3D modeling is the process of creating a computer generated object. These can be used in a number of applications such as 3D printing, movies, or scientific studies.
Printing is an additive process of producing objects using computer generated models. There are many types of 3D printers, including FDM and SLA, and an increasing amount of affordable printers and materials. Printing materials include traditional plastics like PLA and ABS, metal and metal composites, nylon, castable resins, food, biological material, and more.
Different fields use 3D printing for various reasons. Using this tool for personal, educational, and research use offers a relatively accessible and cheap way to produce customizable objects and work through research problems/questions. For example, 3D printing can be used for:
