Samsung Electronics Using Optomec’s Aerosol Jet 3D Printing to Make Next-Generation Consumer Electronics

New Mexico-based Optomec, which supplies production-grade 3D printing systems for electronics applications and LENS Directed Energy Deposition 3D printers for the manufacturing of metal parts and components, just announced that Samsung Electronics will be using its patented Aerosol Jet technology. This week, it was revealed that Samsung has commissioned one of Optomec’s Aerosol Jet (AJ) 5X 3D printers, which will be put to work in its Printed Electronics Lab for the fabrication of next-generation consumer electronics.

First unveiled back in 2014, the AJ 5X was developed for those customers working to develop electronics like molded interconnect devices (MIDs), sensors, smart phones, and tablets. Many customers use the system to work on more advanced fabrication projects, as it has the ability to print high conductivity inks and dielectric materials in complex shapes on a variety of substrates and 3D surfaces, which makes it possible to shrink electronic devices down.

Optomec’s Aerosol Jet technology accurately and precisely deposits electronic inks through the use of aerodynamic focusing. First, the material is place into an atomizer, which creates a mist of ink-laden droplets that is delivered to the deposition head. There, a sheath gas (usually compressed air or clean, dry Nitrogen) surrounds the aerosol as an annular ring to focus it. Once this gas and the aerosol pass through the profiled nozzle, acceleration occurs and the aerosol is focused into a tight stream of droplets that flow inside the gas, which also insulates the nozzle to prevent any material clogs.

“The resulting high velocity particle stream remains focused during its travel from the nozzle to the substrate over a distance of 2 to 5 mm maintaining feature resolution on non-uniform and 3D substrates,” the Optomec website states. “The system is driven by standard CAD data which is converted to make a vector based tool path. This tool path allows patterning of the ink by driving a 2D or 3D motion control system. Printed features range from 10 microns to millimeters.”

The Optomec AJ 5X system can print features that range from millimeters down to 10 microns, and the 3D printer also supports 5 axes of coordinated motion with its 200 x 300 x 200 mm print envelope. The company has 20 years worth of materials and process research to its name, can help industry customers improve performance and lower product costs, and it also offers the necessary software to go with its Aerosol Jet systems for printed electronics.

The patented Aerosol Jet process is used by many to make things like sensors, RF interconnects, flexible hybrid electronics, wire replacement bonds for IC packaging, and multi-layer, miniature circuits; the technology can even be used to 3D print antennas directly onto electronics enclosures.

Nano Dimension Continues its Growth in the 3D Printing Industry

Israeli PCB print leader Nano Dimension showed off its DragonFly 2020 Pro 3D printer at a US event for the first time while attending RAPID + TCT in Texas last year. Not too long ago, I finally had the opportunity to see the machine for myself while attending this year’s RAPID in Detroit, Michigan.

The industrial PCB printer was the first thing I saw at the booth – it’s hard to miss, being much taller than its desktop predecessor. The system stands on the floor and offers a larger footprint, though it has the same 20 x 20 cm print area as the original DragonFly 2020, which officially ended its beta program in the summer of 2017. Tim Sheehan, the VP of Global Sales and Customer Care for Nano Dimension USA Inc., came over to greet me, and we sat down to chat.

Sheehan used the example of an electrical engineer looking to make a prototype board, noting that everything involved in the process – from finding a business to make the prototype, filling out and getting a purchase order approved, having the prototype made and getting it shipped to you – can cost thousands of dollars and take months to complete.

“That’s the standard process that people deal with today,” he said.

“Now, along comes someone who says, what if I could increase your productivity and reduce your cycle time…that’s giving you a return on investment that’s going to help.”

Then we walked over to the DragonFly 2020 Pro so I could get a closer look. Sheehan explained that a dielectric ink (DI) and a conductive ink are both cured at almost the same time within the system.

“It takes sophisticated software to calculate the algorithm to make sure that what you want to be a feature on that board…something as simple as a hole…it places the hole each time at the appropriate place.

“The board is being printed on a chuck, and that chuck is a heating element and a holding element, so it’s holding what’s being printed.”

The chuck moves back and forth, while the ink is being distributed exactly where it’s supposed to go. Nano Dimension uses a free SOLIDWORKS add-in which, according to its website, “creates a design environment optimized for 3D printing multi-material electronics.”

“So all of this can allow that electrical engineer not to take all that time – that two days for approval, a week to get all the signatures, three to five weeks for the board to show back up, ordering of components – all that time. You can now have a board printed overnight.”

Sheehan told me that, as an engineer, the first design you come up with is never the best. The DragonFly 2020 Pro really helps to speed up the design process, so if you need to make changes and iterations, you’re not wasting everyone’s time. He then showed me some examples of what the PCB printer is capable of, including a 12-layer PCB (below) that took a total of 20 hours to print.


“Time is only determined by the amount of silver we want to put down,” he explained.

“No one else in here can do this. The only way this is being done is the old-fashioned, traditional way, which is one layer at a time is created.”

He also showed me a PCB with an indentation on one end where a battery will sit, which also features a circuit that’s on multiple layers.

Next, Sheehan brought out a sample that demonstrates a helical conductive coil – created in 180 extremely fine turns – that’s embedded in the company’s dielectric ink; this shows Nano Dimension’s ability to create non-planar conductors, and embed them in a structure, in a single process. This can be used in applications such as charging cell phones or as a solenoid, which acts like a magnet when carrying electric current.

