Do you need photography for 3d printing?

Need to master some software such as ps to facilitate modeling. 1. Download the model directly. Now there are many websites with 3D models on the Internet, with a great variety and quantity, which can be downloaded to various 3D models and basically printed directly in 3D. 2. Reverse engineering modeling based on 3d scanner. 3d scanner's reverse engineering modeling is to scan the physical object with a scanner, get three-dimensional data, and then process and repair it. It can accurately describe a series of coordinate data of the three-dimensional structure of an object, input it into 3D software, and completely restore the 3D model of the object. 3. Modeling with modeling software. At present, there are many 3D modeling software on the market, such as 3D and CAD, which can be used for 3D modeling. Other 3D printer manufacturers also provide 3D modeling software.
