Looks good for parts replacement. Making molds.
I can see this used to copy handmade things and then have them
reproduced in a mold. Maybe not good for us craftsmen..

Hi Lee, all,
Well, yes and no...
The part Jay Leno was showing is Cast Iron, and, the new part should also b=
e
of a similar composition Cast Iron, and not something 'machined' from some
'billet' Steel.
Mr. Leno kept talkiing about 'Machinsists', who are usually the last people
on Earth one would ever resort to for any Old Car 'part' related issues,
since they will almost certainly screw things up every time, in every way
possible, and rip you off as well for ridiculous primadonna jive charges.
Too, if the plastic rendering were to be intended for use as a Pattern in a
Casting Mold, it would have to anticipate the shrinkage of the Iron in
occupying more room when Molten than it will in cooling or cold, and, be
that much larger than the old Part is...and, possibly have some Draft added
with Puddy or Epoxy or something, for the piece to be drawn from the Mold
Halves.
This is called 'Shrink Rate', and 'Draft', and both are necessary to respec=
t
or to calculate when making Patterns for traditional methods of Sand Flask
Casting of Metals, or, most Metals anyway, and, Iron, definitely.
I imagine the Computer could be programed to have options for increasing
proportionately, according to standard formula, for the pattern to be 'so
much' larger than the original, depending on the Metal or alloy which is
intended to be used...and or to add necessary Draft to salient areas.
All in all, I would rather see the part Brazed as a repair in this
application, where, it would probably be fine for the next few hundred year=
s
anyway, if not for-ever, since it slides up and down in a captive Keyway,
and is not in a flexing mode of stress when in use.
Brazing it would probably be just fine, and a lot less hassle.
Another good repair, would be to 'Vee' out the Crack, on both sides,
stabalize the two halves of the Part, slowly heat to a cherry 'Red', and Ar=
c
Weld using material of similar composition, Band Sawed from whatever scrap,
into thin 'sticks', and, to allow a very slow cooling.
This would probably be the ideal repair, for that part.
If a proper duplicate Part were needed instead of the broken one being
repaired, I would rather a Mahagony Pattern were to be made by any able
Pattern Maker, and, for it to be used instead of the plastic rendering the
Computer Scanner arrangement had offered.
Far as that goes...
Phil

Not only that, Mike, but some hospitals are also using it to duplicate
plastic parts for trauma victims, such as skull
plates, cartilage for bone and joint reconstructions, etc.
Universities doing archaeological research (paleontology) are using it
to help reconstruct missing pieces of skeletons
for 3-D modelling of extinct species.
Very cool technology. I wish I had the justification for buying such a
gizmo. It would be a lot of fun to use.
Best,

You realize that that is done already, right? Also, you would still need to
go to a machinist (craftsman) to have the actual part made. This is amazing
because it appears to be relatively inexpensive, is 'Merican made and is
very useful technology. I am sure that the 3d Printer is much more expensiv=

Actually, no it hasn't. Machinist make "machined" objects. This
scanner and printer can capture every nuance of an object. Actually,
I see its best use in the museum and archeology.

The Dimension uPrint Personal 3D printer goes for $15,000.00 They

I would hope so. This seems like exactly the sort
of thing that a computer could do quite readily.
Scaling up to allow for shrinkage when replicating
old parts by hand has always been a bugaboo,
but a natural for computerized fabrication. I love
handwork, but for this, it ain't the best way, for sure.
>
> Brazing it would probably be just fine, and a lot less hassle.
Have the agree with Phil on this one. I have brazed
old parts that have kept on working for years. (Used
some JB weld, too, but not on any hi-temp/hi-stress
parts!)
The new 3-D 'printer' technology is amazing, and
I tried hard in grad school to think up a project
that would justify its use, as the engineering
department was rumored to have one available.
Never did come up with the kick-ass idea, but
still thinking.
Just as with any material, you have to ask whether
the idea is really best executed in that medium or not.
I see a lot of clay that also makes me ask "why clay?"
Just having it on hand isn't a good answer if you want
real excellence.

I love a beautiful handmade template, but in terms
of plain functionality, I like the dimensional stability
of plastic.
As for the video, it was the in-situ integral fabrication
of moving parts that really impressed me the most!
Don't know how that could be of use for something
that needs to be cast in metal later, but if plastic is the
end product, that property alone is a compelling reason
to choose this method.
And I don't think anything that addresses issues of
making and fabrication is ever really off-topic.

I saw a video a year or two ago of a 3D printer that built the model
out of layer upon layer of kaolin slip which could then be fired. One
of the "comments" posted on the page was just wonderful. The

crappy ashtray."
All the best.

Yes I do.
All I have to do is look in my mouth at my latest dental crown!
This happened to be a replacement crown for an old, damaged one, but
the procedure is the same for a new one. Before removing the old
crown, my dentist stuck a scanner in my mouth. Then, after grinding
down the tooth, scanned the remaining "stump."
So two scans--one for the outer surface of the new crown and one for
the inner one.
An hour later he popped in the newly milled crown (some sort of
ceramicy, plasticy material I suppose)--perfect fit!
This procedure saves him making two office visits for each crown, but
(at least for now as he's learning to use it) takes more of his
time. That is, more costly. And the system, though smaller and less
accomplished than that in the Leno video, still must have been pretty
expensive.

I think that one thing this would be great for is making (mechanical)
prototypes.
Sometimes you need to see or feel how things go together before you
can make them better. For those of us backyard inventors this would be
an ideal solution (once the price comes down a bit more!).
Obviously this is not an "artists" viewpoint, but I enjoy designing
Heath Robinson (Rube Goldberg?) type devices, and it would be cool to
actually make them, even if they were in plastic!
