jecmontesa, thanks for the details. It's always interesting to me to find out where people were working when they worked with or came across various different technologies, especially in the earl stages. The history of ideas has always fascinated me.

Ann, I was working for Spectron Development Labs, Costa Mesa CA. Small privately held company, 50 employees founded by Chris Busch and Jim Trolinger. Was widely recognized for development of laser based instrumentation for aeronautics, combustion and other applications. SDL was sold in 1988 to Titan Systems of San Diego, a defense technology company. Jim Trolinger went on to found MetroLaser, Irvine CA, where he still is active.

jecmontesa, can you tell us what company you were working at while doing that research years ago?

Years ago, we were working on methods for producing streams of droplets with uniform size. This was the beginning of ink jet printing. We used glass nozzles with 50 micron ID and piezo-electric tubes to drive the droplet generation. With the drive set at the resonance frequency, the droplet size was very uniform. We used mostly liquid fuels, but also did make some droplet streams from liquid metals, mercury. Worked beautifully. Nice equipment, Vader!

There are actually a fair amount of body parts that have already been fabricated via 3D printing, but primarily with plastics and not metals. But I'm sure it won't be this way for long and metals will soon be a part of the process as well.

Yes, Debera, I agree. While the technology seems to be moving ahead at a fast clip it seems there is a lot more potential and it's an exciting space to watch. Who knows what will be next?

Organisations are working to on making arms thrrough 3D printing . I have read somewhere that one of the organisation have developed a 3d printed metal gun . The total components of the gun were 42 out of which 36 were 3d printed and 6 were purchased however they are not planning to sell the gun but now they are working on developing more 3d printed arms

Yes Elizebeth no doubt there is quite a lot of innovation going on in this 3d printing technology actually it is not a complete or mature technology scientist , engineers are trying to make it more mature by adding / testing the innovations. Few years from now this will definitely be the technology of future.

And defiantly this will greatly reduce the production cost of those.

far911, that's an interesting point: when a technology makes it into the movies that means even Hollywood script writers have heard of it, so it must be widespread :)

Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
GE Aviation not only plans to use 3D printing to mass-produce metal parts for its LEAP jet engine, but it's also developing a separate technology for 3D-printing metal parts used in its other engines.
The demand for solar energy around the world will grow a total of 75% by 2019, according to a new report by Lux Research. Trade disputes and policy changes, though, will complicate the picture.
Bayer MaterialScience is using CO2 to produce a precursor for high-quality polyurethane foam at its pilot plant in Leverkusen. The transition to full-scale manufacturing is expected in 2016.
