3D printing has long forced a trade-off between speed, fine detail and the materials you can use. On November 4, 2026, Northwestern Engineering researchers described a method that tries to remove it. Called direct ink additive lithography (DIAL), it was published in Science Advances and announced in a Northwestern Engineering news article.

Laser Lights and Viruses: Novel Additions to Biosensors
New biosensors use suits of light and virus-filled fibers for accurate and timely detection to improve safety.
Researchers funded by the National Science Foundation (NSF) are creating a new biosensor that uses laser light and engineered viruses, created with advanced manufacturing techniques, to more accurately detect the smallest amounts possible of biological molecules in our food, water or blood.
Health tests conducted for pregnancy and blood sugar involve putting a drop of fluid on a t...
