Abstract: A process for producing a high density aluminum alloy part from a green part like those produced by binder jet additive manufacturing is described. The process utilizes a build powder that includes a densification aid mixed with the aluminum alloy powder and gets incorporated into the green part during the printing process. In some cases, a continuous high flow of nitrogen gas and controlled heating of the green part and provides a high density aluminum alloy part exhibiting densities of 95% or greater.

Abstract: A method and a system for analyzing a physical characteristic of a film sample are described herein. The system includes a material holder system configured to hold the film sample; and a tear analysis device configured to tear the film sample and measure a characteristic of the tear. The movable system is configured to move the film sample in the material holder system to the tear analysis device.

Abstract: A system and method for performing a tear test are described herein. The system may include a fixed clamping station configured to hold a first portion of a film specimen and a movable clamp coupled to an actuator, the movable clamp may be configured to hold a second portion of the film specimen. The movable clamp may be configured to move in a direction away from the fixed clamping station to tear the film specimen. The system may include a slitter blade configured to cut the film specimen at a location between the fixed clamping station and the movable clamp. The system may include a load cell coupled to one of the fixed clamping station and the movable clamp. The load cell may be configured to measure a force associated with tearing of the film specimen. The actuator may be configured to manipulate the movable clamp along a trajectory.
