Gartner analyst Pete Basiliere is quoted in Business Week as estimating that by 2011 there will be 300,000 3D printers "on the market". Not sure what's meant by that wording - 300,000 total sold, or 300,000 in year? To put it in perspective, the same story gives Terry Wohler's estimate that just over 3000 were sold in 2007. So a hundred-fold increase in just 4 years? I thought I was bullish on the technology.
By the way, I heard that one of the 3D printing companies was spreading rumors that Desktop Factory has "closed its doors". Well, I was down there today and walked through the door. It's true you do have to ring a bell, then they let you in, but they are working away and continuing to make good progress.
