Tooth be told, you might feel lock–key to read this Week in 3D printing recap — it’s electrifyingly good.
Key Developments
Swiss company UrbanAlps has created a key that seems to be impossible to forge, PSFK reports. While replicating keys has become rather effortless with 3D scanning and 3D printing (one more thing to worry about!) this new key uses 3D printing technology to protect you. The 3D printed lock’s titanium teeth are hidden under a pair of narrow ledges, making it impossible to scan—and way more secure than a traditional lock and key.
Brace Yourself
Business Insider pointed to a college student named Amos Dudley who spent only $60 to make a series of 3D printed plastic aligners — which straightened out his smile in less than four months.
As someone who went the traditional orthodontist route (twice), I’m feeling kind of spicy about this story.
Circuit Training

Nano Dimension, an Israeli company, has started shipping out 3D printers that can print multilayer circuit boards, writes ComputerWorld. Nano Dimension’s Dragonfly 2020 prints in two materials: one insulating, the other conductive, and both able to withstand high temperatures with high resolution.
