Thicken Plots for Printing

Use a theme to create filled plots for 3D printing.

In[1]:=

opts = {ImageSize -> 400, PlotRange -> All, PlotPoints -> 50};

In[2]:=

Plot3D[Cos[x^2 + y^2]/(x^2 + y^2 + 1), {x, -4, 4}, {y, -4, 4}, Evaluate[opts], RegionFunction -> Function[{x, y, z}, Sqrt[x^2 + y^2] <= 4 && (x <= 0 || y >= 0)], PlotTheme -> "FilledSurface"]

Out[2]=

Thicken the plots instead.

In[3]:=

Plot3D[Cos[x^2 + y^2]/(x^2 + y^2 + 1), {x, -4, 4}, {y, -4, 4}, Evaluate[opts], RegionFunction -> Function[{x, y, z}, Sqrt[x^2 + y^2] <= 4 && (x <= 0 || y >= 0)], PlotTheme -> "ThickSurface"]
