Rather than buy a replacement part from a local hardware store, 3D printing offers up the opportunity to produce what you need at home, when you need it. But what if you have to replace a whole unit? If a project from Cornell University's Creative Machines Lab is any indication, such things may soon be possible. A research team has managed to 3D print the cone, coil and magnet of a loudspeaker, and then use it to throw out sounds from a digital audio player.  Read More

Patrick Priebe's laser rifle could be one heck of a tool for highlighting things in a Powe...

German laser weapons hobbyist Patrick Priebe, the creator of such one-off curiosities as the Iron Man Gauntlet and the Crysis 2-inspired Gauss Rifle, has now gone and made a laser rifle. While it won't bring down a storm trooper or an alien facehugger, it'll make short work of things like wood, Styrofoam and glass.  Read More

Using micro meter-fine metal powder, MLS can create tiny components and functioning mechan...

Germany-based companies, 3D-Micromac AG, a provider of laser micromachining systems, and EOS GmbH, an e-Manufacturing group, have teamed up to form a new organization dubbed 3D MicroPrint GmbH. The new enterprise is developing a new micro laser sintering technology (MLS) for 3D printing tiny metal components to meet the demands of Makers and professionals alike.  Read More

The ProJet 4500 3D printer, and one of its creations

Although the things that can be done with 3D printers are certainly amazing, many 3D-printed plastic items still have a certain "look" to them. This is largely due to the fact that each item is all one uniform color. That apparently no longer has to be the case, however, as 3D Systems has unveiled its ProJet 4500. The company describes it as "the industry’s only continuous tone full-color plastic 3D printer."  Read More

After developing some innovative ways to add LEDs to wallpaper, and even the backside of televisions, it looks like Philips is setting its sights on lighting the floor beneath our feet as well. The company recently partnered with Desso, a high-quality carpeting producer, to create a new type of carpet embedded with LEDs that can turn any floor space into a customizable lighting array.  Read More

With 3D printers dropping below the US$200 mark, the home 3D printing revolution appears to be getting into full swing, which is great ... if you want to make things out of plastic. Unfortunately, the price of commercial metal 3D printers means the ability to print metal objects has remained out of reach of most people. That could be set to change with a team from Michigan Technical University building a 3D metal printer for under $1,500.  Read More

Batteries. We buy them at the store, use them up, and throw them away without much thought. In reality, however, batteries are remarkably complex electrochemical devices that are continually evolving. The latest example of this comes from the Lawrence Berkeley National Laboratory, where researchers have invented an advanced lithium/sulfur (Li/S) cell that offers a unique combination of energy storage, power, recharge speed, and survivability.  Read More

Circuit Scribe uses silver ink to draw circuits

A new company called Electroninks is seeking to make DIY electronics child’s play ... literally. Circuit Scribe is a roller-ball pen filled with conductive silver ink that enables the creation of circuits by simply drawing them.  Read More

As a one-atom thick topological insulator, stanene could conduct electricity at full effic...

A team of theoretical physicists from the US Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University is predicting that stanene, a single layer of tin atoms laid out in a two-dimensional structure, could conduct electricity with one hundred percent efficiency at room temperature. If the findings are confirmed they could pave the way for building computer chips that are faster, consume less power, and won't heat up nearly as much.  Read More

Today is Thanksgiving Day in the United States, a holiday in which we celebrate the blessings granted by Life, the Universe, and Everything. A central part of Thanksgiving traditions involves a massive feast, often featuring turkey or ham, and a selection of delicious side dishes. It may soon be possible to virtually experience such a repast as enjoyed by a character in a movie or a video game, aided by a new method for digitally actuating the sense of taste through electrical and thermal stimulation of the tongue.  Read More
