An Israel-based supplier of 3D printing applied sciences and nano-inks is now delivery a desktop machine to beta prospects that may produce multi-layer circuit boards.
Nano Dimension’s Dragonfly 2020 is a desktop 3D printer that may produce circuit board prototypes and small manufacturing runs, doubtlessly lowering growth time from weeks to hours, in line with Amit Dror, co-founder and CEO of the startup.
The Dragonfly 2020 makes use of an inkjet-like materials deposition methodology adopted by a heat-based curing system to create the printed circuit boards (PCBs), and it has no restrict to the variety of layers past the mechanical peak of the printer’s z axis.
The printer works by first depositing a dialectic insulating materials and a silver-based nano-ink for circuitry on prime of it.
Not one of the nano-inks extruded by the 3D printer begin at room temperature; earlier than they’re desposited on the print platform, they undergo course of known as curing and sintering, which bakes the supplies to eliminate solvents, then they’re melted additional earlier than being extruded, Dror stated.
“The nano silver particles get melted at very low temperatures — one thing like 100 and 200 levels Celsius,” he stated. “As soon as they’re sintered, the nano-ink turns into stable silver. It will not soften once more till the temperature hits 900 Celsius.”
“In reality, to our greatest data, we’re solely firm that may print two kinds of supplies — dialectic and conductive — that may stand up to excessive temperatures with excessive decision,” Dror added.
The Nano Dimension Dragonfly 2020 can print conductive traces which are about 100 microns in width; the machine makes a number of passes to create the width required for one line.
When commercially out there, the 3D printer can have value round $200,000, Dror stated.
Nano Dimension, based in 2012, first unveiled the Dragonfly 2020 on the SolidWorks World convention in January 2016. That very same 12 months, Nano Dimension was added to Gartner’s “Cool Vendors in 3D Printing” report. In that report, Gartner acknowledged the corporate’s printed circuit boards (PCBs) know-how “doubtlessly permits scalable manufacturing of customized merchandise. This places Nano Dimension’s PCB printer on the convergence , mechanical and software program design and manufacturing.”
Gartner added that the PCBs might “have distinctive signatures that make counterfeiting of the merchandise with a customized 3D-printed PCB troublesome if not not possible.”
Nano Dimension, Dror stated, is now working with 10 beta prospects, together with U.S. banks, a healthcare firm, a protection contractor and electronics organizations. Dror was unable to call many of the firms attributable to confidentiality agreements.
The World Printed Circuit Board (PCB) market, which was price $63.5 billion in 2016, is expected to reach about $73.8 billion by 2021, growing at a compound annual progress price three.1% over that point, in line with BCC Analysis.
Usually, PCBs manufacturing is outsourced to 3rd events in Asia. Printing prototypes in-house not solely protects an organization’s mental property, but it surely additionally permits builders to check concepts which may in any other case be too costly, Dror stated.
“It might probably take weeks to get again a prototype. With the ability to create and alter a design and get it up for testing inside a number of hours as an alternative of few weeks is the benefit we provide our customers,” Dror stated.
Nano Dimension shouldn’t be the primary firm to provide a 3D printer for circuit boards.
The Voltera V-One 3D printer, which dispenses conducting and insulating ink to create circuit-completed boards for prototyping, garnered almost 5 occasions its $70,000 crowdsourcing purpose. Subsequent month, the corporate plans to start delivery its 3D printers, which retail for $2,199.
Additionally in 2015, Harvard researchers introduced the creation of a 3D printer that could extrude each thermoplastics and extremely conductive silver inks that enable digital merchandise to be created on one course of.
The printer, sold by Voxel8, had a base value of $eight,999 and noticed a restricted manufacturing run; it’s not out there and the corporate is at the moment growing new, “extra succesful” platform, it stated.
Terry Wohlers, president of 3D printing trade analysis agency Wohlers Associates, stated he has not not too long ago analyzed Nano Dimension’s competitors, however famous there aren’t many rivals and the corporate “presents one thing fascinating and particular” restricted to prototypes and small manufacturing runs.
Within the distant future, Wohlers believes, industrial 3D printers will produce circuits and different electronics that conform to the form of a tool, in addition to the plastic enclosure itself. As we speak, merchandise are designed to accommodate typical printed circuit boards.
“Over time, the marketplace for 3D-printed circuit boards might change into massive, however many issues first should be solved,” Wohlers stated. “Certainly one of them is the printing of a number of supplies, one other is pace, and a 3rd is value, particularly for manufacturing portions.”
