Apple's shift to 3D-printed titanium marks a turning point, not just for wearables, but for how material innovation becomes the foundation for meaningful design change. Every Apple Watch Ultra 3 and titanium Series 11 case now emerges from additive manufacturing using 100 percent recycled aerospace-grade titanium powder. The process cuts raw material consumption in half and saves over 400 metric tons this year alone.
Sure, concrete guitars do exist in the novelty space (they aren't a new idea), but they're typically solid slabs that weigh somewhere between 80 and 90 pounds, which makes them less "playable instrument" and more "sculptural middle finger to ergonomics." What these two pulled off is different. They engineered a semi-hollow body with 3/8 inch concrete walls, kept the whole thing under 20 pounds (19.8 to be exact), and somehow nailed the intonation without any adjustments.
Part 2 of the TED Radio Hour episode "The skin we're in" Anna Maria Coclite is developing artificial skin, even more sensitive than our own. For burn victims and beyond, this "smart skin" has the potential to restore sensation to our body's largest organ. About Anna Maria Coclite Anna Maria Coclite is a professor in the Department of Physics, University of Bari Aldo Moro, in Italy.
Stainless steel 1.4542, known for its exceptional strength and moderate corrosion resistance, stands out due to its capability of being heat-treated for varying strength levels without significant distortion.
