How to Choose the Best 3D Scanner to Use With Your 3D Printer

3D scanning has an important place at the beginning and end of 3D fabrication workflows. Engineers, product designers, and researchers use 3D scanners as a faster and more efficient way to start constructing digital models, whether by incorporating existing designs via reverse engineering, digitizing hand-sculpted clay designs, or referencing the exact shape of the human body.

After fabrication, 3D scanning can support quality control and help to verify the accuracy of a 3D printed part, or, after the part has been used, a scanner can reveal how it’s performed—a scan of a deformed part can show you where to reinforce the design in the next revision.

With such a wide range of product options from handheld 3D scanners to desktop 3D scanners, it can be difficult to choose the best 3D scanning system that’s right for your application and budget. In this post, we explore the most important factors to consider when purchasing a 3D scanner and showcase some of the key applications that are empowered by combining 3D scanning and 3D printing.

There are multiple scanning technologies currently on the market, all offering their own advantages and weaknesses.

Laser triangulation uses light projected onto the object to take up to millions of measurements (dots) per second. The light reflected from the dots back into the scanner’s sensor to help it capture the geometry of the object. These types of scanners are often the most accurate, and are great for highly detailed parts that have opaque surfaces.

Laser triangulation scanners do have limitations. For example, this technology is not used in most portable scanners because the laser dots need to project from a stable source, and the source has to be kept a close distance from the scanned object. Laser triangulation scanners don’t always work on transparent or shiny surfaces either. Typically, they require reflective markers to be applied onto the object, which need to be removed after use and can be an obstacle depending on the object being scanned.

Finally, the laser dots can be harmful to human eyes, so it is important to use extra safety precautions when scanning body parts with a laser triangulation system, or to check with your scanner manufacturer to make sure the device is eye-safe.

Structured light scanners (also known as white light scanners or blue light scanners) generally use a projector with two cameras at angles on either side. A pattern of light is projected and laid over the component being scanned, the cameras capture the ways in which the object deforms the light pattern, and then multiple images are integrated into a single 3D snapshot.

Structured light scanners are available in both stationary and portable format—the technology is the most commonly used process for handheld 3D scanners. Structured light scanners are far more common in medical applications, since it is safe to use on both humans and animals and excels when an object is not perfectly still. Traditional white light scanners have been slower to scan than laser triangulation scanners.

Structured light scanning is the most commonly used technology in handheld 3D scanners.

Depth-sensing cameras project a field of dots in infrared (IR) to sample a 3D scene. Depth-sensing cameras are simple to use and are the least expensive scanning option, but their accuracy and resolution are low, and fine details are sometimes lost. Large objects may be captured with depth-sensing cameras, but accuracy declines with increased distance from the subject and at steeper angles to the camera.

Photogrammetry means the act of deriving precise measurements from photographs. It involves taking a set of overlapping photos of an object, building, person, or environment, and converting them into a 3D model using a number of computer algorithms. This is the most commonly used method when creating a 3D scan with a smartphone, since modern phone cameras are capable of capturing and combining a large numbers of photos. Photogrammetry should be considered the least expensive and least accurate method for creating 3D prints, and is not suitable for serious business applications.

LiDAR (light detection and ranging) sensors can be found on some higher-end smartphones and tablets, such as the latest versions of the iPhone Pro and the iPad Pro. This has made the iPhone and iPad viable scanners for those with only occasional scanning needs, offering performance a step above devices that only have access to photogrammetry. Applications that generate 3D mesh files via your smartphone’s or tablet's camera should be seen as the floor for entry-level scanning; users should expect additional work in their CAD software to remove gaps in meshes and improve the 3D model for applications like sending it to a 3D printer. Smartphones use fewer light points when scanning objects, resulting in less detail than a true, stand-alone scanner. iPhones are good substitutes for scanners if you have significant CAD design ability or need to transfer basic models into a digital space.

