3 D Printing & Additive Manufacturing

Building a New 3D Material with DNA

In two papers, one released in Nature Materials and a second in ACS Nano, researchers describe a new methodology for fabricating targeted 3D nanoscale structures via self-assembly that can find use in a variety of applications, and they provide a design algorithm for others to follow suit. And it’s all based on the most basic biomolecular building blocks: DNA. Read on to learn more.

Getting Robots to “Bee” have Without a Plan

Bees, ants, and termites don’t need blueprints. They may have queens, but none of these species breed architects or construction managers. Each insect worker, or drone, simply responds to cues like warmth or the presence or absence of building material. Now, researchers at Penn Engineering have developed mathematical rules that allow virtual swarms of tiny robots to do the same. Read on to learn more.
