FIELD: 3D-printing.
SUBSTANCE: invention relates to a stereolithographic system for layer-by-layer construction of objects. System (1) for forming a three-dimensional component contains tray (13) with at least partially transparent base (23), at least partially stretchable semi-permeable layer (7) for receiving photosensitive substance (5) and chemical substance in the form of liquid or gas (9) located under semi-permeable layer (7). Light source (25) is located under base (23) of the tray for curing photoreactive substance (5) in some areas. Working platform (31) is located above semi-permeable layer (7) with the possibility of lifting and lowering relatively to it to receive component (3) or individual component layers (3i). Semi-permeable layer (7) contains at least one moving element (15) made in the form of elevation (15) passing at least from semi-permeable layer (7) towards working platform (31) and made with the possibility of moving relatively to base (23) of the tray to create the effect of transferring photoreactive substance (5) for its delivery by induced flow into gap (20) between working platform (31) and semi-permeable layer (7).
EFFECT: ensuring a continuous and economical process of forming three-dimensional components.
