Subject: Re: [Phys-l] 3-d printer
Very real. These things are becoming widely available akin to the way
laser printers became common 20y ago.
Economic commentary discussed in "Print me a Stradivarius" etc from The
Economist:

and a more practical discussion of actual 3D printing tech in final
parts (for aircraft):

Thanks for the quick reply. My high school students, their
student/teacher/parents e-mail group were very interested in this whole
topic also and I am passing along the info I received from you and the
others. The cost problem is one of our unanswered questions that you
just cleared up. Honestly, no one in this group of about twenty
intelligent people ever heard of this before seeing this video so even
though it has been out there for years it has not been publicized very
much.

The one at TechShopRDU etc. has a pretty serious 'Materials' charge.
The cost of the machine is pretty steep too.
Ours gets used for 'one-off' prototyping of parts that will earn
their keep in other processing machines.
Some nice baubles and bangles have been made - but not cheaply.
It's nice to have such a machine available - but it is FAR from
Whichheavily used.
The LASER cutter on the other hand - is booked solid.

Ok, thanks for the info. More Questions : if this printer can
make a wrench that works and is as strong as the demonstration
shows, why don't we see whole industries built around the
technology... door knobs, locks, tools of all sorts, etc. ... or
is it just cheaper to make them on the traditional assembly line?
Is this so expensive that the cost outweighs the convenience?
hardwarebrings up the thought of a store keeping inventory... say a
store invests in a 3-d printer for a one-time investment. The_______________________________________________
proprietor can then buy one of everything and make more on the
printer instead of buying boxes of, say, wrenches at a cost
involving the price of the tool itself, plus shipping, not to
mention storage and shelf space.
