3-D Printed Finished Goods Are No Jokehttp://www.fool.com/investing/general/2013/11/22/3-d-printed-finished-goods-are-no-joke.aspx Steve Heller

Additive manufacturing authority Wohlers Associates has come out with a note saying how it expects the 3-D printed finished goods market to "far surpass" the 3-D printed prototyping market. Driven by continued advancements in 3-D printing technology, investors can look forward to 3-D printing playing a bigger role in finished goods manufacturing.
A growing trend
By utilizing a 3-D printing technology called selective laser sintering, or SLS, GE will be able to "print" the fuel nozzle as one finished part, capable of withstanding 2,400 degrees Fahrenheit. The same nozzle made with conventional manufacturing methods would have to be made in 20 parts and would tie up additional resources during the assembly process. Ultimately, GE hopes to put out 45,000 fuel nozzles a year from its 3-D printing operations, but it isn't expected to reach this goal for a number of years.
Due to capacity constraints, GE would have to purchase 60-70 current-generation printers, which can cost upwards of $1 million per device, in order to achieve its target output. Instead, GE has pledged to invest "tens of millions" of dollars toward building out the technology supply chain so that next-generation 3-D printers can handle three to four times the capacity. In other words, the next-generation of industrial 3-D printers will likely be better suited and more cost effective to handle the scale of an industrial giant like GE.
Additionally, neither voxeljet's (NYSE: VJET) nor ExOne's (NASDAQ: XONE) 3-D printing technology is well-suited for GE's current fuel nozzle needs because neither employ the use of SLS technology. Instead, both companies use a bonding agent to adhere layers of material together, as opposed to a laser that fuses layers together. Investors shouldn't take this to mean that voxeljet or ExOne won't be playing a big role in the future of finished parts 3-D printing. The reason is that both are heavily reliant on printing with sand on an industrial scale, which is an
