It may be necessary to edit or re-export of the original 3D CAD file. This is sometimes an easy fix within the STL, but that is not always the case. Holes / / Missing triangles from a region prevents a closed mesh. Adding thickness or clearance where needed can sometimes help solve faulty edges. This requires STL repair and we recommend re-modeling the areas where the boundary edges were detected in the native CAD software. Many times, bad edges that are very close to one another may be stitched together to close the mesh. Simple STL editing software will enable you to flip the direction of the normal to correct the issues.īad Edges / / The edge of a triangle is not adjacent to another triangle edge. Because of this, slicing software will be unable to create contours for printing. Inverted Normal / / A triangle’s normal is flipped the wrong way which creates an open mesh.
