My model "Doxie: Cute Pup" at https://www.shapeways.com/model/675137/doxie-cute-pup.html?m odelId=675137&materialId=62 Apparently can be printed in any material other than Ceramic (due to thickness issues) There seems to be no way to remove ceramic from the list of available materials for this model Why? How would I remove the ceramics category for this model?
Ceramic may be an option for YOU from your signon, but it is not an option for the buying public. Try logging out and see if you still see Ceramic.. I do not.
