Types of 3D Scanning Technologies
There are several types of 3D scanning technologies, including structured light scanning, laser triangulation, photogrammetry, and time-of-flight.
Structured Light Scanning
In the Structured Light Scanning method, a 3D scanner uses light patterns. It sends these patterns onto an object. Then, it looks how they change when they hit the object’s surface.
This helps to work out the shape of that object. This scanning method is good at picking up small details and smooth surfaces which makes it useful for 3D printing. A downside is that shiny or clear items can cause problems by bouncing off too much light.
Laser triangulation is one of the types of 3D scanning technologies used for 3D printing. It works by projecting a laser beam onto an object and measuring how the reflected light changes.
This helps to create a detailed 3D model of the object’s shape and surface. Laser triangulation scanners are known for their high accuracy, making them suitable for capturing fine details.
They can be used for various applications in 3D printing, such as quality control and reverse engineering. These scanners come in different sizes and price ranges, so you can choose one that fits your needs and budget.
Photogrammetry is a 3D scanning technique that uses photographs to create accurate 3D models. It works by analyzing the overlapping photos of an object or environment from different angles, and then using complex algorithms to reconstruct its shape and dimensions.
Photogrammetry offers a cost-effective option for 3D scanning, as it can be done with just a regular camera or even a smartphone. This makes it accessible for beginners in the world of 3D printing.
However, it’s worth noting that photogrammetry may not provide the same level of accuracy as other scanning methods like laser triangulation or structured light scanning. Nonetheless, it can still be suitable for certain applications such as capturing larger objects or creating rough prototypes.
Time-of-Flight is a type of 3D scanning technology that measures the distance between the scanner and an object by measuring the time it takes for light to travel from the scanner to the object and back.
This technology uses a sensor that emits laser pulses or infrared light, which bounce off the object and return to the sensor. By calculating how long this process takes, Time-of-Flight scanners can create highly accurate 3D models of objects.
They are known for their speed and ability to capture large areas in one scan. However, they may not be as detailed as other types of scanners.
