Nanoink and printing technologies could enable electronics repairs, production in space

An Iowa State University engineer floats in the air while other researchers hang tight to a metal frame surrounding and supporting their special printer. It's not the usual photo you see in a research paper. Tests aboard microgravity flights aren't your typical materials experiments, either.

The flight path to these experiments began when a research team led by Iowa State's Shan Jiang, an associate professor of materials science and engineering, and Hantang Qin, formerly of Iowa State who's now an assistant professor of industrial and systems engineering at the University of Wisconsin-Madison, wondered if their ink and printer technologies would work in the zero gravity of space.

The ink features silver nanoparticles synthesized with biobased polymers. After heat treatment, the ink can conduct electricity and can therefore print electric circuits. The printer uses electrohydrodynamic printing, or 3D printing that jets ink under an electric field at resolutions of millionths of a meter. The electric field could eliminate the need for gravity to help deposit ink.

If the technologies work together in zero gravity, astronauts could use them to make electric circuits for spacecraft or equipment repairs. And astronauts might manufacture high-value electronic components in the special, zero-gravity environment of space.

NASA wondered if it would work, too.

Diving into microgravity

Researchers bolted the printer to the floor of a jet and prepared for a "roller coaster, basically," Jiang said.

The NASA plane would continuously climb and dive, going in cycles from about 24,000 feet over Florida to 32,000 feet, then back to 24,000. The dive phase produced about 10 seconds of pure zero gravity.

"It was exciting and new," Jiang said.

Motion sickness was a problem for some. Others enjoyed the thrill of it. Jiang felt "frozen" the first time he experienced microgravity. "I was blank."

But that didn't last. "There was so much time and investment in this project. We wanted to achieve good results."

But printing for a few seconds at a time on a microgravity flight "is a very challenging experiment," Jiang said. "It's so easy on the ground where everything is stable. But if anything gets loose during the flight, you lose your printing."

The first microgravity flight was a good example. The printer wasn't adequately secured against the plane's shakes and vibrations.

"These are very intense experiments that require a lot of teamwork and preparation," Jiang said.

So, the team went back to work, made some changes, made more test flights and produced better results.

"This proof-of-concept microgravity experiment proves the unique capability of (electrohydrodynamic) printing under zero-gravity conditions and opens a new venue for future on-demand manufacturing in space," the researchers wrote in a paper published in Applied Materials & Interfaces.

Making a new nanoink

The key innovation by Jiang's research group was developing a new laboratory method to synthesize the ink with its silver nanoparticles.

"This is a new combination of materials and so we needed a new recipe to make the ink," Jiang said.

Both programs "strive to support innovative and leading research in Iowa," said Sara Nelson, director of the programs and an Iowa State adjunct assistant professor of aerospace engineering. "We are thrilled to have supported Dr. Jiang's research. His work has helped to build Iowa's research infrastructure and is an important part of NASA's strategic mission."

The project also makes use of an abundant Iowa resource, plant biomass.

The ink includes a biobased polymer called 2-hydroxyethyl cellulose, which is typically used as a thickening agent. But it is also a cost-effective, biocompatible, versatile and stable material for the inks necessary for high-resolution ink jet printing under an electric field.

"There is a lot of biomass in Iowa," Jiang said. "So, we're always trying to use these biobased molecules. They make a wonderful polymer that does all the tricks for us."

Jiang called that "the biggest surprise of this research. We didn't know that before. Now we know what we can do with these biobased polymers."

The Iowa State University Research Foundation has filed a patent on the new nanoink and the technology is currently available for licensing.

"This success is really just the beginning," Jiang said. "As humanity ventures deeper into space, the need for on-demand manufacturing of electronics in orbit is no longer science fiction; it is a necessity."

Next up for the researchers could be the development of 3D space printing for other electronic components such as semiconductors.

After all, Jiang said, "You can't just make one component and assemble an electronic device."

