Manufacture of a medium-sized demonstrator of the aerospace industry based on WAAM, identifying the key aspects to be considered in the manufacture of this type of parts.
One of the project lines of TKNIKA's area of specialization in Additive Metal Manufacturing is related to the WAAM (''Wire and Arc Additive Manufacturing'') technology. This process is classified into the Directed Energy Deposition (DED) family process and as his description says is based on the deposition of a wire melted under the action of an electric arc . The main objective is the generation of knowledge through practice and experimentation in a network between different VET teachers and schools.
A medium-sized part has been selected, with a simple geometry, which would normally be manufactured from a metal block or a forged preform. In this case, an arc-wire manufacturing process can be a very interesting alternative. The main objective of this practice is to produce a quality preform, identifying the key aspects that allow it to be manufactured, in a controlled manner, on the Addilan WAAM V0.1 manufacturing machine.
The solution has been consisted on manufacturing three-piece series based on previous experiences.
