Nope, silicone rubber once cured has no melting point. 300 C is the maximum temperature it can withstand before permanetly degrading. Silicone rubbers in general have poor resistance to steam, super heated water, oils, fuels and solvents. Silicone rubbers would be impractical to 3D print due the the chemistry. In any case there are ceramic-based insulators that can withstand in the range of 500C http://www.ceramawire.com/technical-information.shtml And are just as impractical to 3D print. Well, except that there are outfits that are 3-D printing ceramics NOW, so perhaps not so impractical after all. -- "Some people get lost in thought because it's such unfamiliar territory." --G.

Great, yet another techno nerd weenie who spends way too much time watching Star Trek reruns. Bless. It's almost as though you imagine anyone give even the tinest of ****s what you think. You're reading his posts and answering. Apparently _you_ give at least the tiniest **** what he thinks. Good point, but since I think he's wrong about everything, it's not really about him, more about the wider points being made. |

I suspect 3D printing at home will be as successful as the personal computer. I mean everyone knows they're useless at home and we'll only need a few major mainframes. Personal computer use in the home is dropping with increased use of smart phones for those important tasks such as posting on twitter and facebook. The original point was that the original "personal computers" were hideously expensive, very hard to use, and didn't do a whole lot. There absolutely were a lot of people who said "I'll never need one of those" back in the early 1980s. Yet they can be found (in desktop or laptop form) in the vast majority of houses in the US because the price dropped, they became much easier to use, and they could do a lot more (i.e. high speed Internet versus acoustic modems and BBSes), Besides, smart phones prove the point AGAIN! When the original Apple iPhone came out, it didn't have it's "killer app" which was the App Store, so the orignal wasn't terribly functional. On top of that, cell data service at the time was slow, slow, slow, so even surfing the Internet was painful with these new "smart phones". But again, the majority of phones I see today are now "smart phones". They're cheaper, more functional (more apps), and the cell data networks are quite good these days. New technologies keep getting cheaper and more accessible for individuals to use all the time! It's a pretty safe bet that the very same thing will happen with 3D printing. Which reminds me, I need to tell my friends who own 3D printers and printing parts to fix things at homes, tools, and tool holders and all manner of things that I never would have thought of myself that they're wrong and no one will effectively use a 3D printer at home. How many people do you know that own 3D printers? That's today. We're talking about the trending of the technology. I know about a dozen people that own things like welders, milling machines, drill presses, and lathes but no one that owns a 3D printer. Honestly, it's pretty damn presumptuous to claim that there's no future to 3D printing at home. I suspect 10-20 years from now we'll be laughing at such claims. Like computers, it will continue to improve. It'll get faster, more capable, capable of using more materials, etc. Since no one in this thread has made that claim, your post is nonsense. That sure as hell seems to be what you're arguing. Jeff -- All opinions posted by me on Usenet News are mine, and mine alone.

New technologies keep getting cheaper and more accessible for individuals to use all the time! It's a pretty safe bet that the very same thing will happen with 3D printing. New technologies will not make aluminum or plastic cheaper. Printing speed is limited by basic physics. Most people can not be bothered to make their own bread or biscuits on equipment they already own. 3D printers for home use are already less than $200; how many people do you know that have one? Which reminds me, I need to tell my friends who own 3D printers and printing parts to fix things at homes, tools, and tool holders and all manner of things that I never would have thought of myself that they're wrong and no one will effectively use a 3D printer at home.

The trending of the technology for home use is anybodies guess; my guess is that it will be trivial and hobbiests just like the people that own machinery like drill presses and milling machines.
