Developments in precision product manufacturing for laser-sintering

Laser sintering is often used for design studies, prototypes and in tooling and moulding, i.e. in automotive and air industry applications. However, limitations in accuracy, surface quality, material properties, and process reliabilities still remain today and narrow the range of applications. Among other things, these reasons prevent clients in solving their needs. An add-on solution, in terms of an additional Micro-Mixing-Dosing (MMD)-system is proposed to be assembled into the laser sintering machine to accomplish a localized property distribution. This paper describes a new state-of-the-art route in manufacturing precision parts with various selected property profiles and an outlook in forecasting final product properties.
