This efficiency challenge is caused by diffuser plates, sometimes called showerheads, used during semiconductor processing.

Build surfaces matter more than people think. Here are the 3D printer beds I prefer, the lessons I learned the hard way, and how to choose the right surface for your filament and projects. Venezuela ...

Abstract: At present, deep learning has been widely adopted in medical image processing. However, the current deep neural networks depend on a large number of labeled training data, but medical images ...

Editor's note: Originally published in December 2021. Updated December 2025. It’s underfoot everywhere. Yet in Armstrong Flooring’s new headquarters, pattern 5352 hangs prominently on the wall. Other ...

Abstract: This paper presents a novel Fresnel Zone Plate Lens (FZPL) using perforated 3D printing material at 60 GHz (λ 0 = 5.45 mm). A gradient refractive index condition is controlled using the ...
