I think most people will use 3D printers to print stuff like cups, toys, key chains, and other small items where plastic is good enough unless you need a more durable metal item printed from a more expensive 3D printer which prints metal objects, and use more expensive metal to print out 3D objects.
A lot of the time people use 3D printers to print out a model of something like a phone case, and how something will look and feel, and latter hire a factory which can use molds, machines, and people to more quickly build many items per hour. I think cheap plastic models would be good enough to see the basic look and feel of an item.
