FDM is an additive manufacturing process that uses production grade thermoplastic materials. FDM works by laying material layer by layer to build a model. Building your part layer by layer, FDM can produce both prototypes and end-use parts.
Raw thermoplastic is used, eliminating mixing materials, supplied to an extrusion nozzle that is heated to melt the material. The nozzle can be moved in both horizontal and vertical directions by a numerically controlled mechanism, directly controlled by a computer-aided manufacturing (CAM) software package.
As the material is deposited it is immediately cooled and fused to the layer beneath it. This is repeated until the whole model is built, producing a prototype that is both highly durable, functional, and with great strength to weight ratios.
