Scientists from Korea presented a method for 3D printing bendable devices. It is inexpensive and does not require additional hardware.
The new technology enables more efficient and efficient transfer 3D printing of electronic devices, developed by researchers at the Institute of Science and Technology (DGIST) in Korea. The technique, published in Science Advances, could improve the production of precision devices such as biosensors and wearable devices.
“Our research team was the first to develop instant dry transfer printing technology that can be used on a small or large scale without the need for expensive equipment,” said Seungkyung Heo, one of the study’s lead authors.
This type of printing takes functional elements from one material and applies them to another. It allows the creation of flexible and extensible electronic devices used in a wide variety of fields such as wireless communication systems, wearable health monitors, and flexible electronic displays.
The most common production technology, wet transfer printing, has several drawbacks that limit its application. These include limited accuracy, long processing times, and device displacement or distortion caused by fluid movement during printing. In recent years, alternative methods of dry transfer printing have emerged, but these require special conditions or expensive equipment such as lasers. Therefore, this method is almost never used.
The innovative printing technology developed by DGIST researchers is the most versatile and scalable printing method created to date. It can be used by small research institutions that do not have access to traditional dry transfer printing equipment.
