3D Printing: Evolution or Revolution?

It is not science fiction anymore... It was only in the science fiction movies that a small device is constructing a three-dimensional tangible object with the help of a computer. Now, it is the reality.

3D printing is an additive manufacturing technique (as opposed to conventional subtractive manufacturing that deals with getting rid of the excessive material) which means adding layers of material one after another to form the shape of the object.

3D printers are in use for more than couple of decades, they have been mostly used for making quick prototypes. As 3D printers get cheaper, faster and more capable, its use will get wider for prototypes and even for final products.

Since it is much cheaper, required less skills and less material use, many industries turn into using 3D printers for their prototyping and end products. Producer do not have to make a certain number of items to cover up the fixed costs, each item can be customized at the same low cost with minimal risk. In some cases, even transporting the item is not necessary, downloading the digital design file and printing it elsewhere is also possible. 3D printer prices get lower very fast, with this pace, even the end users could buy a machine and use it at home to customize or design own 3D objects. Some companies already started using for; rapid prototyping, medical modeling, fashion accessories, custom fit shoes or helmets and most importantly spare parts for expensive machinery.

I think 3D printing techniques will continue to evolve. As it gets more affordable, it will get more adoption. In my opinion, eventually, it would revolutionize the industries as well as individual users' capabilities to put their innovation at work.
