FIELD: production of composite materials.
SUBSTANCE: invention relates to production of articles by means of additive technologies, in particular, to production of fuel injector. Fuel injector comprises destructible supporting structure for nozzle first and second surfaces opposite in vertical direction. Destructible supporting structure has first base connected to first surface and extending towards second surface, a second base connected to the second surface and extending towards the first surface, and a bridge connecting the first base to the second base. Bridge can be selectively broken under the effect of thermal stress and includes the main part and the weakened zone formed in the said main part.
EFFECT: ensuring absence of product shape distortion and separation of article parts located in close proximity to each other.
