Check STL files for watertight geometry. Detect holes and boundary edges that can cause 3D printing failures, simulation issues, and manufacturing problems.
Upload STL files to detect holes and boundary edges that create non-watertight geometry, causing issues in 3D printing and simulations.
Watertight meshes have no holes or gaps - every edge is shared by exactly two faces. Non-watertight geometry can cause:

Supports ASCII and Binary STL formats
Professional watertight mesh analysis tools for 3D printing and manufacturing quality control
Advanced algorithms detect boundary edges and gaps that create non-watertight geometry issues.
Hole edges are highlighted in yellow with affected triangles marked for precise problem identification.
Generate detailed reports with hole coordinates, repair recommendations, and quality improvement tips.
Ensure watertight geometry for reliable 3D printing, volume calculations, and simulation accuracy
Prevent support generation failures, inconsistent layer slicing, and print defects caused by mesh holes.
CFD and volume-based simulations require watertight meshes for proper boundary condition enforcement.
Validate mesh integrity before production to ensure accurate volume calculations and toolpath generation.
Watertight meshes are essential for manufacturing applications, 3D printing, and engineering simulations. Our hole checker identifies boundary edges that create gaps in mesh geometry, preventing downstream issues.
