Watch an incredibly detailed work of art emerge from a sheet of metal at LasX Industries Inc. as it’s burned using an impressively quick computer-guided laser beam. The sound it makes is nearly as satisfying as the visuals.

This incredible tech from DMG MORI is a single machine that can create metal objects using a process called laser deposition welding, which melts a metallic powder into a desired form. It can then mill the parts to further refine them.

So you loved Karen O’Leary’s intricate handmade map but can’t afford it? CutMaps has the next best thing – a series of laser-cut maps from sheets of steel, EVA foam, or plywood. While the stainless maps are small, they’re a total bargain.

If you think Jaimie Mantzel’s Attacknids are cool, check out what DIY Laser Guy did to the toy robot. He attached a 5W blue laser to a Stryder Attacknid and made it so he could fire the blinding beam via remote. Pew pew at 1:05.

Want to get layers of dirt and grime off your stuff? Why not hit it with a 500-watt laser beam like these guys. To put things in perspective, the searing bright Spyder III Arctic laser has 1 watt. Not clean enough for you? Try 1000 watts.

Wicked Lasers is constantly harping on about how powerful – and dangerous – its 500mW Spyder III Krypton laser is. Well, YouTuber styropyro’s homemade laser produces a 3W beam. Watch it destroy a bunch of objects.

Engineer Amanda Ghassaei has come up with a method to use a laser cutter to create playable records using wood instead of vinyl. While the sound fidelity isn’t great, we’re still impressed that they play at all. Learn how at Instructables.

What happens when you point a custom-made 500 milliwatt Blu-ray laser beam at a line of 100 black balloons? This, my friends, this. It takes the powerful laser just eight seconds to sear through every single one of the balloons.
