3D Printing in Electronics Industry

01-3D Printing in Electronics Industry-pcb 3d printer

In order to achieve miniaturization, low energy consumption and intelligent performance, the electronic devices require suitable mechanical, geometric and optical functions. Thanks to increasingly evolving technologies, the development of designs and completed goods has to shift. Throughout the manufacture of electrical instruments, the traditional approach is to mask and etch sacrificial products using subtractive techniques. Additive Manufacturing decreases waste materials, electricity usage, time and phases of production. 3D printing is used to bypass electronic system mounting and assembly phases. The additive manufacturing method deposits material in a layer by layer regulated process which allows the complex geometries and dimension to be manufactured. Therefore, 3D alignment of core components allows better performance. Additive Manufacturing promotes the manufacture of tiny parts which would otherwise be challenging to achieve through conventional methods. For thin films, inductors, solar cells, and many others, Additive Manufacturing has developed a configuration. Inkjet and direct writing of conductive inks are the most popular 3D printing methods for electronics.

Quantum Dot Display

A Quantum Dot (QD) light emitting diode (LED), with green and orange-red light emitters combined in a silicone matrix, has been printed by Jennifer Lewis and colleagues in complete 3D. The imprinted tool displays the best-processed QD-LEP output 10-100 times, but may theoretically be improved with a transport layer of electron. Inkjet printing was combined with 2-(2-butoxy ethoxy) ethanol to prepare a copper nanoparticle that was stabilised by polyvinyl pyrrolidine. The pigment was removed and sintered onto a polyimide at 200 ° C. The ready-to-use electronic system has developed low resistivity of 3.6 μ Ω cm and 2.2 times the copper resistivity.

Bionic Ear

Using an 3D inkjet printer, bionic ears were developed. The bio-compounds were made up of cell-cultivated alginate and hydrogel chondrocytes matrix and conductive silicone and silver nanoparticle polymer. The 3D printed ears display increased auditory sensing to allow the ear to listen to stereo music. It demonstrates that biotechnology and electronics can be paired with modern technologies.

CUBESAT 3D Printing

3D printing CubeSat has been developed by students from the University of Northwest Nazaren and Caldwell High School. The CubeSat was launched in 2013 as part of a NASA mission on board the Delta II launcher. It contains miniaturized electronics and sensors and is designed to gather in real time information on the impact of harsh spatial environments (oxygen, UV, radiation , temperature and collisions). Acrylonitrile butadiene styrene (ABS), Polylactic acid (PLA), Acrylic, and polyetherimide/ polycarbonate (PEI / PC ULTEM) for polymeric materials were used in construction of the CubeSat.

Future 3D Printing Electronics

Potential electronic innovation and software development will take advantage of low-cost, modular architecture and fast-paced manufacturing methods for the production and test of innovative technologies via 3D printers. Printing circuit boards for instance would have superior precision and flexibility, with significant cost cuts, environmental benefits, speedier rates of output and improved design capabilities. Adaptive 3D printing, utilizing a closed-loop system that incorporates real-time feedback control and DIW of usable content, is an innovative development area to create devices on complicated geometries. This 3D printing approach will contribute to different types of smart manufacturing technology for wearable devices directly imprinted in human skin. Throughout the wearable smart technology sector, biology and biomedical science, the development and application of innovative medical therapies, novel opportunities will arise.
