Undoubtedly, 3D printing is a groundbreaking technology with the potential to change the world. However, the technology has been over-hyped lately, so much so that some experts anticipate consumers will be largely disappointed with the technology’s reality. Amid reports of some of the most important 3D printing projects, some projects over-state their potential, are too expensive to ever be practical, or are just plain useless.
In a classic case of “just because you can make something doesn’t mean you should,” a group of eighth graders in California printed a set of brass knuckles just for kicks last year, Bloomberg Businessweek reported. To be more accurate, the hard-plastic version of the weapon used most prominently in gang fights can’t really be called “brass.” But given that traditional, real brass knuckles were pretty unnecessary to begin with, it’s fair to say that the 3D design file for the weapon is pretty unnecessary for a 14-year-old.
