Best 3D Scanner - The Top 10 3D Scanners for 2023 [Reviews]

Much like a regular scanner, laser scanning 3D uses various methods to analyze a physical object and then relay that data to a computer to create digital 3D models. The 3D digitizer process might be automatic or users might need to complete the model to their requirements by using software. The aim is usually to get an accurate model to the right standard and format, ready for 3D printing, for virtual reality applications or other purposes. 

Such scanners are used in many professional industries, but with advances in home 3D printing, there are now also a good variety of home options. They are sometimes called portable 3D scanners or handheld scanners if they’re designed as such. These allow you to easily scan small to medium-sized objects for 3D printing.

Some come completely assembled while others, like 3D printers themselves, you’ll have to put them together by yourself. The benefit for those that are good with that type of thing is it reduces the price and allows for easier upgrades and modifications.

Scanning is typically done using laser triangulation or various forms of structured light to surround the object and measure its 3D dimensions or ‘geometry’. High-quality 3D scanner camera lenses also capture the color and surface texture of the object. Using accompanying or third-party software, the model can then be scaled up or down, or completely modified. 

It’s never been easier to scan 3D objects!

How Do 3D Scanners Work?

So, how do you scan 3D objects into a computer? Whether it’s on an industrial scale, at a small business, or on a desk at home, 3D scanners all share similar characteristics in the way they work. 

The majority use laser and/or white light technology and cameras. The physical object is placed in a bed, tray, or suitable location. Electromagnetic light bounces off the object, measuring its circumference, full dimensions, and all its finer details.  

Depending on the scanner it may use multiple light sources, cameras, and other tech to aid this process. The collected data is called a point cloud, which refers to the number of points captured by the laser. 

The more points collected the more accurate the scan. A high-resolution scanner can capture hundreds of thousands of points in seconds and reach millions overall. The whole process only takes a few minutes.

While the light tends to be a measure of the object’s geometry, HD cameras tend to capture the surface detail and color.

The data recorded can then be fed into a computer-aided design program or similar software for inspection and manipulation. E.g. if you’re planning to use it for 3D printing, the model might need scaling up or down, hollowing, have added support structures, be re-colored or have brightness/contrast changes, etc.

There are, of course, different types of 3D scanner and scanning technology. So, let’s take a closer look at each one:

Types of 3D Scanners

There are several 3D scanner types. Before making your decision check out the section below:

Handheld vs Stationary

Handheld and stationary 3D scanners often use the same technology and can overlap in their functions. The difference lies mainly in the design.

 A handheld scanner has a grip and lets the user move around the object themselves to capture it at every angle.

A stationary scanner has to be positioned in front of the object, which is typically placed on a rotating plate and captures it as it spins 360 degrees. The user may have to reposition the object several times to capture every angle. 

Newer designs are becoming smaller and more easily portable.

Laser Triangulation

The most common technology used in 3D scanning is laser trigonometric triangulation. It records millions of different points on the surface of the object to build an accurate overall polygon mesh. These are common in handheld options and industrial-grade scanner machines. They can also work long-range and for laser-tracking objects.

Structured-Light 3D Scanners

Similar and often used interchangeably with laser triangulation, structured light or ‘white light’ projects itself in a grid-like pattern over an object. It can then measure the structure of that grid as it applies to the object by using sensors/3D scanner cameras and triangulation.

Long Range

Longer range scanners use phase shift or pulse technology that can capture millions of points while rotating 360 degrees with the aid of mirrors. This is more commonly used to scan large objects like cars or buildings.

They might also use ‘time of flight’ technology that measures the distance of an object in relation to the speed of light and the time it takes for it to return to a sensor.

This is less relevant for everyday 3D scanning and printing.

3D Scanning Applications

There are many different applications for 3D laser scanning - from those for 3D printing at home, to prototyping, industrial scale medical supply production and even architecture. 

Hobbyist 3D printing

Cheaper 3D scanners are typically used by home users for scanning simple objects and 3D printing them for fun. 

Medical

The medical field and dentistry commonly use 3D scanning to create implants and aids to serve their patients’ needs. For example, scanning people’s feet with a high-quality 3D scanner allows for the creation of orthotics (shoe inserts). It is also used in the creation of prosthetics.

Virtual Engineering

Industrial 3D scanners are used both in the creation and quality control of cars, planes, and even aerospace. It ensures existing parts are as accurate as their original models and that new viable parts are made.

