Last evening I went to a beginners class on 3D printing. The class was using a program by Autodesk called " 123D Design " to create files for 3D printing. Looks like a pretty good program especially considering that the program is free.

The local library will print a 3D object for free as long as it does not take more than 5 hours to print and you accept whatever color they are using.

Looks like it would be easy to print up a pattern to use in casting parts.

If you search on 123D Design , you will find some additional programs to use for things as scanning an object and creating a duplicate by 3 D printing.

So is anyone doing anything with 3D printing?

I have one a three color head. There are some design flaws in this
model. I'm going to re-engineer it and depopulate to two heads and
if required one head. Three heads have fist size servo motors and
they move as one. It can rock a metal tubing table easily.

I have it on four concrete piers - and a 4" sheet of sandstone.
The back up to the table.

It is a work in progress, and I just got a new OS and design tools.

I've been moving into my new office and getting my engraver sorted out.

I sent a email to some of the people at the museum about 3D printing and got a reply asking if one can 3D print 3D autocad drawings. A quick search found a number of sites that told how simple it was to do that. Looks like you could go the other direction and import a .stl file into Autocad.

You can glean some info from Shapeways website too:

If you get something developed you would like to sell they can do that
too. Edward Falk who sometimes posts here (haven't seen him lately) has

Pure logic would tell me that jon_banquer, Ed Huntress or Joe Gwinn are (or might as well be), so I'd ask them specifically. As for me, I don't personally know (because I'm more into high and low voltage wiring and 18w truck driving, etc...)

Lots of members of my LinkedIn group CADCAM Technology Leaders are heavily involved with 3D printing including my friend Daniel. Enjoy!

Once again the jokes on Jonathan Ball who has zero metalworking skills and no CADCAM skills. He's never recovered from the ass kicking I gave he a few years back and he's still lying face down in a gutter.

Without a doubt CADCAM will be critical. Hybrid is the future for 3D metal printing.

Actually I am interested in hearing from those doing it, but also those that have decided it is not worthwhile, and even from those that are studying it.

Since the museum has two people who know Autocad, I think they will find uses. But someone here may have some insights into ways it can be used that I would not think of. Or experiences with places that will do the printing from your file. Or experiences with building a 3D printer.

Right now I am in the learn the big picture mode. But could get into specifics if we start to use it.

I have little to offer here. My focus is on the big commercial
printers, mainly laser-sintering machines for metal.

It sounds like you're on the right track, though. A simple modeler
that produces STL files should be all you need. It's great that your
library has that machine!

Oh, and you're right, making patterns for casting is one of the
original uses for 3D printing. Also, some people use some type of wax
or plastic made for the purpose, and make investment-casting patterns.
I've never looked into it, though.

I did a little looking around. The material used for investment casting is PLA. Made from Soy Beans. The regular material gives toxic fumes when being melted out.

Early on when this stuff was being invented and the printer was a
hacked dot matrix machine under a mare's nest of tubes and cables,
late 80s maybe, I saw an experimental setup at MIT. They were printing
with glue and steel spherules. After sintering, the result was put in
a puddle of another metal (bronze? brass?) in an oven. The molten
metal was drawn into the interstices by osmosis. I don't think it was
a very successful technique but I haven't kept up on the subject.

I've heard that complex pattern-welded billets are being made by 3D
printing differeing steel grains, sintering, then fusing at a welding
heat and/or under a press. Didn't get the details.

Ball, I admit that my job today certainly doesn't have as much to do with metal working as it may have in the past. But you? Looking at your posts, you have about as much to do with RCM as a cat does in a dog pound.

Oh, man, that should be great for making machined-billet brake pedal
arms and such, for people you wish wouldn't show up for work in the
morning!

Speaking of exotic metals, here's one from Boeing that they describe
as he "Lightest. Metal. Ever." It will be appreciated by some in this
group because it's 99% air:

Back around 1980- there was a 3d printing technique
using laminated layers of paper that was big in
pattern making but CNC machining soon pushed it aside.

Today most of the metal casting using 3d printing is
in the jewelry making business. Not much for
foundry casting.

Z-corp makes a 3d printer that prints objects made of
sand.
Its used for making sand molds and cores for
making prototype or one-off castings.

If you get it printed in PLA - the low level plastic can be dissolved
out and anything left burnt in mold generation. Or if you are into
green sand directly Make the part.

The Ring industry is into this exact function. They make blanks with
details that are refined and polished up pretty.

ABS and Nylon are the standard other than PLA.

My small hand unit uses ABS and PLA and wood... I got it going tonight.
My birthday present (early naturally).

3Ddoodler

Seems useable and even for patching other designs as the tip melts and
it is like filling with putty so voids can be filled and sanded over.

It also makes 2d and some wire frame or nearly shell 3D.

GM has built cars with large 3D printers. Engines and all.
They can get a new curve or bend or fit the next day.
