How To Scan a 3D Object Accurately – 2024 Guide!

Scanning a 3D object is only possible with the help of a 3D scanner. Through this process, an environment or an object is being analysed. Moreover, it helps tell more about that particular environment or object. It tells a user more about the appearance of the object and helps collect all required information.

A scanning tool is used for the process, and it creates a digital object for accuracy and desired results. The same object that was scanned can now be replicated using a 3D printer. The best part of using such tools is that you can easily 3D scan objects yourself and get the best results on a budget.

For it to happen, you will need the right techniques. Keep reading to know more about scanning a 3D object. A process known as photogrammetry helps people obtain the best results while 3D scanning. Your search for the best 3D scanner ends with

In this process, you can capture the image of an object using a normal camera or a phone, and then upload it to reconstruction software. The software will help you obtain the desired results and maximum benefits. The software will help clean all imperfections captured using another app. When the desired picture is obtained, you can take a 3D printout.

Things You Will Need For Accurate 3D Scan Results


People who have tried 3D scanning earlier to obtain the desired results either used the camera of their smartphones or a scanner app. Having said that, you will not have to invest money in buying a bunch of equipment, nor an apparatus for scanning an object. A mobile device with a decent camera will do the job. Also, make sure that you use the correct software for editing purposes.

With plenty of scanners available in the market, the choice of picking the best one becomes difficult. Some scanners are available to capture small objects perfectly well. Whereas, other options are perfect for scanning larger objects, the head and the body.

Hence, keep your specifications and requirements in mind to make a better choice. The 3D scanners capture the object perfectly, and its complete shape with the help of a series of multiple points. These points are connected to render the image properly. This further helps serve the purpose.

The data points when combined result in the formation of a 3D object. This object then can be used to create another piece. The scanners employ certain technology to fetch the desired outcome. Some of the technologies are;

This way we can conclude that several different measurements are taken to encompass the exact measurement. Furthermore, such scanners also help in noting the minute details of an object for accuracy. The different data points and details collected are then combined into one data map. After this, the user can flesh out a scan for the best results.

Fundamental Scanning Process


You can scan an object in two ways, by using a basic scanner or using a complex one. A basic scanner is a DIY and any user can use it, without prior experience. On the contrary, to use a complex scanner a professional is required and also it requires some knowledge and previous experience.

When we speak technologically, undoubtedly 3D scanning is a complex process. Let us have a look at a step by step explanation of the 3D scanning process to have a better idea.

  • A 3D scanner app is nowadays available for mobile devices as well. You can download it on your phone to serve your purpose. Additionally, you can also invest in a 3D scanner machine, if you are looking for better results. Such machines are generally purchased by people who need to scan objects multiple times a day, and then create their replicas using the image.
  • The scanners have structured laser lights that start hovering over the object to create a 3D image. The lights do so with the help of data points.
  • The software then comes into the picture. You will have to use software that will help combine all the data points that were collected while scanning the object.
  • The data points here play a critical role, and you need to make sure that you use the best software for exceptional results.
  • Such points help in detailing the object and give an in-depth structure. They help to create a realistic and accurate model within a program designed to do so.

Though before considering scanning a 3D object either by yourself or through someone else, there are a few things you should know.

i. Size and Type of The Object: As stated earlier, you should be aware of the size of the object you want to scan. Different scanners are available to scan objects of different sizes. Hence, you should pick a suitable one that would scan your object accurately.

ii. Resolution: You should concentrate on the resolution of the object and the scanner. This will help you ensure that the required values are aligned before you get started with it. The accuracy of the scanned object is directly proportional to the resolution. Having said that, if you use a scanner of high resolution, the accuracy will be great too.

iii. Accuracy: Considering the accuracy of a scanner is best before you get started with the actual scanning process. The maximum level of accuracy that a scanner can give to a user lies somewhere between 30-100 microns.

iv. Scanning Speed: The speed of your scanner will not be a problem for capturing static objects. The difficulty lies for all movable objects that will need a certain level of speed to capture the movements of the object. The speed can be adjusted through software settings and you can get things done with greater ease.

The Bottom Line

There are plenty of great options available in the market that help get great results. Such scanners can measure even the most complex objects with greater ease, and hence, help in making a replica. They help design printed parts that fit in the best possible way on all kinds of existing products.
