3D Systems missed on earnings last night reporting shrinking, worse-than-expected losses. Management says business improved in Q4 despite the loss but forecast continued falling sales in 2025 ...

In this paper, we introduce LiDAR-SPD, a novel approach to defend against adversarial attacks targeting LiDAR-based 3D object detectors. Specifically, a spherical purification unit is designed, which ...

Here, we introduce interference optical projection tomography to visualize and quantify force chains in 3D granular media—the most abundant form of solid matter on Earth and beyond. By combining the ...

The 3D printer design gods were good to us, delivering an upside-down FDM printer and a hack that can automatically swap out heated beds for continuous printing. We look at a drone design that ...
