What is the best 3D scanner?

Many different types of 3D scanners exist, from desktop 3D scanners to handheld 3D scanners and advanced metrology systems. 3D scanners serve an extremely wide range of applications, from reverse engineering to 3D body scanning or even forensic investigations.

However, given the low number of reliable 3D scanner reviews, it can be challenging to find the best 3D scanner. It can also be complex to know what kind of 3D scanner to get based on your application. A $2,000 3D scanner won’t be sufficient for part inspection, and a $60,000 3D scanner would be overkill if you don’t need the precision.

With that in mind, our goal is to offer an overview of the best 3D scanners in different categories. We broke down our best 3D scanner picks into actionable selections:

• Professional: A mix of the best desktop and handheld options for professionals
• Affordable: Entry-level 3D scanners for makers with prices starting at around $400

Metrology 3D scanner selection

3D metrology is the process of acquiring highly accurate physical 3D measurements of an object. The result is a digital 3D model that users can analyze or retro-engineer.

Take quality inspection, for example. Professionals can compare the 3D scan to a reference CAD model to make sure the object respects established norms and standards. 3D metrology helps ensure product quality while saving time and, thus, lowering costs.

Handheld 3D scanner selection

Handheld 3D scanners have been gaining a lot of popularity over the past few years. They offer various benefits over other types of 3D scanners:

• Ability to access hard-to-reach places
• Relative ease of use
• Portability

Their versatility makes them suitable for a wide range of industries, including automobile, aerospace, engineering, and design, and some can even be used for 3D body scanning.

SLAM 3D scanner selection

SLAM (Simultaneous Localization and Mapping) technology allows a device to position itself and navigate through a given space based on its surroundings. Sometimes called CML (Concurrent Mapping and Localization), it was initially developed for robots and autonomous appliances.

In 3D scanning (mobile mapping), SLAM algorithms combine and use the sets of data collected from one or more sources to track the scanner’s position, all while building up an accurate, complete 3D point cloud of the surrounding environment.

SLAM-based 3D scanners can work in extremely remote locations where GPS or GNSS signals are unavailable, and make it easy to quickly 3D scan large areas like building sites and underground caves.

TLS (Terrestrial Laser Scanner) selection

Terrestrial laser scanning (TLS) is a form of 3D scanning in which tripod-mounted laser scanners are used to capture large objects and environments. The technique is widely used in construction, surveying, forestry, and other disciplines.

Also known as long-range laser scanning, TLS involves deploying a scanner in a static location, whereas other laser scanners may be handheld or mounted to vehicles to capture data from a greater number of vantage points. TLS produces more accurate scans than mobile scanning — at the expense of speed and simplicity.

These 3D scanners are often generically called LiDAR scanners, though terrestrial scanners aren’t the only type of scanner to use the technology.

Desktop dental 3D scanner selection

Bit by bit, dentists are beginning to replace traditional methods with digital dentistry. This involves the use of digital capture, digital design, and digital production technologies to improve the speed, accuracy, and profitability of dental practice.

A key part of digital dentistry is the use of 3D scanners, which capture 3D shapes using a combination of cameras and light projection before transferring the result to a computer.

Desktop dental 3D scanners capture dental models or impressions (negative imprints of a patient’s teeth and gums) and are usually used in a laboratory setting.

Jewelry 3D scanner selection

A popular use of 3D scanning technology is jewelry 3D scanning. This is the process of 3D scanning jewelry, precious metals, and gemstones with the goal of creating a digital copy of the original object. The digital twin can be used for many purposes, such as repairing or duplicating a valuable item.

3D scanners have been adopted as a supplementary tool by traditional jewelers, but the technology has also allowed newcomers to enter the field, many of which have combined 3D scanning with jewelry 3D printing.

Most jewelry 3D scanners are enclosed or partly enclosed desktop machines that offer ideal lighting conditions. Desktop jewelry 3D scanners almost always feature an automatic turntable, or auto-rotating table, on which the piece of jewelry is placed to be scanned.

3D body scanner selection

3D body scanners are designed to capture your full body in 3D. The result is a 3D model (or 3D avatar) of your exact body shape with accurate data such as body measurements, posture analysis, textures, …

Originally developed for the fashion industry as fast and accurate 3D measurement solutions, 3D body scanners are now used in various other fields such as healthcare, 3D figurines and 3D photos, fitness, and entertainment.

To obtain a full-body 3D scan, the customer or patient holds a pose for a few seconds, which is the time it takes for the 3D scanner to capture images from all angles. The 3D software then reconstructs the final 3D model of the body by “stitching” all of the images together, generating a highly detailed 3D model. Models can have colors and textures depending on the type of body scanner.

Which 3D scanner is the best for me?

3D scanning can be used in a large variety of fields. For every application, the features necessary to generate a great 3D model are different. The 3D scanner must be chosen according to your desired use and results.

What the best 3D scanner is for you will depend on many factors, detailed below.

