Editor's Notes
- Introduction I'm sure the majority of you have heard of 3D printing. Even if you've never actually used one, you've certainly seen them in one of their numerous representations in popular culture. Whether you're watching people print inventions in Big Hero Six, or an entire copy of themselves in the Big Bang Theory, 3D printing is always a sign of advanced technology.
- What it is generally But what exactly is 3D printing? Where did it start? And How is it changing everything from manufacturing to medicine? 3D printing takes a 3D model of something and makes it real.
- It is a form of additive manufacturing where material is deposited, layer by layer, in precise geometric patterns, until it creates a printed object. This is different from many forms of manufacturing which use "subtractive" manufacturing, where material is taken away like drilling, milling, carving, and more.
- 3D printing is probably a lot older than you might imagine. A report on it was first published in 1981, and a functional form of it was patented in 1984. This makes 3D printing older than GPS, digital cameras, web browser and much more. Though there have been improvements in the speed and quality of printing, the technique has remained mostly the same since the 1980's.
- SLA The first 3D printing form invented was stereolithography, or SLA, 3D printing. It uses a laser that is shone in patterns layer by layer on a vat of light-sensitive liquid resin. As the laser hits the liquid, it hardens into plastic and creates the printed object. Another similar form is Digital Light Processing, or DLP which does the same but with a projector screen instead of a laser.
- SLS The second form of 3D printing invented was Selective Laser Sintering or SLS. This uses a laser to heat a small bed of powder composed of small grains of nylon and elastomer. The places hit by the laser then bond with each other and solidify. This form of 3D printing is sometimes preferred because it doesn't require support structures.
- FDM The final and most common method of 3D printing is the one most people are familiar with. This is Fused Deposition Modelling, or FDM. In this, a thermo plastic filament is heated until it melts and then pressed layer by layer into a 3D shape.
- History Though the general technique of 3D printing has not changed much since 1988 when FDM was invented, there have been a number of recent developments. In 1999, the first 3D printed organ, a bladder, was successfully implanted, and many more have followed. In 2006, the first 3D printer was commercially sold, and in 2008 a self-replicating printer was made.
- Intro to Industries As the cost of 3D printing has decreased and its speed has increased, different industries have started applying it to their own processes. 3D printing is still progressing, but we can already see the affect it is having on different sectors of the economy.
- Manufacturing The most obvious application of 3D printing is its use in manufacturing. 3D printing can allow companies to produce customizable products for each order so they don't need to keep unnecessary stock, and allow them to design without regard for ease of manufacture.
- Start-up This kind of manufacturing can especially be good for start-up companies that need to build prototypes. The speed and cheaper price of individual models can allow any problems to be spotted quickly and easily and allow for ease of display.
- At home production 3D printing may have other impacts on the manufacturing industry though, as with the lessening in price, individuals may have printers in their homes. There may be a transition where people can buy plans for objects online and manufacture them themselves.
- Aerospace 3D printing is already being applied to the aerospace industry, with everyone from Boeing to NASA using it to print replacement parts. They allow for more precise parts that are cheaper and easier to individually print.
- Automotive The automotive industry has similarly applied 3D printing, for replacement parts, and even the construction of entire cars, with the first 3D printed car being made in 2014.
- Construction The construction industry has also made use of 3D printing, with an entire apartment building being constructed with 3D printing. Though the printers used to accomplish this are very expensive, it can cut the time needed to build from years to mere months.
- Medicine One of 3D printings most known applications is in medicine, but many people are unaware of just how useful and widespread it is. Already, 90% of hearing aids contain 3D printed components. Additionally, bones and organs can be printed and personalized so that they fit the user. Finally, surgeons can practice on 3D models.
- Disruptive Tech With all of these applications, it should be clear that 3D printing is a huge part of the world around us, and will only grow. Still, as more and more industries employ it, there are several impacts this has on our economy and society as a whole.
- Negatives 3D printing can take away jobs as printers are used to do things people had previously done, these are especially low-wage manufacturing jobs. It could lead to varied standards and make it difficult for the government to regulate products. It could also completely change the structure of manufacturing of people print their purchases in their own homes.
- Despite these negatives, 3D printing reduces cost and risk of production, and makes it faster. It is because of these reasons that it has been implemented in so many industries already.
- Conclusions Many of these problems with 3D printing, like the change in the manufacturing process, are still a number of years away. Even so, the benefits of 3D printing vastly outweigh it's purported defects.
