Description
Summary:The work was devoted to import-substitution of foreign material based on polymer-modified plaster that is used in additive technologies, namely in Binder Jetting technology. Wood-based fibrous material was proposed for use. For this, granulometric analysis of particles obtained from crushing in a mill was performed. Fibrous materials based on beech, oak, larch, alder, and pine were prepared under identical crushing conditions. Pine particles had dimensions most like those of the imported polymer. Scanning electron microscopy of the various types of fibrous materials found that pine and larch particles deviated most from a round shape. Therefore, they would have a low bulk density, which would require more binder for 3D-printing. The fibrous material had a more complicated and developed shape that provided better binding of particles to each other, in contrast to smooth particles of polymer-modified gypsum. This could have a positive effect on the strength of items prepared using Binder Jetting technology.
