Have you ever felt like your surroundings are spinning? That's vertigo, and it's a tricky condition to diagnose. Doctors face a challenge because symptoms can be elusive, especially during routine exams. But here's a fun fact: our eyes can reveal a lot about what's happening in our brains. Conditions like benign paroxysmal positional vertigo (BPPV), Ménière's disease...
Imagine this: getting braces that fit perfectly, feel great, and might even work faster. That's what 3D-printed orthodontic appliances are promising. These aren't your average braces or retainers. They're custom-made just for you, using advanced 3D printing technology. This isn't just about looks, but also about comfort and efficiency. But let's talk about t...
Building bones from scratch for medical needs is a hot topic in science. 3D printing is a big deal in this field. It's all about creating materials that match real bone tissue. This is tricky because bones have a complex structure. Scientists are exploring new ways to make this happen. Imagine printing bone structures that are as intricate as a spider web. T...
Ever wondered how those custom-made teeth aligners are made and if they're safe? A recent study looked into the safety of 3D-printed aligners made from a material called Tera Harz TA-28. These aligners can have different thicknesses, which might affect how long they need to be cured under UV light to ensure they're safe for your mouth. Scientists printed aligners of ...
Dr. Smith knows that growing new heart tissue in the lab is tricky. One challenge is making sure the tiny scaffolds that support the cells have the right shape. They should mimic the native heart's structure, like the way muscle fibers line up. Recently, Dr. Smith and their team tried something new. They created a 3D-printed scaffold using a flexible plastic called ...
When it comes to growing new bones, scientists are exploring how to design the best scaffolds for the job. These scaffolds need to be good at helping new bone grow and strong enough to hold up. Researchers have looked at different types of materials, like metals, non-metals, and polymers, to make these scaffolds. They've also considered different ways to make these s...
Ever wondered how heat affects the strength and shape of dental 3D printing resins? Scientists decided to find out by heating resins to different temperatures during the 3D printing process. They used a special tank to keep the resin warm at 30, 40, and 50 degrees Celsius. They tested how well the resin flowed, how fast it hardened, how tough the surface was, how fle...
Three-dimensional printing has revolutionized the way we think about creating tissue replacements. What makes this technique so versatile is the ink used to print the tissues. Ideally, this ink should be safe to use in the body, stable, and capable of maintaining its shape, size, and function after printing. Enter liquid collagen ink, a cutting-edge development in th...
Imagine you need a super-strong, lightweight groove structure for an industry application. Sounds easy, right? Well, not quite. Traditional methods make this task pretty tricky. This is where a creative mix of 3D printing and filament winding comes into play. We're talking about a groove structure that's not only tough but also light. The challenge is that these str...
Researchers have decided to take a closer look at how strong dental crown materials are. They're not just checking the traditional milled zirconia, but also two new types made with 3D-printing technology. This method is officially called 3D-LCM (Liquid Crystal Monomer). Now, you might be wondering how they're testing these materials. Well, they're using a fancy tool ...
