Here's an interesting article exploring the possible reasons as to why 3D printing has not gone mainstream quite yet. We are close to a tipping point within the market, but several things such as price, speed, design, and availability are holding it back. Within the next 18 months to 6 years it could happen. The article will explore what still needs to be accomplished. The article is here: http://3dprint.com/2827/mainstream-3...ting-adoption/

I would love to hear your feedback on it. When do you think 3D printing will go mainstream, meaning that the majority of the population has used a 3D printer or 3D printing service in one way or another?