Reverse Engineering and Repairs

From the home computer desk to the manufacturing floor, 3D scanning allows users to reverse engineer or copy existing objects. Saved models also allow for the reconstruction of damaged objects.

Virtual Reality

From creating realistic 3D worlds to the people that occupy them, 3D scanning devices are integral to the growing virtual reality industry. This ranges from AAA video games, virtual cinematography, and computer-generated imagery (CGI), to virtual tours and office meetings. It is also a side industry to motion capture.

Forensics

CSI has come a long way. Forensic experts nowadays don’t just have to rely on memory, photos, and evidence of a crime scene. They can capture the entire location in a full 3D model for closer inspection and for running through different scenarios.

Archeology and Archiving

From museums to libraries, 3D scanning is being used to log and preserve everything from artifacts to digitizing books. This also gives experts and the public remote access.

Architecture

3D scanning can also help architects map the areas they will be designing their buildings in, take inspiration from existing architecture, and aid in building miniatures/prototypes. 

What Should I Know Before Buying a 3D Scanner?

Before you buy a 3D scanner, there are several things to consider: 

  • your budget 
  • what you’ll actually be using it for 
  • it’s speed and accuracy
  •  the device’s other features.
3D Scanner Cost

3D laser scanner price ranges vary greatly. On the cheaper end, you may be able to pick one up for home for just shy of $300, like the XYZprinting 3D Scanner 1.0 A. However, if you want the highest overall quality and the ability to scan small and large objects. Or, if you’re a professional and need a 3D part scanner in a field like medical implants or automotive parts, you’re looking at anywhere between $3,000 and $35,000.

Typically, it’s best to look for 3D scanners for sale online where you can find the best selection and prices.

3D Printing

While a dual 3D printer scanner combo is rare, if you want to scan models for 3D printing, you will need to make sure it has good accuracy and resolution. The software also must be able to export to a usable format. You will need to check your 3D printer and its own software to see what file types it accepts and then choose your scanner accordingly.

Fortunately, almost all of our 3D scanner reviews include devices that can export in common file types like OBJ and STL.

It’s typically only the more expensive scanners that are good for other applications, like VR, full-body scanning, architecture, and engineering.

Handheld vs Stationary

We already explained the difference, but basically, a handheld scanner is mobile, while the stationary one will require you to move and adjust the object. Neither is necessarily better than the other, it’s all down to your needs.

Speed

How fast is the scanner? Do you have a lot of spare time or require the job to be done as fast as possible? All 3D scanners will take a few minutes to complete, while many scanning complex objects in high resolution can talk half an hour or longer.

Accuracy and Resolution

Accuracy refers to how close to the object being scanned your digitized model will be, measured in millimeters. Therefore, the smaller the better. The term resolution may be used interchangeably with accuracy or refer to the resolution of any cameras being used as part of the scanning process. 

Generally, the lower the millimeter, the better. Other factors also play a role in overall quality, such as lighting conditions, color, and depth.

Object Size and Space

Some types of 3D scanners excel at scanning small objects while others are better at medium to large. Others are all-rounders. Before buying a scanner, you should decide the general size of the items you will be scanning. 

You will also need to make room for the scanner. Although all the products on our list are small and relatively portable, stationary scanners at least need a table to work from. Likewise, there will be a minimum and maximum distance the scanner must be in relation to the object being scanned. 

You’ll need more room when scanning larger objects in full.

Connected Devices

All 3D scanners need to be connected to a computer or device to help monitor the process and for saving the digital model. This is usually done via a USB or HDMI cable. You will need to check that your computer or laptop meets the minimum requirements for the scanning and modeling software. Also, make sure that you have a tablet to make real-time monitoring easier. 

Software

Your device will either come with its own software or a popular third-party program to aid the process and to help touch-up the model once it’s scanned. Different 3D printing software is better suited to different skill levels. Some programs have a lot of features for experienced users and others do most of the basic tasks automatically. Check our 3D scanner reviews to see the software each device comes with and how advanced and easy to use it is.

Overview of the best affordable 3D scanner options

Revopoint launched the POP 2 towards the end of 2021 after a successful Kickstarter campaign with the original POP. We reviewed the original POP shortly before this release, and it seems that some of the quacks (mainly software-related) we encountered have since been worked out. Their new software features a calibration process and a new “Wi-Fi host” mode.

