What Is a 3D Model Scanner and What Are Its Uses?

Are you wondering if a 3D model scanner is a good business investment?

The 3D scanner market will likely reach $1.6 billion by 2028. Demand for 3D scanning technology from different industries fuels the market growth. This unprecedented growth can lead you to hop in the trend.

However, you must understand the technology behind 3D scanners to maximize their benefits. Keep on reading below for a guide to 3D model scanners and their many uses.

What Is a 3D Model Scanner?

A 3D model scanner is a mechanical device that generates 3D scans. The scans feature a three-dimensional image of the object’s surface.

3D scanners capture the geometry of the subject’s surface. Tiny polygons or triangles make up the 3D scan to form a 3D model. Regardless, it works like a video camera by taking shots of a particular object.

Since it’s like a video camera, a 3D scanner is non-destructive and doesn’t need to touch the object. Some 3D scanners use laser light technology. These allow you to capture the object’s exact shape and size for 3D digitization.

What Is the 3D Scanning Process?

The 3D scanning process has two popular methods. These are laser triangulation 3D technology and photogrammetry 3D scanning technology.

In laser 3D technology, the scanner uses triangulation. It determines and values the data points’ location on the object’s surface.

The scanner uses sensors to project a single laser line onto the surface. It also has angled sensing cameras for observing the shape of the laser line. The scanner determines the angle between the sending cameras and the laser source.

After calibration, it uses the data to triangulate and value every pixel along the laser’s length. The triangulation happens while the laser sweeps across the surface.

Meanwhile, photogrammetry involves taking many shots or movements. Its goal is to record the object’s surface geometry. It’s a technique that aligns the object’s measurements to create remarkable accuracy.

Unlike 3D laser scanning, photogrammetry supplements the scanner to ensure exact measurements. It uses a camera that takes images from different perspectives. The camera can either be the following:

• Manual
• Digital
• Integrated

Special software analyzes the images and the typical features and fuses them.

Different 3D Model Applications: The Medical Industry

What are the different uses of 3D scanning? This technology is changing the healthcare industry in various ways. Hospitals and other medical facilities integrate 3D scanning into treatments.

Doctors perform body scans using scanning technology to get faster results. Hospitals use either handheld or stationary scanners that gather data. It allows faster pre-op and post-op patient scan comparisons without compromising accuracy.

Medical facilities also use a 3D model to make implants, braces, and prosthetics. The scanners help customize wheelchairs and other equipment to deliver custom solutions.

After capturing the images, hospitals send the data for manufacturing. They do so using a 3D printer or milling machine.

Engineering and Industrial Design

Engineering and industrial firms also use 3D scanners to save time and resources. They use the scanners in the following processes due to their accurate data:

• Design
• Testing
• Development
• Launching stages

Stationary 3D scanners are flexible since they can scan different-sized objects. Some of these include trucks, planes, and other large items. The scanners are simple to operate and need minimal supervision.

For smaller objects, handheld 3D scanners work best. Operators can take images from different angles and capture high-precision geometries.

The flexibility extends to the 3D scanning software. Companies pair the scanners with software for analysis, printing, or reverse-engineering. 

Meanwhile, next-generation 3D scanners like the Go3DPro offer accurate image-capturing features.

Archaeology

3D scanners are also making waves in archaeology and heritage preservation. Schools and museums use 3D scanning to create digital replicas of historical artifacts.

Archaeologists use scanners to get accurate images. As a result, they can create exact depictions and restorations. They use these images for launching online exhibits.

They can use the data to determine what an artifact looked like during its time.

Through digital data, they can document the scans faster. They can share findings with other groups. The best part is publishing them on websites to educate everyone.

Forensics

The police force also uses 3D scanners for gathering evidence. Forensic experts use handheld scanners to scan images in a crime scene. The scanners work both indoors, outdoors, and under direct sunlight.

The scanners yield accurate results in minutes, crucial in time-sensitive cases. The police and insurance companies can use them as evidence in court due to their accuracy.

Art and Design

The art, design, and entertainment industries also benefit from 3D scanning. Video game creators use 3D scanners to develop immersive and realistic experiences. They scan faces or people to create accurate character depictions.

3D scanners offer a safe way of capturing images from difficult places. Artists also use them to scan small items with intricate details. They create accurate 3D models of jewelry and interior décor pieces.

Tips for Choosing a Good 3D Model Scanner

Different factors affect your choice of a 3D model scanner. The first consideration is the scanner’s resolution. After all, the scanner should give you clear images regardless of your position.

Next, determine the size you need. Handheld scanners offer more mobility, while stationary ones work best on larger objects.

Where will you use the scanner? Are you scanning small to medium-sized items or large ones? Handheld scanners are perfect for medical applications like body scans.

For scanning basic shapes or vases, get a scanner with a single-axis turntable. For objects with angled or recessed features, buy a multi-axis one instead.

Find a reputable supplier. Check the company’s experience and track record. Read customer feedback on the quality and performance of their scanners.
