Beschreibung
Zusammenfassung:	FIELD: printing equipment.SUBSTANCE: invention relates to 3D layered printing. Method includes obtaining a consumable material in the form of a reinforcing material with a coating material located on its surface and the layer-by-layer construction of a 3D model by extrusion of the obtained consumable material. Consumable material is produced by coating with a flux of reinforcing material in the form of carbon fiber, followed by coating the surface of the coating material by pulling it through a bath of molten metal with a melting point lower than that of carbon fiber. Thickness of the coating material is determined as the thickness of the boundary layer, outside of which the flow is disrupted at a given feed rate of the consumable material during extrusion.EFFECT: three-dimensional layered printing is provided by extrusion of consumable material.1 cl, 1 dwg Изобретение относится к 3D послойной печати. Способ включает получение расходуемого материала в виде армирующего материала с расположенным на его поверхности покрывным материалом и послойное построение 3D-модели путем экструзии полученного расходуемого материала. Расходуемый материал получают путем покрытия флюсом армирующего материала в виде углеволокна с последующим нанесением на его поверхность покрывного материала путем протягивания его через ванну жидкого расплавленного металла с температурой плавления, меньшей, чем у углеволокна. Толщину слоя покрывного материала определяют в виде толщины пограничного слоя, за пределами которого происходит срыв потока при заданной скорости подачи расходуемого материала при экструзии. Обеспечивается 3D послойная печать путем экструзии расходуемого материала. 1 ил.
