Before you start

Generated geometry is not automatically watertight or printable. This workflow separates visual repair, solid validation, fabrication checks, and slicer verification.

Prerequisites

  • A generated mesh
  • A mesh-repair tool
  • A slicer for the target printer
  • Known material and minimum-feature constraints

Step by step

Set real-world dimensions

Choose units and final size first; wall thickness and small features only make sense at a physical scale.

Inspect the surface

Find boundaries, self-intersections, non-manifold edges, internal shells, reversed normals, and disconnected fragments.

Create and verify a closed volume

Repair or reconstruct deliberately, then compare the silhouette and thin features with the original before discarding it.

Check fabrication limits

Measure wall thickness, clearances, unsupported overhangs, contact area, and fragile parts for the chosen process and material.

Validate in the slicer

Review layer preview, supports, islands, estimated material, and warnings on the exact printer profile.

Every intended region appears continuously in the layer preview.

Known trade-offs

  • Watertight does not mean printable
  • Automatic hole filling can bridge openings that are intentional parts of the object
  • Textures and PBR maps usually do not transfer to single-material mesh printing
