Project brief

This project follows a mechanical support bracket from a dimensioned profile to a printable model and machine toolpaths. The CAD work uses SOLIDWORKS sketches, geometric constraints, extrusion, reference planes and material-removal features to create and revise the part. The report documents a grooved upper surface, lightweight openings and a later side-cut revision, connecting the drawing requirements to the finished geometry. The model then moves through STL export into PrusaSlicer for FDM preparation. Three scenarios vary layer height, infill, support and raft settings so that the preparation process can be compared in terms of estimated print time and material use. The lowest-material scenario uses a 0.20 mm layer height and 10% infill, while the finest scenario uses 0.10 mm layers and 60% infill. Toolpath preview and binary G-code export form the final preparation steps. The comparison presents slicer estimates rather than measured production performance, and the report does not establish dimensional accuracy or mechanical strength through physical testing. Its main contribution is a documented design-to-slicing workflow with visible CAD evidence and explicit manufacturing trade-offs.

The engineering challenge

Turn a dimensioned bracket into an editable solid model, then evaluate how print preparation choices change the required time and material.

Engineering approach

  1. Build a constrained profile and extrude the primary bracket geometry.
  2. Use a reference plane and cut features to revise the solid model.
  3. Export the model as STL and configure three FDM slicing scenarios.
  4. Inspect the layer preview and compare reported time and material estimates before G-code export.
