3D scanning for Metrology: Guide and product selection

What is 3D metrology?

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

In the case of quality inspection, for example, the 3D scan can be compared 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.

CMMs– coordinate measuring machines– have traditionally been the most common type of hardware used for precision measurement. However, advances in 3D scanning technology are making 3D scanners increasingly popular for metrology as well, as they are faster and more cost-effective.

In this guide, we offer a comprehensive overview of some of the best metrology 3D scanners available on the market, covering different types of hardware (stationary, handheld) and price points. We also provide basic insight into 3D metrology software, which is as equally important as the hardware side of things.

Note: Not sure if you need an industrial metrology-grade performance? Take a step back and learn about other types of 3D capture solutions (jewelry 3D scanners, dental solutions, SLAM, …) in our all-round 3D scanner buyer’s guide.

Types of metrology 3D scanners

Handheld metrology 3D scanners

Handheld 3D scanners are convenient, versatile systems that grant access to hard-to-reach places (e. g. car interiors). They often feature several modes for users to adapt to small, medium, or large-sized parts.

Using a handheld 3D scanner is comparable to recording a video or painting with a brush; the subject must be captured from all angles.

Stationary metrology 3D scanners

A stationary 3D scanner is similar to a camera on a tripod. For small or medium-sized objects, these scanners are usually paired with an automatic turntable for smoother workflows.

They can also be mounted onto an automated station. Such systems generally move the scanner up and down along the Z-axis while the object to be scanned sits onto an attached turntable.

Stationary scanners are often more accurate solutions due to their fixed setup but are impractical for large objects or infrastructures. That said, some are robot-mountable.

Automation in metrology with robotic arms

Many metrology 3D scanners, mostly in the stationary category, are designed to be mounted onto an industrial, robotic arm depending on specific needs.

Here is an example from Scantech:

These 5-axis or 6-axis arms eliminate human errors and speed up the scanning process. Robotic 3D scanning arms are often used in assembly lines.

High-end industrial 3D metrology systems

For our main selection, we didn’t include high-end systems that are destined for heavy industrial applications. They can’t be compared on the same level as the scanners from our main list, whether it’s in terms of accuracy, pricing, software, or automation.

Several leading brands like Hexagon and GOM (which is now part of ZEISS) provide extremely accurate, automated 3D scanning solutions for industrial assembly lines.

3D scanner vs CMM

CMM stands for coordinate measuring machine. This type of device uses a probe- either a physical, surface-touching probe or a light/laser source–to measure an object’s geometry. CMMs can be operated manually or computer-controlled.

These machines are highly accurate but are relatively slow at capturing data and only acquire a certain amount of points. A standard CMM captures several hundred points, in contrast to 3D scanners which acquire hundreds of thousands or millions of points.

Hence, CMMs are mostly used for targeted inspection rather than for providing full 3D models of objects, in which case 3D scanners are the best option.

The main advantages of 3D scanners over CMMs are:

  • Speed: A 3D scan can be processed in a matter of minutes, while CMMs require more time.
  • Automation: 3D scanning systems are much more compatible with industrial environments such as assembly lines.
  • Scope: 3D scanners capture exponentially more information. This can allow engineers and designers to understand what the root cause of a potential part deformation is rather than simply identifying its existence. They can also scan much larger parts than CMMs, which have a fixed frame/volume.
  • Flexibility: It is easier to relocate a 3D scanner and use it at several workstations to adapt to different production needs. CMM machines generally stay in one place and take up a large amount of space.
  • Non-intrusive: While coordinate measuring machines don’t necessarily all need to physically touch the object, they do get close to the object, which can be a problem in some cases. 3D scanners can capture data at a safe distance.
  • Price: 3D scanners are generally less costly acquisitions than CMM machines.

All of this being said, CMMs and 3D scanners can be complementary. CMMs are hard to beat when it comes to measuring holes and complex, intricate details.

By using both a CMM (such as a handheld probe) and a 3D scanner, it is possible to reach a high level of accuracy.

Which industries use metrology and why?

Integrating 3D metrology directly in the value chain of any industry ensures high part quality without interrupting the production line.

These are some of the many industries that take advantage of 3D metrology:

  • Aerospace and automobile
  • Electronics
  • Power and energy
  • General manufacturing
  • Medical
  • Tooling

The top application for 3D metrology is part inspection within general quality control processes. It is essential for any business to oversee that their manufactured goods are up to standard.

