Packaging Review

2024

No. 1

6--15

Appropriate packaging is essential to protect products from external contamination, physical damage or food spoilage. The latest innovations in the packaging industry are mainly limited to the development of new polymeric barrier materials and composite or green, environmentally friendly materials. However, recently, new active, and/or intelligent (smart) packaging is being developed that can extend the shelf life of a product, keep it in good condition and help control the quality of food products. This review presents the latest developments and applications of additive manufacturing in the production of smart food packaging.

Odpowiednie opakowanie jest niezbędne, aby chronić produkty przed zanieczyszczeniami z zewnątrz, uszkodzeniami fizycznymi lub zepsuciem się żywności. Najnowsze osiągnięcia w branży opakowań ograniczają się głównie do opracowania nowych polimerowych materiałów barierowych oraz kompozytowych lub ekologicznych materiałów przyjaznych dla środowiska. Jednak ostatnio opracowywane są nowe opakowania aktywne i/lub inteligentne (smart), które mogą wydłużyć okres przydatności do spożycia produktu, utrzymać go w dobrym stanie i pomóc kontrolować jakość produktów spożywczych. W niniejszym artykule przedstawiono najnowsze osiągnięcia i zastosowania wytwarzania przyrostowego w produkcji inteligentnych opakowań do żywności.

A study on the influence of printing orientation in metal printing using material extrusion technology on the mechanical properties of 17-4 stainless steel products

This study investigated the influence of print orientation on the mechanical properties of 17-4 PH stainless steel parts fabricated using material extrusion technology. Tensile test specimens were 3D printed in different orientations (flat, on-edge, and upright), and their mechanical properties were evaluated. The results showed that the print orientation significantly affected the ultimate tensile strength, yield strength, and elongation at failure of the specimens. The flat and on-edge orientations exhibited similar mechanical properties, while the upright orientation resulted in lower strength and higher fracture susceptibility. Hardness measurements also indicated variations in hardness distribution among the orientations. The findings emphasize the importance of optimizing the print orientation parameter to achieve desired mechanical characteristics in 17-4 PH stainless steel parts.

Mechanical properties and geometric accuracy of angle-shaped parts manufactured using the FFF method

art. no. e137387

The paper presents the results of research on the influence of the parameters of Fused Deposition Modelling (FDM) on the mechanical properties and geometric accuracy of angle-shaped parts. The samples were manufactured from acrylonitrile butadiene styrene (ABS) on a universal machine. A complete factorial experiment was conducted. The results indicated that the critical technological parameter was the angular orientation of the sample in the working chamber of the machine. The results were compared with the results of research performed on simple rectangular samples. A significant similarity was found in the relationships between the FDM parameters and properties for both sample types.
