What do you do if you can't decide between 3D scanning tools for product design?

1 Types of 3D scanning tools

There are three main types of 3D scanning tools: photogrammetry, structured light, and laser. Photogrammetry uses multiple photos of an object from different angles to create a 3D model. Structured light projects a pattern of light onto an object and measures how it is distorted by the surface. Laser scans an object with a beam of light and measures the distance and angle of the reflection. Each type has its own advantages and limitations, depending on the size, shape, and material of the object you want to scan.

2 Photogrammetry pros and cons

Photogrammetry is the cheapest and most accessible type of 3D scanning, as you can use any camera or smartphone to take photos of your object. It is also good for scanning large or complex objects, such as buildings or landscapes, that are difficult to scan with other methods. However, photogrammetry requires a lot of photos, which can take time and storage space. It also depends on the lighting and quality of the photos, which can affect the accuracy and detail of the 3D model. Photogrammetry is not suitable for scanning shiny, transparent, or dark objects, as they can cause reflections or shadows that confuse the software.

3 Structured light pros and cons

Structured light is a fast and accurate type of 3D scanning, as it can capture the shape and texture of an object in one scan. It is also good for scanning small or medium-sized objects, such as jewelry or toys, that have fine details and colors. However, structured light is more expensive and less portable than photogrammetry, as it requires a special device and a stable setup. It also has a limited range and field of view, which means you may need to scan your object from multiple angles and stitch the scans together. Structured light is not suitable for scanning moving or shiny objects, as they can interfere with the light pattern.

4 Laser pros and cons

Laser is a precise and reliable type of 3D scanning, as it can measure the distance and angle of each point on an object's surface. It is also good for scanning objects that have a uniform color or texture, such as metal or wood, that are hard to scan with other methods. However, laser is the most expensive and complex type of 3D scanning, as it requires a high-end device and a skilled operator. It also has a slow scanning speed and a low resolution, which means it may not capture the subtle variations and details of an object. Laser is not suitable for scanning objects that are sensitive to heat or light, as they can be damaged by the laser beam.

5 Tips to choose the best 3D scanning tool

When selecting the best 3D scanning tool for your product design project, you need to consider various factors such as the size, shape, and material of the object you want to scan; the level of accuracy, detail, and texture you need for your 3D model; the budget, time, and resources you have for your project; as well as the compatibility and usability of the 3D scanning software and hardware. By evaluating these factors, you can compare the pros and cons of each type of 3D scanning tool and choose the one that meets your requirements and expectations. Additionally, you may want to try different 3D scanning tools to see how they perform on your object or use a combination of tools to achieve optimal results.
