  • Patent number: 9321608
    Abstract: A spool assembly comprising a housing structure, a spool rotatably retained in an interior region of the housing structure, and a sealed sheath encasing the housing structure to define a barrier for the encased housing structure and the rotatably retained spool. The spool assembly further comprises a locking arm disposed outside of the sealed sheath and configured to operably engage the spool through the sealed sheath and through the housing structure in a manner that does not penetrate the sealed sheath, where the locking arm prevents the spool from rotating relative to the housing mechanism when operably engaged with the spool. The locking arm may disengage from the spool in a hands-free manner when the spool assembly is loaded into a bay of an additive manufacturing system.

    Abstract: The present invention is a metallized shrinkable label and a method for producing the same. The label of the invention is composed of a shrinkable film base and a graphic. The graphic is created by combining pigmented inks, a metallic coating and a shrink-resistant coating which is printed in a predetermined pattern with gaps so that upon exposure of the label to heat, the gaps close thereby forming a continuous graphic layer. Advantageously, the shrink-resistant coating minimizes discoloration and pleating of the metallic coating.
