A design engineer from GE Additive has come up with a low-cost and simple 3D printed face mask that has already been adopted across the U.S. Navy.

This web app creates a printable fabric pattern for a sew-it-yourself face mask. With a few simple measurements, the mask can be fitted to almost anyone's face: Make your own mask pattern here.

Mask 3D effect has been studied in the past and the main characteristic of it is that it will cause positive focus shift to the semi-dense patterns at pitches of 200 and 300 nm for as much as 20–30 nm ...

In 45nm node and beyond with hyper NA lithography, mask topography effect is not ignorable and mask CD bias impacts printing performance such as MEEF or exposure latitude. In that situation, 3D ...

Here the authors have fabricated quasi 3D structures by the thermal deformation of simple two-dimensional laser-induced patterns.
