When thinking about smart, lean ecosystems, 3D printing is inherently at the forefront of any discussion. 3D printing is at the peak of smart manufacturing, allowing anyone around the world to print any design. Likewise, in a space such as manufacturing which is known for its “subtractive manufacturing” methods, 3D printing involves “additive” technologies which reduce waste and time. With so much up-side, why haven’t more companies adopted 3D technologies? This is a difficult question to answer as each company has a unique response. Because of this, I thought it would be interesting to include the article “30 Most Innovative 3D Printing Companies 2016” (https://all3dp.com/best-3d-printing-companies-startups-to-watch/) to show not only which companies are actively utilizing this technology, but how they are doing it. These companies, and many others which did not make the list, come from countries all over the world, each with a different use for 3D technology. This exemplifies not only the flexibility this technology possesses, but the potential it empowers across virtually all future markets.
