WP3 was in charge of all the manufacturing activities within AERIALIST. A broad spectrum of additive manufacturing (AM) technologies were utilized. The project has demonstrated that AM technology now allows the printing of structured acoustic absorbent materials at the appropriate microscopic scale and in useful sample volumes. This was a key objective of the project and a strong success; however a number of challenges remain before large scale industrialization of AM parts can be achieved. Within AERIALIST the following technologies were utilized extensively:
(i) stereolithography (SLA)
(ii) digital light processing / masked stereolithography (DLP/MSLA)
(iii) selective laser melting (SLM)
(iv) fused deposition modelling / fused filament fabrication (FDM/FFF)