“Solenoids generally grab something locked…unlock the solenoid, door opens,” he explained.

“I have children, I’m not home, they come home from school, the door opens, the signal gets sent, I know they’re home. This is the whole IoT, right? Related to electronics.

“So how this all plays through for us is I’m helping you increase productivity.”

I asked Sheehan if anything new was happening with Nano Dimension that he could tell me about, and he said that the company had recently begun a European expansion, in addition to completing its partner development in North America.

“We’ve signed on national and global leaders in additive manufacturing.”

He listed some of these, including additive solutions and SOLIDWORKS software reseller Go Engineer, CATI, and Fisher Unitech, which is the largest Stratasys reseller in the world.

“So, what else is new for us? A lot of what we call application development sharing – we’re introducing how we can help people side mount components, how we can help people create three-dimensional applications, like the inductive coil,” Sheehan explained. “That’s just a few of the many different, what we call ‘feature applications,’ we’re introducing to help people stretch their minds around what else you can do with the DragonFly.”

Nano Dimension has been listening to its customers, and until this point, the company’s “addressable market” has been R&D with major research institutes. But now, the US Department of Defense is one of the top markets it’s addressing, after becoming a certified DoD vendor last June.

“They are the biggest single organization buying from us today,” Sheehan said, noting that Tier 1 suppliers are also purchasing DragonFly printers. “There are different Army, Navy, Air Force branches buying this system, doing things that we don’t even really know because it’s not for us to know…we’re probably not allowed to know.

“So that’s exciting because when you bring a product to market, you want to know who to address in the market, you want to make sure you go target that. But what’s important is we gather the information from them, and then come back and do the appropriate things for the future of the product. So that’s been successful for us.”

Before I left, Sheehan presented me with my very own 3D PCB, which now sits on my desk next to a myriad of other prints I’ve made or been given. I was excited to receive the PCB, not only because it’s a good physical reminder of what 3D printing is capable of, but also, as I said to Sheehan, who doesn’t like to be handed a little white box?

European Innovation Hub and Test Bed to Focus on Developing and Implementing 3D Printed Electronics

More and more, we are using special industrial 3D printers, with inkjet and aerosol jet technology, to embed conductive components within our intelligent products in what we call 3D printed electronics. Items like ECG electrodes and contactless payment cards use these embedded components to perform wireless activities and readings, like measuring the frequency of a person’s heart beats and paying for something at the store. The technology makes it possible to 3D print conductive circuits on nearly any surface imaginable, and the market for it is estimated at $32 billion outside Europe alone. Now, the continent is working to play catch-up.

In a move to increase Europe’s competitiveness in this field, and further prepare for Industry 4.0, the European Union’s Horizon 2020 has granted €10.6 million in funding to a new European innovation hub, led by the Danish Technological Institute (DTI), that will focus on 3D printed electronics.

“Printed electronics opens up a whole world of new opportunities, as complex constructions can be embedded just like using 3D printing, at prices able to compete with mass-produced goods,” said Zachary James Davis, DTI’s Project Coordinator for the hub. “Quite simply because electronics can be produced from CAD drawings and printed on flexible materials, as already used in architecture and 3D print.”

DTI researchers have been working with 3D printed electronics since 2016. This work, coupled with its efforts in encouraging the adoption of 3D printing, is what makes the university the perfect leader for the new hub as it works to help Europe’s manufacturing industry gain a strong position. Together with 16 RTOs and businesses, such as Fraunhofer, Eindhoven University of Technology, RISE, and Axia, DTI will develop an open innovation test bed, or LEE-BED, which will function as the hub and focus on 3D printed electronics.

Enterprises that apply to join LEE-BED will have their businesses cases evaluated first. If they are selected to participate, they will receive access to RTOs which most closely match their personal requirements. In addition, the chosen enterprises will also have access to expertise and equipment from designated RTOs in order to support their own 3D printing electronics development efforts, with no financial risk, all the way from the prototyping phase up to pilot production and full-scale manufacturing.

Davis explained, “All the partners in LEE BED will provide their various skills and facilities within printed electronics to enterprises that want to integrate and embed electronics into their products.

“Enterprises will be able to prove the viability of new technologies without major investment and financial risk during the all-important initial phase. We have already started working with jewellery giant Swarovski, looking into the idea of intelligent light in their crystals that can be integrated with clothing and home interiors.”

In addition to Swarovski, LEE-BED also has three other industrial cases with European companies: Acciona, Grafietic, and Maier.

LEE-BED is made up of three phases:

  1. Technological & economic modeling, including lifecycle analysis, patent research and safety/legislation audit
  2. The pilot project using current, and upgraded, pilot lines for nanomaterials, nano-enabled formulations, and 2D/3D printing of components
  3. Knowledge transfer, to include evaluation of intellectual property rights (IPR) and patents, investment possibilities, and standards/safety screening

The purpose of LEE-BED is to spread awareness about 3D printed electronics, and develop and implement them across Europe in order to “break down barriers” for the technology to be used. The goal is to keep the European manufacturing industry in the EU, as opposed to outsourcing high-tech projects elsewhere.
