Printed on an Objet Connex500 printer, Boston's Fenway Park is about 1/200th scale (3 ft x 5 ft), includes 40 separate printed sections, 22 builds and, when put together, weighs about 105 lb. Check out a video here. (Source: Objet)
I think that's where we are heading, Chuck. Not overnight, of course. But 3D printing has made some dramatic turns in terms of price reductions and capabilities this year and the scenario you outline is where most experts see the broadest impact. Just think back three or four years ago--most people didn't carry smart phones. Now most do. With certain technologies, the tide can turn pretty quickly and I think 3D printing has that potential.
The automotive taillight is an interesting application. I wonder if we can foresee a day when dealerships and garages will be able to make plastic parts on site, thereby reducing inventory for the parts department.
@ervin: All good points. There is a steady stream of boat and automotive makers already using 3D printing to produce prototype parts and in some limited run cases, production parts. It seems to be prevalent in the racing industry where you're really optimizing and many of these things are one-offs or close to it.
Beth, excellent article and to think, David Deckard started it all with stereolighography.He was a graduate student in those days but launched a new technology that is now called "additive manufacturing.Several months ago I wrote a paper on that manufacturing technique for PDHonline.org.There are several processes that fall under that description.These are as follows:
Selective Laser Sintering
Fused Deposition Modeling
Laminated Object Manufacturing
Shaped Deposition Manufacturing.
All are fascinating and save countless hours when prototyping a component.Engineers always like to "kick the tires" prior to committing to a specific design and these prototyping techniques allows for just that.Again—great piece.
I agree, smith120. More so than any other subject we write about here at Design News, these pictures really do tell the story. Each time I click through the photos, I end up saying, "They built that with a 3D printer?"
I really enjoy the 3D articles especially when pictures are provided. It is amazing the different things that are created using the 3D printers. I'm glad prices are decreasing this opens some new doors for lots of small companies.
I have been following the posts about 3D printing and it is interesting. It only stands to reason that once the platform is designed and standardized that material scientists will get on board and find ways to meet your manufacturing needs. It's all a supply and demand curve. With 3D printers demanding more options out there and easier to attain manufacturers will get creative quickly. I have heard that marine and automotive are already considering of 3D printing some parts for low production numbers. I don't see this being ideal for any mass produced part since injection molding will still rule that field. Also keep in mind that some of the Composite material airplanes today use special made 3D printers. So if one of the most controlled transportation industries in the world is allowed to use 3D printers I don't see why other applications cannot be allowed?
I have been a user of various RP technologies for over 10 years, and it can be invaluable in getting evaluation versions in your hands, even functional prototypes are now the norm given all of the material choices available. I recall a few years back a webinar with a guy who was a big proponent of the future of consumer-level RP machinery. He invisioned people having consumer versions of 3D printers at home to allow them to download 3D files directly from manufacturers so that they could build their own replacement parts for various consumer products that had failed. I think that is still a ways off, but an interesting idea, nontheless.
It is fast becoming that mix of fun and wacky (printing chocolate, printing food, printing shoes and furniture) and highly functional (printing UAVs and small machine prototypes). I think Chuck's point about ideas percolating is also critical. People are predisposed to experimenting with this technology and putting it to different uses. Once they do, the enthusiasm is viral, spawing more and more applications and pushing the use-case envelope even further.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
