Blender 3D Printing by Example

Thinking about size

Once you have an idea of which printing process will be used, I recommend thinking about the final size of your piece. We've put some thought into how high we want to emboss detailing as well as our wall thicknesses. If we made our entire model without thinking of the final dimensions, we would have to resize everything accordingly at the end.

If I scaled my piece down, suddenly I may have walls that are too thin to pass the automated checks at one of the 3D Printing Service Bureaus. Or perhaps I scaled my final piece up, making all my vertical detailing too large for an FFF/FDM printer to make without adding extra supports. You always have the ability to edit your model and there is indeed a natural iterative process ...
