Embodiment Construction

[0076] The created 3D printing method is based on the use of composite fibers ( Figure 1A ). The composite fibers 4 are fiber bundles impregnated with the matrix material 1 and hardened. The fiber bundle may comprise continuous reinforcing fibers 2, such as carbon, glass, aramid, basalt, boron, metal fibers, and functional fibers 3, such as optical fibers and / or conductive fibers, such as copper fibers. The fiber bundle may comprise different numbers of fibers, for example 2, 100, 1000, 3000, 6000, etc. Matrix material 1 for injection is based on phenol formaldehyde, polyester, epoxy, silicone, polyimide, bismaleimide and other adhesive materials, or thermosetting binders with thermoplastic A thermosetting plastic (thermoset) that is a mixture of binders. Thermosetting plastics have good processing properties, especially low viscosity and good adhesion to any type of reinforcing fiber currently in use, allowing good impregnation of reinforcing fiber bundles with the matrix...

Abstract

The invention relates to the field of additive technologies and can be used for manufacturing components and structures made of composite materials. A device comprises an extruder having inlet channels, a heater, a camera, a temperature sensor, a nozzle for material discharge, mechanisms for feeding material and composite fibre in the form of thread, a thread-cutting mechanism, a table and a three-dimensional displacement mechanism. A method comprises manufacturing composite fibre, feeding same and thermoplastic material into the extruder, and heating up the extruder, wherein the thermoplasticmaterial is combined with the composite fibre. The composite material is then extruded onto the surface of the table, where the composite fibre cools and hardens, and the melt of thermoplastic material solidifies, bonding the composite fibres to one another and forming the article. In addition, in the process of forming the article, the composite fibre is cut and the extruder moves on to the nextsection of the trajectory thereof.
