From prosthetic body parts to foetus of a baby… and from printed food to selfies, 3d printing is making its presence felt in every aspect of our lives. And what’s more is; we have welcomed this humongous transformation with open arms. Need a house? Print it. Robot? Print it. Ship? Print it. Phew!
Researchers crack the code
3D printing has already been used to create electronic objects like batteries and antennas. However, it seemed that it is going to be difficult to print LEDs and semi-conductors. It was because their printing asked for a different technology which would be unique and make them performance worthy. But now, those qualms have been left behind by a team of researchers in Princeton.
Making of LED and semi-conductors
The brilliant team of researchers have discovered a way of 3d printing quantum dot LEDs and semiconductors as a result with the help of a 3D printer. The question is, how? Well, they chose printable electrodes, semi-conductors as well as polymers which were dissolved in solvents so that they are not damaged during the printing process. Thereafter, they used the design software to print the materials by using weaving different patterns. As a result, a small LED is obtained which can be printed on the objects having different surface textures.
Plethora of utilities
According to the scientists, the technology can be used to create contact lenses having built-in displays and implants that make use of lights to stimulate the nerves. As the technology will work with other semi-conductors, it can be used in transistors, solar cells as well as other electronics. Now this, wasn’t possible before. However, the 3d printing resolution as well as the performance of these semi-conductors have to be enhanced.
This is an amazing concept which will revolutionize the usage of gadgets and other electronic equipments. For more updates on the magic of 3D printing, keep reading!
