Do engineers hate builders or something?! #howto #construction #homerenovation

Detailed Explanation on Instagram: "Engineers have recreated one of nature’s most precise tools. A mosquito’s proboscis, the ultra-thin needle it uses to pierce skin, inspired a new high precision 3D printing nozzle that can create structures only micrometers wide. The team studied how the proboscis slides smoothly into tissue with minimal force. They then engineered a flexible, layered nozzle that mimics its shape and mechanics, allowing it to print complex microstructures with extraordinary ac
