This was my first thought, too.
Yes, someone who’s really into 3D printing may be able to save money by printing everyday objects, but for those less dedicated, is it really worth pursuing?
My weekends are extremely valuable to me and (sorry) I’m not inclined to spend them tinkering with unfamiliar technology, investing time and effort into trial-and-error. It really is more ‘economical’ for me to buy something manufactured, and move on to something more fun or important.
However, I say that with an outsider’s perception, perhaps mistaken, that 3D printing is still something for professionals and dedicated hobbyists - once it becomes as quick and easy as microwave cookery, I can see it making more sense.
