Yes, it changed about a hundred years ago and has not change significantly
since then.


Actually, it has changed quite a bit. Different alloys, and something
called Glare which sandwiched aluminium/composites which yields
competitive weight/strength ratio to pure composites.

Glare is one of the things that made the Airbus A380 possible for instance.


Glare is 30 years old and has nothing to do with the production of aluminum
metal or 3D printing.

Aluminum alloys were first standardised in the 1930's and haven't changed much
since the 1950's


That's why there are all those aluminum alloy patents in the
1980s-1990s?

Well, lots of people *do* make bread and biscuits; and a series about baking was
one of the most popular UK programs for some time.


There was a fad for affordable automatic breadmakers in the nineties.
I'm happy enough with cheap factory bread, but I offered that my wife
might want one. She didn't.

I haven't heard much about them lately. Perhaps shrunken kitchens
don't have the counter space for single-use devices.

Baking bread or making biscuits from scratch is a time consuming, labor

and hitting "print" on the 3D printer is as difficult, but I guess
that's my opinion.

I can see a few, very few, people printing junk jewelry, mostly teenage
girls.

Perhaps, but have you been to a craft store in the last 5 years?
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.

Jeff

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.

Just as PCs made prototypes *faster* and easier to design. Rather
revolutionary. Really.

Actually real engineering companies were using CAD software well before
there was such a thing as a PC. Really.

If you define "real engineering companies" as those who could afford
mainframes, sure. Everyone else was using rubylith. Even the IC
guys.

Ever heard of the PDP-8 or the HP CAD workstations that were common well
before the PC?


So no one really used Rubylith? IOW, nonsense.


Not what I said.


The point is that CAD on minicomputers was very minimal. It was the
domain of the mainframe. Rubylith was the tool of choice for the
electronics industry.

I think you need to find a better insult - "techno nerd" is a bit tautologous -

Watching is not making.

As I keep, apparently, having to explain - I am talking about *mature*
fabrication technology - something capable of working with multiple materials,
and able to fabricate something at the push of a button more quickly than
driving to buy it, and more cheaply.


Not going to happen.

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.

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?

So you think that after everyone has a 3D printer, the world will end?
Are you some sort of 3D Rastafarian, or something?

I think the likelyhood of everyone having a 3D printer is quite remote.

But that's the point of this thread.

That was one of my points.

The post that started all this was claiming people would be printing
everything at home including cars; utter nonsense.


You seem to think I'm disagreeing with you.


That the post that started all this was claiming people would be printing
everything at home including cars?


That wasn't my claim! I've been arguing on your side of that silly
proposition.

I don't see you saying anything about the post that started all this.


You're not looking.

But let me put it another way.... If 3D printers are the "next
thing", are you saying that there can't be any "next, next thing"? The
world ends after "next"?

3D printers are over 30 years old.

"The world ends" is babble.


Let me make this simple for the simple. If 3D printers are "the next
thing". Why is there not another "thing" beyond "the next thing"? End
of the world?


3D printers are an old thing.


Woooosssshhhh!

Are you saying we will have Star Trek replicators?


Do pay attention. Wow!

Do you know the meaning of the word "most"?

driving to buy it, and more cheaply.


In other words, a Star Trek replicator which doesn't exist and likely will
never exist.
