HP’s Partner Network Teams Up to Battle COVID-19 with Simple Designs & 3D Printed Innovations

Normally, this is the time of year when we’re fielding a constant flood of press releases, firming up travel plans, and starting to set interview schedules for the annual 3D printing extravaganza that is RAPID + TCT. But SARS-CoV-2, otherwise known as COVID-19 or the coronavirus, has changed all that. On top of nearly all major additive manufacturing shows in the near future (and the Tokyo Olympics) being canceled, the pandemic is wreaking havoc elsewhere as well.

According to the World Health Organization, there are currently close to 400,000 cases of the disease around the world, with that number rising every day, and we’ve all added the phrase “social distancing” to our vocabulary. On a personal note, I’m a frequent theatre volunteer, and the shows I was working on have either been postponed or canceled. Last night, I delivered groceries (though not toilet paper) to my 94-year-old grandparents since they’re not supposed to leave the house, waved to my mother from six feet away, and I’ve participated in numerous Zoom conferences and FaceTime calls with friends over the past week, since Ohio is under a “stay at home” order.

But, as the above quote from beloved American TV personality Fred Rogers says, you can always find people who are helping during the hard times. HP Inc. is one of those helpers: the company, along with its digital manufacturing community, is mobilizing its 3D printing experience, technology, production capacity, and teams to help find solutions for the worldwide battle against COVID-19.

“HP and our digital manufacturing partners are working non-stop in the battle against this unprecedented virus,” stated HP’s President and CEO Enrique Lores. “We are collaborating across borders and industries to identify the parts most in need, validate the designs, and begin 3D printing them. Our deepest appreciation goes to our employees, partners, customers, and members of our community for their tireless efforts to support the medical professionals making a difference on the front lines.”


HP’s worldwide network of digital manufacturing and production partners has stepped up to the plate to create and deliver 3D printed critical parts during this pandemic to help support the global health community, and more than 1,000 parts have been delivered to local hospitals already. The company’s 3D R&D centers in Washington, Oregon, California, and Spain are banding together, working with partners all around the world to ramp up production of these parts in order to help the healthcare sector meet the urgent needs of its many patients, and contain the spread of COVID-19, through 3D printing.

Because HP’s network of manufacturing partners is global, these 3D printed parts should be available to hospitals in any region in the world. The company is working with industry, health, and government agencies to make sure that the approach is effective and synchronized, and its partners are making many of their validated 3D design files available for download free of charge here. The available designs consist of parts that don’t require complex assembly, so that production can keep up its accelerated pace.

There are several important applications that have already been finalized for industrial 3D printing, such as respirator parts and nasal swabs. Another is a face shield, which is one of the personal protection items in high demand at the moment. A critical component of these shields are 3D printable brackets that help ensure a comfortable fit.

Thousands of 3D printed mask adjusters were delivered in China and Spain.

Hospital staff are often required to wear face masks for extended periods of time now. A 3D printed mask adjuster features a clasp that helps provide the wearer with some relief from ear pain caused by wearing their masks for so long.

One of the most germ-infested items in any hospital, home, or workplace is the door handle – just think how many different people have touched it in a 24-hour period! On second thought, maybe don’t think about it. But a 3D printed adapter makes it possible to easily open doors with your elbows: a hands-free option that obviously keeps things much cleaner.

Plenty of other 3D printed applications to help contain COVID-19 are currently in the testing and validation phase, and production for these should start in the coming days and weeks. One such example is the FFP3 face mask, which helps protect medical providers as they treat a higher volume of patients. HP is currently validating multiple hospital-grade 3D printable face masks, and they should be available soon.

A simplified design that requires 3D printed parts for a field ventilator is also being validated. The mechanical bag valve mask (BVM) was designed to provide short-term emergency ventilation to patients with COVID-19, and while it’s definitely an important application, the design makes the device simple yet strong, which helps speed up the production and assembly process.

3D designers who are interested in helping fight COVID-19 can visit this HP website to contribute ideas and applications. If you, or someone you know, would like to order parts that can help in the pandemic battle, or require support with application development, requests can be submitted here. Be safe, be smart, and stay healthy!

Researchers Use 3D Printing and Basic Electronic Components to Make Neuroscience More Accessible

While I was worse in math, science was also not one of my strong suits in school. So anything that makes it easier for students to better understand these complex subjects is a good idea, in my humble opinion. Tom Baden, a professor of neuroscience at the University of Sussex, has been collaborating with his colleagues to further open up access to science education with a piece of hardware that can demonstrate how our brains function.

“By making access to scientific and teaching equipment free and open, researchers and educators can take the future into their own hands,” Professor Baden said. ” In time, we hope that this type of work will contribute to level the playing field across the globe, such that ideas, not funding can be the primary driver for success and new insights.”

Professor Baden is also one of the scientists behind the innovative 3D printable FlyPi microscope, and his latest work – an educational model of neurons in the brain made with basic electronic components – is just part of his expanding range of equipment that uses DIY and 3D printable models to make science more accessible and interactive.

One of the central parts of neuroscience is, of course, understanding how our neurons encode and compute information. But there’s not a good hands-on type of way to learn about this…until now. Professor Baden and other colleagues are building Spikeling: a piece of electronic kit which behaves similarly to the neurons in the brain and costs just £25.

“Spikeling is a useful piece of kit for anyone teaching neuroscience because it allows us to demonstrate how neurons work in a more interactive way,” Professor Baden explained.

Professor Baden, together with researchers Ben James, Maxime J.Y. Zimmermann, Philipp Bartel, Dorieke M Grijseels, Thomas Euler, Leon Lagnado and Miguel Maravall, published a paper about their work on Spikeling in the open access journal PLOS Biology, titled “Spikeling: a low-cost hardware implementation of a spiking neuron for neuroscience teaching and outreach.”

The team hopes that their invention will end up being a useful neuroscience teaching tool, and in fact, they are already seeing the benefits of their hard work. A class of third year neuroscience students at the university have used the kit, and at a Nigerian summer school last year, scientists were also taught how to build the hardware from scratch.

Spikeling has receptors, which react to external stimuli such as light to simulate how information is computed by nerve cells in the brain. Then, students can follow the activity of the receptors, or cells, live on a computer screen. Users can also link several Spikelings together to form a network, which demonstrates how brain neurons interconnect. This action makes it possible to demonstrate the neural behavior behind every day actions, such as walking.

The goal in Professor Baden’s lab is to, as the university put it, “level the playing field in global science” and make necessary equipment less expensive than it usually is. That’s why all of the information and design files for Spikeling have been made available, joining a growing trend around the world of designs collected on the PLOS Open Hardware toolkit, which Professor Baden just so happens to co-moderate.

“With all parts being cheap, and design files being free and open, we hope that like any open Hardware design, Spikeling can be a starting point for others to change or extend it to their requirements, and reshare their improved design with the community,” Professor Baden said.

Andre Maia Chagas, one of the research technicians in the lab, recently published his own article in PLOS Biology that explains the importance of open scientific hardware, in response to a piece by Eve Marder, an American neuroscientist who wondered if researchers who worked in less wealthy institutions would fall behind as scientific research equipment continues to grow more expensive. More and more, we’re seeing that 3D printing can be used to make sure this doesn’t happen.