Casey Wolfe is developing and producing the next generation payload adapter for NASA’s SLS (Space Launch System) super-heavy lift rocket. The adapter is made with some of the world’s most advanced composite manufacturing techniques.NASA/Sam Lott While precision, perseverance, and engineering are necessary skills in building a Moon rocket, Casey Wolfe knows that one of the most important aspects for the job is teamwork. “Engineering is vital, but to get this type of work done, you need to take care of the human element,” said Wolfe, the assistant branch chief of the advanced manufacturing branch in the Materials and Processes Laboratory at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Together with her team, Wolfe is developing and producing the next generation payload adapter for NASA’s SLS (Space Launch System) super-heavy lift rocket. The adapter is made with some of the world’s most advanced composite manufacturing techniques. Wolfe’s work integrates the technical day-to-day operations and personnel management of the composites manufacturing team and additive manufacturing team, balancing production of SLS hardware with the creation of new engines using the latest manufacturing technologies.  “A lot of my day to day is in managing our two teams, making connections, building relationships, and making sure people feel supported,” Wolfe explains. “I conduct individual tag ups with each team member so we can be proactive about anticipating and addressing problems.” Wolfe grew up in Huntsville, a place known as the “Rocket City,” but it wasn’t until she visited a job fair while studying at Auburn University for a polymer and fiber engineering degree that she began to consider a career at NASA Marshall. Wolfe applied for and was selected to be a NASA intern through the Pathways Program, working in the non-metallic materials branch of the Materials and Processes Laboratory. Wolfe supported a coating system for electrostatic discharge on the first uncrewed test flight of the Orion spacecraft. Launching December 5, 2014, Orion traveled to an altitude of 3,600 miles, orbited Earth twice, and splashed down in the Pacific Ocean. It was during her internship that Wolfe realized how inspirational it felt to be treated like a vital part of a team: “The SLS program gave everyone permission to sign the hardware, even me – even though I was just an intern,” says Wolfe. “It was impactful to me, knowing that something I had worked on had my name on it and went to space.”  Since being hired by NASA, Wolfe’s work has supported development of the Orion stage adapter diaphragms for Artemis II and Artemis III, and the payload adapters for Artemis IV and beyond. The first three Artemis flights use the SLS Block 1 rocket variant, which can send more than 27 metric tons (59,500 pounds) to the Moon in a single launch. Beginning with Artemis IV, the SLS Block 1B variant will use the new, more powerful exploration upper stage to enable more ambitious missions to deep space, with the cone-shaped payload adapter situated atop the rocket’s exploration upper stage. The new variant will be capable of launching more than 38 metric tons (84,000 pounds) to the Moon in a single launch. “While the engineering development unit of the payload adapter is undergoing large-scale testing, our team is working on the production of the qualification article, which will also be tested,” Wolfe says. “Flight components should be starting fabrication in the next six months.” When Wolfe isn’t working, she enjoys hiking, gardening, and hanging out with her dogs and large family. Recently, she signed another piece of SLS hardware headed to space: the Orion stage adapter for the second Artemis mission. With as many responsibilities as Wolfe juggles, it’s easy to lose sight of her work’s impact. “I work in the lab around the hardware all the time, and in many ways, it can become very rote,” she says. But Wolfe won’t forget what she saw one evening when she worked late: “Everybody was gone, and as I walked past the launch vehicle stage adapter, there were two security guards taking pictures of each other in front of it. It was one of those things that made me step back and reflect on what my team accomplishes every day: making history happen.” NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

Scientists 3D Print Self-Heating Microfluidic Devices - Technology Org

The one-step fabrication process rapidly produces miniature chemical reactors that could be used to detect diseases or analyze substances.

MIT researchers have used 3D printing to produce self-heating microfluidic devices, demonstrating a technique which could someday be used to rapidly create cheap, yet accurate, tools to detect a host of diseases.

MIT researchers developed a fabrication process to produce self-heating microfluidic devices in one step using a multi-material 3D printer. Pictured is an example of one of the devices. Illustration by the researchers / MIT

Microfluidics, miniaturized machines that manipulate fluids and facilitate chemical reactions, can be used to detect disease in tiny samples of blood or fluids. At-home test kits for Covid-19, for example, incorporate a simple type of microfluidic.

But many microfluidic applications require chemical reactions that must be performed at specific temperatures.

