What is a 3D Scanner?
[su_accordion][su_note note_color=”#66e0ff”]
A 3D scanner is used for analyzing data from real-world objects, specifically on its shape and appearance to construct digital 3D models. A 3D scanner comes from a wide range of variety based on different technologies, costs, and sizes. For example, some Handheld 3D scanners can analyze the human body for 3D data in detailed texture and in full color. In short, it is a great innovation for the 3D printing industry.
The technique of using a 3D scanner to capture the shape of an object is called 3D scanning because we get a 3-dimensional file. The 3D file can be saved, edited, and even can be printed using 3D printers. The 3D scannings are compatible with CAD (computer-aided design).

Kinds of 3D Scanners-
There are different kinds of 3D scanners based on their capabilities. Some 3D scanners are best suited for short-range scanning while others are mid or long-range scanning. There are industrial 3D scanners for prototyping, surgical, and dental clinics.
Short-range 3D Scanners:
These types of scanners are basically Laser triangulation or Structured Light scan technology. It is best suited for an object at a distance of 1 meter for scanning. These scanners are also of two categories-content and non-contact. In the first method, the object is laid out and fixed on a specific space to analyze it by physical touch. The non-contact method or SLS 3D scan projects light or radiation to assess an object’s surface. Triangulation and white light methods are more popular use among technologies.
Laser-Based 3D Scanners:
Laser-Based 3D scanners use a procedure called trigonometric triangulation to precisely capture a 3D shape as millions of points. After projecting a laser line or multiple lines on an object it captures the reflection of it with a single or multiple sensors. These scanners are able to scan even tough surfaces, shiny or dark finishes. It is portable and simpler in design. They are less sensitive to changing light conditions.
Projected or Structured Light 3D Scanners:
Historically known as “white light” 3D scanners are actually the most structured light 3D scanners. Nowadays they use blue or white LED light patterns which include bars, blocks, or other shapes onto an object. These types of scanners use similar triangulation methods as laser scanners. It can be tripod mounted or handheld as well. These scanners are generally used for their fast and accurate performance. It can scan in high resolution even as large as 48 inches. Multiple lenses can be used in this system. More importantly, it is safe for the eyes both for animals and humans. The various price range starts from low to high. The price depends on the resolution and accuracy.
Medium and Long Range 3D Scanners:
These kinds of 3D scanners come in two major variants- Pulse based and Phase shift. Both the scanners are well suited for large objects such as buildings, structures, aircraft, or military vehicles. These long-range 3D scanners are based on non-contact technique and therefore safe for all types of objects. They are portable and it can analyze millions of points in a single scan (up to 1 million points per second). This also includes good accuracy and good resolution based on object size.
Coordinate Measuring Machine (CMM):
A Coordinate measuring machine is used to inspect parts. This can be controlled manually and also with the help of computer software. It is one of the most accurate ways of measuring an object. The measurements are defined by attaching a probe to the machine. There are multiple software and certifications of measurements as per industry standards. For manufacturing, these machines are used as industrial 3D scanners.
Desktop 3D Scanners:
3D desktop scanners are next-generation scanners with multiple software. These scanners are mainly products of handheld 3D scanners with multiple scanning modes and maximum quality. This gives the device a high speed of scanning with multiple alignment systems.

BUYER’S GUIDE FOR 3D SCANNERS:
Technical Specs-
Accuracy
It is the most important aspect that a buyer should look for before buying a scanner. The manufacturer should ensure the accuracy best possible for the device. 3D scanners need to be calibrated and the manual adjustment feature gives the device optimal standard categorization.
Speed
It is measured by how fast the machine can scan be it long distance or short/ medium range product. The speed of the SLS 3D scanner is captured by the number of frames and the number of points captured per second. Some advanced white light 3D scanners only need one second to make 16 frames and capture 2 million points of the object.
Resolution
When choosing a 3D scanner it is important to measure the resolution that your device is capable to handle. The resolution is generally measured by millimeters, or microns. You need a high-resolution 3D scanner for a detailed analysis of a product. These features play important roles in the jewelry industry, quality control, reverse engineering, and many others.
Part Size
Before buying you need to think about the object sizes. Whether you will be capturing various sizes, small or large parts for scanning. For large parts (planes, cars, vehicles) you need long-range stationary laser scanners and short-range scanners for small objects.
Portability
Portable 3D scanners are an advantage nowadays to use anywhere anytime. There are scanners with internal/ external batteries that give more life to a scanner machine. You need to select what will be the surface and what you will be projecting. Heavy scanners are mainly industrial purposes but lightweight scanners are easier solutions to carry or move.
