Additive manufacturing (AM) technology, also known as 3D printing, has transitioned
from concepts and prototypes to part-for-part substitution and the creation of unique
AM-specific part geometries. These applications are increasingly present in demanding,
mission-critical fields such as medicine and aerospace, which require materials with certain
thermal, stiffness, corrosion, and static loading properties. To advance in these arenas, metallic,
ceramic, and polymer composite AM parts need to be free from discontinuities.
The manufacturing processes have to be stable, robust, and repeatable. And the nondestructive
testing (NDT) technology and inspection methods will need to be sufficiently capable and reliable
to ensure that discontinuities will be detected to prevent the components from being accepted for
use. As the second installment of a six-part series of SAE EDGE™ Research Reports on AM, this one
discusses the need, challenges, technologies, and opportunities for NDT in AM.
NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging,
but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™
Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution
of identified issues. SAE EDGE™ Research Reports are not intended to resolve the challenges they
identify or close any topic to further scrutiny.
