In this article, we’ll be taking a more in-depth look at real 3D scanning. Read on to get the inside scoop.
Know the Different Types of Real 3D Scanner
There are several 3D scanners, including structured light scanners, laser scanners, and time-of-flight scanners.
Light Scanners
Light scanners use an infrared light emitter to project a pattern of stripes, grids, or dots onto the scanned object. This pattern is then picked up by a camera that can be placed close to the emitter or as far away as a few meters. By keeping track of how this light pattern changes as the object is rotated, these scanners can create a 3D model by figuring out how far apart each point of light is.
Light 3D scanners are easy to use, don’t cost much to make, and can accurately capture colors or even materials. Light scanners are very popular because they are a quick and easy way to get 3D data. This makes them useful in a wide range of situations.
Laser Scanners
Laser scanners are some of the most commonly used 3D scanners and are used for a variety of applications. These scanners use intense pulses of laser light to capture precise 3D shapes. 3D laser scanners can capture the surface of an object and create a ‘point map’ of the scene. The intensity of the laser beam and the shape of the reflectors determines the accuracy of the scan.
Laser scanners are used in engineering and manufacturing, legal forensics, 3D printing, energy and construction industry, and many more applications. Some laser scanners use a single beam, while others use multiple beams. The output of the scan is usually a series of points with x,y,z coordinates.
They are known for their high resolution and accuracy and are used to capture high level of detail of objects. Laser scanners can be used to capture large projects and perform measurements.
Time-of-Flight Scanners
They work by emitting light of a certain wavelength and measuring the time required for it to be reflected back to the scanner. In this way, its sensors measure the distance between the scanner and the object. The data generated are then used to create a 3D image of the object.
The scanners offer high resolution and accuracy, and can scan even complex and curved surfaces. They are commonly used in manufacturing, architecture and other engineering applications.
Additionally, they can also be used in medical and archeological imaging. They offer accurate fidelity and can distinguish between different textures and materials. With their high resolution, they are perfect for reverse engineering and digital preservation of objects.
Determine Resolution
The resolution of a 3D scanner determines the smallest size feature that can be accurately captured, so if you’re scanning something with intricate details, there’s no substitute for a higher resolution scanner. You should also consider the size of the object being scanned, as larger objects will require a 3D scanner with a higher resolution to accurately capture all the details.
Consider Range
Different scanners are available with a variety of range capability, often measured in millimeters or meters. Those requiring larger scanning distances should look into long-range structured light 3D scanners or laser scanners, which offer far greater ranges than other technologies.
For smaller objects, choices can range from contact-based scanners and structured light scanners, to time-of-flight and optical scanners. Different scan solutions also have different resolution, speed, and accuracy, so this should all be factored into consideration when selecting the right 3D scanner.
Define Accuracy
It’s important to consider accuracy when you’ll choose a 3d scanner, since higher accuracy scanners will provide more accurate data and thus, more reliable results. Accuracy is typically measured in micrometers, the smallest measurement of length, and is typically represented as a range.
For example, an accuracy range of 0.05 to 0.3 millimeters means the scanner readings will vary by up to 0.3 millimeters from the actual object. A 3D scanner with higher accuracy will provide you with more detailed results, which will save you time when creating a 3D model.
Choose Speed
Choosing a 3D scanner with a high speed scanner is an important factor to consider. A faster 3D scanner (just like this 3d model scanner!) can get the job done faster, meaning you can focus more time on other tasks.
Additionally, faster 3D scanners have better image quality, making it easier to digitize complex objects. Depending on your requirements, you can try to measure the speed of the 3D scanner, as speed greatly influences the amount of time required for projects.
Consider Portability
If you need to take the scanner on the go or scan objects in hard-to-reach locations, you’ll want a portable scanner. Portable scanners are typically smaller and lighter than non-portable scanners, and may be battery-powered.
Check Compatibility
Compatibility can be assessed in terms of 3D scanner type and 3D printer type. For instance, if you have an industrial 3D printer, it may require a professional 3D scanner to build the object accurately and efficiently.
Some 3D scanners are designed with features that are specific to certain 3D printer types, such as buttons for bed leveling or print head temperature setting. Additionally, if you plan to use a 3D scan data in CAD software, make sure it exports a CAD-compatible file format.
Choose What’s Right For You!
Overall, making sure to consider a 3D scanner’s accuracy, resolution, speed and price are key for choosing the right 3D scanner for you. Though the process can be daunting, finding guides like this one to help sort out the details can make the process much smoother.
