Abstract

This paper describes three dimensional (3D) microfluidic devices fabricated by an injection molding-based additive manufacturing with standard equipment for soft-lithography. The method achieves 3D fabrication without specific instruments or water-soluble support material. It provides the same level of minimum membrane thickness as a high end model commercial 3D printer, and the bond strength between the membranes have a sufficient pressure resistance to the flow of water with a syringe pump. Finally, two types of 3D microstructures were fabricated by the method: the 3D fractal structure called Menger sponge, and a channel within a channel structure for 3D sheath flow.
