Workholding is generally not a problem on a big CNC plasma cutter.; gravity does a pretty good job of keeping heavy sheet steel in place on the bed. But what …read more Continue reading Electromagnets Make Vertical CNC Cutter a Little Stickier
Using a cold plasma jet to activate hydrogel, researchers have created a dressing with antibacterial and wound-healing properties. The technology could be used as an alternative to current treatments that rely on antibiotics to treat chronic wounds, su… Continue reading Stubborn wounds meet their match in cold plasma jet-charged dressing
For the most part, here at Hackaday we’re more interested in how something was made than the backstory on why an individual actually put it together. Frankly, it’s not really …read more Continue reading 20,000 Volt plasma Knife Slices, Dices, and Sparks
Researchers have devised an economically viable way of reducing the environmental impact of both the steel and aluminum industries by using hydrogen to melt down the toxic red mud left over from aluminum production to produce green steel in around 10 m… Continue reading Researchers create green steel from toxic red mud in 10 minutes
Metalworking has always been very much a “mixed method” art. Forging, welding, milling, grinding; anything to remove metal or push it around from one place to another is fair game …read more Continue reading Plasma Cutting and 3D Printing Team Up to Make Bending Thick Sheet Steel Easier
For doing basic steel welding, most of us will reach for a MIG welder. It might not be the best tool for every welding job, but it’s definitely the most …read more Continue reading High Voltage Turns Welder into Plasma Cutter
Researchers have used plasma technology to transform a species of blue-green microalgae into a bioactive coating with incredible wound-healing properties. They say the novel coating can be applied to dressings and medical devices to protect patients fr… Continue reading Plasma tech transforms blue-green algae into a wound-healing wonder
Plasma cutters are ridiculously cheap these days, just cruise by the usual online sources or your local Harbor Freight if you’ve got any doubt about that. But “cheap” and “good” …read more Continue reading Simple Add-On Makes Cheap Plasma Cutter Suitable for CNC Use
A little over a year ago, and about 150 million kilometers (93 million miles) from where you’re currently reading this, NASA’s Parker Solar Probe quietly made history by safely flying …read more Continue reading NASA’s Parker Probe Gets Front Row Seat to CME
A team of scientists led by University of Virginia professor Patrick Hopkins is developing a plasma “freeze ray” that will be less interesting to super villains than to engineers looking for ways to cool electronics in the vacuum of space.Continue Read… Continue reading Plasma pulses promise real-life ‘freeze ray’
