Desktop 3D printer presages the way forward for multi-layer circuit board design

An Israel-based supplier of 3D printing applied sciences and nano-inks is now transport 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 decreasing growth time from weeks to hours, based on 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 top 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 high 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 referred to 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 strong silver. It will not soften once more till the temperature hits 900 Celsius.”

“The truth is, to our greatest data, we’re solely firm that may print two varieties of supplies — dialectic and conductive — that may face up to excessive temperatures with excessive decision,” Dror added.

The Nano Dimension Dragonfly 2020 can print conductive traces which might be about 100 microns in width; the machine makes a number of passes to create the width required for one line.

When commercially accessible, the 3D printer can have price 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 yr, 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 allows 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 may “have distinctive signatures that make counterfeiting of the merchandise with a customized 3D-printed PCB tough if not inconceivable.”

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 corporations on account of confidentiality agreements.

The World Printed Circuit Board (PCB) market, which was value $63.5 billion in 2016, is expected to reach about $73.8 billion by 2021, growing at a compound annual development charge three.1% over that point, based on BCC Analysis.

Usually, PCBs manufacturing is outsourced to 3rd events in Asia. Printing prototypes in-house not solely protects an organization’s mental property, nevertheless it additionally permits builders to check concepts that may in any other case be too costly, Dror stated.

“It will possibly take weeks to get again a prototype. With the ability to create and alter a design and get it up for testing inside just a few hours as an alternative of few weeks is the benefit we provide our customers,” Dror stated.

Nano Dimension is just not the primary firm to supply a 3D printer for circuit boards.

In 2015, Voltera ran a highly successful Kickstarter campaign to fund its desktop circuit board 3D printer.

The Voltera V-One 3D printer, which dispenses conducting and insulating ink to create circuit-completed boards for prototyping, garnered almost 5 instances its $70,000 crowdsourcing purpose. Subsequent month, the corporate plans to start transport 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 permit 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 now not accessible and the corporate is presently creating new, “extra succesful” platform, it stated.

Terry Wohlers, president of 3D printing business analysis agency Wohlers Associates, stated  he has not just lately analyzed Nano Dimension’s competitors, however famous there aren’t many rivals and the corporate “affords one thing attention-grabbing 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. Immediately, merchandise are designed to accommodate typical printed circuit boards.

“Over time, the marketplace for 3D-printed circuit boards may grow to be massive, however many issues first have to be solved,” Wohlers stated. “Considered one of them is the printing of a number of supplies, one other is pace, and a 3rd is price, particularly for manufacturing portions.”
