Scientists Discover a Nature-Inspired Trick for Speedy 3D Printing
Imagine if you could grow a toy, a cup, or even a boat hull the same way a tree grows—by expanding outward! Scientists have invented a brand-new 3D printing technique that does just that. It’s called growth printing, and it’s super fast—way faster than regular 3D printing and even quicker than the fastest-growing bamboo on Earth!
How Does Growth Printing Work?
Instead of slowly adding layers like regular 3D printers do, growth printing works by heating up a special liquid resin. Once the resin is warmed up, it hardens and expands outward—just like tree trunks growing ring by ring! Scientists can pull and shape the resin while it’s hardening to create different designs, similar to how glassblowers shape hot glass.
This method was invented by researchers at the Beckman Institute for Advanced Science and Technology. They wanted to find a way to make 3D printing cheaper, faster, and more energy-efficient. Their idea was inspired by the way trees naturally grow in nature!
What Can This Super-Fast Printer Make?
The scientists tested their method by printing cool objects like:
- A pinecone 🌲
- A raspberry 🍓
- A squash 🎃
- Even a little kiwi bird! 🐦
Right now, this printing technique is best at making rounded, symmetrical shapes. Making sharp corners, like a cube, is tricky—but hey, how many cubes do you see in nature? Scientists are working on ways to make even more complex designs in the future.
Why Is This Important?
Growth printing could change the way we build big things like wind turbine blades, airplane parts, and even boats! Traditional 3D printing is slow and expensive, but this new method is super quick and uses very little energy. That makes it a greener, more Earth-friendly way to create useful things.
Fun 3D Printing Facts!
🖨️ The first 3D printer was invented in 1983 and was about the size of a refrigerator!
🌱 Some scientists are working on 3D printing houses out of natural materials like mud and bamboo!

🔬 There are 3D printers that can print human organs like ears and even heart tissue!
The Future of Growth Printing
Scientists believe this breakthrough could lead to faster, more efficient manufacturing. Who knows? Maybe one day, we’ll be able to print a bike, a car, or even a house just by letting it grow! 🌱🏡
