Week 5: 3D Scanning and printing
Evaluation of Design Rules for 3D Printing
Materials and Methods
- Printer used: Bambu Lab X1 Carbon
- Material: PETG
- Modeling software: SolidWorks
- Slicing software: Cura / PrusaSlicer / Bambu Studio
- Key parameters:
- Layer resolution: 0.2 mm
- Infill: 20%
- Extruder temperature: 220°C
- Bed temperature: 55°C
Test Designs
Test structures were designed and printed to evaluate:
- Supports: Pieces with different overhang angles (15°, 20°, 30°, 45°).
- Bridges: Distances of 5 mm, 10 mm, and 15 mm.
- Dimensions and tolerances.
- Anisotropy.
Design and Printing of a Non-Subtractive Object
A model was created in SolidWorks that cannot be fabricated using subtractive methods.
3D Scanning of an Object
Scanning Methods
A mobile phone and a 3D scanner were used to capture the geometry of a physical object.
Mobile Phone Scanning
- Application used: KIRI Engine
- Procedure:
- A video and multiple photos were taken from different angles.
- Images were processed with 3D reconstruction software.
- An STL file of the object was generated.
Week 5: Conclusion
Successfully designed, printed, and scanned 3D objects, evaluating the limitations and capabilities of each method.
