# Are there any 3rd party gridMathematica services?

Posted 11 years ago
 I have some calculations that take many days to complete, up to a month or longer, on my one computer.  I don't have access to multiple computers.  Are there any organizations with great computing ability that i can hire to execute notebooks?

 What I am trying to accomplish is the creation of a high resolution object to export as a .stl file, so that I can 3d print it.  The object involves a 3d parametric curve of a square cross-section, excluded from a 3d parametrized surface.  Think of a sphere with a square groove worming around its surface, as an example.  I tried Solidworks but it doesn't handle intricate equation driven curves very well.  Buggy, and features are limitted in scope.  Mathematica is ideally positioned to generate 3D objects driven by complicated parametric equations, but unfortunately, RegionPlot3D is one of the only functions that can serve the purpose of designing 3d parts for export.  My surface can be defined in terms of xyz, but my curve cannot.  RegionPlot3D cannot interpret parametric equations, so I had to sample many xyz points from my parametric curve, and then define an irregular polyhedron (using surface normal planes, offset parallel planes, etc) around each point to approximate a small portion of the groove.  That's the best work-around I could come up with, anyway.  It looks like I will have to widen the groove a bit so that RegionPlot3D will recognize it with fewer PlotPoints. I am eagerly awaiting mathematica 10 (release date????) to see if it has any new features that might help, such as a RegionPlot3D function that can interpret both xyz and parametric equations.EDIT:   After some research, I've discovered that what I need is Programmatic CAD.  There are many free platforms available with a simple google search.  I will try one of these, but I would love to see Wolfram incorporate programatic CAD in the future.
