Being able to successfully 3D scan objects for 3D printing is definitely getting better as time progresses. This article will look at some of the best 3D scanner apps for 3D printing so you can get some great results.

Best 3D Scanner Apps for 3D Printing

3D printing has faced a boom in the market as more and more people are getting interested in this helpful technology. Although most people design their 3D prints in CAD software, some want to print existing objects that they don’t have the skill to design, or are difficult to do so.

For such an object, 3D scanning apps have been developed that can help you in analyzing the object and then transforming it into a digital one in the form of a 3D scan. You can then import them into a CAD software for editing or directly print them via a 3D printer.

Below are some of the best and most helpful 3D scanner apps for 3D printing:

  1. Scandy Pro
  2. Qlone
  3. Polycam
  4. Trnio

1. Scandy Pro

Scandy Pro first came into the market in 2014. It is solely designed to work on iOS devices mainly including the iPhone series above 11 and iPad series above 2018. It is also runnable on the iPhone X, XR, XS MAX, and XS versions.

It is a free (with in-app purchases) 3D scanning app that can make your iPhone capable of becoming a full-fledged high-resolution color scanner. It supports a wide range of file types such as PLY, OBJ, STL, USDZ, and GLB.

Scandy Pro prevents time wastage as you don’t end up getting wrong or undesired scans and all this is ensured because the app has a feature to preview the object on the screen while it is being scanned.

The app works on LiDAR (Light Detection and Ranging) technology in which a sensor emits light and calculates the exact accurate distance between two spots. Make sure you place the iPhone or iPad at a flat or stationary place so that it doesn’t get disturbed while scanning.

Also, professionals recommend rotating and changing the position of the object instead of the camera for better and more accurate scanning.

As soon as you get the object scanned, you can either export it directly in any of the above-mentioned file formats preferably STL or you can do this process after utilizing various editing tools embedded in the application.

Check out the video below for a visual example of scanning through the Scandy Pro 3D Scanner.
