5 Common Mistakes with 3D Scanning and How to Avoid Them


Share post:

3D scanning technology has progressed to the point where it’s used in a variety of ways. In particular, medical and manufacturing industries rely on this modern innovation.

Yet, despite its prevalence and usefulness, 3D scanning can lead to a variety of mistakes. Knowing what to expect can ensure your project goes off without a hitch.

With that in mind, today, we’ll be taking a look at a few of the most common mistakes with 3D scanning. Let’s dive in!

1. Over-Scanning

It occurs when the scanner captures more points of the object being scanned than needed, causing extra detail and complexity to the 3D model. This can happen if the scanning user incorrectly sets the scanning parameters or is not mindful of the scan area size.

Over-scanning can be easily avoided by ensuring 3D scanner settings like scan parameters are configured correctly, and the scanning surface is managed so that the scanner does not capture any excess data points. 

2. Too Little Data

This can have consequences for the accuracy of the 3D model and the accuracy of the product being digitalized. Too little data can lead to a lack of information and incomplete results in 3D digitalization.

Taking a scan at too low a resolution and not enough pictures or scans from the scan region can lead to holes, gaps, and missing areas in the digital model. Moreover, using the wrong scan resolution in relation to the size of the object being digitalized can also lead to an incomplete digital model by not properly capturing all the details of the object. 

3. Wrong Scanner for the Project

Mistakes with 3D scanning and wrong scanners for the project can have serious implications for a successful outcome. Choosing the wrong scanner for the job will cause various time-consuming issues and potentially ruin the project due to an inability to capture the right data.

Many types of 3D scanners are on the market, each with unique features and applications. One example is an intraoral 3D scanner. It may not be easy to assess your exact needs without consulting a professional. Assessing the object size, shape, material, and other factors will help you decide which scanner is best for the project.

4. Poor Quality Lighting

The most common mistake seen with 3D scanning is poor-quality lighting. Low-quality lighting can lead to lost detail in scans or flat, low-contrast images. Poor lighting can also lead to surface gradients and dark spots that introduce visible artifacts into the scan.

To avoid this mistake, you must pay attention to the lighting in your setup and make sure it is not overly dark or overly bright. Soft lighting should be used with multiple sources coming from different angles. 

5. Incorrect Data Capture

Data capture involves capturing data and images that are incorrect or incomplete, which happens when a 3D scanning system doesn’t capture all the details of the scanned object.

This can happen when the system is not calibrated properly, when the lighting is poor, or when certain areas of the object are not adequately scanned. When this happens, the data capture is either incomplete or incorrect, which can lead to errors in the 3D scan results.
