Ink development for the additive manufacturing of strong green parts by layerwise slurry deposition (LSD‐print)

Abstract Obtaining dense fine ceramics by the binder jetting additive manufacturing process is challenging. A slurry‐based process, such as layerwise slurry deposition (LSD‐print) can enable printing of ceramic parts. This work describes a procedure to develop and qualify suitable ink manufacture silicon carbide green parts LSD‐print. Not only printability but also compatibility with powder bed effect binding agent on properties are considered. Both aspects important obtain high strength, which necessary for large or thin‐walled Characterization methods, rheological surface tension measurements, applied optimize three selected inks. The interplay between tested contact angle measurements comparing biaxial strength cast additively manufactured specimens. Out agents tested, polyethyleneimine phenolic resin have potential their use in LSD‐print bodies, whereas polyacrylate did not show required properties.
