3D printing is becoming ever more popular in both the manufacturing world as well as in technology and engineering education classrooms all over the United States. 3D printing is an additive manufacturing process in which successive layers of material are built up to produce three-dimensional objects from computer-aided design (CAD) files, making complex parts and objects easy to produce. This is one rapid prototyping technology that allows companies to develop, test, and bring to market new product ideas more quickly than traditional methods for making new product prototypes. Additionally, 3D printing is used for small production runs of replacement parts. Students in technology and engineering programs benefit from using 3D printing technology in a number of ways. The authors of this article present what students and teachers can learn and achieve by producing their own filament for 3D printing applications.