This is true whether these goods are simple household objects, like a microwave knob, or crucial airplane parts that must be 100% standard and safe.

Accurate 3D measurement data also provides the option to reverse-engineer replacement parts and make quick repairs.

Overall, using 3D metrology ensures fewer errors in production, saving both time and money.

Metrology software for inspection

A 3D scanner is only as good as the software it works with. For clarity, we can distinguish two kinds of software:

  • Base software to operate the scanner: This is typically proprietary software (e.g. Artec Studio) that is included with the scanner to convert the data points and clouds into a 3D mesh of the scanned object. It offers basic functionalities such as mesh alignment and hole filling, but usually won’t be enough to perform advanced inspection and quality control operations.

This can be sufficient depending on the end-use of the scan, but when it comes to metrology, additional software is often needed.

  • Software for inspection: For 3D metrology, engineers and designers use specific inspection software or modules with additional functionalities and power. Indeed, the primary goal (among others) is to compare the 3D scan to a reference CAD file. The software must be able to do that in order to find potential discrepancies and deliver deviation maps or reports.

3D inspection software: what’s available?

In most cases, manufacturers either provide their own software or recommend third-party suites.

  • Proprietary software: The manufacturer can develop their own separate inspection software, like GOM with GOM Inspect, which is a reference in the industry. Other proprietary inspection software suites for 3D scanners include:
    • Creaform VXelements and VXinspect module
    • FARO CAM2 2020
    • ScanTech ScanViewer
    • PolyWorks Inspector
  • Third-party software: Manufacturers can recommend or bundle in a particular third-party software. Some of the most renowned, “universal” metrology 3D scanning software suites include:
    • 3D Systems Geomagic Control X
    • Verisurf Inspect
    • Siemens NX
    • GOM Inspect (comes with GOM scanners but is also recommended by other manufacturers)

Of course, there are exceptions to this distinction. Some manufacturers directly include inspection-type functionalities within their base software, like ScanTech with ScanViewer or GOM with GOM Inspect.

Conversely, sometimes inspection software is capable of serving as base software by importing and processing raw 3D scanning data, too.

3D scanning software pricing

Metrology and inspection software prices are quite high, sometimes even higher than the hardware itself. They can cost anywhere from several thousand dollars to over $30,000 and are not always included in the 3D scanner’s price, so it is something to watch out for when choosing a scanner.

If you already have a license for a specific inspection software suite, you can also check which scanners are compatible with it.

What specifications to look for in a 3D scanner?

There are several specifications to look into before purchasing a 3D scanning solution for metrology.

Accuracy

Accuracy defines how close a measurement is to its true value. This is of utmost importance for metrology applications. Often, manufacturers provide two different kinds of accuracy specifications: single scan accuracy and volumetric accuracy.

Light source

3D scanners use different kinds of light sources to capture 3D images: laser lines and crosses, which are typically red or blue; or LED light patterns, which are usually white or blue.

Generally, the more lines or lasers a 3D scanner has, the faster it will be at 3D scanning.

Resolution

Resolution is typically measured in point-to-point distance, and sometimes in points per scan.

As is the case with images, the higher a scan’s resolution is, the more details will be visible and the crisper the results will be.

There are two different kinds of resolutions: measurement resolution and mesh resolution. Mesh resolution is the most important kind to consider, as it will be the resolution of your final 3D model.

It may at times be unclear which resolution manufacturers are referring to in their product specifications.

Speed

Data acquisition speed can be expressed in point measurements per second, frames per second, or seconds per scan.

Software

Some 3D scanner manufacturers develop their own software, while others have partnerships with existing, leading 3D scanning software brands.

It is also important to keep in mind that 3D scanning software always requires powerful laptops in terms of RAM, graphics cards, etc. If you are not well equipped, you may need to allocate several thousand dollars of your budget to a new PC.

Range and field of view

Evidently, it is inefficient to 3D scan a large object with a 3D scanner that has a small range or field of view. Hence it is mandatory to see if a scanner’s range is compatible with what you are planning on 3D scanning.

Some 3D scanners offer multiple 3D scanning modes to adapt to different object sizes.