With accuracy in the range of 0. 1 mm or better, laser and structured light scanners are a good fit for professional applications and alongside high-resolution 3D printers. Formlabs stereolithography (SLA) 3D printers (such as the Form 3+) produce parts at a similar accuracy, and with a similar printable area, to the scan volume of many desktop 3D scanners.

Besides the accuracy between measured points and their actual location, scanners also vary in terms of resolution, which is the distance between captured points at a given scan distance. This means that details on the scanned object that are smaller than the scanner’s resolution won’t be captured. For example, a highly accurate 3D scanner with a lower resolution might detect the general shape of jewelry on a statue, but not clearly show individual details on a ring or necklace. Depending on your project requirements, this may or may not be a dealbreaker.

An easy way to remember these metrics is: accuracy is the measurement error between the part and digital value. Resolution refers to the density of measurements.

Accuracy can mean slightly different things depending on the manufacturer and 3D scanning technology. For example, the accuracy of handheld scanners depends on the distance to the subject and the quality of scan reconstruction, while desktop scanners have consistent accuracy within the constrained scan volume. If you are considering buying a 3D scanner for precise measurement, make sure to compare like to like.

In general, structured light scanning provides the best resolution and accuracy when compared to laser scanning. For some artistic use-cases for 3D scanning you may need a lot of detail, while overall accuracy is less important—especially if you don’t require your part to fit precisely with other parts in an assembly. In these cases, photogrammetry is an excellent low-cost option to explore.

Both depth-sensing cameras and photogrammetry are a good solution for scanning large objects in order to create 3D printed scale models and also offer enough accuracy for capturing the shape of the human body.

Several entry-level laser scanners are available using technology similar to higher-end systems. These scanners are a great way to start replicating small objects at 1:1 scale. As one would expect, the accuracy of entry-level laser 3D scanners is lower than a high-end scanner, but they can easily provide enough detail to replicate small decorative objects and figures where accuracy is not critical.

If you only have occasional 3D scanning needs, digitization services can scan your object, as well as perform CAD translation and accuracy inspection.

The area that a 3D scanner can capture varies significantly between scanners. Find a scanner that fits your size and resolution requirements without too much overhead, as cost typically increases with scan volume.

Handheld scanners can be manually moved around the object and have fewer size constraints than desktop models. Most inexpensive handheld scanners can capture objects from the size of a basketball to an entire room. High-end handheld scanners have an even wider range, and fill the niche for all objects that require precise measurements, but cannot fit in a desktop scanner. Handheld scanners are also able to capture objects nearly instantaneously, which makes them well-suited for taking human measurements (where the subject is not perfectly still) for ergonomics and medical applications.

If the area of the model can’t be seen by the scanner, it will cause a gap in the model. You can automatically repair small missing sections with most scan software programs to create a 3D printable model. However, repaired holes are rarely accurate to the original object. For parts that demand close to perfect accuracy, auto-repair of gaps or holes will not be sufficient. Read our MeshMixer tutorial for advanced tips to edit and repair 3D files for 3D printing.

Many scanners use turntables to increase what the scanner can see. The sophistication of a scanner’s turntable affects how easily and completely the object is captured: some scanners have the ability to move the object around multiple axes, imaging the object from more angles. This feature is important when reverse engineering plastic parts with deep recesses and ribs, which are impossible to capture from a single angle.

Scanners may rotate the object to capture occluded areas. Red regions are occluded and will be missing in the scan. Areas with deep relief are difficult for a single axis turntable to fully capture due to occlusion.

Cost concerns are straightforward; how much you are willing to spend on a scanner will reflect your business’s budget and how often the scanner is going to be used. Higher cost scanners will be able to capture small objects and create highly-detailed meshes that don’t require significant touch-ups in CAD software. Handheld scanners are also often on the higher end of the price range, due to their portable nature. The low-cost scanning market offers a wide range of options, but you have to know what to look for.