3D scanning field of application

The first thing to take into consideration is the field in which the 3D scanner will be used. It could be for example:

Professional use

• Small objects: dentists, jewelers, and other professionals can use 3D scanning to capture small pieces.
• Big objects: professionals such as architects and archeologists might need to 3D scan large objects such as statues, archeological fields, or buildings.
• 3D body scanning is increasingly used in various professional fields such as healthcare and 3D figurines.

Personal use

• Occasional scanning: A person might need to use 3D scanning on rare occasions or maybe just one time.
• 3D scanning on a regular basis: You can use 3D scanning for various things from making personalized objects to making a replica of yourself, friends, or family members.

Type of 3D scanned object

Dimensions and distance of the object (scan area and scanning range)

The “best 3D scanner” will depend on the dimensions and the distance of the objects you wish to 3D scan. A desktop 3D scanner can’t 3D scan a 2-meter-tall statue, and a handheld 3D scanner might not be the best option to 3D scan a very small and precise piece.

Surface of the object

Not every 3D scanner is able to capture colors. For color capture, you need a scanner with photogrammetry.

It can also be challenging to capture objects with black, shiny, or reflective surfaces. However, as 3D scanning OEMs fine-tune their technology and hardware, such surfaces are becoming less and less of a challenge. For cases where it is a challenge, it is always possible to use a white mattifying spray.

Desired resolution

Not all 3D scanners offer the same level of resolution. Therefore, depending on the quality you need, some 3D scanner models are more adapted than others. Reverse engineering requires high resolution and precision, for example.

3D scanner recommendations

Desktop 3D scanners

Desktop 3D scanners can be ideal for both professionals and hobbyists that need to scan small parts. They tend to be more accurate since you aren’t holding and moving the 3D scanner around yourself.

Also, many desktop 3D scanners come with (or at least optionally) an automatic turntable, which makes it much easier to get clean 3D scans.

Handheld 3D scanners

Handheld 3D scanners, a.k.a. portable 3D scanners, are versatile and can 3D scan small to very large objects. They also enable users to 3D scan hard-to-reach places. The precision and the ability to capture color and texture will depend on the 3D scanner model.

3D body scanners

3D body scanners have applications in numerous fields.

• Professionals: professionals might want to 3D scan a person to make a 3D figurine, prepare for a surgical intervention, follow-up on a pregnancy or skin conditions, etc.
• Individuals: 3D body scanners can help with fitness goals and personal shape. These 3D scanners usually can’t capture color and texture but offer a high resolution.

3D scanning mobile apps

3D scanning mobile apps are ideal for occasional users that are not willing to or are unable to invest in a 3D scanner. They are not as precise as most 3D scanners, but mobile apps are a great way to get familiar with 3D scanning.

3D scanner price

3D scanner prices can range from just several hundred dollars to over $100,000.

Desktop 3D scanner price

Desktop 3D scanner prices vary a lot from one model to another. It can start at a few hundred dollars and can top out at around $50,000 for the more advanced 3D scanners. More industrial-grade, robot-mountable scanners can cost double.

Handheld 3D scanner price

The handheld 3D scanner price range is very wide. A professional handheld 3D scanner can start at around $5,000 and can reach up to over $70,000 for very high-end and advanced 3D scanners.

There are plenty of great entry-level options for a couple of thousand dollars. Mid-range handheld 3D scanners tend to cost between $10,000 and $30,000.

Industrial 3D scanner price

Industrial 3D scanners generally offer more cutting-edge features and higher precision. Hence, their prices can be pretty high, ranging from $10,000 for the simplest ones to more than $100,000 for the most evolved ones.

3D scanning applications

There are many reasons to buy a 3D scanner, for various industries and applications.

Reverse engineering

Reverse engineering, also known as retro-engineering, is the process of extracting information from an object or process and studying it. 3D scanners can be used to capture all the parts of a disassembled object to create a 3D model. The user will then be able to digitally study it in 3D afterward.

Overview of 3D scanning technologies

Photogrammetry

Photogrammetry consists of taking measurements from photographs to recover the exact positions of surface points.

The principle of photogrammetry is to analyze several photographs of a static subject, taken from different viewpoints, and to automatically detect pixels corresponding to the same physical point.

Photogrammetry enables scanners to capture an object’s color (a.k.a. texture). This technology also often serves to detect positioning markers (sticky targets placed on or around the object to help the scanner precisely align scans together).

Structured light

3D scanners using structured light project a series of linear light patterns onto an object.

The system is then able to examine the deformations of each line and to calculate the distance between the 3D scanner and the object’s surface. With this data, the software is able to build an accurate 3D model of the object.

Triangulation

A 3D scanner using triangulation technology will project a laser beam on the object’s surface and measure the deformation of the laser ray (similar to structured light, but with one or more lasers).

Contact

Contact 3D scanners probe the subject via physical touch. A touch probe moves along an object’s surface to record 3D information.
