By now you’ve heard about 3D printers and you have an understanding of what they can do. It all sounds exciting and amazing but you still aren’t sure how these machines could help the average person. To help you get a better understanding 
I did a little digging. Here are some examples I found:
In an episode of “The Doctors” they used a 3D printer to create a 3D ultrasound. Nicole, who was pregnant with her 3rd child, is legally blind. Unlike most women Nicole didn’t have the opportunity to look at an ultrasound and see her child develop. By creating a 3D model of the fetus Nicole was able touch the model and know what her child looked like, how big it was, and what the sex was. 3D technology has allowed Nicole to experience an ultrasound like every other expecting mother.

In Westport Connecticut the Westport Library has adopted not one but two 3D printers. The library wanted to create a place where the community members could make their ideas come alive. They created the MakerSpace. Reference librarian Margie Freilich-Den said “the library helps its patrons with job searches, and the Maker Faire was just one step to encourage residents to "get back to our manufacturing roots" and encourage people with ideas to try them out.” The MakerSpace has helped many local entrepreneurs patent their ideas.

The biggest news about 3D printers is how one day they will become a household item. Unlike bigger manufacturing printers there is a smaller desktop version that you can use in your own home. Hobbyists use these 3D printers to create unique gifts and artwork for all occasions. Soon, if you break something in your home your 3D printer will be able to produce a replica for you. 3D printers were once a thing of the future and now the future of 3D printers is closer than we think.
