Drugs like amphetamine are often used in crimes, especially at parties and clubs. These drugs can be dangerous, and detecting them quickly is important. Traditional methods for detecting these drugs are slow and complicated. Now, there's a new tool that could change the game. It's a wearable device
A young innovator has created a compact powerhouse for 3D printers. This isn't just another small tweak. It's a whole new brain for these machines. The creator, a 17-year-old tech whiz, designed a control board called the Cheetah MX4 Mini. It's small, about the size of a drink coaster. But don't let
Lactate is a substance your body makes during exercise or when you're sick. Doctors need to measure it to understand your health. But there's a problem: too much lactate can mess up the tests. Scientists have found a solution. They made a tiny tool, a biosensor, to measure lactate accurately. This
Bone repairs are tricky. Current materials often fall short. They struggle to balance strength and function. But there's hope. Inspired by nature, scientists are using 3D printing to create new materials. These are not your average implants. They are special. They are bicontinuous interpenetrating-p
Scientists have made a big step forward in healing soft tissues. They created a special gel that can be 3D printed. This gel is made from a protein that acts like collagen, a key part of our skin and other soft tissues. The gel is special because it forms under normal conditions. It doesn't need ha
China has made a big step in making its own airplane engines. They tested a small, super-light turbojet engine. This engine is special because it was mostly made using 3D printing. The test showed that the engine can work well on its own, not just in controlled tests. The engine powered a drone for
Metal 3D printing is a game-changer. It constructs objects layer by layer from a digital blueprint. The melt pool, a hot, liquid area, is crucial for the final product's quality. Monitoring this pool helps in identifying flaws and predicting how the material will act. Different 3D printers use vari
The world of medicine is always looking for better ways to get drugs into our bodies. One exciting new idea is using tiny, hollow needles made by 3D printers. These microneedles are much smaller than the ones used in shots. They can deliver medicine through the skin without causing much pain or dama
Tiny robots are making big waves in medicine. These little helpers, called microrobots, can move around without wires. They could one day help doctors treat patients without surgery. But there's a problem. Most microrobots are made from soft materials. They can't move well in fast-flowing blood. The
3D printing is getting smaller and more precise. LCD-based 3D printing is a budget-friendly way to make tiny microfluidic devices. But, it's not perfect. The problem? Sticky resin and wobbly release films can mess up the tiny details. Here's a clever fix: sticky tape. By adding transparent double-s
