The most common plastics for additive manufacturing are PLA, ABS, HIPS, PHA, PEEK, PETG, PEI/ULTEM and polyamide. In addition, it is now also possible to print softer plastics such as TPE. The filaments are made by extruding plastic pellets. Additive manufacturing or 3D printing technology produces three-dimensional parts from computer-aided designs (CAD). In FDM, fusible plastic is built up layer by layer to form a workpiece. In newer technologies, it is possible to print more flexible plastics (thermoplastic elastomers), as well as to print continuously using a conveyor belt printer or to print in large format.
