Scientists build a $1,500 open-source 3D metal printer

“Similar to the incredible churn in innovation witnessed with open-sourcing of the first RepRap plastic 3D printers, I anticipate rapid progress when the maker community gets their hands on it,” says Pearce. “Within a month, somebody will make one that’s better than ours, I guarantee it.”

Now, we are getting somewhere.

Stuff I’ve been playing with lately

I have been playing with 3D printing, and variations on the classic dog tag. Here is a model of a “daisy dog tag” that I made for my SweetWife.

I do not have a 3D printer, nor am I planning on buying one in the near future. I am using Shapeways.com, which allows me to have prints made in a variety of materials and colors without having to pay for the “care and feeding” of printers and gives me lots of options. I should be receiving a print of this model in the next couple of weeks.

Now, 3D printing is getting interesting:

Michigan-based Sintercore LLC have developed a range of muzzle brakes that are billed as the first commercial 3D printed firearm parts. Called Auxetik (pronounced Aug-ZETIK), the firearm parts were created using Direct Metal Laser Sintering, an additive metal fabrication technology that fuses metal powder into a solid part by melting it locally using the focused laser beam. Layer by layer parts are built up additively. This process allows for both complex internal features and unconventional external forms. Continue reading

In February, the techie gun-rights group Defense Distributed unveiled a 3D-printed lower receiver for an AR-15 rifle that withstood hundreds of rounds of fire. A YouTube video of the component in action was accompanied by the terse statement, “Does not fail from firing stresses. 600+ rounds.”

Our government collects a lot of information about us. Tax records, legal records, license records, records of government services received– it’s all in databases that are increasingly linked and correlated. Still, there’s a lot of personal information the government can’t collect. Either they’re prohibited by law from asking without probable cause and a judicial order, or they simply have no cost-effective way to collect it. But the government has figured out how to get around the laws, and collect personal data that has been historically denied to them: ask corporate America for it.
