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

And are just as impractical to 3D print.

They've been selling commercial 2d robotic cutters for many years that
are about the size of an ink-jet printer. The stupid thing shows
absolutely no sign of stopping even though the "cartridges" which
contain the cutting patterns are DRM protected and *very* expensive.
They are mostly used by people who like to do scrap books, but others
use them for making their own greeting cards and etc.

In those same craft stores is a large jewelery making section. Those
"memory bracelets" people make are a hot thing because "every item on it
represents a memory". In other words, these things are already highly
customized.

So, I wouldn't discount the notion that the crafts stores might start
selling very small 3d metal printers for making little dangling things
for jewelery (memory bracelets, necklace charms, and etc.) since this
would drop right into the market-space. They would only need to print
at most 3" x 3" x 3" to cover 99% of the jewelery market.

That same metal printer would sell "big league" at game stores where
custom cast characters for board games are already a huge market. In
other words Dungeons and Dragons, Warhammer 40k, and etc. Even if an
individual player wouldn't want one, every damn game store on the planet
would want at least a couple.

By those standards black powder firearms will take over the firearms world.

I'm not saying there is not and will not be a bunch of niche users of
3D printing.

What I am saying is that 3D printing is not going to be the next industrial
revolution.

Personal 3D printing won't be the next industrial revolution. 3D
printing is already revolutionizing engineering.

Nonsense.

3D printing is simply making some prototypes easiery to make.

CAD software has to a certain extent revolutionized engineering, but that
is very old news.

I suspect 3D printing at home will be as successful as the personal

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.

Banking and Amazon, too. Though that isn't to say that there isn't
anything beyond the 3D printer.

Like what, a 4D printer?

Of course the ultimate would be a genuine Star Trek replicator:

"Computer a 1968 Gibson Les Paul Custom and a cup of Earl Grey, hot."

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?

I know of none but we have several at work. One of my cow-orkers was
going to buy one and use it as a side business but he figured out that
it made no business sense.

Could that be because custom machine shops have real industrial grade
3D printers?

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.

3D printing actually is quite useful as part of a bespoke
jewellery-making process. You design a 3D model using a CAD program
such as Jewelsmith, print a positive, then use investment casting to
produce a one-time mold, which is used to mold precious metal.

No one said that 3D printers weren't useful. The argument is whether
they'll take over traditional manufacturing. That is, everyone makes
what they need at home, on their magic printer.


That is NOT the argument for most of us. The argument is whether they
are 'game changing' or not. Jimp the Chimp argues that they are niche
applications at best and will never be anything else. The
counter-argument is when you start listing niches and potential
niches, pretty soon you're changing the game in a lot of places.
