DIY 3D printer utilizes hot air, sugar to craft random objects - Engadget

Just when you thought a $5,000 3D printer wasn't such a bad deal after all, the zany gurus at the Evil Mad Scientist Laboratories have put Desktop Factory's iteration to shame. The CandyFab 4000 is a homegrown printer that utilized a bevy of miscellaneous spare parts around the lab as well as the same sort of CNC hot-air control mechanism that we previously saw in the text writing toaster contraption. Their selective hot air sintering and melting (SHASAM) method allows the printer to begin with a bed of granular media (sugar, in this case) in which a directed, low-velocity beam of hit air can be used to fuse together certain areas repeatedly, eventually working the remaining grains into a three-dimensional object. The creators claim that while their CandyFab machine only ran them $500 in addition to junk parts and manual labor, even starting from scratch shouldn't demand more than a grand or so, so be sure to click on through for a few snaps of the fascinating results and hit the read link for the full-blown skinny.

Remember two posts downwhen where I suggested that Second Life may become the AOL of virtual realities? Here's another post saying the same thing:

Techdirt: Will Second Life Be The AOL Of Online Virtual Worlds?

Perhaps one way to think of it is that Second Life is similar to the early closed online services like Prodigy, AOL and Delphi. Eventually, they all were forced to move towards the open internet that no one controlled (some slower than others). An "open source" Second Life could certainly represent the internet in such a scenario, taking away the more limited situation of Second Life, and allowing for much more interesting social and economic experiments.

Some of the comments are worth reading, too. (Others are perfect examples of Sturgeon's Law, but...)
