Hi everyone, I just did a quick search on zcorp, and found some posts from last year where people seemed to have issues getting a good 3D print from an AC model. We're a service bureau, specializing in architectural models using the ZCorp printer mostly, and some SLA as well. We've also been using AC for a couple of years, with great success. If anyone has questions on the process, I'd be happy to help. You can see many examples of these models at alchemymodels.com.
