Have you ever wondered why your 3D scanner won’t capture the surface of certain objects? Or have you become frustrated by getting an incomplete 3D scan and scratching your head trying to figure out what you did wrong?  Various 3D scanning technologies exist, i.e. structured light, laser, photogrammetry, yet all have challenges due to limitation of physics.

Below objects are usually challenging to 3D scan.

1. Highly detailed objects
2. Dark surfaces
3. Reflective or shiny surfaces
4. Bright, colorful patterns
5. Humans

Fortunately, the key is to find the right 3D scanner for your objective and deploy some workarounds. Read on to find out which scanner would be best to overcome these challenges!

1. Highly-detailed objects

When capturing highly detailed objects, it is essential to ensure that the 3D scanning parameters are adjusted to capture sharp edges and intricate details accurately. The default scan parameters may not always capture these elements with sufficient detail. However, by customizing the settings, you can obtain an accurate 3D model that faithfully represents the object without losing any important details. One crucial setting to adjust is the point distance, which determines the resolution of the scan. By selecting a smaller point distance, you can achieve a higher resolution and capture finer details.
​
The EinScan Pro Series (EinScan Pro HD or EinScan Pro 2X 2020)  multifunctional 3D scanner is an excellent choice for scanning detailed objects, offering an adjustable resolution of up to 0.2mm. With this scanner, you can accurately reproduce intricate details, ensuring a high level of precision in your 3D models. Furthermore, the EinScan Pro Series provides efficient 3D scanning capabilities and a user-friendly experience, making it an ideal solution for capturing highly detailed objects with ease.

If you require a 3D scanner capable of capturing intricate details, a desktop 3D scanner would be a suitable choice. Among the recommended options are the EinScan SE, EinScan SP, Transcan C, EinScan Pro Series set up on a tripod. The Transcan C, in particular, offers an impressive resolution of up to 0.035mm, ensuring excellent detail reproduction.

It's important to note that higher resolution scans result in denser point clouds, which means more data and larger file sizes. Additionally, the software will take longer to process a greater amount of data. Therefore, it is generally recommended to use fine resolution settings for small or medium-sized objects. Scanning larger objects with a desktop 3D scanner or tripod setup can be time-consuming and labor-intensive as well. Before choosing a scanning method, consider the size of your objects. Finding the right balance between scan quality and efficiency is crucial. Assess the trade-off between the level of detail required and the time and resources available for scanning larger objects. By carefully considering these factors, you can select the most appropriate scanning method for your specific needs.

2. Dark surfaces

If you've encountered difficulties in 3D scanning dark objects, you're not alone. Dark surfaces pose a common challenge in the 3D scanning process due to their high light absorption. Just like wearing a dark-colored shirt under the sun, dark objects absorb more light, which makes it difficult for 3D scanners to accurately capture their surface details.

To overcome this challenge, there are a few techniques you can employ. One approach is to attach adhesive markers or targets to the object. These markers act as reference points that assist the 3D scanner in tracking and aligning the scan data. Another option is to apply white powder to the dark surface, which helps enhance the reflection of light and improve scan results. However, these methods can be time-consuming, messy, and may not be suitable for delicate objects.

Fortunately, not all light sources are created equal, and certain 3D scanners offer better performance when scanning dark surfaces. A more powerful laser and the use of blue light can be effective in capturing dark objects. Blue light has a narrower wavelength compared to white or red light, allowing for better resolution and detail capture.
​
The EinScan HX is equipped with powerful laser lines and blue LED light in its fast mode. This combination of technologies enables efficient scanning of dark surfaces without the need for markers or white spray. In just minutes, the EinScan HX can produce high-quality scans, even for objects as challenging as a black lion sculpture.
​
By utilizing advanced 3D scanning technologies specifically designed for dark surfaces, you can achieve accurate and detailed scans without the additional steps of applying markers or powder.

