Reduce Printing Costs
To help optimize the price of material used, the Wolfram Language provides utility functions such as ShellRegion to hollow out models.
In[1]:=

original =
ExampleData[{"Geometry3D", "Triceratops"}, "BoundaryMeshRegion"]
Out[1]=

Hollow out the model.
In[2]:=

hollow = ShellRegion[original];
Show[hollow, BaseStyle -> Opacity[0.4]]
Out[2]=

Saving more than half of the material and reducing printing costs.
In[3]:=

Volume[hollow]/Volume[original]
Out[3]=

Print the model.
In[4]:=

Printout3D[hollow, "3DHubs", RegionSize -> 3]
Out[4]=
