I swear that I asked ChatGPT about 3d printers that could print UV-stable materials 1m square and it listed a few at various price points that printed about 300mm square, so I figured it would be prohibitively expensive to print larger than that.
I could print a geodesic dome with foot-square panels, but why not a full hemisphere?
One of those printers only cost $500, but either ChatGPT refused to discuss something further and insisted on starting over, or I hit the 20 query limit.
Either way I didn't copy the information and when I asked about it again ChatGPT said "I never told you about 3d printers," and then it told me about different 3d printers, including one that cost a little less than $500.
What is a good greenhouse height?
Let's say that I can actually stand up in this one.
We will say it has an 8' radius, although I wonder if it should be more of a sphere.
Don't domes often have at least the bottom layer vertical, representing more than a hemisphere?
That would have a volume of 402.125 square feet and you would need over 400 panels.
That sounds annoying!
Here is a dome apparently based on a 4.75' sphere, with the diameter apparently just over a foot off the ground:
Garden Dome Bubble Tent 9.5 ft. x 9.5 ft. x 5.8 ft. PVC Screen Garden Igloo Geodesic Dome with Led Light Strings, Clear
It is $684 with just one one-star review.
Here is a dome based on a 70.865" sphere with the diameter just over 15" off the ground, $1,485, and rated 3.6 stars:
Garden Igloo - Improved Version V2 - 12' Walk-in Garden Dome Igloo
This isn't a dome, it has one dome-inspired connector on the top, and then just legs, like a spider wearing a poncho, or a clear umbrella without a handle for $245:
Haxnicks 9 Ft. W x 9 Ft. D Greenhouse
It doesn't seem to have much usable space inside and you need to use stakes to stretch the siding for maximum space?
This is 7" taller, 2.5' wider, and $345:
Haxnicks 11.5 Ft. W x 11.5 Ft. D Greenhouse
That sounds usable.
This sure looks like an actual dome.
5v?
$500: 9.5' W x 9.5' D Hobby Greenhouse
I don't see any other dome or dome-inspired greenhouses for sale.
