Abstract

Additive Manufacturing (AM) of metals is passing
the research stage and finding application in the industrial
environment as a manufacturing technology of choice. However,
the quality of products fabricated using metal AM technology
could be considered inferior when used in batch manufacturing.
Quality is generally defined as conformance to specification and
is inversely proportional to process variation. Variation in a
process signifies the number of possible defects per million
opportunities in a given production. This gives rise to the need
to characterize process variation to improve quality. This paper
explores the characterization of variability in laser powder bed
fusion (LPBF) AM of metals to improve the quality of part
production with specific focus on batches. It summarizes the
factors that influence the variation and discusses the tools used
to improve part quality.
