A material system for use in a 3D-printing, which exhibits a higher form stability. The material system contains binder and solvent as well as optional filler materials. The binder is soluble in the solvent, as well as two complementary polyelectrolytes, and / or an initiator for a cross linking reaction of the binder. The advantage of such a mixed material system is comprised in the essentially higher binder force between the individual particles. This enhanced binder force results either from the acid-base linkages, which form between the complementary polyelectrolytes, or from the supplemental networking initiated by the initiators, or from both. Substantially higher binding forces between the individual particles means at the same time a substantially higher shape stability of the 3D-printing product.

Natural fiber welding
ActiveUS8202379B1Increase material densitySmall surface areaAdhesive processesLaminationPolymer scienceMixed materials
Natural fiber welding is a process by which individual fibers are swollen by an appropriate ionic liquid-based solvent system to form a congealed network. Manipulated fibrous materials may be either composed of natural polymers such as cellulose, hemicellulose, silk, et cetera, or synthetic polymers, or mixed materials. The process is principally controlled by the composition of the solvent system which includes an ionic liquid solvent plus additives such as water, methanol, et cetera. Other conditions such as the amount and placement of solvent, as well as time, temperature, and pressure control the extent to which neighboring fibers are fused. Only the material at the outer surface of fibers need be sufficiently mobile to merge with that of neighboring fibers. Material in the fiber core may be left in the native state by controlling process variables. Fibers form a congealed network upon removal of the ionic liquid-based solvent.
