Speaker 1: You are listening to freak type science. Did you know that three D printers can print chocolate? What I wonder if they will one day be able to create cookies. Hello, friends, and welcome back to sleep Tight Science, a bedtime show that answers your questions about science. We are kicking off season four with even more exciting science topics, answering your questions and sharing fun and interesting facts. We've heard your feedback and are making a few weeks there will be more relaxing sounds and many more episodes. From now on, sleep Tite Science will release a new episode every week. So let's get started with our first topic. In this episode, we are going to learn all about three D printing. You've probably heard about printers that print on paper, right. You might have one at home, in your school or at the library. But imagine a printer that can make actual objects, like a toy you designed yourself. That's exactly what a three D printer does, and it's changing the way we create things in all kinds of exciting ways. Three D printing is a special kind of technology that builds objects layer by layer, almost like stacking super thin pieces of paper to create a three dimensional shape. Instead of ink, three D printers use materials like plastic, metal, or even rubber to create all sorts of objects. The printer follows a computer design known as a three D model, and slowly builds the object from the bottom to the top. It's kind of like magic, but with science. So how does this all work? Imagine you wanted to make a toy of some kind, like maybe a car. First, you design the car on a computer using special software that helps create a three D model. Then the three D printer reads this design and starts printing it by laying down thin layers of melted plastic, one on top of the other, until TOADA, your toy car is complete. What we find cool is that three D printers can make almost anything. People use three D printers to create custom toys, tools, broken parts for other things, and even musical instruments. But that's not all. In the medical world, three D printing is used to make prosthetic limbs for people who need them, and models of organs that help doctors practice surgeries. There are even scientists working on ways to print human tissue like skin or muscles, which could help save lives in the future. Even astronauts use three D printing. When they're in space, they can't just run to the store if they need a tool or a part for the space station. Instead, they use a three D printer to make the things they need right there in space. One of the most awesome things about three D printing is how flexible it is. Traditional manufacturing involves cutting or shaping things out of bigger materials, which can be wasteful, But with three D printing, you only use what you need, making it much more efficient. LUs It allows people to create custom designs and build things that wouldn't be possible using other methods. Three D printing also makes it easier to create prototypes. What's a prototype. It's like a rough draft of an object. Let's say you're inventing a new toy. You can three D print a prototype, test it, and then make improvements before you create the final version. This saves time and money and helps inventors get their ideas off the ground faster. The future of three D printing is pretty exciting. Scientists are exploring ways to use it for even more amazing things like building houses, printing food, and creating body parts. Maybe you have seen a movie where the character just pushes a button and their dinner appears right before them. Imagine living in a world where you could three D print an ice cream or pizza, or print a new toy whenever you wanted. What would you want to create? Did you know that three D printing can help protect endangered animals. Scientists are working on printing artificial horns to stop poaching of animals like rhinoceros. One of the most prevalent materials three D printers used right now is plastic, but they can also use a variety of other materials depending on what's being printed. The most common types of plastic used in three D plas printing are PLA, polylactic acid, and ABS which is such a hard name to say, acrolonitril butidiodine styrene. These plastics are melted and layered to create objects, making them great for things like toys, prototypes, and tools. There are also three D printers that can work with metal resin rubber, and even wood based or ceramic materials. For example, in industries like aerospace or healthcare, three D printers use metal to create strong, precise parts. As Mean and his twin sister as Heene, who are six years old and live in Melbourne, Australia recently asked us about how plastic is made. We have a whole episode devoted to the topic called do you Know about Plastics? But I think a short refresher might be a good idea. So, plastic is made from crude oil that comes from deep underground. Crude oil is a thick, gooey liquid full of tiny molecules. These tiny molecules are the building blocks for making plastic. The oil is heated up in a factory. The heat separates the oil into different parts, one of which is called naphtha. This is the part that's really important for making plastic. Next, naptha is broken down into tiny parts called monomers. These monomers are stuck together to form long chains called polymers, which make up plastic. The plastic is then melted and shaped into tiny pellets, which can be turned into the materials we can use in three D printers. Did you know that you can three D print shoes? Companies like Adidas are using three D printing to make custom designed sneakers. Imagine designing your own toy from scratch and then watching it come to life right before your eyes. That's what three D printing can do. Now that we know how three D printers work, let's look at how three D printing makes toys. It all starts with a design. Using a computer program, toy makers or even you create a three D model of the toy, like a spaceship, a doll, or a cool figure from your imagination. Once the design is ready, the three D printer gets to work. It melts down plastic and prints the toy layer by layer, just like