US 2024/0390890 A1 · MULTI-MODALITY ADDITIVE MANUFACTURING OF MICROFLUIDIC SYSTEMS

Abstract

A first structure of a microfluidic system is fabricated via a first additive manufacturing process. The first structure has at least one first fluidic port and at least one first conduit. Each first conduit connects to one of the at least one first fluidic port. A second structure of the microfluidic system is fabricated on the first structure via a second additive manufacturing process. The second structure has at least one second conduit. The second structure is fabricated such that the at least one second conduit is sealed to the at least one first fluidic port and such that the at least one first conduit is in fluid communication with the at least one second conduit. The second additive manufacturing process employs ex situ direct laser writing, while the first additive manufacturing process employs an additive manufacturing modality different from the second additive manufacturing process.
