Reverse Engineering LEGO 4x2 Brick

Scan-to-CAD reverse engineering workflow using Polycam, Blender mesh repair, SolidWorks reconstruction, Bambu Studio, and 3D printing.

Reverse-engineering workflow for a LEGO 4x2 brick and print-ready puzzle geometry, with scan, mesh, CAD, and print files prepared for later visual export.

Overview

This project is separated from the plier project so the scan-to-CAD workflow can stand on its own.

The work covers scan capture, mesh repair, CAD reconstruction, and additive-manufacturing preparation.

02

Problem

The task was to move from scan data toward repaired mesh and CAD geometry suitable for additive manufacturing.

The current public page needs clean exported screenshots before the visual gallery can be filled.

03

My Role

  • Worked through photogrammetry/scan capture and mesh repair workflow
  • Used Blender and SolidWorks as part of the reconstruction process
  • Prepared the project as a manual-export target
04

Process

  1. Scan and mesh repair

    Polycam and Blender were used as part of the scan-to-mesh workflow before CAD reconstruction.

  2. CAD reconstruction

    SolidWorks was used to rebuild geometry in a cleaner engineering format.

  3. Print preparation

    Bambu Studio and 3D printing context connect the reconstructed model to a practical manufacturing path.

Key Decisions

Reverse-engineering workflow

The project connects scan capture, mesh cleanup, CAD reconstruction, and print preparation.

Current asset gap

Source files exist, but the public page still needs clean screenshots or renders before it is visually complete.

06

Project Material

Selected project images are not currently published for this project.

07

Outcome

A separate project page prepared for clean scan, mesh, CAD, and print-preparation visuals.

Relevant to reverse engineering and additive manufacturing because it connects scan data to repaired geometry, CAD reconstruction, and print preparation.

Next Steps

  • Scan-to-CAD projects need clear exports at each step so the workflow is easy to review.
  • A public page should separate cleaned screenshots from raw working files.
  • Export clean screenshots from the scan, mesh, CAD, and slicing workflow.
  • Add those visuals before treating the page as visually complete.
