A new method for creating elements of a heterogeneous detector for sampling-calorimeters of the "Shashlik" type using FDM 3D-printing technology is proposed. An experimental sample was manufactured using the proposed method. The scintillation layers were printed with a filament made of a material consisting of polystyrene with the addition of 2 wt% paraterphenyl (p-TP), 0.05 wt% 2,2-p-phenylene-bis(5-phenyloxazole) (POPOP) and 0.2 wt% dioctyl phthalate. The absorption layers were printed with a filament made of a eutectic alloy (52% Bi, 32% Pb, 16% Sn). The light reflection function is implemented without additional reflective layers due to specular reflection from the metallic surfaces of the absorber. It has been experimentally shown that the proposed method ensures the formation of scintillator-absorber blocks in a single technological cycle. The amplitude spectrum of the response of the printed detector element was investigated. The proposed 3D-printing method may be useful in the development of sampling-detectors with improved energy resolution.
