New Guide for Evaluating Post-processing and Characterization Techniques for AM Part Surfaces

1. Scope

The promotion of knowledge, stimulation of research and implementation of technology through the development of standards for additive manufacturing technologies. The work of this Committee will be coordinated with other ASTM technical committees and other national and international organizations having mutual or related interests.

Keywords

Surface finishing; surface roughness; surface metrics; profilometry; white light interferometry; scanning laser microscopy; focus variation microscopy:

Rationale

Additive Manufacturing (AM) has enabled users to build complex geometries. However, finishing and characterizing the surface quality of these complex geometries is still a challenge. It has also been observed that AM parts usually have poor as-built surface quality that affects the fatigue and flow characteristics. Thus, understanding and standardizing surface finishing processes becomes a critical component of the AM supply chain. This standard will be used by the additive manufacturing community, the nondestructive testing community, and the fatigue and fracture community for surface characterization techniques and metrics.

The title and scope are in draft form and are under development within this ASTM Committee.
