Figure Lengend Snippet: The profile of a microfluidic chip with a single 3D-printed molding technique. ( a ) Leakage-free 3D-printed microfluidic chips enabled by gyroid infill pattern: structural integrity enhancement through TPMS design. ( b ) Fluid leakage in 3D-printed chips with twelve other infill patterns (e.g., rectilinear, triangular, and hexagonal): structural deficiencies from reduced integrity and mechanical strength. ( c ) Optical clarity and structural homogeneity of 2-mm-thick 3D-printed PMMA microfluidic chips: transparency benchmarking against a microreactor and a 50-cent CNY coin for scale reference.
Article Snippet: During the preliminary phase of process development, FDM 3D printing of PMMA filament was simulated using COMSOL Multiphysics software v5.5, a finite element analysis software platform for multiphysics computational modeling.