These more complex microfluidic devices, which are typically manufactured in a clean room, are outfitted with heating elements made from gold or platinum using a complicated and expensive fabrication process that is difficult to scale up.

Instead, the MIT team used multimaterial 3D printing to create self-heating microfluidic devices with built-in heating elements, through a single, inexpensive manufacturing process. They generated devices that can heat fluid to a specific temperature as it flows through microscopic channels inside the tiny machine.

The self-heating microfluidic devices, such as the one shown, can be made rapidly and cheaply in large numbers, and could someday help clinicians in remote parts of the world detect diseases without the need for expensive lab equipment. Credits: Courtesy of the researchers / MIT

Their technique is customizable, so an engineer could create a microfluidic that heats fluid to a certain temperature or given heating profile within a specific area of the device. The low-cost fabrication process requires about $2 of materials to generate a ready-to-use microfluidic.

The process could be especially useful in creating self-heating microfluidics for remote regions of developing countries where clinicians may not have access to the expensive lab equipment required for many diagnostic procedures.

“Clean rooms in particular, where you would usually make these devices, are incredibly expensive to build and to run. But we can make very capable self-heating microfluidic devices using additive manufacturing, and they can be made a lot faster and cheaper than with these traditional methods. This is really a way to democratize this technology,” says Luis Fernando Velásquez-García, a principal scientist in MIT’s Microsystems Technology Laboratories (MTL) and senior author of a paper describing the fabrication technique.

He is joined on the paper by lead author Jorge Cañada Pérez-Sala, an electrical engineering and computer science graduate student. The research will be presented at the PowerMEMS Conference this month.

An insulator becomes conductive

This new fabrication process utilizes a technique called multimaterial extrusion 3D printing, in which several materials can be squirted through the printer’s many nozzles to build a device layer by layer. The process is monolithic, which means the entire device can be produced in one step on the 3D printer, without the need for any post-assembly.

To create self-heating microfluidics, the researchers used two materials — a biodegradable polymer known as polylactic acid (PLA) that is commonly used in 3D printing, and a modified version of PLA.

The modified PLA has mixed copper nanoparticles into the polymer, which converts this insulating material into an electrical conductor, Velásquez-García explains. When electrical current is fed into a resistor composed of this copper-doped PLA, energy is dissipated as heat.

“It is amazing when you think about it because the PLA material is a dielectric, but when you put in these nanoparticle impurities, it completely changes the physical properties. This is something we don’t fully understand yet, but it happens and it is repeatable,” he says.

Using a multimaterial 3D printer, the researchers fabricate a heating resistor from the copper-doped PLA and then print the microfluidic device, with microscopic channels through which fluid can flow, directly on top in one printing step. Because the components are made from the same base material, they have similar printing temperatures and are compatible.

Heat dissipated from the resistor will warm fluid flowing through the channels in the microfluidic.

In addition to the resistor and microfluidic, they use the printer to add a thin, continuous layer of PLA that is sandwiched between them. It is especially challenging to manufacture this layer because it must be thin enough so heat can transfer from the resistor to the microfluidic, but not so thin that fluid could leak into the resistor.

The resulting machine is about the size of a U.S. quarter and can be produced in a matter of minutes. Channels about 500 micrometers wide and 400 micrometers tall are threaded through the microfluidic to carry fluid and facilitate chemical reactions.

Importantly, the PLA material is translucent, so fluid in the device remains visible. Many processes rely on visualization or the use of light to infer what is happening during chemical reactions, Velásquez-García explains.

Customizable chemical reactors

The researchers used this one-step manufacturing process to generate a prototype that could heat fluid by 4 degrees Celsius as it flowed between the input and the output. This customizable technique could enable them to make devices which would heat fluids in certain patterns or along specific gradients.

“You can use these two materials to create chemical reactors that do exactly what you want. We can set up a particular heating profile while still having all the capabilities of the microfluidic,” he says.

However, one limitation comes from the fact that PLA can only be heated to about 50 degrees Celsius before it starts to degrade. Many chemical reactions, such as those used for polymerase chain reaction (PCR) tests, require temperatures of 90 degrees or higher. And to precisely control the temperature of the device, researchers would need to integrate a third material that enables temperature sensing.

