Hi Ken. Did you make that coach.
How is it made ? Is plastic stock feed into a printer and the laser cuts the detail ?

hi frank,i wish,its done by a shop,you take the plans in and this is what 3d printer churns out,not cheap at the moment,but costs are coming down by the day ken
all these photos were used to show what 3d printers can do now

Those wooden coaches look great. The possibilities will be endless with this technology. Take a look at this Woodruff Sleeping Car from Eight Wheeler Models.

I have hi-res images of the detail, but I can't upload them without reducing them too much.

Holy cow. Holy smoking cow. As it is well known, manufacturers have
to make so many thousands of any given unit to be able to get a return
on investment. Soon comes the day when I can put in an order for some
odd ball N de M shop built F7 hybrid creature and clip it onto my Athearn chassis.
What are the limits of the technology as it stands now? If one wanted some
complex Shay with all the piping and pistons, is that doable?

really hoping someone does a P30ch shell....all the overland ones I see are $700+ 
just me Ray... and just because I have Tyco doesn't mean I am not a model railroader

When I started working with the 3D printing process about 15 years ago, the resolution was poor and the jaggies on curved surfaces were about a millimeter and needed a lot of sanding or puttying. Now they can grow things like these 6 wheel trucks for the Woodruff car, and the process will only improve.

I think stuff like this might be the future of model railroading in general. I mean, kids in this generation (including me ) love electronics and designing things on computers and 3d printing fits in that category perfectly. I mean look at those. These might actually be the type of things that will save model railroading in general.

Those trucks are a work of art. Very impressive.

3D printing is very complex. I have had to relearn CAD in order to make my printer to work. Not an easy task at my age. One thing you have to know is that there are potential legal problems concerning copyright and patent issues. If you print parts for your own repairs you are OK just don't try to sell them on the web for profit. There are plenty of forum out there that deal with 3D printing and It can be overwhelming the info and challenges out there.

I see you must use Shapeways... I've seen those paper wheel inserts available on there. I guess they fit rather nicely in P2K wheelsets! However, that truck looks like "frosted ultra detail" given the detail on the leaf and coil springs, which I've heard is rather brittle - how did you install the wheelsets? Is it more flexible than I thought?
If so, my first idea would be andrews trucks cut out for roller bearings - someone already has cutout archbars on Shapeways, and Rapido just released their cutout bettendorfs (although they're rather expensive, it might be cheaper to 3D print your own!).

Connor, that's not my work. Check the link above for Eight-Wheeler Models.
I don't know how brittle current materials are, but SLA resin when I was working with it 10 years ago was quite brittle, so we only used grown parts as molding masters.
Since these wheelsets have plastic axles, my guess is they bend them instead of the frames.

I haven't tried it yet but I'm tempted. Small 3D printers are getting to be fairly inexpensive and with good resolution too.

I have a 3d printer and am still learning how to use it. The hardest part is learning the CAD program to develop your object file (new tech language here) for the printer. Simple 3D programs like GOOGLE SKETCH UP or BLENDER (both are open source freeware programs) and can do reasonably good work and are easier to learn. For more complex work I use AUTOCAD 2014.
My REPRAP printer does OK with ABS filament but is limited to small parts as the heated build plate keeps the object soft and large pieces tend to distort. I am going to try PLA filament as it doesn't need a heated bed and is made fron corn based sugars.
My advice to anyone wanting to try this had better be prepared to spend a LOT of time on this new hobby of yours.

So, this brings up a good question, I'd like a P30ch shell, I know model railroader mag had a drawing of one...so how hard would it be to scan the drawings and render it for 3d printing?
I'm having a thought....

Leo - your printer "builds" the part, as opposed to cutting it from a larger piece of stock? And you can watch this happen in front of your eyes?

Yes it builds in layers using a fused filament fabrication process. the plastic comes on a spool like wire and is fed through a heated nozzle in the print head. ( kind of like squeezing toothpaste out of the tube) It then moves(the print head) back and forth on the X and Y axis and deposits a drop of plastic where the program tells it to.(just like a paper printer) Then it moves to the Z axis and moves the print head up ( some printers move the build bed down instead) and the cycle begins again. This brings up 2 constaints : total build volume and time. You can watch it building your part but it takes time ( kind of like watching paint dry ) My boiler fronts take about an hour start to finish while my cabs take up to 6 hours. The more of the XYZ volume you use the longer it will take
rgcw5
You can scan in your drawing to your computer ( JPEG format OK Bitmaped better) then import it to your CAD program where you assemble the sides and ends and eliminate the detail elements. However, you will have a rendering of a solid model. you will have to remove the inside material and determine the postion and shape of any mounting lugs. Then you can print if you have a printer with a large enough build volume.
You can do one of two options. one search the various repositories on the web for one that already exists ( most authors only want you to attribute them, and are free) or two send a scanned copy to a company like SHAPEWAYS and get a quote.
Since MR clearly states that the plans are for personal use and not for commercial with out permission you will be OK legaly.

can it grow the 6 wheel trucks for the Tyco triple dome tank cars or cranes?
We all could use a bunch I'm sure
