Abstract: An additive manufacturing system, and corresponding method, prints a sacrificial component using a 3D printing system that includes a spreading mechanism for spreading unbound powder to form layers of a powder bed and a printing mechanism for jetting binder fluid into the unbound powder to form the sacrificial component. The system forms the sacrificial component with a feature that provides a resistive force to a shear force imposed by the spreading mechanism during the spreading. The system prints a part with the 3D printing system in a coupled arrangement with the sacrificial component. The coupled arrangement in combination with the resistive force is sufficient to immobilize each printed layer of the part to resist the shear force imposed by the spreading mechanism during spreading of the unbound powder above each printed layer of the part. After printing, and before or after post-processing, the part and sacrificial component are separated.

Abstract: Material for packaging—and package or receptacle made of such material—that contains a particular aluminized polymeric film with emissivity of equal to, or less than 0.10 and yet sufficiently thin to withstand and satisfy industrial requirements of the recycling process due to substantially complete oxidization of aluminum during the recycling.

Protective coating is configured to not raise emissivity of the aluminized surface above the 0.10 value and, at the same time, to still allow for the aluminum material it covers to be removed due to becoming fully oxidized and corroded in the heat and at humidity levels used in the recycling/repulping process. Proposed configuration permits the aluminum of the packaging material to be included in the recycled portion of the packaging material.