stacking thin slices of bread into a sandwich. In the end, you have a brand new toy that's exactly how you designed it. But three D printing isn't just for regular toys. It can make custom made toys too. You can choose the colors, size, and shape, and even make changes to the design if you want. Whether you're dreaming up a new board game piece or your very own superhero, three D printing you create toys that are totally unique and made just for you. Before three D printing, toy companies had to make big molds for every toy. Once they made a mold, all the toys came out looking exactly the same. It took a lot of time and money to change designs, so new toys weren't created quickly, But with three D printing, designers can skip mold making and go straight to printing their ideas. They can test out new toys much faster, make changes right away, and bring their ideas to life in no time. This has had a big effect on the toy industry. Now even smaller toy makers can get in on the fun, and people at home can design and print their own toys. Imagine not having to buy the same toy as everyone else, but getting something that's personalized just for you. You could have a custom action figure, a special game piece, or even print a toy you dreamed up. That means more creativity and personalization than ever before. Three D printing has made it possible to design and create toys faster, cheaper, and more creatively. Whether you're a big company or a kid with a big imagination, three D printing gives you the power to make toys exactly the way you want. It's not just about buying toys anymore, it's about creating your own. So the next time you play with a toy, think about how three D printing might be involved. What toy would you up? Did you know that three D printing has helped create prosthetic limbs for animals. A three D printed leg helped a duck named Buttercup walk again. So we've talked about how three D printing can create toys that are customized and unique. But did you know that three D printing is also being used to revolutionize the medical field. While three D printing is great for making fun things, it's also helping doctors and scientists create tools, body parts, and even prosthetics to im prove people's lives. Remember how three D printing lets you design custom toys, Well, it's doing the same thing with prosthetics, which are artificial body parts like hands, legs, or feet. Before three D printing, making a prosthetic was a long, expensive process, But now doctors can design and print prosthetics that fit a person's body perfectly, and they can do it much faster. This is especially awesome for kids who need prosthetics because they grow quickly and need new ones as they get bigger. We read more than one story about a kid who, thanks to three D printing, got a custom prosthetic hand that allowed them to play sports, draw and do everything they wanted. It was designed just for them, making them feel more comfortable and confident. But three D printing doesn't stop at prosthetics. It's also being used to create surgical tools for doctors. Surgeons need very precise tools to operate, and three D printers can make custom tools for each surgery. For example, suppose a doctor is working on someone's bones. In that case, they can print tools that fit that person's body exactly, helping make the surgery safer and smoother. Doctors are even using three D printing to create models of patient's organs before surgery. For example, if a doctor is preparing to operate on someone's heart, they can print a model of the heart to practice on before they start the actual surgery. This helps doctors get everything just right now. This is a bit like science fiction, but scientists are also working on three D printing organs. In the future, doctors might be able to print human organs like hearts, kidneys, and livers. They're still working on it, but they've already started printing simpler things like skin and blood vessels. Imagine someone who needs a new kidney. Instead of waiting for a donor, doctors could print a new kidney using the person's own cells. That way, the body is more likely to accept the new organ and it could save lives by making organ transplants faster and more available. Just like three D printed toys bring joy and creativity, three D printed medical devices are changing lives for the better. In this episode, we began by learning what three D printing is and how it works. Three D printing is a special technology that creates objects layer by layer using materials like plastic, metal, or even rubber. It all starts with a three D design on a computer, and then the printer reads this design and builds the object from the bottom up. Three D printers are used to create all kinds of things, from toys, to tools, and even objects for space missions. Next, we learned how plastic is made. Plastic starts from crude oil, which is heated and broken down into tiny building blocks called monomers. These monomers are combined to form long chains called polymers, the main material in plastic. The plastic is shaped into pellets, which are used to make everything from toys to bottles, and even parts for cars. Then we explored how three D printing makes toys. Unlike traditional manufacturing, which uses molds, three D printers build toys layer by layer using plastic and other material. The coolest part, three D printing allows for custom made toys. You can design your own toy, choosing the colors, shape, and size, making each toy unique. This has revolutionized the toy industry by allowing designers to quickly test new ideas and bring creativity to life. Finally, we discovered how three D printing is changing medicine. Doctors use three D printers to create prosthetics, surgical tools, and even practice models of organs. Prosthetics made with three D printers can be custom fitted and are more affordable, helping people worldwide. Scientists are even working on printing human organs like hearts and kidneys to help save lives in the future. From toys to day medicine, three D printing is transforming industries by making production faster, more creative, and more accessible. The possibilities are endless.
