If you have not printed a model in porcelain you can't sell it in porcelain. However you should be able to sell it in other material options. If you have purchased in porcelain but still can't sell it you may be experiencing a bug. Another thing to check are the little eye shaped icons to the right of each material in the pricing list. If they are grayed out see if you can click on them to return them to a dark black color.
I have purchased it in porcelain. The eye shaped icons are not working. When i click it it works, but he dont save the settings. So can somebody please fix it!
I have similar problems. Purchased porcelain not sellable. See my earlier post on this, it's highly frustrating.
