Computer-aided design (CAD) software is essential for 3D printing, as it allows users to create and edit 3D models of the objects they want to print. There are many different CAD programs available, but not all of them are suitable for 3D printing. Some programs are designed for specific industries, such as architecture or engineering, while others are more general-purpose.
For 3D printing, it is important to choose a CAD program that is capable of creating high-quality 3D models that are suitable for printing. The program should also be easy to use and affordable.
