Difficult to believe it's been 10 years since I wrote the article "3D Printing in 2012 and beyond". It would not be feasible to come close to covering everything that has changed within the industry let a lone the world at large.
Arguably the most important topic for business ignored in the aforementioned article is Bitcoin and its questionable sidekick cryptocurrency. In fairness Bitcoin was only 3 years old in 2012, and worth around $5 to $10 a coin.
Unfortunately there has yet to be a meaningful impact on 3D printing and manufacturing in general. This of course is expected to change.
There are quite a few tokens that have the potential to in some way cross paths with 3D Printing (for better or for worse). In the last two years there has been a notable uptick in the amount of articles available with both Printing and Blockchain in them.
