Prasad Murugesu Posted over 1 year ago What potential does 3D printing have for developing economies? Brendan, I have given it some thought. I may have to retract my statement of large scale manufacture of firearms using 3D printing, but the possibility still itches at the back of my mind because a few have achieved it. I apologise for being such a pessimist. I sincerely wish a laid back industry such 3D printing takes a big leap forward. 3D printing has never been an option, accessible or even know to the common man, such technology will not only be technically helpful but also be an inspiration to others. Hope a see an organization revolutionize 3D printing, much like Xerox did to photocopying. Heck I would buy one for myself if it becomes cost effective, it's an engineer's dream. A technical issue would be sort out the printing methods best suited for on-site application and the materials/resin used in printing, can they be more economical and meet all the requirements? Example; when installing pipes, sometimes fittings like elbows and tees are of inferior quality or the required size is not manufactured by the manufacturer. Should 3D printing (printer and materials) be a worthwhile investment, the contractor/fitter can print the required parts in advance and assemble with ease. With that comes the problem of designing the parts and CAD literacy, both can be solved by a web-site or app which provides access to ready to print part designs.