Marker placement

Markers are small, adhesive “targets” that aid 3D scanners in positioning the data that they have acquired. In other words, they help the scanner align the different captured frames together, relatively to each other and in space, to form the 3D model.

In order to enhance their global accuracy, a number of structured light or laser 3D scanners integrate marker acquisition with photogrammetry technology, through dedicated cameras.

They are in a way “hybrid” 3D scanners, explaining why some metrology 3D scanners require the user to place markers on the object to be scanned or its environment, especially for large-sized objects (over 1 meter).

Metrology 3D scanner price

The price for a metrology 3D scanner largely depends on its accuracy, software, and other factors. For heavy industrial applications, the price for an appropriately accurate scanner and software can go well over $100,000.

For less demanding use cases, the price for an entry-level metrology 3D scanner can start at around $15,000.

FAQ

How much is a metrology 3D scanner?

Metrology-grade 3D scanners generally cost between $20,000 and $50,000. Industrial, robotic automated systems can cost over $100,000.

How accurate is 3D scanning?

Currently, accuracy can get all the way down to 0.004 mm- 16 times thinner than an average human hair.

What is the maximum size of objects you can 3D scan?

The maximum scanning area depends on the scanner itself. Keep in mind that the bigger the scan, the less accurate the result will be (linearly).

Can I do metrology with a handheld scanner?

It is possible to do metrology with a handheld 3D scanner. For repeated industrial applications, however, stationary or automated scanners are preferable.

How much time does it take to 3D scan an object?

Depending on the 3D scanner’s speed and the object’s complexity and size, it can take anywhere from less than a minute to several dozen minutes. Software processing adds a bit of time to the total.

Can I scan shiny objects? Can I scan dark objects?

Shiny and dark objects are hard to 3D scan, regardless of the 3D scanner’s quality. Special sprays and techniques exist to overcome this obstacle.

Review of 3D scanners for metrological control / Sudo Null IT News

In this article we will talk about optimizing quality control processes using 3D scanning, about the design and principles of operation of metrological 3D scanners. Using real examples, we will show the effectiveness of using equipment for solving various problems. After reading the review, it will be easier for you to navigate among a large number of models on the market and determine the criteria for choosing the right device.

Introduction

Every year the industry produces more advanced instruments and devices. Machine parts often have a complex geometric shape, are in close interaction with each other. In order to ensure the smooth operation of the mechanisms, it is necessary to match the shapes, sizes, assembly accuracy and other parameters. Quality control in mechanical engineering was carried out using various technologies, including using coordinate measuring machines (CMMs). However, scanning is by far the most efficient method in terms of the ability to capture data for measurements and the speed of information processing.

Capabilities of 3D scanners


Source: solutionix.com

3D scanners cope not only with smooth surfaces, but also with complex areas: corners between edges and faces, depressions, holes. An important advantage of the devices is the non-contact method of operation, which allows scanning at a distance, in hard-to-reach places.

After the changes are made, the information is transmitted online to a computer, where the software compares the received data and the specified parameters and demonstrates deviations: size mismatches, cracks, signs of deformation and corrosion, and other changes.

Applications


Source: sastrarobotics.com

Digital measurement is a high-tech process that has a number of important advantages over other verification methods. The only disadvantage of the technology is the high price of the equipment. In large industries, with a quick payback, the use of 3D scanners is economically justified. Consider examples:

  • large-scale production of parts and devices with mandatory input and output quality inspections;
  • small-scale production of objects of complex geometry, impossible without constant quality control.

Situations when other technologies cannot be applied:

  • work with objects made of specific materials deformed during the contact method for determining parameters;
  • measurement of electronic parts at risk of being damaged by static electricity;
  • re-measurements of objects that are not physically present can also be made on a pre-made digital copy.

Purposes of use


Source: www.capture3d.com Input control of materials and details is necessary at any enterprise. For large-scale production, selective batches are inspected. However, this requires a large number of controllers, which increases the cost of the product.

The use of 3D scanners automates the workflow, eliminates errors associated with the “human factor”, allows you to switch from selective quality control to continuous, increases the speed of verification several times compared to manual labor.

Analysis of the location of parts relative to each other

In a product consisting of several parts, it is important to monitor the correct arrangement of elements in relation to each other. Scanning technology easily captures the position of objects in space and transmits information to a computer monitor.

