This is asinine. How many of us spend $1000 in a few years on items that could be supplied by 3D printing (ie not consumables, clothing, toiletries, or detergents)? I've set up a comfortable home, lived a decade, and moved across the country, and I doubt I've spent half that on 3D-printable items, even including metal flatware. And that's not even accounting for the materials and maintenance costs of using the printer, and it's assuming well-curated libraries of extremely reliable designs. Maybe if you have small children with a constant demand for new plastic toys; maybe if you're doing a lot of home repairs. Otherwise, it may make sense to rent time on a convenient printer, and they could be fantastic for light industry. Stores may even manufacture goods instead of stocking them. But the economic argument for a $1000 printer in a home that maybe spends a few hundred on theoretically printable goods in an unusually expensive year is clearly nuts.
