ABSTRACT Rubber-based polymers with high carbon black content can be three-dimensionally (3D) printed using the additive manufacturing of elastomers process. However, high-viscosity materials limit printing resolution, making it difficult to produce fine structures and high-precision parts, especially two-component (2K) parts. The viscosity a rubber compound used for rod seal applications was reduced adjusted Nipol® 1312 liquid alkyl sulfonic phenyl ester Mesamoll® II as plasticizers lower...
The additive manufacturing (AM) of elastomeric parts based on high-viscosity reinforced rubbers has increasingly become a topic scientific research in recent years. In addition to the viscosity, which is several decades higher during processing than viscosities thermoplastics, flowability compound after printing process and necessary chemical crosslinking printed component play decisive role producing an elastic, high-quality, geometrically stable part. After first technological achievements...
Abstract The delivery time of expendable items can be quite high despite today’s sophisticated logistics and production systems. In the case dynamic rod seals for hydraulic applications, this last weeks or even months. A possible solution to avoid shutdowns fast using additive manufacturing (AM), at least use these parts until conventionally produced spare arrive. research question addressed in study is whether it produce functional way leakage. paper starts with an introduction topic...
"Hydraulic rod seals are crucial machine elements in a lot of applications. Malfunction can cause huge economic loss by long shutdown times for repair. Especially if equipment is used remote areas the nature, malfunction also severe environmental damage spilled polluting hydraulic fluid. The delivery time dynamic applications last weeks or even months as these often manufactured on demand. In addition, years have shown that geopolitical incidences like war pandemic impact international...
Additive manufacturing (AM) technologies make strong progress in these years and impact seals as well. However the surface quality of AM is typically lower compared to from conventional production. For example Fused Filament Fabrication produces parts with a regular string-like structure. This structure generated thin moving nozzle that extrudes melted filament material strings. The size order fluid film thickness dynamic rod seal. A fluid-structure interaction (FSI) fully coupled...

In a recently started DFG-funded research project, the suitability of additive manufacturing methods and materials for production dynamic rod seals is investigated.Initially, range was defined, which shall be considered in next phases project.For one those methods, Fused Filament Fabrication (FFF), commercially available TPU-materials were analyzed.A set potential has been defined analyzed with respect to different criteria.These criteria comprise processability, static stiffness material,...
