Six 3D printable inventions to help make the world a better place

The concept of 3D printing in manufacturing is in its infancy but it has created quite a buzz so. Here are 6 of the most useful inventions created by 3D printing.

3D printing has brought revolution in the industrial sector in true meaning. Starting with small scale, it has now gone to the industrial scale and has also secured its position in the International Space Station as well. Amazing inventions are happening in the manufacturing industry with the help of 3D printing.
It goes beyond any doubt that 3D printing has the potential to change the world for a better place for living. Rapid prototyping and additive manufacturing is getting cheaper, easier and more convenient. If you haven’t got enough of 3D printers yet, here are six latest inventions by 3D printers that are certainly changing human lives for betterment.
1) The E—Nable Prosthetic Hand:
The first one in the list is certainly the E-Nable prosthetic hand. This has come out as a boon for the young children with disabilities. A number of hands are stored in the files that can be printed very easily and at a fraction of cost compared to traditional prosthetics. They may not be fancy when considering the look but those are more than capable of serving the purpose and changing the life of others at a price of around $100.
2) Stethoscopes—Helping Doctors Diagnose Patients:
The next invention is from the medical field. A Palestinian-Canadian doctor named Tarek Loubani has invented a low-cost stethoscope that can be created with the help of 3D printing and a few other components most of which are available locally. This is an amazing invention and doctors have admitted that it works as fine as traditional stethoscopes.
3) Doggie Wheelchairs: If you think that it has only changed the lives of humans, you need to think once again. With the help of 3D printing, you can create a customizable wheelchair designed for your dog only. This is easy and also less expensive.  
4) A Micro-Wind Turbine:
If you are anywhere from Nebraska, you must have noticed the huge wind turbines used to produce electricity. And you will be surprised to know that you too can create a smaller version of these wind turbines for your personal electricity supply. Different designs of wind turbines are available with varied size, shape and efficiency. You can create your own mobile power station through generator and can be used in disaster-attacked areas where there is no access to power.  
5) Drones—Because Everything’s Better with More Drones:
The importance and use of drones are increasing with time. While in one hand this is a preferred means of entertainment on the other hand, it has a professional use as well. Now with the help of 3D printing ability, anybody can build such drones with the available local components. One can customize the drone to meet specific requirements as well.
6) Hydroponics—For Growing Food:
Foods or seeds can be grown in different manners and they can be grown in the space as well. Hydroponics is the way that can offer great results. And all the credits go to the team of 3D Ponics. They have come up with an open source system that can be created by using recycled pop bottles and of course 3D painting. So, now you can grow your plants in your convenient place with the help of 3D printing and pop bottles.
3D printing is already creating real differences in the manufacturing field and this will continue doing so. Even the biggest critics of 3D printing would agree that it has never disappointed.
