Do you guys verify your own items before putting it up for sale? When I upload my models they pass the preliminary checks..then it goes to the printing process and the gets declined.. think most likely this has to do with the wall thickness for different materials. Like the plastics only require 1mm, but for ceramics its 3mm. So when I try to order in ceramics the printing gets declined. Does anyone find this to be a problem? I find that selling items that don't pass checks is very unprofessional in my opinion... The issue is that if an order is made for multiple items then one item passes then it's printed and the others are canceled... and there is no option to print as a batch..so all or nothing...Right now I have not placed any items for sale in the marketplace rather that I am checking to see if items can be printed..and there is no way for me to check every item i would put up for sale because of the hefty cost. Again if i just used white plastics then not an issue... Anyone have thoughts on this issue?
