At a technical seminar held in Silicon Valley, USA, organized by market research firm IDTechEx, two companies demonstrated the ability to “spit†a small circuit board 3D printer, while other players such as Qualcomm demonstrated Technological advances in placing electronic components on plastic substrates.
James Stasiak, HP's printing technology expert, said: "We see 3D printing as a push for a world with mega-sensors;" he said in a special speech, traditional electronic components and Nai The combination of 3D printed on the new substrate will respond to the demand for low-cost sensors in the future Internet of Things, and manufacturers such as the American company Kateeva can provide a YieldJet inkjet printer suitable for the size of the room. OLED components are produced and DNA printing and other biological materials can be studied.
At the seminar, the Israeli-based startup Nano Dimension's DragonFly 2020 3D printer debuted in the US, which can produce 20 cm (cm) square, height of about 3 mm (mm), stitches. A multilayer circuit board with a width of only 80 micrometers (micron) requires only 3 to 20 hours depending on the number of layers.
Nano Dimension's customers are board users who don't want to wait (usually take weeks to make) and can accept about $50,000 in printer costs; the company plans to be at the International Consumer Electronics Show (CES) next year. It began to pre-sell its 3D printer products and began shipping since the end of next year.

The key to Nano Dimension's 3D printers is silver conductive inks and the company's own insulative inks, using Minolta's 500-nozzle nozzles; like many others targeting the same market, the company is also developing cheaper copper. Conductive inks, but as its co-founder and CEO Amit Dror said, no one in the industry has been able to overcome the problem of allowing copper to oxidize during printing.

HP's Stasiak says companies like Nano Dimension will eventually offer a lower cost and more flexible way to make printed circuit boards than traditional methods; but he also pointed out that one of the challenges of using inkjet is that the current technology is only It can provide femto-liter ink droplets, making the resulting circuit board traces relatively large.
3D printer for making circuit boards by extrusion technology
Another startup, Voxel 8, was born in Harvard Laboratories, USA, and also showed a 3D printer that can make circuit boards. However, the device is not inkjet, but a self-developed one. The toothpaste-like material is formed into an electric circuit board by an extrusion method. Its materials and processes enable Voxel 8's 3D printers to make plastic electronic components as well as conductive components.

Voxel 8 co-founded Michael Bell: "We can make things that traditional printed circuit board (PCB) processes can't make, like 3D hearing aids or plastic antennas." Voxel 8 has so far raised $13 million in investment. Its printer can produce 6 × 6 × 5 inches, 200 micron stitch circuit board, is expected to be shipped before May next year, priced at 9,000 US dollars; the company also said that the future is expected to further stitch Reduced to 1 micron.
3D printers are getting cheaper
Another American manufacturer, Owl Works, showed its 3D printer Morpheus, which can produce 340×190×330mm, 170 micron resolution and 25~200mm height components; the device is expected to start selling next spring at a price of only $500, almost Currently half of similar products on the market. The company's marketing chief, SJ Park, said that the reason for the low price of the product is because of the lower cost ultra-ultraviolet light source and LCD screen to replace the laser and digital light processor used by other printers.

　 Qualcomm Showcases Electronic Components Made of Plastic Substrates
The technology for making electronic components on plastic substrates is also known as surface electronics, and Qualcomm is looking for applications for such components; Stein Lundby, a researcher at the company, said: "We are trying to make this relatively lower-order electronics Components that define or create high-value applications are expected to take advantage of their size advantages over traditional electronic components."
Lundby showcased Qualcomm's prototype EnFucell, a hybrid plastic circuit that combines Bluetooth and accelerometer chips to look like an OK stretch that fits into a golf club to measure the user's swing. . This disposable patch uses printed circuitry and a battery that maintains a race time to transfer the collected data to a smartphone app; the disposable component avoids the need to have a chip built into the club Long-term swing power of golf clubs up to 1500G, which may be difficult to bear.

Plastic LED
Other surface electronic components unveiled on the show floor, including Nth-Degree, showcased the LED embedding in plastic; the company will launch its first product, the LED strip and development tool, priced at $5 per foot. Nth-Degree's products are made with self-developed conductive inks and patented gallium nitride LED technology. In the future, Nth-Degree plans to enter the computer and TV as an ultra-thin backlight.
