ChannelCOMB, a consecutive flow distributor, was constructed by additive manufacturing (AM) for experimental validation. The feasibility of using AM was experimentally analyzed for two techniques: stereolithography (tolerance of 50 mu m) and fused deposition modeling (tolerance of 100 mu m). For the best ChannelCOMB configuration, SLA printing shows a maximum of ca. 4 % in flow deviation, while FDM has a maximu...
