Emmanuel Segura-Cárdenas ( Tecnologico de Monterrey, Escuela de Ingenieria y Ciencias ) and Luis Fernando Velásquez-García ( MIT ) detail the results of a recent study in ‘ Additively Manufactured Robust Microfluidics via Silver Clay Extrusion ,’ explaining how they created a proof-of-concept microfluidic capable of decomposing hydrogen peroxide.
While most microfluidics are composed of silicone, such materials are incapable of handling high temperature or pressure—and they are not very compatible with solvents. Metal could be considered a suitable choice for the development of sturdy microfluidic devices, but currently, most of that technology is geared toward the creation of thin films and wafer bonding.
“In addition, fabrication approaches such as electric discharge micromachining  and micro milling  have been explored to implement metal microfluidics, but these manufacturing processes are very expensive, very slow, and require specialized tooling.” Schematic of 3D printing process to create metal clay-extruded objects Today, […]
