Hi all, this is Roni. Ralph from the Customer Service of Shapeways adviced me to post here. This is the project: Given is the SLT-data of a bust (original height: ca. 36cm, hollow inside). I already have that data taken from the original by professionals. (actually there are 2 SLT-files of 138MB together.) I want to make a cheap replica of that bust in reduced size: ca. 18cm. From the material-sheet on this website, I understand that 'White Strong Flexible' should be the material of choice here. (Ralph confirmed this.) Now my questions are: 1.) Do I need to change the SLT-data of the original model to fit the new size or can it be used for the reduced-size-version too? 2.) Since the size of my SLT-files is bigger than allowed for direct upload: how can I pre-calculate the approximate price of the item? Is there a way to make reasonable assuptions on the final cm^3 just from the knowledge about dimensions of the original? 3.) Do you think, it will be cheaper to make just one 3D-print of the new-sized model and then build a regular mold from it for further reproduction or is it better to make every single reproduction by 3D-print? Any ideas or advice is welcome! Thanks a lot in advance!
