17 Best Open-Source free 3D Printing Software of 2021
3D printing is also known as additive manufacturing which is the process of manufacturing three-dimensional shapes by adding layers of material on top of each other with the machine. It turns the computer model into a real model.
When this technology appeared for the first time, it was used to make prototypes for inspection before production, but over time it developed as a tool for the manufacture of complex products and became used for design.
The machines that are used to make 3D models need a program with extraordinary features and integration with computers that have spread widely in recent times due to the possibility of building designs through them.
