About this Product
Perhaps this goods shed of a lost railway station in southern England is not the most striking building architecturally speaking to win a contest, even 3D printing contest, (although Swanage Railway people maybe love it XD) but it's a wonderful example of the difficulties involved in the attempt to develop scale models for 3d printing with some accuracy and richness of detail.
In this case, the relevant aspect of the model is not the work done to model each of the stones of the walls texture (inner or outer), but the failures once printed.
The model was printed by Shapeways in WSF material, and only after being rejected and having to insist via email, accepting the results under my responsibility (before disposing of the official option 'Print it aniway').
The result of the printed model not only presents a disappointing aspect over other buildings printed correctly, but was rejected and marked as non-printable.
As seen in the pictures, the stones of the facade look the same as if the model would had been subjected to high temperature, the material was partially melted and after placing the model on a surface, the details would have been crushed an flattened.
I do not know exactly what was the difference compared to other similar buildings whose printing itself was successful, because I was not given any information beyond "the model could not be printed correctly", but I have not yet come to understand where the issue was.
Worst of all, is that the problem is not only with this building, but because of this failure, similar projects, with larger size buildings, have been paralyzed because I can not risk to afford the investment involving testing without any warranty, not of being able to print the model correctly, but printing it, getting a result with errors, and not knowing how to fix it.
Models with many hours of work, as this other railway modelling in British N Scale (1:148th) related sheds, http://shpws.me/qnsZ, or this http://shpws.me/pKMr, sleep the sleep of the just with their development frozen in last stage due to this issue.
The availability of a home printer as Form 1 would allow me to test at home printing on prototypes for generating perfectly printable Shapeways models, and getting off the hook these large models whose economic investment in testing makes, for the moment, unworkable
Description of the model (from Wikipedia)
Corfe Castle Railway Station Goods Shed in British N Scale (N Gauge 1/148th)
The Swanage Railway was a branch line from near Wareham, Dorset to Swanage; it opened in 1885, and the independent company that built it was amalgamated with the larger London and South Western Railway in 1886.
The passenger service was withdrawn in 1972, leaving a residual freight service over part of the line handling mineral traffic.
After the passenger closure, a heritage railway group revived part of the line; it too used the name Swanage Railway and now operates a 6-mile (9.7 km) line, which follows the route of the former line from Norden, via Corfe Castle, Harman's Cross and Herston Halt to Swanage.
