- Worry Meter: 75%
While the potential for 3D Printers is incredible, there are a lot of issues that can happen with them. Of course, this really all depends on the type of printer we’re discussing though. Printers have to be given a raw supply of materials to make things, which usually results in the use of cheap materials such as hard plastics. However, if you wanted to, you could supply other materials to truly make something dangerous. This became a major worry years ago when guns were being made by them. Of course, most of the early guns were not very effective, but this has changed as technology improved.
One could now print out an AR-15 style gun or an assault rifle. None of which have gone through testing, and the user has not even had a background check. This was proven to be a big problem in 2013 when a California made printed a home-made AR-15 and murdered 5 people. He was denied the opportunity to buy one due to mental health problems, so he just printed his own version. 3D printers are some of the scariest technology out there due to this type of thing being possible. 3D printers have become a lot more affordable too. What’s worse is that there are websites that show people how to print guns!
