I don't know what's being added or what it's being added to but you can get certified by MIT https://3dprintingindustry.com/news/mits-online-additive-manufacturing-course-returns-138110/
Thanks for posting this. Additive can mean many things like the type of plastic or metal or the use of specialized plastic like antimicrobial for use in medical or sanitary areas. Many properties can be added to the plastics for 3D printing that can enhance the rigidity and expand the use of the application, also with the onset of 3D printing in metal is a game changer. In my business, If I wanted a part machined using a plastic, it would cost me $350 and 2 weeks going to an outside vendor, but 3D printing allows me to it in my building in 6 hours for $11 worth of material.
3D printing is a true miracle. When a Norman Baron wanted a castle, it would take years - and bags and bags of gold coins. And a License to Crenellate. Now along comes a guy who 3D prints the whole freakin' thing - in concrete! http://www.totalkustom.com/3d-castle-completed.html
Johann, Thanks for the post. It never occurred to me that concrete could be used in a 3D Printing application. Good article. Michael
