Ashlar-Vellum CAD and 3D modeling programs are the best choice for designing products for 3D printing.

Why?

Because Cobalt™, Xenon™ and Argon™:

  • Create true solids, not merely a collection of surfaces loosely knitted together.
  • Use a real solid-geometric engine that knows how to handle:
    • common edges
    • tolerant edges
    • closed sets of analytic geometry
    • closed sets of NURB surfaces
  • Allow you to start not only with a solid model, but optionally with wireframe or surfaces and still be able to bring them together as a water-tight solid.
  • Allow control of meshing parameters individually for each solid in the file prior to STL export so that they can be set only once or adjusted more conveniently.
  • Allow you to optionally export each part in a file to a separate file for more control while printing.
