3D Printer?

I have used Shapeways to make custom windows for buildings and custom baggage doors.  The windows were expensive because I needed fine detail for muntins.  The baggage doors were cheap.  There is definitely a learning curve in using 3D software.  However, Shapeways offers a 2D to 3D service that works well for things like doors.

My son and I share a Makerbot 2.0.  I've downloaded files and made a few people, nothing else so far.

I thought maybe someone would use one to make the extension couplers for the Lionel shays that would allow operation on 031 curves.

It was easier just to make the part by hand with normal power tools and such, using the photos posted on the threads about the problem.  But I understand your point.  It is so difficult, at least for me, to use the software that designs the control to make something, that so far I have only printed files I download.

And a hockey puck.  I managed to operate the software to build a disk -  and print a sort of hockey hockey puck!

You have to also remember that the parts are plastic, and not terribly strong construction.

I have been following the 3-D printer story from day one. I have had a laser cutter for 14 years now.....so new tech is always on my radar.

3-D printing has a number of limitations.

GOOD machines are still costly and have a steep learning curve....so does the software you need to master in order to make your own parts.

The media is costly vs the amount used to make a part. Lee is right that many items can be made cheaper and faster by hand than 3-D printer.

3-D printers have a place in the hobby but not to the extent some folks and most of the mass media think......IMHO only.

PS....many other threads on 3-D here on OGR forum.

I have no doubt that 20 years from now, 3-D printers will be better, cheaper, and much easy to use than today's.  But for now, methods I learned from my father and taught myself all along will be what I stick with for making parts, bashing locos and such.  Not being negative (I bought the Makerbot after all), just realistic.  

I am about to experiment with this - not on my own but through someone who has used 3D printing to make N and HO parts. The parts in question are tender shells for models that Lionel and MTH don't (and realistically probably won't ever) produce. Too soon to say how this project will pan out but I'll report back on the finished products.

I have also thought about 3D printing for interior detailing in passenger cars but that idea is on hold pending the results of the above.

I'm with you Lee.  While the technology is pretty amazing, I think it's going to be some time before it's mainstream.  I'd love to have one, but I just don't see that I'd really have a practical use for it.

The local MicroCenter has several models for sale. They have made a number of objects and although they are made using some type of plastic they seem rather sturdy.

I had a thought about taking the part and going there to see if they would be willing to make a copy of it for me.

When I worked at CertainTeed we used what was referred to as "rapid prototype" to design window profiles but the finished prototype was very fragile. I don't get the impression that the current 3D printers produce a more substantial product.

Also, I thought I saw a segment on TV some years back about a 3D copier. They actually made and operable adjustable wrench that did work. I think they just put an actual wrench on the copier surface and the machine did the rest.

Anyone remember that?
