Choosing 3D Scanners: What You Should Know

3d Printing and scanning

Thinking of buying a 3D scanner? There are plenty of advantages that will justify the purchase, regardless of whether you’re a hobbyist, a manufacturer, or a design professional. It cannot be denied, however, that the initial price that you have to consider is not the least expensive thing in the world. So it is important that you make sure that you choose the right scanner for your needs, so that you can truly put it to its full operational use. To help you, consider these factors.


Your Supplier

Where you intend to purchase your 3D scanner is crucial: the wrong choice can lead to a significant waste of your money. As such, make sure that your supplier has a long history that has seen many previous customers happy, as well as offers trusted products from established manufacturers. It is also important that you choose a supplier that can guide you through the selection process, such as Objective 3D Direct Manufacturing. This will make sure that you end up with the scanner that you need.


Your Objects

What you wish to scan is also important in the selection process. Some scanners work best for particular materials. Similarly, the size of the objects that you will scan matters. There are scanners that are more suited to scanning large areas, while others are limited to smaller objects.


Your Required Resolution and Accuracy

Scanners also differ according to their resolution and accuracy. Now, one important thing to note is that a low resolution may not necessarily mean low accuracy. A five-megapixel scanner, for instance, will only need a certain amount of scanned data to accurately render a five-millimetre flat object, after all. Similarly, high resolution does not automatically mean getting accurate scans. The object and design of your object still dictate the quality of results that you will get.


Your Scanning Environment

Finally, choose the best possible 3d scanner for your specific work environment. Most scanners will work well in normal scanning environments, especially with an appropriate lighting setup. However, if you intend to scan outdoors or on surfaces that may get exposed to shakes and vibrations, a specialised scanner may be necessary.

Regardless of your working environment, though, remember that it is important that you calibrate your 3d scanner properly. If you intend to use your scanner for 3d printing, calibration is even more important. And if you are adopting software programmes into your suite, get it working well with your scanner.
