Agilus shore a30

The PFG and the NFG consisted of several layers of different 3D‐printed materials, as shown in Figure S1, Supporting Information. A multi‐material printer (Connex500, Stratasys, Ltd.) was used to print the top, hole, and bottom layers with a rigid plastic (VeroClear, Stratasys, Ltd.), and the poppet and O‐ring with a rubber‐like material (TangBlackPlus/Shore A30, Stratasys, Ltd.). A multi‐material printer (Objet500 Connex3, Stratasys, Ltd.) was used to print the membrane layer with a composite material DM 9840/Shore A40 (primary material: VeroClear, secondary material: Agilus/Shore A30, Stratasys, Ltd.) for improved mechanical properties. Furthermore, a 400‐µm thick membrane core was printed with DM 9870/Shore A70 (primary material: VeroClear, secondary material: Agilus/Shore A30, Stratasys, Ltd.) inside the 800‐µm thick diaphragm membrane as a reinforcement. All layers were assembled using a commercial instant adhesive (LOCTITE 4850, Henkel AG & Company, KGaA), including silicone tubing (1.6 mm ID and 3.2 mm OD, McMaster‐Carr) on each terminal. A surface primer (LOCTITE SF 770, Henkel AG & Company, KGaA) was used to promote adhesion between the silicon tubing and 3D‐printed parts. Finally, male and female of plastic quick‐turn tube couplings (for 1.6 mm barbed tube ID, McMaster‐Carr) were used to connect the fluidic gates.
