Many of us have wondered at least for one time that how do people precisely cut materials like stainless steel, aluminum, brass, and copper? Well, they basically use a technique called plasma cutting ...

Wookiepedia, the Star Wars Wiki, says that lightsabers have no feel because the "blade" has no weight. All the heft is in the hilt. That means a lightsaber-wielder has no definitive sense of the light ...

Behold the awesome glory of the plasma cutter. These torches create electrically conductive jets of hot plasma that will cut through just about any conductive material, from steel to to brass. In the ...

What we want is a Star Trek-style replicator. What we have are a bunch of different machines that can spew out various 2D and 3D shapes. For the foreseeable future, you’ll still need to post-process ...

Little Shop of Physics has built a miniature plasma cutter using a pencil lead together with 4 x 9 volt batteries and a couple of clips allowing you to cut through aluminium foil. Watch the video ...

Plasma is superheated, compressed air that ionizes to form a conductive gas. This gas conducts electricity from the torch of the plasma cutter to the work piece, through a electrode and copper nozzle ...

If you’ve ever used a plasma cutter or watched someone else use a plasma cutter, you know it’s tough to go back to metal shears and a reciprocating saw for slicing up metal. A plasma cutter makes it ...

To the naked eye, someone slicing through steel using a high-temperature plasma torch just looks like a massive shower of sparks. But through the lens of a high-speed camera filming at 480 frames per ...

Nearly all fumes from plasma cutting contain toxic substances, but the composition varies depending on the metal being cut ...
