What do you do if you need the best 3D scanning tools for your professional projects?

1 3D scanning methods

When it comes to 3D scanning, there are various methods available, each with its own benefits and drawbacks. Photogrammetry is a popular choice as it is relatively inexpensive and easy to use, however, it requires good lighting, a stable camera, and a lot of processing power. Structured light projects a pattern of light onto an object to measure the distortion caused by its shape, but can be sensitive to ambient light, reflections, and movement. Laser scanning is accurate but expensive, slow, and potentially harmful to the eyes. Contact scanning is precise but invasive, time-consuming, and limited by the size and shape of the probe.

2 3D scanning hardware

When choosing the hardware for 3D scanning, you need to consider your budget, needs, and preferences. Smartphones such as the iPhone X or Samsung Galaxy S10 may have built-in cameras or sensors that can perform 3D scanning, or you can use apps like 3D Scanner App or Scandy Pro to turn your phone into a scanner. Handheld devices like the Structure Sensor, Sense 2, or EinScan Pro 2X are portable and versatile, but may have limited battery life, range, and resolution. Desktop devices such as the Matter and Form V2, Einscan SE, or HP 3D Structured Light Scanner Pro S3 are more accurate and stable but may have a limited field of view, size, and speed. Professional devices like the Artec Eva, FARO Focus, or Creaform HandySCAN are very precise and fast but also very expensive and complex.

4 3D scanning tips

The fourth thing you need to know is that there are some tips and tricks that can help you improve your 3D scanning results and avoid common problems. To begin with, it's important to prepare the object for scanning by making sure it is clean, dry, and free of dust or dirt. Additionally, any stickers, labels, or logos should be removed and if the object is shiny, transparent, or dark, matte spray or powder should be used to reduce the glare or increase the contrast. Furthermore, when choosing an environment for scanning, it should be suitable for the method and hardware being used. Direct sunlight, shadows, or reflections should be avoided and a plain background or turntable can be used to isolate the object and facilitate alignment. Additionally, there should be enough space and stability to move around the object or place the scanner. Lastly, make sure to follow the instructions and guidelines of the software and hardware being used. Adjusting settings and parameters according to the object and desired outcome is essential. It's also important to check feedback and indicators that show the quality and coverage of the scan as well as review any errors or gaps that may occur during the scan.

5 3D scanning alternatives

The fifth thing to consider is that there are alternatives to 3D scanning that may suit your needs better or complement your workflow. Modeling is one option, where you can create a digital model from scratch using 3D modeling software. You can also download an existing model from online platforms or libraries, or outsource the 3D scanning to a professional or company. Modeling gives you more control and creativity, while downloading saves time and money. Outsourcing simplifies the process and ensures satisfaction, but it can increase costs and dependency.
