Yes but plywood is made of wood. A renewable resource. Also I must be int but nobody needs these kinds of houses and we don’t need them to be easily manufacturable. Tbh they look incredibly impractical. We need to build a lot of practical houses. If someone wants a house like this they probably have the means to get it handmade.

Problem is that plastics do not recycle too well. Every time you melt plastic it degrades. That means you always need new plastic and some gets lost. If you want to use recycled plastic you have to add virgin plastic every time. Also printing such thick plastic will take a long time. I don’t think it scales. If you want concrete forms, then generic preforms made from wood are way more practical.

Honestly don’t know why they don’t print the concrete forms in plastic and inject concrete, injectable cast concrete has been a thing for like a hundred years. You could do your raceways and plumbing runs and all then fill.

That would be a lot of waste plastic. Concrete is very heavy. That means the form hast to be extremely tough. For plastic that means a lot of plastic. At a certain point you won’t win anything there either.

As far as I have seen it’s very finicky. The concrete mixture is very special because normalnconcrete is not made for stacking layers and it’s also very sensitive to the weather. If it’s not exactly right it will start cracking.

I am not sure if anyone could yet demonstrate it at scale while being cheaper than traditional building.

I have the same case. Wiring was once a bit of pain but after that I had no problems.
