What about 3-D printing for backyard hardscape for higher-end consumers, not homes for refugees?

Mass customization for benches, sculptures, playhouses, fountains. The value is in getting something unique, not speed or cost.

Or does that only make sense after my getting a $4k quote to build a rectangular concrete bench in coastal California? (Actually, I just went back and checked—it was $14.5k for an 18 foot concrete block bench with a plaster finish to look like poured concrete, with an actual concrete version even more expensive).

I made an outline of a business doing this a few years ago: sell yard printers, proprietary media, and object library digital subscriptions to contractors, along with training/certification, but I never went down the rabbit hole to figure out a cement mixture and scale up my Ender-3.
