2mmFS 3D Printing - GWR Outside Framed Van (Part 3)

Today I received the printed up models of my GWR Outside Framed Van from Shapeways.

 

I am really pleased with the results (photos below). I had ordered 3 of the little chaps, one of which looks a bit rough on one side (and is in the ultrasonic cleaner as I took the photos of the other 2). Hopefully, it might look better after half an hour or so in there.

The plan now is to scratchbuild some underframes for these vans (as they are a scale 15'6" long and the 2mmSA doesn't seem to do underframes of this length). In my parts box, I have some old Colin Waite compensated W Irons which I will use (without bothering to build in the compensation), the solebars I will form from some plain metal strip with wire soldered along the edge to hopefully represent the "bulb section solebars" of this type of vehicle. For the roof, I will roll a rectangle of 10thou nickel silver to the appropriate profile.

 

According to Atkins, Beard, Hyde & Touret, these vans were built from the 1860's to 1886. The earliest would have had wooden underframes, later ones receiving bulb-section and channel underframes. The early ones would have been fitted with grease axleboxes, and later some would probably have received the OK Oil axleboxes. The photos I have of the prototype show single sided hand brake.

Excellent stuff, and well worth clicking on the images for an enlargement of the fine detail...

Look nice. I found they were easier to see with a coat of paint. I chose black, which didn't make them any easier to photograph. I can see myself adding some of these to my shapeways order, which will now come to a small fortune.

Ian, can you give some sample costings?

 

There are several methods, and some are more expensive

than others with powder etc..

Thanks for the comments guys.

 

I was reluctant to cover them in paint until I had the chassis built (the detail is very fine and I would hate to lose it under more than one coat of paint).

 

Dazzler Fan,

Following a concensus of opinion, I had these printed up in FUD (Frosted Ultra Detail) which seems to be the preferred medium, the cost for the 3 vans (including postage) came to about £28. I have since learnt however that I could have put 3 models in a single STL file as Shapeways apply a 5 euro surcharge for FUD models, so could have saved 10 euros.

 

I am currently working up further models for a W2 Outside Framed Cattle Wagon, and an Outside Framed Brake Van (AA16). Next time I will include as many of each that I want in a single file which should hopeully reduce the cost for these.

 

It should be said that of the 3 vans that I have received, one side of one of them is considerably rougher than the the rest, so I think that the process is still a little hit and miss on the quality front.
