit building igloos.
He literally says so in the video. He even uses the correct word - helix - as opposed to spiral.
The mathematics for determining the 3d printed dimensions for a set of helical blocks for the igloo would be a neat exercise for students.

Thanks for the video,but what's material for this dome
He said at the beginning it was 3d printed, the two most common plastics for that process are PLA or ABS.
I imagine a geodesic dome does not need "rubberband" to maintain integrity vs any kind of force... or what are they weakness?
a dome is a chain spun 360 degrees around it's vertical axis and turned upside down
Where can I buy these so I can build one myself
what material is that?
He said at the beginning it was 3d printed, the two most common plastics for that process are PLA or ABS.
what kind of material is, this a thermocol
In the real world what do we use as a rubber band? Or do they actually make a giant rubberband to put around domes?
No, they dont use rubberbands because they are not cunts. they know how join the individual pieces with snow and voodka. Thats how it becomes a one piece and it doesnt separate
Pay attention tot he video he says they use a big steel ring made of rebar
Somebody make a tiny igloo cathedral
He has a weird way of paying rent, i think he lives in a small basement but this help yukon yankees build igloos so thats good

that's a weird wway to make breast implants, i like it!
Pretty sure inuit didn't have rubber bands
Thankfully, they at least had 3D printers!
shamir
awesome
