Mark,
Looks lovely! Are you making a display out of them or are they all for different uses?

Hi Joris,
There are parts for three models shown. The three models are in the early stages of development, so I am experimenting with methods and materials.
The other materials/methods I use are photoetched brass, laser cut brass and card, vac formed styrene; and fabrications in styrene, brass and timber for whitemetal spin, brass investment and urethane casting. 3D CAD is much faster and repeatable than the handmade methods which is where SW comes in 
Now if SW would print silicon moulds for urethane/resin casting, and waxes for investment casting, that would be another two areas of production I'd move to The Netherlands

Hey, neat! I haven't seen my models in that material before.

I am just too excited by this item to not share it.
It is a cow catcher from a train. The largest dimension is around 2 inches/50mm.
Usually a cowcatcher is scratchbuilt from brass, soldered together. Burnt fingers and frayed nerves 
They are just so difficult to get right with all the angles.
It is so beautiful, I am thinking about doing a whole locomotive in polished SS, I have worked out I can keep it under US$600, but it would be a mantle-piece model rather than an operational one.
The texture reminds me of some trains in New Zealand which were pulled out of a river 100 years after they were dumped there, and rebuilt, with this mottled texture on every ferrous part.

I've seen the cow catcher on the gallery a few moments ago, looks beatiful May I ask how much it costs to print such a piece? How thin are the bars?

Hello Marcus,
Thankyou.
The cow catcher is $22.00 in polished SS, $6.82 in white detail. The bars are 1mm diameter. It is very sturdy in SS.
Cheers,
Mark

Thanks for the info Good to know they'll print such large minimum detail areas.

Arrived this morning:
I ordered two of these, the other has some blemishes that will need to be filled and smoothed

Alumide is sexy
But sadly not appropriate for use as masters for moulding due to the texture. To me the texture is slightly less rough than WSF but not as smooth as the detail materials.
These will have areas picked out in metallic paints for that steampunky look.

The boiler looks great and the rivet head detail looks to show up clearly.
A couple of questions-
Approximately what diameter are the rivet heads?
what material is it?
The boiler is shown vertically in the shapeways render is this for any reason?
Simon.

Hi Simon,
The material is black detail. Transparent detail seems to be finer but I've had trouble with SW's transparent detail material still being a thick gel and thus unworkable.
Rivet heads are 0.6mm dia and stand 0.4mm proud.
I'm not sure about the model orientation. Solid Edge and Shapeways don't seem to agree on which plane is horizontal.
Hope that helps,
-Mark

I love it when it all comes together:
I'm not happy with it as a model of a train, but I am very happy with it as a proof of concept.
The only major parts not prototyped through Shapeways are the laser cut brass frames, brass axles and the soldered brass footplate.
Needs some work on clearences and bracing of the parts-both side tanks, bunker and the boiler have distorted. Some parts didn't fit so well since I had to cut them up to remove damaged sections.
But hey, looks like a steam train

WOW! Fantastic finished part. I think you should be very happy with your "proof of concept", actually very proud!
What next for you? Will we see another train model?

Thanks for the kind words Todd,
I need to redesign a few parts of this model before it is ready for low-run production as a kit.
Afterwards there will be more trains But I don't know which ones yet.
Cheers,
Mark
P.S. The 3D modelling on your website is superb!

Thanks for your kind words.
Its fun to model the stuff in a computer, but it is a totally other thing to have something you design in a computer show up on your door step! THATS JUST DARN AMAZING!

Cool Mark. Thanks for sharing this lovely craft. It would be nice if you could place it on rail road layout.

Hi guys,
I had a good day yesterday, a cup of tea and a pair of cookies. I have this neighbor who is passionate with recreation. He climbs, swim, bikes, run, and play. So I initiate a talk by introducing him a great hobby which is model trains. At first, it seems that it's not his field, but during the middle of conversation, when I said to him that, do you know that a 63 years old is still playing with this craft, then he laughed.  Before we part ways, I heard him saying, maybe I should try it.
....NOW, he's with me buying some stuff to start.

Been a while since I have posted anything,as I have been sending my files to be printed elsewhere.
I received my FUD samples today.
These are all for O scale.
Chopper/Norwegian couplers, on sprues to keep them together.
Pre assembled, yes all the parts do move, used 0.05mm minimum clearance on all shaft/hole locations.
They do need further development though-far too fine to work and not actually prototypical.
As others have found, FUD is awesome...when it works. An otherwise fantastic model spoiled by a shift in surface quality.
This image doesn't show it too well, but I am astounded by how fine the bottom flange on this chimney is.
I am happy that Shapeways offer FUD. SW lost my custom as the detail materials just weren't good enough. So FUD has brought a customer back...
