Abstract
Hybrid additive manufacturing aims to combine the flexibility of additive processes with the high productivity and quality of material removal processes. However, when combining these three decision factors with the final cost of the part, how does the decision-making process change? In this study, two additive manufacturing processes were chosen as case studies for producing a standard part: fused filament fabrication (FFF) and big area additive manufacturing (BAAM). These parts were manufactured using four different combinations of these processes, with or without machining in the same setup. The conditions were: FFF process, machining (milling and drilling),hybrid additive manufacturing with BAAM and machining and additive manufacturing with FFF and machining. The results were evaluated by comparing manufacturing time, cost, material volume, dimensional tolerances, surface roughness, and flexibility (setup time). Under the evaluated conditions, hybrid additive manufacturing with BAAM presented the best results balancing all proposed criteria, with the lowest cost and material volume consumption, while maintaining similar dimensional and surface quality compared to the other processes. FFF represents the most flexible additive manufacturing process, with the shortest setup time for preparation. Machining had the shortest manufacturing time, due to its high removal rates in the evaluated case. It is expected that these results and discussions will support the composition of other cases for a balanced evaluation of the performance of hybrid additive manufacturing processes.
