I imagine with this heat wave covering most the country you’re likely on your way to the beach – or at least some place better than work. So with me traveling, Mike suffering through physical therapy, and Rich spending time with the family, this week’s summary will be a short one.

A friend sent me this video earlier in the week – I don’t know if you have seen these before, but if not take some time to look at this video on 3-D printer technology. It’s just one of the coolest things I have seen in years. I originally got interested in this a year or so ago when learning about some of the interesting stuff you can do with Arduino and I remain fascinated. Feed in a CAD design – even with non-connected moving parts – and it will literally print a physical object.

If you notice, the printer in the video uses HP bubblejet printer cartridges – but filled with the resin hardener rather than ink. The technology is simple enough that you could literally build one at home. And pretty much anyone with basic CAD capability can design something and have it created instantly. As 3D printers evolve, so that they support other materials beyond plastic, And these designed can be shared – just like open source software – only in this case it’s open source hardware.

What I find just as interesting is that people keep sending me links to the video, expressing their hopes and visions of the future. When teachers send me the link they talk about using these types of technologies to encourage student interest in technology. When I talk to car enthusiasts, they talk about sharing CAD models of hard-to-find car parts and simply re-fabricating door handles for a 1932 Buick. Star Trek nerds fans talk about the realization of the replicator. When I talk to friends with a political bent who are frustrated that everything is made in China, I hear that this is a disruptive technology that could make America a manufacturing center again. That is more or less the take behind the Forbes video on 3-D printers. Whatever – check out the video.

Blog Comment of the Week

Remember, for every comment selected, Securosis makes a $25 donation to Hackers for Charity. This week’s best comment goes to Betsy, in response to Donate Your Bone Marrow.

As a recent transplant recipient with three close friends also recipients plus a best friend recently diagnosed with leukemia, your post is spot on. Signing up to be a donor is trivially simple and, as you say, a direct path to saving or vastly improving lives.

Visit organdonor.gov for a good source of information on how to donate.

Thanks for your post.
