Week 5: 3D Scanning and Printing
Exploring additive manufacturing, digital design, and reverse engineering workflows.
1. Introduction
3D scanning and 3D printing are digital fabrication technologies used to create, replicate, and modify objects using digital models. 3D printing builds objects layer by layer, while 3D scanning captures real-world objects and converts them into digital models for editing or reproduction.
Group Assignment
Tested 3D printer design rules including overhangs, bridging, accuracy, and material behavior.
Individual Assignment
Designed and printed a complex object and performed 3D scanning of a real-world object.
3. Tools Used
- SOLIDWORKS (3D CAD Design Software)
- 3D Printer (FDM Technology)
- PLA Filament
- Slicing Software (G-code generation)
- 3D Scanning Tool / Application
- Computer for design and processing
4. Step-by-Step Process
1. Design in SOLIDWORKS
I created sketches using 2D tools and converted them into 3D models using Extrude, Fillet, and Cut features.
2. Exporting STL File
The final design was exported as an STL file for 3D printing.
3. Slicing Process
The STL file was imported into slicing software to generate G-code and adjust print settings.
4. 3D Printing
The model was printed layer by layer using PLA filament.
5. 3D Scanning
A real object was scanned and converted into a digital 3D model for analysis and reproduction.
5. Learning Outcomes
- Understanding advantages and limitations of 3D printing.
- Applying CAD design workflow using SOLIDWORKS.
- Learning full workflow from design to printed object.
- Understanding how 3D scanning digitizes real objects.
6. Conclusion
This assignment helped me understand the complete digital fabrication workflow from design to production. I gained skills in 3D modeling, slicing, printing, and scanning, and learned how digital tools connect to physical manufacturing.
