What to know about Pixel patterns harness diffraction for faster, more accurate nanoscale 3D printing

Researchers at the George W. Woodruff School of Mechanical Engineering have developed a nanoscale 3D printing method that uses diffraction and pixel patterns to increase both printing speed and accuracy. The technology, published in Nature Communications, has potential applications in biomedical devices, optics, and fusion energy, and is being commercialized through a startup called Stellar Scale Nano Foundation.

What happened

Pixel patterns harness diffraction for faster, more accurate nanoscale 3D printing Gaby Clark Scientific Editor Robert Egan Senior Editor Researchers at the George W.

Why it matters

Woodruff School of Mechanical Engineering have developed a new approach to nanoscale 3D printing that improves both speed and fidelity, overcoming a challenge that has limited the technology's broader use in manufacturing.

Common ground

Their work, led by Sourabh Saha, associate professor and Woodruff Faculty Fellow, and Harnjoo Kim, who conducted the research during his doctoral studies and later as a postdoctoral fellow in Saha's lab, was recently published in the journal Nature…
