FIELD: manufacturing technology.
SUBSTANCE: proposed are a three-dimensional sign and its manufacturing method. Three-dimensional sign includes: the upper and the lower units, which are connected to each other; the upper unit includes the main part to reflect the identified shape of the 3D sign; the lower unit comprises a side wall connected with the main part, where the side wall envelopes the main part to support, and a cavity is formed between them, herewith the lower part of the side wall is equipped with a mounting plate, onto which there is a light-emitting element. Between the main part of the upper unit and the side wall of the lower unit there is a connecting part, where the connecting part has the shape of stages and includes multiple stepped layers arranged one onto the other, and each stepped layer comprises a plate of the upper stage and a plate of the lower stage, which are connected to each other, herewith the upper stage plate edge of the lower stepped layer from the multiple stepped layers is connected to the lower stage plate edge of the upper stepped layer connected with the lower stepped layer, and the upper stepped layer connected with the main part has the minimum size, while the lower stepped layer connected with the side wall has the maximum size, and each stepped layer between the upper layer and the lower layer has a larger size than the one located above. Main part is made of plexiglass.
EFFECT: sign has explicitly expressed three-dimensionality, is durable and easily recognizable and using the presented method is simple to manufacture.
