Glad to see new building techniques being attempted in real world scenarios. 3d printed structures will be most compelling when they do more things that are difficult or impractical with traditional techniques: curved walls, built inside, ornamentation, patterns, etc.

There is nothing you can’t do with classical drywall. Curved walls, ornamentation, patterns, integrated furniture… you name it. 3d printing has a huge limitation here - you need support to print over empty area. I am sure it’s not fun removing concrete support pieces from huge concrete structure without cracks.

Okay, I name compound curves. Can I do that with drywall?

[lnsru]

Yes you can. It’s the frame behind drywall then. Probably CNC cut plywood construction. And it’s more art than anything you might get from standard construction company. And crazy decorative art can be made from gypsum and integrated into drywall.

It’s a trick question sorta.

You can’t make a compound curve out of sheet material. Drywall can bend in a single axis only. If you add a second axis (compound curves) it won’t really work. Think about trying to drywall a sphere. The best you can do is a high poly sphere.

It’s not a single sheet. It’s multiple sheets covered in gypsum shell. More sculpture than drywall. Relative worked for riches, egg and bells were his projects 25 years ago. It’s just many many hours designing it and even more sanding to get perfect shape. There are now 3D printers for such projects: https://www.voxeljet.com/3d-printing-solution/sand-casting/ Since it’s cheap and fast today riches lost interest.

That's what the mudder is for ;)
