FIELD: additive technology.
SUBSTANCE: invention relates to chemically stable sealing components and methods for the production thereof using 3D printing. Chemically stable sealing components may be applicable in vehicles, in particular, to provide a joint between opposite surfaces of parts. Complex sealing components with a smooth surface may be manufactured using co-reactive 3D printing. Method for producing a chemically stable sealing component suitable for sealing opposite surfaces includes: applying consecutive layers of a co-reactive composition of a predetermined shape using 3D printing; and hardening the applied co-reactive composition in order to produce a chemically stable sealing component, wherein the sealing component exhibits the glass transition point Tg when determined by the dynamic mechanical analysis (DMA) method using a TA Instruments Q800 apparatus with a frequency of 1 Hz, an amplitude of 20 mcm, and a linear temperature variation from -80°C to 160°C; wherein Tg is defined as a tangent curve peak δ below -20°C.
EFFECT: production of chemically stable sealing components with smooth surfaces, exhibiting mechanical strength and suitable for effective sealing from the external environment, using 3D printing.
