Applications of FDM printing of transparent PS. (a) A 2.5-dimensional microfluidic tesla-mixer with a square channel cross-section of 600 µm width and height. A blue and a yellow dye were mixed along the cascade. (b) A 2.5D mixer cascade with a square channel cross-section of 600 µm width and height. The mixing of a yellow and red dye demonstrates the creation of mixing gradients. (c) An FDM-printed microfluidic structure with two intertwining 3D microchannels of 600 µm width and height filled with fluorescent dyes to demonstrate the three-dimensionality. (d) An exemplary FDM-printed customized well-plate (scale bars 10 mm).
