There is no need for heating and lighting. With the advent of 3D printing ink, can circuits be recycled?

[ITBEAR] News on August 11th. Recently, a breakthrough 3D printing technology was successfully developed by a scientific research team from the United States and South Korea. This technology can create easily recycled products without heating, light or relying on toxic chemicals. circuits and other structures. This innovative achievement has been published in an authoritative scientific journal and has received strong support from the National Science Foundation of the United States and the National Research Foundation of Korea.

1. Environmentally Friendly 3D Printing Technology

Traditional 3D printing technology relies on high temperature, pressure or light to solidify materials. But a new technology uses poly-N-isopropylacrylamide (PNIPAM), a nontoxic polymer widely used in drug delivery systems. This technique simply cures by placing it in salt water at room temperature.

2. Easy Curing and Recycling

Utilizing a commercial medical-grade 3D printer, PNIPAM polymer is extruded and pumped directly into a mixture of calcium chloride and water. The material quickly solidifies into fine structures and becomes electrically conductive. Recycling of the material is also simple, just dissolve it in water and then evaporate the water.

3. Environmentally friendly properties

The method is performed under ambient conditions and does not require special equipment or toxic chemicals. Because PNIPAM is easily restored to its original state, structures made with PNIPAM are particularly suitable for use in disposable electronics, robotic components, and prototype manufacturing.

4. Environmental significance

This technology provides a simple and environmentally friendly recycling method, helping to solve the increasingly serious electronic waste problem. -->
