Design Guide for 3D Printing

The following information is provided to help you print successfully.

  • Solids and Manifold Geometry (often referred to as air-tight or water-tight)
    • unintentional “holes”
    • “naked edges”
    • non-manifold edges
  • Thin Walls/Joints/Wires
    • planes (surfaces without a thickness)
    • thin walls (minimum wall thickness: 0.7mm or 0.028in)
    • thin joints (might want to consider higher than minimum wall thickness)
    • thin “wires,” should be minimum 1mm (thicker if half inch or more)
  • Moving Parts
    • allow 0.5mm tolerance between parts for the addition and dissolving of support material
  • Inverted Normals (faces)
    • flipped faces/inward facing surfaces
  • Multiple or Intersecting Meshes and Shells
    • unresolved geometry on the interior of models
    • multiple, colliding solids where only one should exist
    • individual models should be separate files
  • Scale (mm/inches)
    • printer bed is 10″x10″ and can print up to 12″ in Z axis
  • Remove Shell Noise
    • duplicate messes
    • hidden surfaces
    • random disconnected objects (will probably become more common with scanned objects)
  • Polygon Count
