Stylus and Optical Profilometry Webinars

Surface Finish Optimization for Advanced Manufacturing by Optical Profiler

Understand how and why to use areal roughness parameter measurements to improve surface finishing processes

Controlling surface texture is critical to the function, lifespan, and aesthetics of product parts and components

This webinar focuses on how advanced optical profilers can be used to accurately assess and gauge ISO 25178 compliance of complex surface textures through the Sa areal roughness parameter

Webinar Summary

Today's manufacturing processes go beyond simple stamping, molding, or CNC machining. They often include advanced processes--like imprinting specific textures on surfaces, This now-common surface finishing process in manufacturing aims to improve the function of parts and components, extend their useful life, or enhance their aesthetics.

Geared towards viewers like quality control engineers, metrology engineers, material development researchers, application engineers for additive and 3D printing manufacturing, and designers of finishing means, this webinar explores:

The mechanisms behind our advanced optical profilers' ability to accurately assess complex surface texture through areal roughness parameters in compliance with ISO 25178;
How these same profilers can be used to optimize manufacturing processes and control the quality of the imprinting process; and
Practical industrial cases, ranging from an mechanical part to a polymer 3D-printed surface made via additive manufacturing.

This webinar was presented on June 13, 2020.

Presentation Overview

Presentation Lenght	Title	Presenter	Abstract
30 min	Finishing Process for 3D Printed Polymer Surfaces	Samuel Lesko, Ph.D.	This presentation explores the use of optical profiler techniques for post-processing and quality control in 3D-printed polymer manufacturing. In the included case study, Bruker optical profilers are used to assess and compare the areal parameters of a 3D-printed polymer part that has been subjected to different post-processing/finishing processes. Optical profilometry enables us to quantify and rank these finishing processes and select optimum processes to meet ISO 25178 standards.
30 min	Surface Texture and Paint Adhesion	Donald K.Cohen, Ph.D.	This presentation discusses how texture measurements of functional surfaces are limited by exploration equipment and how the SMART methodology for texture functionality research guides researchers toward the correct answers.
35 min	What Texture for What Functionality and Howto Characterize It?	Raphaël Delttombe, Ph.D.	This presentation covers the use of 3D optical profilometry, and multi-spectral analysis, to demonstrate correlation between the base substrate texture features to the final paint appearance.
20 min	Live demo of the ContourGT-X	Samuel Lesko, Ph.D.	-