3. Reflective or shiny surfaces

Shiny and reflective surfaces present another common challenge in 3D scanning. While dark surfaces absorb light, shiny surfaces, such as mirrors or shiny metal parts, disperse and reflect light in various directions, making it difficult for 3D scanners to accurately capture the object's details. Remember how 3D scanners work.  3D scanners project light onto objects, and measures how the light is returned or deformed, but reflections make it impossible to ready.
​
In industries like machinery or automotive, shiny and metallic parts are often scanned, necessitating specific techniques to overcome this challenge. Markers and the power of the light source play crucial roles in scanning shiny surfaces. A more powerful and high-quality light source significantly improves a 3D scanner's ability to capture data from shiny objects. In some cases, especially with medium and large-sized objects, markers may be necessary to ensure excellent scanning results. Using magnet markers can provide a quick, easy, and non-destructive removal solution as well.
​
The EinScan HX, equipped with a powerful blue laser light source and marker recognition capability, is designed to address this 3D scanning challenge. Among all the EinScan Series 3D scanners, it is the only one capable of effectively capturing shiny objects. Its advanced features enable successful scanning of metallic surfaces, as demonstrated in the example below.

4. Colorful object

When scanning brightly colored objects, it is crucial to ensure accurate representation of the object's color information in the generated data. This heavily relies on the pixel count or digital resolution of the texture camera used. Pixel count is typically measured in megapixels (MP), where one MP equals one thousand pixels. Insufficient camera resolution can result in color distortion and loss of detail.
The good news is that all EinScan 3D scanners have the capability to capture texture data. The EinScan H and HX models come equipped with built-in color cameras, while the Pro Series offers color capture functionality through an optional color pack add-on.
​
Different 3D scanner models offer varying camera resolutions to accommodate different budgets and specific use cases.

For those seeking the highest level of color detail, the Transcan C 3D scanner is the ideal choice. It features an exclusive 12-megapixel texture camera, offering superior color detail with its higher pixel count. With the Transcan C, you can expect to capture the finest color details and achieve excellent color accuracy in your 3D scans.

5.  Scanning humans

When it comes to 3D scanning the human body, there are three key challenges that need to be considered: (1) maintaining stillness, (2) avoiding direct light in the eyes, and (3) successfully capturing fine details such as hair.

Firstly, it is crucial for the subject to remain as still as possible during the scanning process. Even the slightest movement, such as blinking or shivering, can introduce inaccuracies in the final 3D model.

Secondly, some scanners utilize intense LED lights that can be uncomfortable or temporarily impair vision if directly exposed to the eyes. This can cause discomfort and hinder the scanning experience.

Lastly, capturing the intricate details of human hair presents a challenge due to its thin nature and the potential for it to blend together or appear less defined in the scan.

Fortunately, specialized 3D scanners have been developed to address these specific challenges. The EinScan H and Einstar are excellent examples. These scanners incorporate "non-rigid" algorithms in their software that automatically compensate for slight body movements, reducing the impact of any minor shifts during scanning.

Additionally, they utilize infrared rays instead of LED lights or lasers, eliminating any discomfort or vision impairment. Infrared technology proves effective at capturing both dark and light-colored hair, ensuring accurate representation of fine hair details in the resulting 3D scans.

When it comes to body 3D scanning, the EinScan H and Einstar, along with their dedicated software, serve as efficient and reliable allies, helping overcome the challenges associated with scanning the human body. As you can see below, EinScan H will give you much more detail than the Einstar.

Conclusion

Despite the challenges posed by certain surfaces, overcoming them is possible by employing the right combination of hardware and software solutions.

The EinScan series offers a wide range of 3D scanners designed to accommodate various situations and budgets. Each scanner within the EinScan lineup possesses unique features and specifications, making them suitable for different users and applications. Whether you're scanning complex surfaces, intricate details, or specific objects, there is an EinScan 3D scanner that fits your requirements.

​Every once in a while, it’s important to revisit the basics to understand how 3D scanners work. In this blog post, we’ll cover the Field of View (FOV) of a 3D scanner and how it affects the 3D scan results. The key takeaway is that different 3D scanners have different FOVs, and choosing the right model is crucial to getting the right output depending on the size of the object you want to 3D scan.

