Special Issue Information

Dear Colleagues,

Additive manufacturing (AM), also known as 3D printing, has emerged as a promising technology for fabricating polymer-based products with complex geometries. The flexibility in fabrication offered by AM also brings complex mechanical properties. Research on these properties is important for understanding the limitations and potential of AM technology for various applications. Improved mechanical properties of printed parts also expand the range of polymeric applications for AM technology in various fields, such as aerospace, the automotive industry, and biomedical engineering.

The mechanical properties of AM polymers are strongly influenced by various process parameters. Therefore, it is important to investigate the effect of these parameters on the mechanical properties of the printed parts. This Special Issue aims to provide an overview of the recent advances in the mechanical properties of additively manufactured polymers, covering a range of topics, such as the material characterisation of AM polymeric structures and the optimisation of process parameters to improve the mechanical properties.

Abstract
In recent years, additive manufacturing technology, particularly in plastic component fabrication, has gained prominence. However, fundamental modelling of the influence of materials like ABS, PC, and PLA on tribological properties in fused deposition modeling (FDM) remains scarce, particularly in non-lubricated, oil-lubricated, and grease-lubricated [...] Read more.
In recent years, additive manufacturing technology, particularly in plastic component fabrication, has gained prominence. However, fundamental modelling of the influence of materials like ABS, PC, and PLA on tribological properties in fused deposition modeling (FDM) remains scarce, particularly in non-lubricated, oil-lubricated, and grease-lubricated modes. This experimental study systematically investigates the effects of material type, lubrication method, layer thickness, and infill density on FDM component tribology. A tribology analysis is conducted using a TRB3 tribometer. The results indicate a coefficient of friction (CoF) range between 0.04 and 0.2, generally increasing and decreasing with layer thickness and filler density. The lubrication impact hinges on the material surface texture. The study models the intricate relationships between these variables via full-factor analysis, showing a strong alignment between the modelled and measured friction coefficients (an average error of 3.83%). Validation tests on different materials affirm the model’s reliability and applicability. Full article
