A tensile bar, including a first support structure, a second support structure, and a plurality of tensile members extending between the first support structure and the second support structure, each member of the plurality of members extending at least in part in a direction other than longitudinally axially of the tensile bar and from a first point on the first support structure, to a second point on the second support structure, a line between the first point and the second point being parallel to a longitudinal axis of the tensile bar. A method for making the tensile bar, including applying a material from an additive manufacturing machine to a build plate in the form of a layer of the tensile bar. A borehole system, including a borehole in a subsurface formation, a string in the borehole, and a tensile bar disposed within or as a part of the string.

Shock resistant and load tailored tensile bar method, and system

A method of calibrating a laser of an additive manufacturing system involves processing a test pattern with the laser while varying one or more of laser power and/or scan speed. Thermal energy emitted from the resulting meltpool is measured while processing the test pattern. The power of the laser is calculated using a relationship between volumetric energy density and the thermal emissions, and the laser power is adjusted based on the calculated laser power. An additive manufacturing system for performing such a method may include a laser, a thermal sensor configured to measure meltpool thermal emissions, a processor configured to calculate a laser power based on the measured meltpool thermal emissions of the test pattern, and a controller configured to adjust the laser power based on the calculated laser power.

A process for producing a powder witness coupon including additively manufacturing a container simultaneously with a primary part, filling at least a portion of the container with a feed material employed for the part simultaneously with the additive manufacturing of the primary part, and sealing the container during the additive manufacturing of the primary part. An in-situ feed material powder witness coupon including a container additively manufactured simultaneously with a primary part, and a plurality of individual chambers within the container, at least one of the chambers being removable intact from the container. Further, a method for enhancing examination of feed material in an additively manufactured part including additively manufacturing a container simultaneously with a primary part, capturing feed material, density and environment in the container, and sealing the container.
