You can print other materials than just plastic. You are imagining today's 3D printers. OP spoke of a 100 year period. Computers are nothing like they were in their infancy, and there are many quotes of people claiming people would never need a computer at home.

Not that many, actually. You can't print most metals or glass (not without extreme temperatures), nor weaved materials. Maybe there are some ceramics that could be printed? You will also perhaps be able to print wood composites and a few other biological materials. Perhaps you may even print some electronics (though not something advanced like a microprocessor or FPGA).

If I'm missing somethign some examples of consumer goods you really think could be replaced by an advanced 3D printer that fits in an apartment or small-ish house (say, at maximum the size of a larger washing machine) would help a lot.

Again, you are comparing 100 years of exponential innovation to yesterday's technology. Yes, even today you can print many metals (gold, silver, titanium, aluminum, Tungsten, stainless steel, etc.) and you can print glass and fibers– let alone what will be possible in the future. And we aren't just talking 3D printing when discussing home manufacturing–there are reductive tools like CNCs and lasers as well.

You can walk through any Target or Walmart and see hundreds of items the could be made at home in the future.

You make good points but I think stores like Amazon with fast shipping are likely to be more convenient for people. It seems the majority of consumers would rather buy something than do it themself
