Wall Thickness

  • The ideal wall thickness is between 1.5 mm and 3.0 mm (0.06 inches and 0.12 inches)
  • Most important is to have a consistent wall thickness, try to keep all walls the same thickness avoiding extreme wall thickness variations – large blocks of material will cause excess heat and shrinkage resulting in part deformation
  • Make any internal and/or external ribs, gussets or baffles no thicker than 60% of their adjoining wall thickness
