Quality Assurance
Products made using the FDM (Fused Deposition Modeling) method have a number of visual and tactile features that are normal for the technology and are not considered defects. These features are due to the very nature of FDM printing technology and do not affect the functionality of the product.

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.
