| Model rejected at print, but not on upload [message #48609] Thu, 17 May 2012 20:43 UTC |

I've been having some trouble getting something printed, and I've discussed it in the "Work in Progress" part of the forum.
But my question for here is why does my model pass the upload test but then get rejected when it comes time to print.
This gives me about 2 days in-between each time I try to fix the model and when I find out if the fix was enough.
It would be nice if there was a way to know upfront whether a model has truly passed. Maybe a plugin for ZBrush or Maya, or something like that would be nice.

For the automated system to catch all problematic models, across all the possible models which could be designed, the problematic issue has to be defined in a very strict way which the computer can use.
It is an algorithmically difficult task to do this generally, even though it may be immediately apparent to a human viewing the model that there is a specific problem. The shapeways staff have spent a great deal of time attempting to define exactly what will and will not survive printing, so that they can add them to their automated checks... but the task is in no way done.

The "final" checks are done by a human as they try to assemble the group of items to be printed together in a single batch .
The "initial" (computer) checks are not rigorous enough ensure that a model is fully printable.
You can send your file to service@shapeways.com and ask for a check before you order the model... that may save you some cycle time. You will also find that as you learn the limitations, it's often possible to get a model accepted without any rejects.
