3d printing technology has rapidly advanced over the past few years, to the point that they’ve begun printing houses. Yes, real houses. The kind people live in. We’re not suggesting that you need to invest in a home-building 3d printer, as those are rather large and might be out of your budget. But 3d printing can be used for all kinds of smaller things as well, from artistic models to home furnishings. And 3d printers are really fun to play with. If you know someone who needs a new hobby to keep them out of trouble, this could be just the thing.