The POP 2 is an interesting option for makers or beginners looking to learn more about 3D scanning. We wouldn’t particularly recommend it for professional use cases, though it can get the job done if you don’t need high resolution.

The Revopoint POP 2 can be used on a small tripod or as a handheld device, and is able to capture colors.

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.

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.

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).

FAQ

What is the most accurate 3D scanner?

The most accurate 3D scanners are metrology 3D scanners, which generally offer an accuracy of around 20 microns.

Is a 3D scanner worth it?

This is entirely up to how much you will be using your 3D scanner. We can however say that 3D scanning is an impressive technology that does help save a lot of time for product design, reverse engineering, part inspection, and many other use cases.

How much does a good 3D scanner cost?

Again, the definition of “good” is quite subjective in 3D scanning. Some of the best 3D scanners we have reviewed cost between $10,000 and $30,000. But a $5,000 3D scanner can do “good” if its specs meet your requirements.

Is 3D scanning expensive?

Not only is 3D scanning hardware generally expensive, but so are the necessary, professional software solutions. Sometimes, it’s a one-time fee for a permanent license; other times, a monthly or yearly subscription is the only way to access a software suite. And to run such software, you will likely require a powerful, monster of a PC with a lot of RAM and a high-end graphics card. You may also need to buy a tripod or turntable if they aren’t included in your 3D scanner package. All of this can quickly amount to several thousand dollars.

Day-to-day 3D scanning expenses can include cans of mattifying spray and rolls of adhesive markers if you need them. Other than that, aside from potential software subscriptions, there are no extra hidden costs.

The advantage of metal stamping over forging and casting is the lower weight and thickness of the resulting parts. The use of molds gives high accuracy and maximum compliance of the obtained parts with the specified characteristics, but does not completely exclude deviations and deformations. Which, in turn, can lead to difficulties in assembling finished products and reducing product quality. Therefore, constant quality inspection is a necessary part of production.

Having understood the problems of the manufacturer, ScanTech experts proposed to check the quality of stamped parts using the PRINCE laser scanner. The ability to switch blue and red laser modes allowed the device to combine the functionality of traditional portable and metrological 3D scanners. The mode of operation with an active beam of a red laser provides fast digitization of objects. In the case of increased requirements for accuracy and detail, turn on the blue laser beam mode.

technologies, types, how 3D devices work

Many digital engineering strategies for the future of development, manufacturing, quality control, and product release start with 3D scanning. 3D scanners work with advanced technologies and specialized software to create a tool that allows you to achieve revolutionary results. For those still working with power tools and traditional coordinate measuring machine (CMM) technology, 3D scanners serve as an easy gateway to advanced manufacturing and engineering strategies.

Read below to learn more about how 3D scanners work and what this technology can do, so you can start enjoying its benefits now.

What are 3D scanners?

A 3D scanner works by capturing data from the surface of a physical object to describe its shape in an accurate digital 3D format. Unlike CMM measurement data, high quality 3D scan data is used for more than just inspection and dimensional analysis. The data obtained by non-contact measurement allows faster and more accessible digital analysis and inspection using a visual, in-depth method of examination.
3D scanners are also used to replicate parts in reverse engineering, check the fit, shape and function of components in remote locations, and check CAD models of 3D printed parts. 3D printers can use 3D scan data to create physical objects.

What is 3D scanning?

3D scanning is the process of collecting data about the surface of an object in digital format to determine its shape, allowing users to either reproduce the part by reverse engineering or verify it by dimensional analysis.

To do this, operators use scanners that use lasers, light or sensors to determine the surface of the scanned object and assign data points to this surface. These data points will eventually recreate the . Depending on the type of laser, light, or sensor used, the level of detail and scanning performance may vary.

3D Scanning Technologies

Photogrammetry

Originating from photography, photogrammetry is an incredibly useful technology in various fields. This technology allows you to take multiple images taken at different positions and triangulate points on those images to determine their location in 3D space.

For example, cartographers use this technology when compiling maps. When it comes to hard-to-reach places like mountains, surveyors can use photogrammetry to take measurements.

Many modern technologies use photogrammetry, and the quality of the images is the main factor determining accuracy. If the images are poor quality, there will be holes in the grid. The more images you can get, the higher the scan accuracy will be.

