Dimensional Changes from CAD model to Printed Part: Plastic expands and contracts as it is heated and cooled, and this thermal expansion/contraction causes dimensional variation in parts. Dimensional variation is also caused by the discrete nature of filament deposition, with the thickness of each layer corresponding to the diameter of the extrusion nozzle. To create dimensional accurate parts, adjustments must be made to CAD models. Outer features expand and inner features shrink as shown in the pictures below.
