Changing product size for selling

I printed an item at 50% but would like to change the size to 100% to sell it at 100% size. Can I change the size or must I print it at 100% in order to sell it at 100%?

Hello,

Could you please clarify if you have already added an item at 50% to your shop? To advise you further I would like to ask you to send us a message via Contact Us form: https://i.materialise.com/en/contact
Please fill in the order reference so we can check the printability of the item at 100%.

Thank you.

Best regards,
Tetiana
