Solar-Powered 3D Printers a Game-Changer for Developing Countries
We've already seen how 3D printing can tackle plastic waste and even create nutritious food. And now, the ever-expanding technology is also bringing simple yet potentially life-saving devices to people in developing countries.
Joshua Pearce, a materials science and engineering professor at Michigan Technological University, invented the first mobile, solar-powered 3D printer. His website shows a whole range of 3D printing possibilities, such as wind turbines, hand-cranked power generators, medical braces, breast pumps, prosthetic leg covers, water spouts and more.
Incredibly, his designs are open-source, which means people can use, study, copy and change a design for free, he told The Guardian.
The prospect of using solar-powered printers is especially important for locations that have little to no access to electricity or when power has been destroyed by a natural disaster such as an earthquake. As we mentioned previously, about a quarter of the world’s population—1.6 billion people—live without electricity.
It could also produce important devices at pennies to the dollar. For example, Pearce's lab created an open-source 3D printable colorimeter for testing water which cost only $50 and worked just was as well as one costing $2,000.
In Haiti, the nonprofit organization Field Ready and their partners are working to make medical devices as varied as umbilical cord clamps, IV bag hooks, oxygen tank valves and even prosthetic limbs using 3D printers.
In the video below, Dara Dotz, Field Reader designer and co-founder described how a simple umbilical cord clip could be printed out in under 10 minutes. She also pointed out the importance of producing products on-demand in the onset of disasters, such as the 2010 Haitian earthquake.
"During the earthquake, the airport was actually overflowing with a bunch of materials, some of which were not needed," she said. "[But] the tools and medication that were needed couldn't actually get access because of the congestion."
In other sustainability measures, the organization is training and hiring local residents to use 3D printers and also piloting the use of recycled plastics in order to cut waste. They also hope to eventually switch to solar-powered 3D printers, as their current printers run on batteries and generators.
"The items that we can actually manufacture tend to be small but the ability to make many different things is what's really unique about it," Eric James, the director of Field Ready, said. "As long as we have the basic power source and the designs, we can fabricate virtually anything that would be needed."
As 3D printing technology becomes more and more affordable, the possibilities for manufacturing scientific equipment and medical supplies are endless. Peter Bermant, a senior at Park City High School in Utah, used a 3D printer to create a concept syringe that could mix vaccine ingredients as it's injected into a patient, eliminating the need for refrigeration (a costly hurdle for off-grid communities). A University of Washington team of students used 3D printing to turn waste plastic into composting toilets and rainwater harvesting systems.
The video below shows Alois Mbutura, a 21-year-old electrical engineering student at the University of Nairobi in Kenya, who used a MakerBot 3D printer to create an affordable medical device that helps doctors administer intravenous needles to infants. It's said that about 100 of these devices could be produced in a day using the 3D printer.
"The vein finder was actually a solution that the School of Health and School of Engineering partnered to reduce the inability of health care people to find veins in babies and also for it to be economical and suited to Kenya," said Mbutura.

1. Stay Informed<p>A first order of business in pet evacuation planning is to understand and be ready for the possible threats in your area. Visit <a href="https://www.ready.gov/be-informed" target="_blank">Ready.gov</a> to learn more about preparing for potential disasters such as floods, hurricanes, and wildfires. Then pay attention to related updates by tuning <a href="http://www.weather.gov/nwr/" target="_blank">NOAA Weather Radio</a> to your local emergency station or using the <a href="https://www.fema.gov/mobile-app" target="_blank">FEMA app</a> to get National Weather Service alerts.</p>
2. Ensure Your Pet is Easily Identifiable<p><span>Household pets, including indoor cats, should wear collars with ID tags that have your mobile phone number. </span><a href="https://www.avma.org/microchipping-animals-faq" target="_blank" rel="noopener noreferrer">Microchipping</a><span> your pets will also improve your chances of reunion should you become separated. Be sure to add an emergency contact for friends or relatives outside your immediate area.</span></p><p>Additionally, use <a href="https://secure.aspca.org/take-action/order-your-pet-safety-pack" target="_blank" rel="noopener noreferrer">'animals inside' door/window stickers</a> to show rescue workers how many pets live there. (If you evacuate with your pets, quickly write "Evacuated" on the sticker so first responders don't waste time searching for them.)</p>