Like how humans can see a certain range (you can't see behind you) at a given moment, different 3D scanners have a different viewable area at one time from a specific distance. The larger the FOV, the larger area the 3D scanner can 'see' thus capture at once.  With the EinScan 3D scammer models, there is a variety of scanning range among different 3D scanner models that scan something as small as a coin to something as large as a car.  Therefore, it is important to understand what you are scanning and what FOV is most suitable to capture the details of the object.

The FOV of a 3D scanner can determine which model is best suited to 3D scan your object depending on its size. Choosing the right field of view is about finding the right balance between capturing enough detail of the object you want to scan and appropriate coverage for each scan. This balance is important so you can achieve a smoother scanning experience, complete scans in a shorter amount of time as well as reduce computer crashes that happen when the software is overloaded.

Some scanners have dual FOV like the Transcan C and the eviXscan 3D Quadro+ so it can scan small and medium size objects.  On the TranScan C, you can slide the cameras out to increase the FOV, while on eviScan Quadro there are 4 cameras installed - the inner cameras and the outer cameras.​

It really depends on the simplicity and versatility you require for the project.  Naturally, having multiple FOV is a bit more complex due to having varying settings.

Now let's dig a little deeper and look at the difference in FOV of Einscan Pro HD vs. Einscan Pro 2X 2020.

You can see that these 2 scanners have a different FOV.  Guess which one is better suited for large objects?  You probably guessed it right if you followed the logic so far - it's the EinScan Pro HD. Objects that are not very large like within the 3-100mm range, EinScan Pro 2X 2020 is better and it's cheaper too!  ​

So, keep in mind that there is no one-FOV-fits-all 3D scanner if you want a great 3D scanning output. The first step in choosing a 3D scanner is to confirm the size of the object you need to scan so it can help you determine the FOV of the scanner required. In the next blog, we will help you narrow it down further and together we will look at how the material on the surface of the object can affect your purchase choice.

With over 35 years of business experience and an extensive history working on Ferrari vehicles, Italian Design and Racing, based in Mesa, Arizona, is a custom fabrication and restoration company that specializes in Italian exotic cars. Their engineering team is using the EinScan HX Handheld 3D scanner to preserve a vintage racing car body which was placed on a more modern Ferrari chassis.

Chris Carpenter, lead technology engineer, talked about his experience with 3D technology and how the hybrid light source 3D scanner, EinScan HX completely changed their workflow.

After a crash destroyed the original Ferrari 750 Monza Spyder body, an aspiring young car builder, Peter Monteverdi (a Swiss car maker and creator of the car brand Montiverdi) designed the first gullwinged door body to be used on a Ferrari chassis, which at the time was built by Sauter out of Switzerland in 1957.

The gullwing body had been kept by private collectors off of its original chassis.

“We’re looking to restore the car body”,  says Carpenter. “We’ve adapted a more modern Ferrari chassis and drive train to restore its bespoke look.”  Carpenter joining the team has shifted its restoration process from analog to digital, with EinScan HX Handheld 3D scanner being a key tool to digitize the parts for restoration projects.

Cutting A Fender Using Geomagic Essentials

Edward’s goal was to cut a fender and make sure it was the right size for installation. Usually, he will print out the part for test, and in this case he offers an easy-to-print and material-saving trick.

​He creates a small offset about 5 mm or even less, and cuts the part again, so that he gets a tiny piece of the fender, but maintains the geometry he need. 3D printing this thin piece was just as good for installation testing, and using only a minimal amount of printed material.

Reverse Engineering An Engine Using Geomagic Essentials And Fusion 360

Furthermore, Edward uses Geomagic Essentials to extract features on the engine, and then using Fusion 360 to model the three holes in which he wants to simulate the mounting bolts.

This is basically how to go from scanning to printing of a part; how to use a mesh and model mounting bolts in Geomagic Essentials and Fusion 360. And it is clear how much can be done with a bundle of 3D scanners and softwares.

Are you still using calipers? Have you tried reverse engineering using 3D scanners? It's a new tool for an old task.

