Abstract: A replaceable printer component includes a memory device to store a tag encryption mask and data. The data is stored in a plurality of blocks of the memory device wherein each block is defined by a tag. The tag encryption mask indicates an encryption status of each block of the memory device defined by the tag. The replaceable printer component includes a communication link to communicatively link the memory device to a printer controller when the replaceable printer component is installed in a printing system. The tag encryption mask is stored within a header of the memory device. Each tag defines a type and a length of the data stored in the blocks.

Abstract: Certain examples described herein relate to replaceable production material containers for additive manufacturing systems. In an example of a replaceable production material container, an electrical storage device provides at least one production material characteristic to an element of an additive manufacturing system. In certain examples, the electrical storage device stores a range parameter for indicating a production material characteristic offset value in a plurality of production material characteristic offset values. In certain examples, the electrical storage device stores a proportion parameter for determining the at least one production material characteristic on the basis of the production material characteristic offset value.