Shining 3D offers a solution - DigiMetric Photogrammetric System.

Structured Light

This technology is created by applying geometric patterns to an object while simultaneously capturing an image with a camera. In this case, the camera registers the deviation of the image.

Based on this template offset, all existing points can be located. It is necessary to conduct many scans from different positions, and then merge them until the mesh is 100% complete. Computer programs automatically combine all images to form a complete grid.

3D laser scanning method

3D laser scanning data acquisition

3D laser scanning process

The object to be laser scanned is placed on the scanner platform. Specialized software directs the laser probe over the surface of the object. A laser probe projects a line of laser light onto the surface, and 2 sensor cameras continuously record the change in distance and shape of the laser line in three dimensions (XYZ) as it passes along the object.

Acquired data

The shape of an object is displayed as millions of dots, called “point clouds”, on a computer monitor as the laser moves around, capturing the entire shape of the object's surface. The process is very fast and laser scanning is more accurate than infrared.

Point cloud data for inspection

If the data is to be used for inspection, the scanned object can be compared with the designer's nominal CAD data. The result of this comparison is provided as a “color map deviation report” in PDF format, which clearly describes the differences between scanned data and CAD data.

Reverse engineering CAD model

Laser scanning is the fastest, most accurate and automated way to obtain digital 3D data for reverse engineering. Again, with the help of specialized software, point cloud data is used to create a 3D CAD model of the geometry of the part.

The CAD model can accurately reproduce the scanned object, or the object can be modified in the CAD model to correct imperfections.

Types of 3D scanners

Active scanners emit some radiation or light. The scanner detects the reflection to collect information about the object. Let's take a look at the active views of 3D scanners below.

3D Laser Scanners

3D Laser Scanners use a process called trigonometric triangulation to accurately display a 3D shape as millions of dots. Laser scanners work by projecting a laser line or lines onto an object and then capturing its reflection using one or more sensors.

The sensors are located at a known distance from the laser source. Accurate point measurements can be made by calculating the angle of reflection of the laser light.

Laser scanners are very popular and come in many designs. These include handheld, manipulator-based, CMM-based handheld devices, long-range trackers, and long-range single-point trackers.

Benefits of 3D laser scanners:

  • Ability to scan complex surfaces such as shiny or dark surfaces.
  • Less sensitive to changes in lighting conditions and ambient light.
  • More accurate data, available for inspection.

Projected or structured light 3D scanners

Historically known as “white light” 3D scanners, most structured light 3D scanners today use blue or white LED projected light. These 3D scanners project a pattern of light onto an object, consisting of stripes, blocks, or other shapes. A 3D scanner has one or more sensors that look at the edges of these patterns or structural shapes to determine the object's 3D shape.

Using the same trigonometric triangulation method as in laser scanners, so the distance from the sensors to the light source is known. Structured light scanners can be mounted on a tripod or hand held.

Benefits of Structured Light 3D Scanners:

  • Very fast scan times of only 2 seconds per scan.
  • Versatility - multiple lenses for scanning small and large parts in one system.
  • Portability - handheld systems are highly mobile.
  • Eye friendly for 3D scanning of people and animals.
  • Color 3D scans available.
  • Various price ranges from inexpensive to expensive depending on resolution and accuracy.

Coordinate Measuring Machine (CMM)

Coordinate Measuring Machine (CMM) is mainly used for parts inspection. The machine can be controlled manually or through autonomous control by software and computers. Measurements are determined by attaching a sensor to the machine. The sensor usually has a small ball at the end of a shaft of known diameter. The CMM is then programmed to make contact with the part. When the machine senses contact with the probe tip, a value in XYZ space is measured. The most common type of CMM is the bridge type, which has 3 x, y, and z axes. The attached sensor system can be rotated to provide an additional 3 xyz axes, giving a total of 6 degrees of freedom (DOF).
For very precise measurement of parts down to a few microns, CMMs are usually installed in a controlled room.
The room includes a reinforced floor, controlled humidity and temperature, and isolation from vibration and other forces that may affect accuracy.
In addition, most CMMs have a large granite table surface that is perfectly flat. Details are fixed on a granite table in such a way as to exclude their movement during the measurement process.
Advantages of CMM:

  • One of the most accurate way to measure an object
  • With the appropriate machine, both small and large parts can be measured
  • There are industry standards and certifications for measurement and software
