At a technical seminar held in Shibuya, USA, held by market research institute IDTechEx, two companies demonstrated that they could “spit†a small circuit board 3D printer, while other players such as Qualcomm demonstrated Technological advances in placing electronic components on plastic substrates. "We're seeing 3D printing as a push for a world with megasensors," said James Stasiak, a print technologist at Hewlett-Packard (HP). He said in a special speech that traditional electronic components and Nai The combination of 3D printed materials on new substrates will respond to the demand for low-cost sensors in the future of the Internet of Things, and manufacturers such as the US company Kateeva can provide a YieldJet inkjet printer suitable for room size. 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 those who don't want to wait (usually take weeks to make) and can accept the cost of a printer for about $50,000. The company plans to go to 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. Nano Dimension's 3D printer produces a compact, compact board Nano Dimension's 3D printers are key to 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. Amit Dror, co-founder and CEO of Israeli startup Nano Dimension, unveiled with the company's 3D printer 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 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 at the Harvard lab in the United States. It 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 and the company's 3D printer 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, the price is only 500 US dollars, 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 that it uses a lower cost ultra-ultraviolet light source and a liquid crystal screen to replace the laser and digital light processors used by other printers. Owl Works marketing long SJ Park showcases its low-cost 3D printer Morpheus 　 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 stretcher 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. Qualcomm researcher Stein Lundby demonstrates prototypes of its plastic electronic components Qualcomm developed EnFucell components can be combined with golf clubs Plastic LED Other surface electronic components unveiled on the show floor, including Nth-Degree's showcase of embedding LEDs into plastics; 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. Nth-Degree shows the solution to embed LEDs in plastic VTT Technical Research Centre, a Finnish research institute, demonstrated the technology of using a smart phone to transmit power through NFC to illuminate eight LEDs on a printed circuit board. This technology for mounting unpackaged small LEDs on printed circuit boards is Developed by an organization's third-party partner. VTT Technical Research Centre demonstrates the use of smart phones to transmit power through NFC and illuminate 8 LEDs on printed circuit boards In addition, VTT also demonstrated the combination of plastic substrates and LEDs. This technology has been independently a company called Flexbright; the startup is currently testing prototypes and claims to have some potential customers.