Checking the geometry of large objects

A number of large objects, such as construction equipment, marine and air transport, require regular testing of the hull geometry. The process is lengthy and requires the search for specialists with the necessary qualifications and experience. Metrological 3D scanners easily cope with the digitization of large-sized objects, guarantee high measurement accuracy and save time and financial resources of companies.

Checking the geometry of small objects

Sometimes measuring small objects is more difficult than measuring large ones. 3D scanners successfully measure to within a few microns, regardless of the size of the parts. Deviations of shape and size from the base model are highlighted in the program, which makes it easy to notice and eliminate them.

Selection of equipment


Source: tool-maker.net

There are dozens of models of metrological scanners on the modern digital equipment market. The choice of instrument begins with the identification of the range of tasks set by the production. Here are some parameters that you need to pay attention to and compare with key goals:

1. Working area

It is quite clear that large objects require devices with a large working area. Please note that the size of the working area is in inverse proportion to the resolution. By choosing a device with an excessive scan area, the user may find insufficient accuracy and resolution.

2. Data Accuracy

It is obvious that in aircraft construction and the production of other critical parts, the highest possible accuracy is required.

In reverse engineering of consumer goods, products without complex mechanics, as well as when used in the creation of works of art, souvenirs, in the development of computer games, such accuracy will not be used, for these purposes it makes no sense to overpay for a scanner tens and hundreds of times.

3. Run speed

This parameter includes the calibration and direct scan time. For high-volume production, where 3D scanning is used for quality control, involving dozens of measurements per minute, high speed is an important characteristic. Production of small batches of products and reverse engineering are less demanding on the speed of the device.

4. Software

We recommend giving preference to scanners that work with proprietary highly specialized software. The software required for processing scans, if not included, may require significant additional financial investments.

5. Price

When choosing a 3D scanner, you must independently or with the help of a qualified specialist correlate the tasks of the user and the capabilities of the device. It makes no sense to overpay for unnecessary features. At the same time, it is important that the device has the necessary set of parameters that are guaranteed to give the desired result. It is important to predict the payback period of the equipment.

Examples of 3D scanners for metrological quality control

Let's start our acquaintance with the presentation of the Russian sample - RangeVision Pro. The device is officially approved as a measuring instrument by the Federal Agency for Technical Regulation and Metrology.

whose quality had to be checked. The usual incoming inspection system could not cope with a large flow of products and did not have the ability to test objects of non-standard geometry.

RangeVision PRO 3D scanner was used to optimize the process. Current measurement technologies involve the transportation and storage of control samples in specially designated areas. The mobility of the Russian scanner made it possible to reduce logistics costs.

With the scanner, there was no need to move batches for measurements. RangeVision PRO works in workshops and warehouses - in any convenient place.

In this case, a three-dimensional model of a part with a size of 1700 mm * 720 mm was created. Stickers were pasted onto the part, which made it possible to automatically assemble individual images into a single 3D model. The information was processed by the proprietary ScanCenter software supplied with the scanner.

Quality Inspection at INKAY TECHNOLOGY

INKAY TECHNOLOGY SRL in Italy had the task of verifying that the dimensions of the body casting matched the base model saved in the CAD file. Given the non-standard geometry of the object, it was decided to abandon the usual technologies and use the RangeVision 3D scanner.

The work was done in 3 stages:

  1. We created scans of the outer part of the body using markers for automatic image stitching.
  2. To scan the inside, the case was divided into 2 parts, each of which was digitized separately.
  3. Stitched all the images into a single model.

As we mentioned above, 3D scanning is justified not only in high-volume production. Often the equipment is effectively used in the piece production of parts. The shipbuilding industry uses cast components with complex geometry, the quality control of which is difficult and time consuming. Therefore, the use of 3D equipment in the industry is becoming more common.

Krasnoye Sormovo specialists chose RangeVision to inspect the quality of the controllable pitch propeller hub.

Part height - 70 cm, diameter - 80 cm. The RangeVision PRO 3D scanner was moved around the hub, taking pictures from different angles. A 3D model was assembled from the 100 images obtained. The stl-file was combined with the basic calculation model in the GOM Inspect software to determine deviations. The work, as a result of which the specialists received an accurate report of the conformity of the finished product to the base model, took several hours.
