Powder Bed Layer Geometry

Abstract

This paper investigates the measurement of machine performance errors associated with the powder bed geometry of a commercially available laser additive manufacturing (AM) machine. The methodology is based on existing ISO/ANSI standards as employed in computer numerically controlled material removal type machinery. The paper describes the design of the tests and sign conventions. A discussion is presented on which error sources can affect both the powder layer thickness and part geometry. Finally, conclusions are drawn regarding the applicability of existing standards to LPBF machine metrology and includes a discussion of where modifications may be necessary.
