  • Fused Deposition Modeling, or FDM, is a layer additive manufacturing process that uses production-grade

  • thermoplastic materials to produce both prototype and end-use parts.

  • This technology is known to accurately produce feature details and has an excellent strength-to-weight

  • ratio. FDM is ideal for concept models, functional

  • prototypes, manufacturing aids and low-volume end-use parts.

  • The FDM process begins by "slicing" 3D CAD data into layers.

  • The data is then transferred to a machine which constructs the part layer by layer upon

  • a build platform. Thin thread-like spools of thermoplastic and

  • support material are used to create each cross-section of the part.

  • Similar to a hot melt glue gun, uncoiled material is slowly extruded through dual heated nozzles.

  • The extrusion nozzles precisely lay down both support and thermoplastic material upon the

  • preceding layers. The extrusion nozzle continues to move in

  • a horizontal X-Y plane and while the build platform moves down, building the part layer

  • by layer. The finished part is removed from the build

  • platform and cleaned of its support material. Raw FDM parts have visible layer lines.

  • However, service providers such as Solid Concepts offer multiple finishing options to create

  • smooth, even surfaced parts including hand sanding, assembly and cosmetic paint.

  • Since FDM parts are constructed with production-grade thermoplastics including ABS, Polycarbonate

  • and Ultem, they are both functional and durable. FDM is utilized in a number of industries

  • including aerospace, automotive, industrial, commercial and medical.
