When you upload your 3D model and it contains errors (related to fixing), our software will try to fix them automatically. In case the errors can't be fixed automatically, you will see an offline price request (free of charge).
Sometimes, the price for an uploaded model cannot be automatically calculated. There are a few reasons why an error can occur:
When an error occurs, you will be able to request a price, free of charge. Our customer service team will then take a look at your model and your request. They will do a quick check to see if your model is suitable for 3D printing within your specified request. If not, they will advise you which design changes are necessary. This way, we want to make sure you get the best possible printed result.
In the case of serious design issues, we will ask you to redesign/modify the 3D model and upload again. To make sure you'll get a perfect result, we recommend you to read how to make a 3D printable file.
