Special Issue Information

Dear Colleagues,

By definition, additive manufacturing (AM) is a technology that constructs 3D complex geometries by adding layer-upon-layer of material based on the digital computer-aided design model. The nature of this construction has brought several advantages for this production method compared to conventional subtractive manufacturing (CSM). The ability to produce complex structures, tailoring properties, as well as sustainability and ecological issues, such as less energy consumption and material waste, are taken into account as benefits of AM compared to CSM. However, the nature of this production has its own drawbacks like the formation of rough surfaces and porosities on the surface and beneath layers, which is detrimental for the lifetime of AM components. On the other hand, as a result of the complicated physical phenomena taking place during fusion and deposition, the AM material exhibits inadvertent anomalies and lacks certifiable structural integrity and/or sufficient quality for engineering applications. Therefore, prior to extending the range of applications of such promising technology and being replaced by conventional CSM, certifications regarding mechanical and tribological properties, surface integrity, and fatigue strength are required.

This Special Issue welcomes articles addressing surface integrity, fatigue life, corrosion, and wear resistance of AM material by optimizing the process window or by applying a post-processing plan. The submitted articles should outline the structural integrity of metallic materials (as well as other types of materials) that are produced using different variants of AM technologies. 

We look forward to your submissions.

Due to a lack of investigated materials for the additive manufacturing of multi-use functional parts in bioprocess engineering, this study aimed to evaluate the influence of multiple autoclaving cycles on the properties of a heat-resistant material (xPeek147) printed with vat photopolymerization. Sample bodies were tested regarding their mechanical properties of tensile strength, elongation at break, and Charpy impact, as well as surface properties of roughness and wettability after up to 50 autoclaving cycles (121 °C, 2 bars, 15 min). The tightness was checked after up to 20 cycles, and accuracy was inspected for manufactured benchmark bodies after up to 10 autoclaving cycles. The reported results showed no significant changes in tensile strength, elongation at break and Charpy impact after 20 cycles, but a significant decrease after 50 autoclaving cycles, accompanied by microcracks in the structure. Regarding the surface properties the material retained its hydrophilicity, and the surface roughness was not affected significantly. No changes in tightness occurred, and the benchmark bodies for dimensional changes showed no process-relevant deviations. Through the investigations, a material for the additive manufacturing of multi-use functional parts for bioprocess engineering was identified. Additionally, a testing method for materials with the same intended application was provided. Full article