Merriam-Webster defines reverse engineering as "the process of disassembling and examining a product or device to discover the concepts involved in its manufacture, usually with the goal of producing something similar."

As the design process is beoming digitized, reverse engineering today is more commonly associated with the process of converting a physical object’s geometry into a digital 3D model and replicating the original design or further improving for new manufacturing processes such as additive manufacturing. More engineers are moving away from using calipers and adopting 3D scanners to take measurements, especially of complex parts.

3D scanners allows you to digitally capture the geometry of even the most complex parts in an extraordinarily quick and precise manner. A large docking pump was recently captured in just 20 minutes for example, with the help of laser 3D scanning. This technology has enabled the use of reverse engineering in situations beyond simple benchmarking and part reproduction, as we explore in the next section.

Main Applications for 3D Scanning & Reverse Engineering

Reverse engineering with 3D scanning offers many possibilities for product development and manufacturing. Overall, the different uses of reverse engineering can be divided into three major applications: (1) to replicate parts,  (2) to create variations of existing parts, or (3) to develop entirely new parts based on an existing environment or object. Let's look at each application in a bit more detail.

1. Recreate & Replicate Parts

One of the most popular uses for 3D scanners is recreating damaged or worn-out parts that are unavailable from the original supplier or lack proper documentation. This is a common problem when working with old machinery or vintage vehicles, and it’s always challenging to do with manual reverse engineering tools like calipers. However, with a good 3D scanner and the proper software, it can become a straightforward task.

Katsuya Tanabiki, for example, shared his process of reverse engineering a shield notch on an old motorcycle helmet. The helmet featured two shield notches, but one was broken, and it was too difficult to obtain a replacement notch. This tiny part was 3D scanned with an EinScan Pro 2X in Fixed Mode, and later 3D printed.

2.  Improve The Design of Existing Parts
​
Another goal of reverse engineering is to use digitized parts to create new and improved variants instead of merely reproducing them. This method can significantly reduce the time and costs of creating parts from scratch and also ensures a perfect fit for components belonging to larger assemblies.

Taiwanese company Kiden Design has illustrated the reverse engineering process of optimizing a pipe using 3D scanning, CAD, and 3D printing. The EinScan Pro HD 3D scanner, used in Handheld mode, captured the irregular geometry of the pipe on two opposite sides that were stitched together later in software.  Thanks to the accurate 3D model obtained, the geometry could be easily optimized in CAD.

​This particular technique is also commonly practiced by medical professionals since body parts are unique and challenging to accurately replicate using manual methods. Here, 3D scanning once again has proven to be an efficient tool for digitizing human parts and surfaces.

Earmolds, for example, are patient-specific parts that help conduct sound from the hearing aids to the ear canal. Servicing or creating new earmolds from scratch can take several weeks during which patients experience hearing problems without them. However, thanks to reverse engineering methods with 3D scanning and 3D printing, the Hearing Beyond Audiology Clinic in Toronto can produce temporary earmolds in just one day. The temporary accessory allows patients to keep their hearing while waiting for the earmolds to be produced or serviced in other facilities.  Similar reverse engineering methods with 3D scanning are also utilized for producing facial prosthetics and custom orthotics.

Quality Data Capture Is Key for Successful Reverse Engineeing

​The use cases above clearly demonstrate the central role of 3D scanning in reverse engineering. It comes as no surprise that the effectiveness and accuracy of data captured by 3D scanning are crucial for a successful reverse engineering process. Yet, the software tools used for processing the data and working with the 3D models are also essential for achieving the desired results in reverse engineering. To understand the importance of good data and adequate software, let’s go over the main steps of reverse engineering with 3D scanning.

Step 1. Data acquisition

The very first step in any reverse engineering process is data acquisition. Regardless of the method, proper planning and preparation can make the difference between good and poor data. With 3D scanning, this involves selecting the correct device for the job, including the proper configuration (handheld or stationary) and accessories such as turntables, fixtures, and calibration panels. Correct calibration of the device is also vital to acquire quality data.

