About

Marco Speich is a precision manufacturing researcher whose work centers on the fabrication of high-quality molds for polymer optics production. His research addresses a critical bottleneck in the optics industry: the efficient, high-precision manufacture of steel molds used in injection molding processes for optical components ranging from ophthalmic lenses to sensors and sunglasses. Speich's most significant contribution lies in streamlining the mold fabrication process chain. His influential 2011 work demonstrated how a traditional five-step manufacturing sequence could be reduced to just three steps, while maintaining the stringent surface and form quality demands of optical applications — a finding that has since accumulated 14 citations and informed subsequent research in the field. Building on this foundation, he explored precision mold manufacturing for medium- to high-quality polymer optics in 2012, and further investigated polishing as a finishing stage in 2014. More recently, Speich investigated Fluid Jet Polishing as an innovative alternative to the manual finishing methods that typically rely on skilled craftspeople, pointing toward greater automation and consistency in mold production. Collectively, his body of work has made meaningful contributions to manufacturing efficiency and optical quality in the growing polymer optics sector.
