Thanks for reaching out about this.
Printing an order that will end up costing you more in material costs then the amount you would earn is not exactly ideal so I would advise every hub to do the following.
During the review step of the order, before accepting, download the models that were send in and load them in your own slicing software. Check if the material volume that was automatically calculated by our slicing process is 100% accurate. If this is not the case, you can easily adjust the material volume here:
Then, if the model requires supports for printing, you can add these extra costs to the order by selecting the “Add additional services” on the right hand side of the order page.
I understand that it would be ideal to have all of this automatized but due to the fact that we still have a relatively small team and dozens of different 3D printers/printing techniques on the platform we are a bit outnumbered on this front.
We’ll be working on this in the future but for now, I hope this system works for you.
All the best,
Robin - Head of Customer Support - 3D Hubs
