Module 3: Mesh Processing and Export

Duration: 3 hours | Microcredential: MCCPDL-U11M3-v1.0

Module Overview

Module 3 covers the post-scanning workflow: converting raw point clouds into usable 3D meshes, cleaning and repairing mesh geometry, and exporting to appropriate file formats for 3D printing, CAD integration, and reverse engineering applications. Learners will use open-source mesh processing tools to develop a complete scan-to-output pipeline.

Learning Objectives

1. Convert a raw point cloud into a triangulated mesh using Poisson or Ball Pivoting reconstruction algorithms
2. Perform mesh cleanup operations including decimation, smoothing, hole filling, and noise removal
3. Evaluate mesh quality using triangle count, manifold checks, and dimensional verification
4. Export meshes in appropriate formats (STL, OBJ, PLY) for 3D printing, CAD, and visualization workflows
5. Describe the reverse engineering workflow from scan data to parametric CAD model
