Technology
Investing in WAAM is also a good option for end users who own the Intellectual Property Rights to specific items of equipment . “ Traditionally , the end users would rely on getting products from the original manufacturer . Our technology means they can flip that around , engaging a more local manufacturer or perhaps even manufacturing themselves . Being more independent means you can shorten lead times and drive down costs . We have seen this step-change in the US Navy and Army ; they have a think tank charged with creating ideas to reduce dependency on their suppliers , preventing delays and ensuring that parts can be remanufactured .”
Standards
An often-raised question when discussing WAAM is whether sufficient standards are available . This is a topic Mr Van der Velden is keen to address . “ There are already general standards such as API- 20S ( Additively Manufactured Metallic Components for Use in the Petroleum and Natural Gas Industries ) and DNV-BT-203 ( Addition Manufacturing of Metallic Parts ) that allow end users to utilise metal AM in their production . There is also a more specific standard ASME Section IX ( a segment of the ASME Boiler & Pressure Vessel Code that comprises regulations governing the qualification of welding procedures and welders ), that allows 3D printing in our special way . Our method is Wire Arc Direct Energy Deposition ( DED ) and that has been covered for 18 months now . It ’ s a good sign that our process is standardisable ; it also shows that there is a lot more coming .”
Every year , MX3D creates unique WAAM items that help to push back technological boundaries . This 3D printed stainless steel bridge has been installed across one of Amsterdam ’ s most famous canals
Mr Van der Velden continues : “ What we are doing is welding , which has been standardised for decades . We therefore started out by reviewing standards for welded parts . 3D printing is really nothing more than stacking welds on top of each other . Hence the original standards have been readily adapted to allow the 3D printing of entire objects .
Of course , extensive testing has been performed which demonstrates that the pressure retaining capability of these items is excellent . The material properties are also at a high level and often superior to those of cast items . We have therefore already hit all the benchmarks , delivering consistent material and reliable properties .”
Unique piping components and pump parts like these can be quickly produced , even in exotic alloys .
