A rigid polymer domed food container system suitable for heated food products is described. The semiconductor memory device includes first and second address buffer units. Some embodiments include a flexible assembly for each storage component, including at least one flexible element and at least one swaged cam for each flexible element. In addition, we have automated the analysis of survival by the use of a fluorometric plate reader that quantitates the degree of fluorescence within each well. The device uses multiple writing heads to write simultaneously different segments of the object and thus complete the object manufacture in a shorter time as compared to a one head additive manufacturing device.
