The first 3D-printed steel bridge looks like it broke off an alien mothership

The plan to 3D-print a bridge in mid-air was always bonkers. How could a technology best known for creating flimsy prototypes and personalized action figures be used for permanent construction projects? Well, the team at MX3D in Amsterdam just answered all of the hard questions and revealed it: the world’s first 3D-printed bridge. It’s made of a completely new type of steel, spans 40 feet, and will be installed early next year in De Wallen, the largest and best-known red-light district in Amsterdam. It also looks utterly otherworldly. Read more at Gizmodo.

Benefits of FPGAs & eFPGA IP in Futureproofing Compute Acceleration

Sponsored by Achronix

In the quest to accelerate and optimize today’s computing challenges such as AI inference, our system designs have to be flexible above all else. At the confluence of speed and flexibility are today’s new FPGAs and e-FPGA IP. In this episode of Chalk Talk, Amelia Dalton chats with Mike Fitton from Achronix about how to design systems to be both fast and future-proof using FPGA and e-FPGA technology.
