Pump manufacturers use many different designs incorporating highly engineered components. To get the best performance and increase the flexibility in design, Stainless steels, super alloys, titanium and other exotics are utilised. Some of these materials are very expensive and traditional subtractive manufacturing techniques require beginning the machining process with a much larger billet or cast the part and then machine it to the final size and surface finish required. 3D printing produces parts that are much closer to the net shape. This near net shape allows manufacturers to only lightly machine locating faces or seal and bearing journals.

3D printing benefits the pump manufacturers in a number of ways. At the very start of the process it allows the designers to take advantage of manufacturing the ideal shape for the strength, flexibility, rigidity and other desirable qualities such as corrosion resistance. Significantly, it also allows designers to reduce the mass of components as there is no need to print material that has no function, such as the cast housings. This is particularly useful for high cost materials like titanium or even 316 SS.
