When 3D printing matured from an industrial edge case to a mainstream commercial technology in the 2010s, it captured the imaginations of everyone from schoolteachers to fashion designers. But if there’s one group that really, really got excited about 3D printing, it was makers. When 3D printers became commercially available, they knew that everything was […]
We’ve all been there: you’re about to start a new print job and the filament on the spool is looking pretty sparse. You start the print hoping that there is enough filament for the job, but it runs out 90% of the way through and your part is ruined. A filament runout sensor will help […]
3D printing, the stuff of science fiction only a few short years ago, is becoming more widely available all the time. Buying your own 3D printer to keep in your home is now fairly accessible, with entry-level printers available for just a few hundred dollars. But why would you buy one? It’s easy to think […]
It seems like everyone who has a substantial net worth carries around a few luxury watches, but none are perhaps as mechanically enthralling as the Twin Turbo Furious watch from Jacob & Co., which houses a pair of spinning orbs called tourbillons that increase the watch’s accuracy. However, they’re quite small and intricate, so seeing […]
3D printing allows us to make a wide variety of shapes, but adding interactive features generally means somehow strapping various electronics to them. The AirTouch project, however, presents an alternative option by enabling a fabricated object to sense up to a dozen different touch points with no components or complex calibration necessary. Instead compressed air is pumped […]
Sure, we’ve seen low-cost DIY 3D printers with wooden frames before, but not a 3D printer that actually ‘prints’ wood. That’s exactly what Shane Wighton and his Formlabs hackathon team have done. (Although probably more along the lines of a hybrid additive/subtractive CNC machine that makes parts out of 3/4″ particleboard.) The device first cuts […]
Arduino boards are great for controlling small servo motors, but what if you need something to provide linear travel? As spotted on Reddit, while the answer here is a little less straightforward, YouTuber Potent Printables has a great solution. It uses 3D-printed components, along with a dab of epoxy and fastener hardware to convert either a micro […]
3D printing, while revolutionary in many aspects, generally means you’re stuck with what you print. Researchers at the University of Colorado Boulder and the University of Tokyo, however, have created a printing system called Dynablock, which attaches specialized magnetic blocks together that can used over and over. The system uses an array of 24 x […]
Air hockey is a classic arcade game consisting of two players, two paddles, a puck, and a low-friction table. But what happens if you don’t have an opponent? If you’re Jose Julio, you build a robotic one out of 3D printer parts. An updated version of his earlier design from 2014, Julio upgraded the Air Hockey Robot’s original camera and vision system to […]
Using ultrasonic sensors attached to a person’s arm, researchers have found a way to let you “feel” distant objects. The concept of this project is surprisingly simple, but as shown in the test video below, seems to work quite well. Using an Arduino Uno to coordinate everything, when rangefinders see a nearby object, like a wall, […]
