New 3D Printing technologies being developed in Korea
The introduction of 3D printers was a technological breakthrough.
One of the drawbacks however...is that printer-made products are too fragile and rough in texture to replace conventionally manufactured goods.
To solve this problem, Korean researchers are developing some exciting new technologies.
Cho Sung-min reports.
South Korean researchers are developing new technologies to enhance the capability of 3D printers.
Recently, a team of engineers from the Korea Electrotechnology Research Institute,... developed a method to print three-dimensional circuit devices, using a carbon nanotube ink.
This technology enables printers to manufacture complex nanostructures... in various shapes and configurations that were technically impossible to do so in the past.
"The method will first be used to print electronic equipment with sophisticated components, such as transducers and emitters. In the long term, it will be used to manufacture wearable electronics... including bendable electronic suits."
At another lab in the country,... a research team from the Korea Institute of Science and Technology... has successfully printed a wooden pillar, using natural raw materials.
They used cypress trees that have been ground up into powder,... to print these wooden pillars.
The powder was meticulously arranged and stacked layer-by-layer, to create the final product.
They can be used to build traditional Korean housing known as "hanok"... and the intricate carvings and other details featured in authentic hanok pillars,... can be replicated by the printers.
"It's meaningful that we merged advanced technology with all-natural, eco-friendly materials, to reproduce the pillars in a way that's been embraced for thousands of years."
These new technologies could open up,... all new possibilities for Korea's 3D printing industry... in allowing the use, of a wider range of raw materials... to manufacture products, that were impossible to make through conventional means and methods.
