Industrial CT scanning inspection services have been used for a while with good, accurate results. however, the information regarding different types of industrial CT scanning inspection services is not always correct. For example, there are so many misconceptions regarding 3D scanning services. 3D scanning is used as part of industrial CT scanning. Let’s debunk a few of the common myths that you may have heard regarding 3D scanning and industrial CT scanning inspection services. You may be surprised at what you learn.
Myth:3D scanning is the most expensive type of scanning.
Truth:3D scanning has actually dropped in price in recent years. While it still does cost money, the overall expense of using the machine and engaging in 3D scanning has gone down considerably. Industrial CT scanning inspection services are used to make 3D scanning more accurate and quicker while still offering the same amount of quality.
Myth:All scanners produce the same quality.
Truth:Words can not express how false the above statement is. There are different levels of 3D scanners that offer different results. Quality can be lower or higher depending on the type of machine that is used. Advances are constantly being made in the technology of the scanners so if you are using an older machine you are going to get lower quality results whereas new machines with new technology and better design will provide better results.
Myth:3D scanning is not an accurate method for all applications.
Truth:It’s a common misconception that 3D scanning doesn’t work well for complex applications in particular. Again, this is not true. Maybe it was previously but vast improvements have been made and the technology of 3D scanners are now even better than other methods that traditionally were thought to be more accurate.
Myth:3D canning is only capable of capturing external geometry.
Truth:There are high accuracy machines available that can scan the internal geometry of parts. Internal geometry of parts is extremely complex so it’s understandable that someone would think that a 3D scanner can not capture it but the speed and precision used nowadays in 3D scanning makes it very possible.
Myth:3D scanning is limited when it comes to extra large or extra small objects.
Truth:There is no part that is too big or too small to be scanned by 3D imaging. There are no limitations on either side of the spectrum. Parts are scanned that are smaller than a pen mark and larger than a football field. Sure, adjustments have to be made, but it can be done.
Myth:3D scanning takes a very long time.
Truth:Recent upgrades have cut down on scanning time immensely. A small part will only take around 15 minutes in total to scan. The bigger the part, the more time it takes but typically, 3D scanning is done anywhere from 30,000 points per second to 225,000 points per second. Lasers work a lot faster than mechanical tracing systems do.
Myth:You cannot edit images scanned by a 3D scanner.
Truth:Editing images is not based on the type of scanner that is used but the software that it is linked to. As long as there is editable software receiving the data from the scanner, there is no reason that the image would not be able to be edited if and when necessary.
Myth:3D scanning has too much noise.
Truth:It is true that raw data may have a lot of what is called, noise in the engineering world but there are now filters that have been manufactured to cut through the noise in order to get rid of erroneous data before it is analysed. The data that is left after this process can all be used as it is left in perfect condition.
Myth:The data that is gathered from 3D scanning is inferior to touch probes.
Truth: Not so. While both techniques do still make use of a high accuracy machine, a 3D scanner can capture tens of thousands of points per second and can almost immediately define the shape and size of the object into the software. This alone makes the 3D scanner superior to touch probes which only scan hundreds of points per second.
Hopefully this will give you a better idea of 3D scanning and how much it has evolved technologically in the past few years.
