Abstract

The raising importance of stereolithography printers for rapid prototyping of microfluidic chips is due to the combination of affordable machinery and high resolution. However most commercial printing materials have low chemical resistance to solvents and strong acids. Perfluoropolyethers (PFPE) are a class of materials which show a high chemical resistance. Here we present a new resin formulation using PFPE methacrylates which allows 3D printing of microfluidic structures with a channel size of 200 μm and a transparency of 90% in the visible light region. We further show that using an adapted PFPE resin formulation superhydrophobic surfaces can be printed.
