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!

NetFabb Basic has all the tools that you would need for re-scaling, checking wall thickness and the volume of the model is shown. Grab a calculator & use prices from the Materials page to get the actual cost, add 19% Dutch VAT if you're in a EU country, but NetFabb Basic is free to all.
And you might be able to get around the upload filesize limit by zipping or even double zipping the file - I've seen files packed to 1/5th the size using double zipping.
