In this paper, three metallic mould inserts for fabrication of polymer microfluidic devices were produced using different methods. Firstly, metallic glass mould insert was cut by high speed micro-milling. Secondly, 316L stainless steel mould insert was made by micro metal injection moulding (μMIM) using D50 = 4 μm powder. Finally, 316L stainless steel powder with a smaller particle size of D50 = 2 μm was used to produce mould insert in order to improve surface quality of the mould insert. The geometry and surface roughness of micro-features on the three mould inserts are viewed and compared.
