I have not found any problem with wagon chassis, possibly because I am not requiring engineering accuracy. The wheels fit OK, and work OK. Easy to modify if required. Only problem might be with the 14mm gauge ones where there is far less room to move, but again easy to modify. I offer option of better plastic for these .
I have had a problem with the large WDLR van, where one side comes out better than the other.
The track sections are odd, as I deliberately set up the designs to face same way, and each contained 3 different versions of each type of track(point, curve, straight etc), so I could compare different surface textures. I found that the points ere much tight to fit rail into , yet the rail profiles were identical. I will try some with only one point, so see if reducing flat plane size means a better machine is used.
Is there some way to force the design to be printed in way you want, not what the operator sets it to. I seem to be able to get default Shapeways picture right way round now for track, but suspect that does not match up with way it is printed in machine.
Odd thing ius it was the last item to print that seems to have had the problem. Need to check design before confirming, as file size is big, and CAD software sometimes goes crazy, and I have not noticed something moved or flipped till too late.
Narrow gauge Francophile interested in 1m, 60cm,50cm , 40cm and smaller gauges . Build in scales from 1/6th to 1/24th. Also 1/32nd and 1/35th using 16.5mm track to represent 50cm and 60cm gauges. http://www.rue-d-etropal.com
