The IAMA system with Automatic Virtual Metrology (AVM) technology can enable a 3D printing laser powder bed fusion (LPBF) machine to achieve the world＇s first innovative capability of online layer-to-layer quality predictionfeedback control, which improves the final product quality such as tensile strengthsurface roughnessrealize the goal of nearly Zero Defects of all products.

The IAMA system offers both optimized parameters based on different metal powders timely layer-by-layer quality evaluation by AVM according to the melt-poolpowder-coating features obtained by coaxialoverview cameras. IAMA can make recoatinglaser polishing decisions in seconds to timely re-process the current layer for ensuring the quality. By integrating IAMA into an LPBF machine, the tensile strengththe surface roughness of the final products can be significantly improvedreaching the goal of nearly Zero Defects in all products.

The IAMA system stands out from the other competitive products based on the advanced functions (as shown in Figure 1) include layer-by-layer surface roughness prediction, layer-to-layer powder bed control,layer-to-layer laser polishing control. IAMA can make recoatinglaser polishing decisions in seconds to re-process the current layer if necessary for ensuring the quality so as to achieve the goal of nearly Zero-Defects of all the products.
