Has anyone else had problems with the sintershell?

I have now had two orders with two different items were I have some very small parts, and the holes in the sintershell were too big and the fell through.

The first time this happened, my service was horrible. Normally shapeways service is pretty good but Either I got some one who didn't care to fix the problem or who just didn't understand the issue.

I wanted a reprint and a way to fix this from happening again, but understood it was not the run of the mill problem. It took about a week and the end result was I was told to fix things on my end and they refunded me the amount for the item to try again.....

are you kidding me? I can't fix your software, and I didn't want a refund, I needed the print and a way to fix the solution. They didn't even ask me if a refund instead was okay. My items are dolls so having the entire doll and it's 20-40 parts in one file is really helpful to me and to my customers so they don't have to try and find a ten thousand parts to buy individually, and not having a mesh is just not affordable. I tried making my own mesh, but even with trying really hard to get it compact, it obviously costs more then using shapeways mesh by quite a bit.

Now another item has had this problem pop up again, and I can only hope the person who helps me this time will actually try and help me resolve this.
I would just download the model and fix the mesh myself, but when I download it, it is some strange format that I can't work with...

So yeah... help please and please put your own problems you have had with the mesh so maybe we can get shapeways to step up and act upon it...

Most likely the strange format is x3db (the compact binary form of x3d), the free version of netfabb studio basic should be able to convert this to stl or other formats your software recognizes.

The precious metal material option provides a very cost effective strategy for one off production of Model engineering items.

However it would be good to know who is responsible for applying the shrinkage allowance normally anticipated in the investment casting process.
The allowance can vary as a function of material and volumetric geometry

I do not have a problem adding an allowance to the model before the STL is created, but would like guidance from Shapeways on what allowance would be anticipated before the model is uploaded for final costing and production.

Can the Shapeways team advise please
