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!

Welcome Roni,

How thick is the 36cm model? If it's thick enough you could simply scale it down. If it's not then you'll have some work to do. For resizing look at MeshLab. You'll be able to resize, and reduce the file sizes in there for printing.

And for your future production question, that depends on quantity, and quality desired. The easiest thing is to let shapeways handle all the work Razz.

Hi Roni,

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.

Cheers,
Paul