In addition to tackling these limitations in future work, Velásquez-García wants to print magnets directly into the microfluidic device. These magnets could enable chemical reactions that require particles to be sorted or aligned.

At the same time, he and his colleagues are exploring the use of other materials that could reach higher temperatures. They are also studying PLA to better understand why it becomes conductive when certain impurities are added to the polymer.

“If we can understand the mechanism that is related to the electrical conductivity of PLA, that would greatly enhance the capability of these devices, but it is going to be a lot harder to solve than some other engineering problems,” he adds.

“In Japanese culture, it’s often said that beauty lies in simplicity. This sentiment is echoed by the work of Cañada and Velasquez-Garcia. Their proposed monolithically 3D-printed microfluidic systems embody simplicity and beauty, offering a wide array of potential derivations and applications that we foresee in the future,” says Norihisa Miki, a professor of mechanical engineering at Keio University in Tokyo, who was not involved with this work.

“Being able to directly print microfluidic chips with fluidic channels and electrical features at the same time opens up very exiting applications when processing biological samples, such as to amplify biomarkers or to actuate and mix liquids. Also, due to the fact that PLA degrades over time, one can even think of implantable applications where the chips dissolve and resorb over time,” adds Niclas Roxhed, an associate professor at Sweden’s KTH Royal Institute of Technology, who was not involved with this study.

Film industry and Production design

"Avatar The Way of Water" By James Cameron continues to be a show stopper, impressing people worldwide. Similar to the first Avatar movie James Cameron created immense use of cutting-edge performance capture technology. This technology allowed the actors to portray the roles of the alien species, the Na'vi which both films are based on. It shows the great detail of the technology considering the species are 10-feet-tall,blue-skinned, and have pointy ears.

When it came to making the watery scenes come to life, there would be none of the faking the water, actors dangling from wires, feigning weightlessness, making fake swimming motions in the air. According to members of Cameron’s crew, the director insisted on “wet-for-wet.” “Avatar: The Way of Water,” now released since December 2022, symbolizes a new milestone in the evolution of visual effects technology, and that milestone is underwater performance capture.

After some rough testing — the first experiments took place in the backyard pool of an “Avatar” producer names Jon Landau. A performance capture tank was assembled at Lightstorm Entertainment’s facility in Manhattan Beach, California. The tank was 32 feet deep and held around 90,000 gallons. Also created with viewing platforms on the deck and windows in the pool walls for camera operators to shoot through. This gives the tank the look and feel of a laboratory aquarium.

Another one of the main difficulties that the crew had faced was the prevention of overhead studio lights from interfering with performance-capture data. To solve this, James Cameron suggested that spreading a layer of small polymer balls across the water line would diffuse the light in the tank, allowing actors to surface safely from the water.

The artists at Weta who transformed the wetsuited actors into the famous Na’vi. They also created the highly detailed digital environments, taking the action from once a chlorinated tank to an enchanting underwater realm, with major fictional detail. According to the Artists at Weta, about 57 new species of sea creatures were created just for the film. Weta artists also conversed with researchers at Victoria University of Wellington about coral reef biology to get more perspective.

“Avatar: The Way of Water” by far the biggest visual effects project the company has ever taken on. Only two shots in the entire film contain no visual effects.As part of the teams research, the team shot hundreds of hours of reference footage such wind ripples on the surface of water, waves hitting rocks, the movement of seaweed.

James Cameron's "Avatar The Way of Water" continues to make a massive impact in the film industry even after hitting theaters. It was the first of Cameron's Pandora-centered sequels has now grossed $2.074 billion,

Let's take a step back for a moment, please.

Yes, this isn't easy.

Lego did not completely obliterate that argument. Lego has not succeeded yet at meeting their own metrics at a pilot scale, let alone an industrial one. They are testing things to see if they will work well enough, and so far they have not gotten there. Because - yes - bioplastics and recycled plastics do not have the same material properties as standard plastics, and Lego has not finished solving that problem.

As of August 7, 2023, Lego has not provided any more information about their prototype recycled-plastic bricks.

The initial press release announcing their first prototype plastic bricks was from June 2021.

