Lost Wax Casting Shrinkage Allowance & Export as STL for 3D Printing

I'm back with another Practical Rhino CAD Tutorial!
In this video tutorial, we take a look how to check your file for errors (naked edges) before 3D printing, how to scale your models to add an allowance to compensate for shrinkage during the lost wax casting process and also how to export your model as an STL mesh file, ready for 3D printing. Also includes an (very simplified) overview of the lost wax casting process.
As ever, as well as the HOW I’ll also be explaining the WHY, breaking down my decision making process along the way.
Presented and narrated by Jack Row FIPG.
Any questions, post them in the comments section.

Thank you for the clear instructions. It helps to take the guess work out of CAD to product.
