Composite-Polymer (FDM) 3D printing involves the process of extruding hot thermopolymer – composite material from a nozzle and layering it on top of one another, creating a 3-dimensional object. This process is commonly used for rapid prototyping but can also be used for short-run productions or to develop molds for long-run production, reducing the cost of tooling by avoiding traditional means of tooling production with a CNC mill or lathe. Most commonly used composite polymer materials such as Carbon fiber ABS, Carbon Fiber Nylon, Fiber Glass ABS, Kevlar ABS.
