WASHINGTON — Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials onto paper. They demonstrated the new approach by using it to make three ...

Kaya Keller, a studio assistant at D.R.A.W., works on a hand-made “automatic drawing machine” that spits out drawings upon request based on which button is pushed. This will be showcased at the First ...

The new technique uses a ballpoint pen with conductive ink to draw conductors and mechanical pencils to draw resistors and resistive films. They incorporated this process into a computer-controlled ...
