surface thickness for 3D printing

A friend is trying to use GeoGebra for 3D printing. She asks:

"For example, I was trying to print a simple object to test, so in Geogebra 3D I graphed the equation 25 = x^2 + y^2 to see a cylinder. The problem is that when I download it as an .stl, the surface is so super thin, and not actually 3D printable. I tried searching Geogebra help for making the walls of a 3D figure thicker, but none of them seemed to apply to the Geogebra3D cases. I'll keep hunting, but in the meantime I thought maybe one of you might know how to make a surface thicker with a command of some sort."

Is there a command to increase surface thickness?

Please try the new version (v508)

Hello, I am also trying to 3D print multiple variable functions on GeoGebra and what I got to the same problem that you are saying. Also I found a way around this "problem" If you are using the trace you can use the surface command: Surface( <Curve>, <Angle>, <Line> ) to rotate the function and get a printable surface. Or you can find the parametric equations for you functions (which can be quite simple) and then the surface is printable.


There is also an issue because now the default thickness is very thick but you can use the command; SetLineThickness to make it better but it seems not to be working in the STL file, Anyway it is a solution.

Hope this works for you.

We'll add a simple dialog to set the thickness in the future.
