We’ve heard more and more about the concept of 3D printing in the last few years, but 3D printing has actually been around since 1984. 3D printing works like an inkjet printer, but uses desired materials “printed” in layers instead of ink to create an end product. 3D printing can be seen in a variety of industries like automotive, aviation, manufacturing, and medical. As 3D printing is becoming more prevalent, we want to take a quick look at its timeline. 
The Beginning
In 1984, Charles Hull invented stereolithography, which is the technology that allows an object to be created via digital image and data. Later, in 1992, the first SLA machine was created by 3D Systems that could create products overnight. The machine utilized a UV laser solidifying photopolymer and a liquid to create the 3D parts layer by layer. Following 3D Systems, was RepRap, which took an open source approach to 3D printing in hopes of allowing people to create everyday products.
The Early 2000s
The early 2000s saw drastic improvements to the thought of 3D printing. The first selective laser sintering machine became viable, fusing materials into actual 3D products. Objet, a 3D printing company, later created a machine that allowed printing in multiple materials. Architects were able to create inexpensive 3D objects, a person walked on a 3D prosthetic leg, and printed blood vessels all saw the light of day.
Now
2011 was big for 3D printing. The first printed aircraft was created, along with the first printed car. Printing in gold and silver also became available. Now, 3D printing is available to everyone; from Makerbot to RoboX, anyone can buy a printer. Two updates were released last week from the 3D printing world; Students at MIT created 3D printed ice cream and Home Depot has started selling the 3D printer, Makerbot, to consumers.
Future
3D printing will make today unrecognizable in 50 to 75 years. A new world is being opened with the help of 3D printing. More people may soon be living beyond 100 years old thanks to bio-printed organs. In the near future, entire neighborhoods may soon be developed . Will you invest in a 3D printer?