The regions or parts to be digitized usually demand some kind of preparation. Besides a good cleaning, some 3D scanning devices also require the use of markers or even special coatings on reflective surfaces. One should also consider the ambient conditions before starting the digitization process. A controlled environment (e.g. indoors, without direct sunlight, a cleared tabletop, …) is always preferred to reduce noise in the data, but that’s not always possible. All the factors mentioned will contribute to proper data collection, which will in turn determine how quickly and easily the data can be processed next.

Step 2.  Post-Processing

The next step in a reverse engineering process is post-processing the acquired data, or the  “point cloud”. Here, the point cloud is processed by software tools – like EinScan software – resulting in a 3D mesh representation of the digitized object.

​The better the data quality acquired, the less post-processing and repairing will be needed. The post-processing step is also when reference entities are assigned to the 3D model, a procedure that should expedite the next stage of the reverse engineering process.

Step 3. CAD Model Generation

The final step in a reverse engineering process is to convert the mesh representation of the physical object captured by the 3D scanner into a solid 3D model.

IR Mode Data Quality Improvment
​
IR Mode (Infrared Ray Mode) uses an invisible light source thus suited for scanning people and slightly reflective objects. Data quality and accuracy are lower that in white light mode but with the new update of V1.1.0.1, captured data quality has significantly improved in IR mode.

Look more closely and you'll see massive improvement.

Data Quality Indicator Function

The updated HV1.1.0.1 has a new data quality indicator tool to help you get better data. The red color represents the insufficient data amount, the yellow color represents the imcomplete data amount, and the green color represents the adequate data amount so easy to see if you have captured sufficent data while you are scanning.  This is implemented in the Einstar too.

​Mesh Select Tool：Select Through / Visible
​
A new functional selection tool has been added to the post processing session. You can now select either a through or a visible point cloud.

Shining 3D has come out with an affordable 3D scanner to enable 3D scanners to be used by more people to digitize our world in full color!  Best suited for VR/AR applications and digital content designers for sure.

​It's pretty good for a low cost 3D scanner, but ofcourse if you want more accuracy you do need to step up a notch for the higher end models.

Check out the video we created below.

Also beware you do require a good GPU and lots of memory to run this 3D scanner. 

In 3D scanning, accuracy is a key metric in choosing which model to use for your project. 

How accurately do you need to replicate the physical model? In other words, how authentic do you want the 3D digital model of the real object to be?

High end 3D scanners like eviXscan Quadro+ can achieve up to 0.007mm (7 microns) accuracy, while lower end 3D scanners like EinScan SP can still achieve an accuracy up to 0.05mm (50 microns). Accuracy of a 3D scanner depends on the quality of the camera, projector lights as well as the software.

Meanwhile there is another important metric, resolution.  Resolution is about defining the point distance the 3D scanner can capture to generate the point cloud which is then converted into a mesh.  If you 3D scan your object in high resolution, the point distance is small thus details will be more visible, while if you 3D scan your object in low resolution,  the point distance is bigger.

Below is a guideline of resolution settings that is optimal depending on the type of objects you are 3D scanning. Basically the recommendation is the smaller the object, use high detail (higher resolution) and the larger the object, use low detail (lower resolution) settting.

The Einscan Pro HD and EinScan 2X 2020 provde super high resolution with HD scan mode and setting the resolution to "High Detail".  This kind of high detail captures is useful for objects with that has a lot of details like the object below.  On the other hand, large engineering parts may not require such detail but higher accuracy.

Basically the tip is to think about what you are going to do about your 3D scan file and choose the right resolution setting depending on the object you are 3D scanning.

Alignment is an important step for 3D scanning to ensure the 360 degree digital surface model generated by the 3D scanner accuractly replicates the physical object.

With Shining 3D scanners, there are several alignment methods that can be deployed, depending on the shape of the target object.  Let's go through them one by one.

Also important to remember is when you are 3D scanning a large object on a tripod without a turntable, you need to ensure there is at least a 30% overlap from one scan to the next to ensure alignment.

​So that's it.  Not as difficult as you thought, right?
