Strength Anisotropy
Part is stronger across layers than along them.
Mechanical property of FDM. Parts can delaminate under high stress along layer lines.

Layered Structure
Visible layer lines.
Result of layered manufacturing.

Support Marks
Small marks where supports were.
Expected residue.

Z-Seam
Start/end point of layers.
Usually placed in corners.

Surface Texture
Minor roughness on complex shapes.
Technological norm.

Overhangs
Drooping on unsupported areas.
Depends on geometry.

Tolerances
Minor size deviations.
Physical property of cooling.

Color
Slight shade variations.
Filament batch differences.

Stringing
Thin plastic hairs.
Easily removed.

Quality Assurance
These features are due to the very nature of FDM printing technology and do not affect the functionality of the product.
