Abstract: A barbeque grill scraper and related methods of use that utilize a scraping end formed of a heat-responsive material to remove char and other debris from the grilling surface. The grill scraper includes a conformable scraping edge formed of the heat-responsive material. As the conformable scraping edge is drawn back and forth along the heated grilling surface, a combination of pressure applied by a user as well as the heat of the grill surface results in the formation of individual grooves along the conformable scraping edge, wherein each groove is formed to match an upper profile of the grilling surface. Over time, the grooves fully conform to the upper profile of the grilling surface such that an entire cooking surface can be scraped clean of char and debris.

Abstract: A computer-readable medium includes recorded instructions for performing a method of improving evacuation gas flow performance of an additive manufacturing build chamber. Instruction execution by a processor of a host computer device causes the processor to receive an input data set inclusive of flow field data of an inert gas through the build chamber, and an improvement metric operable to characterize flow improvements therein. The processor generates a flow field data set in response to the input data set, and extracts evacuation streamline data from the flow field data set.
