Does anyone have a source for any of the above box car kits or RTR?Armand Premo

There are multiple videos on-line (such as YouTube) that show some of the 3D printers in action. At least those the average model railroader might think about buying for home use.

A good "vendor" probably will never show at a Model RR meet as the chances of making multiple sales is probably remote.

Granted the videos might not show model railroad stuff being "printed." You will see the level of detail. You'll also see the time required.

Yes, some vendors have been known to print a file if you go to a seminar or sales office- NOT complicated files. They want files that are simple (not a fret of multiple parts either) and do not take hours to produce. Also call them beforehand and ask what type of file type they require. And expect you "test" to be passed around if you go to a seminar- they are there to make sales not parts for model railroaders.

Finally, if a service group is having trouble producing levels of detail (Shapeways reduced the level they provide) - remember they are using a commercial grade machine and that costs way more than what you probably want to spend. Heck, it might be cheaper to sell out of HO and shift into a Garden Railway if you want a cheaper 3D printer.

BTW, I've created parts for N scale so I've experimented with a few machines and software packages.

Bill,



No doubt it would. However, I don't see any way we will have the bugs all
worked out in time to support either event, especially since we just reached
agreement that we won't be able to take our version to the Industry show for
a demonstration later this year. I will say that it's very encouraging when
you start to see how well it prints flat raised details. That's the main
reason for continuing to push the project. There are some items I want for
loads that I'll never see any other way.



Like you, I've got a book to complete, and still have a 50 hour /week job,
and a few other things requiring a lot of my time. Sorry.

It could very cool to have someone demo one of these machines at Naperville
and Cocoa Beach.

A work colleague, his son and I have been working since last February on
using a Makerbot to print HO scale freightcars. The original machine

worked

great until the car was 65-75% printed then the printer head would
consistently wipe or smear the molten plastic. We used the ABS ribbon to
print.



We have since been in numerous re-design phases to address the issues of
ensuring that repetitive motions are the same hour after hour, of
under-cooling and the heat build-up phases of the printer heads. Then

there

were sag problems due to wear and weigh of the components.



Slowly but surely the network of designers that are developing the

"printer

bots" are solving the various problems as they arise, but I still believe
most of what we would like to do and the models we'd like to print are

some

way in the future.



I would suggest you Google "printer bots" etc as I believe there is an
industry show very soon where most of the developers will be showing their
creations. You can learn a lot about the capabilities and if you pay
attention, the weaknesses, of the various machines being shown at these
shows.



If you happen to have the 3D CAD drawing of a couple of components, I
believe you will find that some of the developers will do a quick

print-out

for you as a demo at the show. Check several vendors and you could have

the

bases for making a determination of what or whether to buy, or who may
actually be able to print off short runs for you in the future.

Has anyone had any experience with the MakerBot company's series of

desktop

3D printer? Their first was the Thing-O-Matic. Their latest is The
ReplicatorT. It was at the Consumer Electronics Show (CES) and costs
$1,749.00. It can accept any 3D model but you run it through this compiler
type program that ReplicatorG uses something called Skeinforge to generate
the Gcode for your prints. This "slices" the design into each layer. There
were some discussions about the resolution. The Skeinforge can set the
finest resolution the machine can produce or something less. I believe

like

any printer, the higher the resolution, the longer it takes. Time is money
and your commercial outfits don't want to have long production times. You
can print in either ABS (what LegoR is made of) or PLA (a bio-material

made

from corn). The website is www.Makerbot.com . I'm saving my paper route
moneyto get one. I've been following MakerBot for a while. The

Thing-O-Matic

was $2500 and now the more capable Replciator is $1749. One of the really
nice things is that they advocate open source and shareware. You can post
your designs for anyone to download and use or improve or both! By the

time

I have the $1749, they'll probably have an even more capable model for

less.

Isn't progress great! I will always be a kit builder and the opportunity

to

make unavailable parts true to the prototype is very exciting.

Scott,

The easiest thing to do is Google "rapid prototyping" or "3D printing"

and

you'll probably get the same list I had. Make sure you read their blurbs

to

figure out which ones have the high-res equipment and do one-off

prototypes.

Memory fails me on this point, but it seemed like $150 was basically a

setup charge, then you paid per each. I may have that wrong. Good luck and
let us know if you find a place.

----- Original Message -----

There are online service bureaus for 3D printing, most with an

automated price quote feature: send them the file, they send you a price.
Seems like most of them have a >$150 minimum charge. If you're producing a
model for retail sales, that could be worth the price, but for a couple of
one-offs, no-go.

Bob, I would be willing to pay $150.00 for as many parts as that would

buy, figuring that I could sell the surplus. Could you provide some

company

names that fit your description?
