Date of prediction: 2013-07-22

A short-term prediction regarding the 3D printer market:

»These patents cover a technology known as “laser sintering,” the lowest-cost 3D printing technology. Because of its high resolution in all three dimensions, laser sintering can produce goods that can be sold as finished products.
Once the key patents on 3D printing via laser sintering expire, we could see huge drop in the price of these devices, says Scott. This isn’t just idle speculation; when the key patents expired on a more primitive form of 3D printing, known as fused deposition modeling, the result was an explosion of open-source FDM printers that eventually led to iconic home and hobbyist 3D printer manufacturer Makerbot.«
