Resolving Open / Non-Manifold Meshes

All Model/s must be fully closed, manifold and watertight. There must be no holes or gaps within a model. Single surfaces& open or disjointed meshes cannot be printed. Slicing software may either register objects incorrectly or not register objects at all.

Single Surfaces

Single surfaces cannot be printed as they have a 0mm wall thickness. To print a surface, you will need to add a wall thickness or volume This can be done by;

Offsetting the surface or mesh to add a wall thickness

Single surface with no thickness (0mm)

Offset surface

Closing or capping the surface if the surface features a planar edge

Single Surface hemisphere

surface capped to create a solid object

If a surface does not already contain a planar edge, one can be created by splitting the object with a plane.

Mesh trimmed using a plane

Mesh capped to create a solid

Open/DIsjointed Meshes

Open / Disjointed Meshes can be resolved capping , patching holes in a surface or joining faces together to create a closed mesh.

Open mesh containing naked edges

surface built to resolve naked edges

Non-Manifold

A non-manifold geometry refers to a geometry that is not physically possible.

Geometries are considered non-manifold when an edge is shared by more than two faces or when two faces meet with opposing

Internal Surfaces

Object with internal surface/s results in edges connected to more than 2 faces.

Delete all internal surfaces

Objects joined at single edge

Objects aligned and joined at a single edge results in single edge that is connected to 4 faces

✓ Objects overlapped and joined together results in edges connected to 2 faces only. Click on the image to zoom in!
