FIELD: process engineering.
SUBSTANCE: proposed method comprises selective hardening of powder material layers 3a at points corresponding to cross section of structure 3 in its every layer under effects of electromagnetic radiation 7a. Synthetic powder, preferably, polyamide powder, is used as process powder. Non-hardened powder 3a' is subjected to processing by water or steam at increased temperature and dried for further use in production of another structure. Proposed device comprises electromagnetic radiation source 7, structural chamber 10 with support 2 whereon structure 3 is fabricated and device 5 to apply coating of powder material on said support or hardened layer, device 12 to process non-hardened powder by water or steam.
EFFECT: powder savings, higher ecological safety.