In that release, the team acknowledges that there is still a long path to getting recycled bricks into production. The formulation they have isn't a recycled version of what regular Lego bricks are made of (that's ABS, which isn't commonly recyclable in practice, particularly if colored). It's a modified version of PET, the plastic in single-use water bottles. That plastic is weaker than ABS and Lego is creating a bespoke formulation to get closer to the material properties they need, and they aren't there yet, because this is not easy.

(Even changing the color of a plastic can change its material properties. One standout example of this - there's a case study in which changing a defibrillator case from blue to red-cross red weakened the plastic enough that the case would fail.)

You can check out the WIRED mag article on the subject for more info. Don't take my word for it on the difficulty of this challenge -

Gregg Beckham from the US Department of Energy’s National Renewable Energy Laboratory, who, in 2018 along with Portsmouth University’s John McGeehan, engineered an enzyme that digests PET, is impressed with Lego’s progress. 

“ABS is an amazing material. It is extremely versatile, because you can change the ratio of the A the B and the S. And depending on how you formulate it there are a very large number of versions of ABS plastic that you can make. We literally touch it every day,” Beckham says. “PET, on the other hand, is challenging to formulate in a manner that has the same material properties as ABS like you would find in Lego brick. That is an exceptional polymer science challenge, for sure. This is super exciting.”

As for why it has taken so many decades of plastic production to get to this point, Beckham says that while it would be nice if we could wave a magic wand and just make it happen, in many cases the task is deceptively difficult. “This is fundamental material science and engineering that needs to figure out how to meet the same types of material properties with feedstocks that are either from recycled plastic or become recyclable themselves,” he says. “In the case of ABS bricks, they are neither from recycled plastics nor are they recycled at end of life. This potentially could meet both of those challenges simultaneously.”

And those biobased plastics? They're currently not strong enough (as of this article from Sept 2022) to use for bricks. Only about half of all LEGO sets contain any biobased blocks, and bioplastics represent only about 2% of Lego products.

Side note - because they are colored, both the current ABS and future PET Legos pose major challenges for recycling. Even if they are made of recycled material, they will probably themselves not be recycled.

And lastly - Lego is not unique in its quality control or its standards. Plastic snapping together is extremely common (think of any of the bottles in your fridge whose lids snap closed, think of putting the cap back on a ballpoint pen, think of any number of containers which you can open or close, and then imagine a million more things whose assembly depends on snaps you'll never see). Discarding a mold when it reaches its end of life - everyone does that. Every mold has a limited number of pieces it can make before it wears out. Those things are normal.

No, Lego has it easy. Legos don't have to carry loads. They don't have to be exposed to heat, sunlight, rain, corrosion - any of the perils of the outdoors. They don't have to be safe for food contact, they don't have to hold liquid, they don't have to spin or wear or bend or flex, and they don't matter for human life safety. They aren't like any of the plastic in a car's airbag system which must maintain its performance from brutal cold to scorching heat only to fail perfectly when called upon. They aren't like the ketchup bottle in your fridge which must contain a mildly acidic liquid and keep it airtight. They aren't like the connectors of electrical wires; they're not like the gears in your fan that let it spin for days-hours-years; they aren't like the plastic stint in your great-uncle's heart; they aren't like the soles of your shoes, the chair you sat on in elementary school, the bulletproof windows of the bank, the rubber band around your groceries, or the seal that keeps the oil from spilling out of your bus's engine, the plastic case of the defibrillator in the hospital.

No, Legos get to snap together and sit pretty and still indoors.

There are many, many kinds of plastic. Those plastics do many jobs. Some of those jobs are unnecessary and some of those jobs are very difficult, and specific formulations are necessary to accomplish different tasks. Some things can be recycled mostly-easily, some can be recycled with difficulty, and some cannot be recycled at all because of chemical bonds that form in the plastic. Each has to be sorted and treated differently, and almost all plastics degrade with processing and over their service lives. There is no magic wand. There is only hard work and slightly less hard work.

Don't get me wrong - it is very, very cool that Lego is pursuing biobased and recycled plastics. But it is a pursuit and not a current victory. And it does not mean that the problem of plastics recycling is solved.
