In this study, we show a new, cost effective and straightforward method to fabricate stainless steel (SS) microtextures with various geometries. We were able to design and texture a durable Ni mould insert by a microworking robot technique. Furthermore, the obtained micmtextures were replicated onto stainless steel surfaces by metal injection moulding. A computer-controlled program enabled precise control of the spacing between the textures giving a broad choice for surface design. Surface geometries, such as micropillars and micropits with different dimensions, were produced on planar and curved surfaces. These results introduce a new platform for mass production of microtextured stainless steel surfaces with high surface control. The obtained surfaces have potential applications by meeting the demands of reducing surface contact and providing surface protection from mechanical damage.
