Abstract Scope |
Hybrid additive manufacturing concept (HAMC) represents production of parts by combining PBF (powder bed fusion) and LENS (laser energy net-shaping) processes. PBF process is used for production of subparts with a high structural complexity, while LENS is used for joining of PBF subparts and to build additional large semi complex structures on top of PBF subparts. HAMC method could enable production of parts where benefits of both technologies, increased complexity combined with a high build rate, can be used in one product. However, to see the properties of HAMC parts for production of high performance parts, demonstrators have to be build and tested. The work presents mechanical testing of parts produced by HAMC approach. The samples were tested with different methods to establish different correlation like porosity-mechanical properties. The results showed that building strategy and process related defects had huge impact on the mechanical properties of HAMC parts. |