3. Make a Pet Evacuation Plan<p> "No family disaster plan is complete without including your pets and all of your animals," says veterinarian Heather Case in <a href="https://www.youtube.com/watch?v=Q9NRJkFKAm4" target="_blank">a video</a> produced by the American Veterinary Medical Association.</p><p>It's important to determine where to take your pet in the event of an emergency.</p><p>Red Cross shelters and many other emergency shelters allow only service animals. Ask your vet, local animal shelters, and emergency management officials for information on local and regional animal sheltering options.</p><p>For those with access to the rare shelter that allows pets, CDC offers <a href="https://www.cdc.gov/healthypets/emergencies/pets-in-evacuation-centers.html" target="_blank">tips on what to expect</a> there, including potential health risks and hygiene best practices.</p><p>Beyond that, talk with family or friends outside the evacuation area about potentially hosting you and/or your pet if you're comfortable doing so. Search for pet-friendly hotel or boarding options along key evacuation routes.</p><p>If you have exotic pets or a mix of large and small animals, you may need to identify multiple locations to shelter them.</p><p>For other household pets like hamsters, snakes, and fish, the SPCA recommends that if they normally live in a cage, they should be transported in that cage. If the enclosure is too big to transport, however, transfer them to a smaller container temporarily. (More on that <a href="https://www.spcai.org/take-action/emergency-preparedness/evacuation-how-to-be-pet-prepared" target="_blank" rel="noopener noreferrer">here</a>.)</p><p>For any pet, a key step is to establish who in your household will be the point person for gathering up pets and bringing their supplies. Keep in mind that you may not be home when disaster strikes, so come up with a Plan B. For example, you might form a buddy system with neighbors with pets, or coordinate with a trusted pet sitter.</p>
4. Prepare a Pet Evacuation Kit<p>Like the emergency preparedness kit you'd prepare for humans, assemble basic survival items for your pets in a sturdy, easy-to-grab container. Items should include:</p><ul><li>Water, food, and medicine to last a week or two;</li><li>Water, food bowls, and a can opener if packing wet food;</li><li>Litter supplies for cats (a shoebox lined with a plastic bag and litter may work);</li><li>Leashes, harnesses, or vehicle restraints if applicable;</li><li>A <a href="https://www.avma.org/resources/pet-owners/emergencycare/pet-first-aid-supplies-checklist" target="_blank">pet first aid kit</a>;</li><li>A sturdy carrier or crate for each cat or dog. In addition to easing transport, these may serve as your pet's most familiar or safe space in an unfamiliar environment;</li><li>A favorite toy and/or blanket;</li><li>If your pet is prone to anxiety or stress, the American Kennel Club suggests adding <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">stress-relieving items</a> like an anxiety vest or calming sprays.</li></ul><p>In the not-unlikely event that you and your pet have to shelter in different places, your kit should also include:</p><ul><li>Detailed information including contact information for you, your vet, and other emergency contacts;</li><li>A list with phone numbers and addresses of potential destinations, including pet-friendly hotels and emergency boarding facilities near your planned evacuation routes, plus friends or relatives in other areas who might be willing to host you or your pet;</li><li>Medical information including vaccine records and a current rabies vaccination tag;</li><li>Feeding notes including portions and sizes in case you need to leave your pet in someone else's care;</li><li>A photo of you and your pet for identification purposes.</li></ul>
5. Be Ready to Evacuate at Any Time<p>It's always wise to be prepared, but stay especially vigilant in high-risk periods during fire or hurricane season. Practice evacuating at different times of day. Make sure your grab-and-go kit is up to date and in a convenient location, and keep leashes and carriers by the exit door. You might even stow a thick pillowcase under your bed for middle-of-the-night, dash-out emergencies when you don't have time to coax an anxious pet into a carrier. If forecasters warn of potential wildfire, a hurricane, or other dangerous conditions, bring outdoor pets inside so you can keep a close eye on them.</p><p>As with any emergency, the key is to be prepared. As the American Kennel Club points out, "If you panic, it will agitate your dog. Therefore, <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">pet disaster preparedness</a> will not only reduce your anxiety but will help reduce your pet's anxiety too."</p>
Evacuating Horses and Other Farm Animals<p>The same basic principles apply for evacuating horses and most other livestock. Provide each with some form of identification. Ensure that adequate food, water, and medicine are available. And develop a clear plan on where to go and how to get there.</p><p>Sheltering and transporting farm animals requires careful coordination, from identifying potential shelter space at fairgrounds, racetracks, or pastures, to ensuring enough space is available in vehicles and trailers – not to mention handlers and drivers on hand to support the effort.</p><p>For most farm animals, the Red Cross advises that you consider precautionary evacuation when a threat seems imminent but evacuation orders haven't yet been announced. The American Veterinary Medical Association has <a href="https://www.avma.org/resources/pet-owners/emergencycare/large-animals-and-livestock-disasters" target="_blank">more information</a>.</p>
Bottom Line: If You Need to Evacuate, So Do Your Pets<p>As the Humane Society warns, pets left behind in a disaster can easily be injured, lost, or killed. Plan ahead to make sure you can safely evacuate your entire household – furry members included.</p>
