Printed electronics is an emerging electronic additive manufacturing technology based on the printing principle. Its principle is to use conductive materials such as inkjet, aerosol jet, material extrusion, etc. to transfer conductive and dielectric-igniting materials to the substrate. Electronic devices and systems.
Neotech AMT is one of the companies that provide 3D printed electronics manufacturing technology. The range of 3D printed electronics manufacturing equipment ranges from rapid prototyping to mass production of electronic products. Its 5-axis manufacturing equipment integrates aerosol injection (Aerosol Jet). 3D print head.
Recently, Neotech AMT announced that it will further promote the development of 3D printed electronics manufacturing technology through two new research projects, including 3D printed plastic structures and electronic multi-material composite 3D printing processes, as well as 3D printing ceramics.
Neotech AMT's existing 3D printed electronics manufacturing technology is based on a 5-axis system with integrated Aerosol Jet 3D printheads. Key applications developed by Neotech AMT through this technology include conformal antennas for 3D printed mobile devices, 3D molded interconnect devices, 3D printed circuits and sensors.
Recently, one of the research projects that Neotech AMT participated in was the European Union's PENTA project, which aims to develop a multi-material composite 3D printing manufacturing process for 3D printed polymers and 3D printed electronics. In addition to the manufacturing technology itself, the process will integrate the processes of quality monitoring and online testing.
One of the results of the PENTA project is the fabrication of functionally integrated electrical product prototypes, such as LEDs, automotive adaptive sensor prototypes, through a composite 3D printing manufacturing process.
Another project that Neotech AMT is involved in is the EU Manunet program. This project will focus on ceramic 3D printing technology for the electronics sector. 3D printed ceramic materials are highly resistant to heat and can be used in extreme environments.
Neotech said that these two new projects will further expand its 3D printing technology and promote the application of 3D printing technology in the electronics industry.
The application of 3D printing technology in the electronics industry is still in its early stage. At present, it is mainly used for rapid prototyping of electronic products. The main application of electronic dedicated 3D printers on the market is the rapid prototyping of PCBs. These printer manufacturers provide matching conductive printing. material. However, there are a few applications that have gone beyond prototyping and are moving toward mass production of electronic products such as conformal antennas and sensors. In the long run, 3D printing will reach billions of dollars in the market for electronic parts manufacturing and packaging.
It is understood that in the international market, Voxel8 and Multifab have launched multi-material composite 3D printing electronic equipment, its application range includes PCB rapid prototyping, antenna, structural electronics, ultrasonic sensors and so on. This type of process enables pauses during printing and embedding other components. The fully automated composite 3D printing process developed by the University of Sheffield's Advanced Manufacturing Research Center in collaboration with Boeing has achieved phased results, enabling electronic components to be embedded in 3D printing processes to directly create embedded electronic products, such as A drone with embedded electronic components.
A typical application for ceramic 3D printing in the electronics field is high temperature ceramic sensors. In this regard, GE has taken the lead in applying for a patent, which discloses a method for manufacturing a strain sensor on a turbine component. The ceramic powder of the strain sensor is deposited onto the surface of the blade by an automated 3D printing additive manufacturing process, which may include a thermal barrier coating such as yttria and stabilized zirconia. Completion of strain sensor manufacturing requires coordination between different devices, including aerosol-jet 3D printing devices (eg, Optomec aerosol and lens systems), micro-jets (such as Ohcraft or nScrypt's micro-pen or 3Dn), and MesoScrabe Technologies' plasma spray equipment MesoPlasma.
