Sigma Labs: full paragraph in Additive Industries publication:

"For validation of the printed parts, Additive Industries
initiated collaboration with the US company Sigmalabs:
its pyrometer and photo diodes were incorporated in the
functional model for monitoring the melt pool. The
information from these sensors can be combined
intelligently to produce a statement about the quality of the
printing process. This information has to be correlated with
the outcomes of tests of, for example, tensile strength and
fatigue behaviour in order to be able to be conclusive about
the quality of the printed product. Monitoring the external
geometry of the product during printing is not useful
because of thermal effects (warping, shrinking after
cooling). After the product has cooled down, measurements
can be made with a 3D scanner or a coordinate
measurement machine. Their results will support the
end qualification of the printed product."
