The invention adds a current measurement device such as a NF Corporation, CA5350 low-noise current preamplifier and electrical connections to a conventional laser powder bed fusion additive manufacturing system (Figure 1). The powder bed is electrically isolated from ground and the powder bed is electrical connected to the current pre-amplifier.
Colorado School of Mines (Mines) requires a laser powder bed fusion (PBF) additive manufacturing machine (AM) capable of fabricating metallic articles using standard and non-standard alloys in support of a project exploring metal AM for fabricating structural components for the US defense community. ...

Added: Oct 31, 2017 12:35 pm • The machine should be a Powder Bed Fusion system, as defined by the ASTM as "An additive manufacturing process in which thermal energy selectively fuses regions of a powder bed."(REF: International Standardization Organization/ASTM 52900-15 Standard Terminology for Additive Manufacturing.) • The machine's thermal energy source should be an electron beam with a minimum of 3000 watts power.
The Production Systems Group (PSG) at NIST conducts research in metals-based additive manufacturing to develop and deploy advances in measurement science that will enable rapid design-to-product transformation. Part of this research involves developing a controller for the laser powder bed fusion (LPBF) additive manufacturing testbed.
