Overview
3D scanning is the process of capturing the shape and dimensions of a physical object and converting it into a digital 3D model. The scanner uses technologies such as laser scanning, structured light, or photogrammetry to collect precise spatial data. These digital models support detailed analysis, replication, and design modification.
3D scanning in the MakerLab is self-service. Patrons submit a ticket to request a time and date to visit the MakerLab. MakerLab staff will work with the patron to verify availability and confirm or change the reservation time. Patrons can use their own computer if it fits the below requirements or borrow one from the lab.
At the agreed reservation time, patrons will bring the object to be scanned to the MakerLab. Staff will be available for assistance if needed.

Design Considerations
Object Surface
- 3D scanners (especially structured light or laser scanners) rely on detecting surface detail, so surface properties matter a lot.
- Best:
- Matte, non-reflective surfaces
- Light to medium tones (gray, white, beige)
- Avoid:
- Glossy, shiny, or transparent surfaces → they reflect light and confuse the scanner
- Very dark black or highly reflective metal → causes scanning errors
Geometry & Features
- Best shapes: Volumetric, complex geometry with plenty of edges or features.
- Harder to scan: Smooth, flat surfaces or symmetrical objects (harder to align).
Resolution & Accuracy Needs
- Higher resolution = more detail but longer scan + heavier file
- Choose resolution based on:
- End use (e.g. 3D printing, analysis, visualization)
- Hardware/software limits
Scanning Environment
- Use consistent, diffuse lighting
- Avoid direct sunlight or harsh shadows
- Stabilize both the object and scanner (especially in handheld mode)
