Additive manufacturing is the layer-by-layer construction of components. Plastics, metal and composite materials can be used as powder materials. Digital 3D design data is the basis of the process. Originally used as a tool for the production of samples, prototypes and small series, this type of manufacturing has also established itself in series production in a wide variety of application areas. Sill Optics offers various lenses that are used in additive manufacturing, such as the S4LFT0910-328 scan lens. Thanks to the large scan field, comparatively large components can be additively manufactured or the process speed can be significantly increased by using several lasers.
