Blender STL file is extremely small

Recommended Posts

I have a friend whose working on a design he wants me to 3D print

However the exported file he has sent me shows up very, very small in Cura

He's using Blender, something I don't know a thing about.

Any ideas on how I can guide him to a successful export I can use?

I don't know anything about Blender either, but is there no way to set physical dimensions?

Or, if it would be a sort of "freehand sculpture", without any reference to dimensions, maybe he could create a little cube next to it, and give that cube exact physical dimensions?

Since people can design planes exactly to scale in Blender, something like this should be possible.

Set the "Scale" in the STL export window to 1000 for mm or 100 for cm. Blender by default doesn't use units, but one unit is usually interpreted as 1 m, but imported in most other software as cm or mm (if using units options of "None" or "Metric").

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
