Abstract: A computing device for controlling the operation of an additive manufacturing machine comprises a memory element and a processing element. The memory element is configured to store a three-dimensional model of a part to be manufactured, wherein the three-dimensional model defines a plurality of cross sections of the part. The processing element is in communication with the memory element. The processing element is configured to receive the three-dimensional model, determine a path across a surface of each cross section, wherein the path includes a plurality of parallel lines, calculate a power for a radiation beam to scan each of the lines, such that the power varies from line to line non-linearly according to a length of the line, and calculate a scan speed for the radiation beam for each of the lines, such that the scan speed varies line to line non-linearly according to the power of the radiation beam.

Abstract: A system and method for improving the simulation of machining effects in an object on computer-aided design models by imparting micro level machining stress and strain effects on a macro part model in a time-realistic manner. A reference machining operation is performed on a micro reference model. A transfer map based on a pre-machining stress-strain gradient and a post-machining stress-strain gradient is created. A machining operation is then performed on the macro part model with the pre-machining stress-strain gradient and the post-machining stress-strain gradient being mapped to the macro part model. The macro level machining operation and mapping are performed in a time-realistic manner.

Abstract: A composite material comprising a metal matrix and nanocellulose supplement. The metal matrix is formed of a metal base material and may be monolithic throughout the composite material. The nanocellulose supplement improves a material property of the metal matrix and is formed of a nanocellulose supplement material dispersed in the metal base material. Importantly, the nanocellulose supplement material does not become damaged when the composite material is formed.
