About This Webinar
Contemporary manufacturing processes go beyond simple stamping, molding, or CNC machining steps, and adopt more advanced technologies, such as additive manufacturing and 3D printing. While the gains in design flexibility and part complexity are obvious, there are many process parameters behind the scenes that, together with the necessary finishing steps, are critical to meeting roughness, aesthetic, or functional requirements.

This webinar illustrates how advanced optical profiling accurately assesses complex surface textures through areal roughness parameters (from the ISO25178 norm), as well as how the same profiler can be used to optimize subsequent finishing steps, from bed fusion of metallic powder to polymer-printed surfaces. Attendees will learn how efficient areal roughness parameters within these new manufacturing processes supersede Ra, and which parameters to select that will directly tie to the effectiveness of processes, the shininess/appearance of parts, and the quality of the 3D printing. A Q&A session will close the event.

Who should attend:
Quality control, metrology, material development, additive and 3D-printing manufacturing engineers, finishing process designers (e.g., blasting, tumbling, polishing, laser texturing), and others interested in controlling the quality of the finishing steps for additive-manufactured or 3D-printed parts. This webinar is applicable to a variety of industrial markets, including aerospace, automotive, energy, medical, and semiconductors.