A 3D scanner expands the capabilities of a 3D printer, allowing you to replicate the shape of almost any object. Together, the two technologies create a powerful, digital workflow that can simplify and sophisticate processes in a range of industries.

The output from a 3D scanner is a mesh of triangles representing the surface of an object at a real-world scale. In some cases, the scan can be used directly to replicate objects without any CAD work. A hybrid workflow can also be powerful, where solid CAD models are combined with scanned 3D models. For example, customized ergonomics capture a physical imprint of a part of the human body, and integrate them with a mechanical design.

3D scanners are also valuable tools for measuring the accuracy of manufactured objects. Many factors affect 3D print accuracy, and metrology-grade 3D scanners provide a clear picture of how a material performs for demanding applications.

A variety of powerful workflows are enabled by combining a 3D printer and a 3D scanner:

  • Reverse engineering to create replacement parts, products with custom ergonomics, and more.
  • Replication and restoration of parts, especially in art and jewelry.
  • Consumer audio for creating custom earpieces.
  • Dental and medical applications, and how 3D scanning is enabling patient-specific workflows.
  • Metrology to validate and measure the accuracy of manufactured objects.

3D scanning is a technique used to capture the shape of an object with a 3D scanner. The result is a 3D object file that can be saved, edited, and even printed in 3D. Some 3D scanners can collect shape and color data at the same time. 3D scanning is compatible with computer-aided design (CAD) software, as well as 3D printing after a little training in the relevant programs.

3D scanning technologies:

  • Photogrammetry – 3D modeling from photographs. The principle of photogrammetry is to analyze several photographs of a static object taken from different viewpoints and automatically detect pixels corresponding to the same physical point. The input required from the user is camera parameters such as focal length and lens distortion. Photogrammetric technology is also capable of reconstructing objects of various scales photographed from the ground or from the air. The main advantages of 3D photogrammetry scanning technology are its accuracy and speed of data collection. nine0164
  • Structured Light 3D Scan - Structured Light 3D Scan technology works by projecting a series of linear patterns onto an object. The system is then able to examine the edges of each line in the pattern and calculate the distance from the scanner to the surface of the object. The structured light used for 3D scanning can be white or blue and is generated by numerous types of projectors such as digital light processing (DLP) technology. The projected pattern is usually a series of light rays, but can also be a random dot matrix. The main advantages of structured light technology for 3D scanning are speed, resolution and the ability to 3D scan people. nine0164
  • 3D Laser Triangulation Scanning Technology – Laser triangulation based 3D scanners use either a laser line or a single laser dot to scan an object. Using this method, digitization begins with the emission of a rectilinear laser beam, which deforms upon contact with the object. Using a camera, the 3D scanner analyzes the deformation of the line emitted by the laser on the reliefs of the object in order to determine its position in space using trigonometric calculations. The angle formed between the camera and the laser beam, the distance from the camera to the object, and the distance from the laser source to the object (known from the calculation of the time it takes the laser to go around) are parameters. which allow you to determine the spatial coordinates of the object. The advantages of laser triangulation technology for 3D scanning are resolution and accuracy. nine0164
  • Laser pulse based 3D scanning technology is a 3D scanning technology based on calculating the time it takes for a laser to reach the surface and return. Each measurement made by a 3D scanner reports a point on a surface, and the operation must be performed hundreds of thousands of times over the entire surface. This 3D scanning technology includes laser pulsed 3D scanners and phase shift 3D scanners. They, in addition to modulating the amplitude of the laser beam used for 3D scanning, also modulate its phase. These systems offer superior performance by combining the two types of modulation. Advantages of pulsed laser 3D scanners: the ability to scan large objects and the environment. nine0164
  • 3D Contact Scan uses contact between a probe and an object to reveal surface information measured by probe deformation. This is done using a touch probe, also called a probe or probe, connected to a 3D scanner.
