3D printers started out insanely-expensive and only industrial users and researchers could really afford to own one. They're still really expensive -- but now there's models designed to sit on a desktop just like an office printer would, except that they print objects and not pieces of paper. As a guide to the best desktop 3D printers of 2015, I wrote up an article about what there is out there, how much it costs, and where to find supplies for the various printers. Now most of these cost in the $500 - $1,000 range (with some going up around $7,000) so I suspect that many 3D printers are out of reach for most of us but it could still be worthwhile to check out. http://siliconangle.com/blog/2015/0...for-the-enthusiast-and-where-to-buy-supplies/ Among the models included are the famous MakerBot series, the newer LulzBot, and also well known Ultimaker, and other series. There's a multitude of different 3D printers on the market and while most of them use plastic or vinyl filaments (called PLA and ABS) some of them also use photopolymer vats -- one on the list does -- which is messy but a lot more fun to watch. Anyone here in the forums interested in 3D printing?
