3D scanners are often used by dentists and orthodontists to make prosthetic teeth or braces
customized for individual patients. The traditional method uses plaster casts to create teeth
molds, but 3D scanners can achieve far greater results for dental treatments with improved
efficiency. 3D images provide detailed information on the shapes of teeth without patients
having to bite down on a mold or a piece of plastic.
A plastic surgeon can also utilize 3D scanning and printing to show patients how they will
look after the surgery. This gives patients a greater understanding of what to expect from the
surgery, thus facilitating communications between surgeon and patient.
3D scanning also enhances the overall patient treatment experience for prosthetics. Without
putting any pressure on the affected part of the body, a 3D scanner can quickly capture 3D
images to design customized prosthetic devices.
Overall, 3D scanning enables less invasive treatments, minimizing potential medical issues
or complaints that come with using traditional plaster casts. For this reason, 3D scanners
are expected to be widely used in various medical fields.
Reverse engineering also referred to as backward engineering, is the process of extracting
digital data from pre-existing objects and reproducing them based on the data gathered.
Generally, there are three major steps involved in reverse engineering a physical object:
data gathering, data processing, and further working the models. The most critical step
here is data gathering which involves converting a physical object into digital data.
Today, many manufacturers struggle to digitize their parts, often using the traditional method of manual measurements with calipers, tracing out geometries with pen and cardboard, and even producing different prototypes to check for model accuracy. This method can take days, if not weeks, depending on the complexity of the part. However, thanks to 3D scanning technology, the lead times for digitizing parts can be reduced to minutes. 3D scanners allow gathering most reliable and precise data in a matter of minutes.
3D scanning technology is widely used in industrial quality assurance to measure geometric
dimension accuracy. Industrial processes such as assembly are complex, highly automated,
and typically based on CAD (computer-aided design) data. The optimal performance of this
process is guaranteed by quality assurance systems. Especially the geometry of the metal
parts must be checked in order to assure that they have the correct dimensions, fit together
and finally work reliably.
For this purpose, 3D scanners are applied to generate point samples from the object's surface which are finally compared against the nominal data. This process of comparing 3D data against a CAD model is referred to as CAD-Compare and can be a useful technique for applications such as determining wear patterns on molds and tooling, determining the accuracy of the final build, analyzing gap and flush, or analyzing highly complex sculpted surfaces
A 3D scanner is an excellent tool for museum curators, researchers, and archeologists to capture, study, and restore historical
artifacts and art pieces. Traditionally, plaster casts were used to create replicas of original artifacts in case of damage or robbery.
However, this process is not only time-consuming but also could damage the original artwork. A 3D scanner enables quick,
precise replication without any direct contact with artifacts. Once they are scanned, whether pieces of bones, delicate ornaments ,
or even entire archeological sites, 3D data can be permanently saved for various uses. For example, museums can use 3D data to
magnify and display 3D images of historical artifacts for visitors to learn about them.
A 3D scanner constructs virtual 3D images that can be used for characters or artifacts in movies, virtual reality (VR), or games. Creating complex objects manually
can be costly and time-consuming. 3D scanning technology is increasingly used in entertainment industries to create special effects by simply scanning an
object or a person.
When a designer wants to make changes in the original design by adding new colors or patterns, a 3D scanner enables production of precise 3D data of the
object without using a CAD process. Afterward, 3D data can be easily turned into an actual object through 3D printing. 3D scanning can also allow a designer
to quickly visualize how individual furniture items might look arranged in a room by scanning and virtually placing them.
A 3D scanner can be used to design customized wearable items, such as eyeglasses, hats,
wigs, and face masks, by capturing detailed facial data (e.g., nose bridge width, facial width,
head shape). By scanning body parts, more wearable items, such as shapewear, shoes,
insoles, or wristbands, can be readily designed for greater customer satisfaction.
3D figurines/selfies are a great way to capture special memories in life. They are also excellent gifts for special events for your loved ones!
Full-body scanners capture detailed data on the human body, which can be used for personalized reports for fitness tracking. It can also provide information about posture and body balance. A 3D body scanner is becoming an excellent tool to monitor personal health and fitness.
