3D printing and 3D printers are being used more and more in everyday life.
NEWS
To help solve cases faster and more effectively, the Hong Kong Police (China) have brought in 3D printers to rebuild crime scenes. This is not the first time 3D printing has been used in criminal investigations around the world. According to major newspapers, the Hong Kong Police have invested in two 3D printers to build crime scene models. Since 1988, the Hong Kong Police have built 18 large crime scene models at the request of the court for forensic review. The 3D printers will certainly speed up this process. The decision is the latest move to put 3D printing into real-world use, after it was proven in countries such as the US and Germany… Chuyentaomau.com – Useful information about 3D printers.APPLICATIONS

3D technology in investigation and forensics
Building crime scene models no longer relies only on photos and hand drawings. 3D technology lets investigators record a scene objectively, so they can review and measure it many times after the scene has changed. Some common uses around the world:
- 3D scene scanning: long-range laser scanners capture an entire room or street, with the position of objects and traces at true scale.
- 3D printed scene models: scale models help judges and juries picture the layout more easily than 2D photos.
- Evidence replicas: 3D printed copies of shoe prints, tools and fragments can be analyzed without damaging the original evidence.
- Forensic anthropology: skulls and bones are scanned and reprinted for study or facial reconstruction.
From scan data to a 3D printed model: the main steps
| Step | Description |
|---|---|
| Data capture | Laser scanning or photogrammetry from many angles to collect spatial data |
| Model processing | Merge the data, clean it up and simplify unnecessary details |
| Scale and splitting | Choose a suitable scale and split the model into parts for printing and assembly |
| 3D printing | Usually FDM for large bases and resin for small parts that need sharp detail |
| Finishing | Paint, mark positions and mount on a base for display |
Similar uses in civilian work
The same approach is used in architecture, heritage conservation, safety training and insurance assessment. A 3D printed scale model helps everyone involved communicate far better than drawings. Teams that need visual models from 3D data can check out 3D printing services for models and site models to choose the right material and scale.
Frequently asked questions
Why is a 3D printed crime scene model more useful than photos?
A 3D model shows the true scale and spatial relationships between objects, which 2D photos can easily distort because of camera angles. Viewers can look at it from all sides and understand the scene faster.
What technology is used to print crime scene models?
Bases and large structures are usually printed with FDM to save cost, while small parts that need sharp detail can be printed in resin. Some teams use multi-color 3D printing to show real colors.
How long does it take to 3D scan a crime scene?
It depends on the size and complexity of the space. A room can often be scanned quickly with a long-range scanner. Processing the data and building the model afterward usually takes longer.
Is this technology used in Vietnam?
3D scanning and 3D printing are widely used in Vietnam in architecture, mechanical engineering, healthcare and heritage conservation. In investigations, adoption depends on the regulations and investment of the authorities.
