Abstract: A method is provided for predicting material properties of a part to be additive-manufactured. The method comprises additive-manufacturing a plurality of standard parts, and obtaining thermal profiles at select predetermined locations of physical samples of the plurality of standard parts during additive-manufacturing of the plurality of standard parts. The method also comprises storing the thermal profiles and corresponding material properties of the physical samples of the plurality of standard parts in a database. The method further comprises running a machine-learning algorithm to predict material properties of the part to be additive-manufactured based upon the thermal profiles and corresponding material properties of the physical samples of the plurality of standard parts stored in the database.

Abstract: The inventive multipole acoustic wave logging method includes the steps of introducing a 2.sup.n -pole acoustic wave into a virgin earth formation surrounding a borehole but separated from the borehole by an invaded zone, where n is an integer greater than zero, and detecting the refracted arrival of the 2.sup.n -pole acoustic wave. The inventive apparatus includes means, separated from the borehole wall during operation, for generating a 2.sup.n -pole acoustic wave that will propagate through the borehole fluid and thereafter into the virgin earth formation. If the 2.sup.n -pole acoustic wave is a compressional wave, the compressional wave velocity of the virgin formation is determined from repeated measurements, at successively increased longitudinal spacings between the points of generation and detection of the 2.sup.n -pole wave, of the time interval between detections of the refracted arrival of the 2.sup.n -pole acoustic wave by the two detectors. If the 2.sup.
