Introduction
My company is looking to create a Web 3D Show Room, and we needed to figure out a fast way to acquire 3D model files. Our PM invited a vendor to give a presentation, and I jotted down some notes.
Optical Scanner (Handheld) - Artec 3D SPACE SPIDER | Suggested price around 1.2 million (Scanning a graphics card: 0.5 to 1+ hours)
Characteristics
- Can scan colors, but saturation is poor.
- Black and shiny surfaces affect the scan imaging, causing noise.
- Transparent and glossy surfaces can be sprayed with a powder to aid imaging.
Use Cases
- Medical aesthetics industry: for scanning faces, pre-op/post-op comparisons.
- For toys: can produce very complete scans, requiring almost no post-processing.
Scanning Process (Somewhat time-consuming)
- Scanning
- Rescanning unclear areas.
- Using software to align features and quickly merge multiple scanned models.
- Exporting the 3D model (Requires a high-end graphics card).
- Post-processing.

Merging Based on Features

Laser 3D Scanner (Handheld) - HandyScan Black | Suggested price around 1.28 million (Scanning a graphics card: ~10-20 minutes)
Characteristics
- Fast and precise, but cannot scan colors or human bodies.
- Accuracy can reach 0.01 mm.
- The turntable requires positioning targets; each target costs 3-4 TWD (consumable).
- By the way, I asked a designer about this. They said applying textures isn't the hard part; what's really labor-intensive is preparing the model's surfaces for texturing (i.e., UV unwrapping).
Use Cases
- National Palace Museum collection
- Video games, movies
- Factory product inspection (checking for deformation, tolerance)
- Automotive parts inspection
Scanning Process (Very fast)
- Pairing with (scanning) the positioning targets on the turntable.
- Scanning
- Exporting
- Post-processing

Training
On-site training to get us up and running. Awaiting a quote.
Conclusion
The vendor suggested that because we need to display products online and require high color saturation, a laser scanner combined with texturing would better suit our needs.
