Key insights

💡

High-end 3D scanners, such as the Rexcan CS+, use a turntable and cameras to capture the form of an object, while others like the Artec Eva require manual movement around the object to create a 3D model.
🔄

The use of turntables and multiple cameras/lasers in 3D scanning allows for capturing shape, color, and depth data from objects, providing a more comprehensive representation of the scanned subject.
💡

To create a good 3D scan, it is important to completely rotate around the object and shoot at least 20 photographs of it to maximize the chance of success.
🔄

The process of 3D scanning requires selecting and uploading a series of photos, highlighting the importance of image selection and organization.
🖱️

The ability to zoom in, rotate, and manipulate the 3D scan data enhances the user experience and enables a more thorough examination of the captured object.
💻

Meshmixer is available for both Windows PC and Mac, making it accessible to a wide range of users interested in 3D scanning and object manipulation.
🖨️

"I've scaled it to 75 millimeters tall before exporting g-code for the object to an SD card that can be inserted into a patiently waiting." - The use of g-code and SD cards in 3D printing allows for precise control and easy transfer of models.
🐘

3D printing allows for the creation of intricate and detailed objects, as demonstrated by the printing of an elephant in different sizes.
