We watched in awe as new materials and techniques emerged from unexpected places, considered a future where organs are replaceable with 3D printing, and envisioned a taller turbine, all this week in 3D printing.<\/p>\n
In techniques and materials this week, MIT unveiled a printing technique that, by melting the plastic much more quickly, results in what can only be described as FDM 3D printing on speed (view it in action below, and learn more at TechCrunch<\/a>), researchers from the U.K.\u2019s University of Nottingham figured out how to print working circuit boards using UV light (Digital Trends has the full story<\/a>), and West Africa’s WoeLab<\/a> has created a 3D printer made of e-waste, turning a massive pollution problem into an economic opportunity (via CNN<\/a>).<\/p>\n
