METHOD OF MAKING 3-D PRODUCTS AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2017 - IPC B22F3/105 B22F7/00 B33Y10/00 B33Y30/00 

FIELD: physics.

SUBSTANCE: group of inventions relates to the making of 3-D products from the powder in the form of closed shell with a bottom part. The bottom part is formed on the support, then the outer shell is formed at height from the groups of the layers, wherein each of said groups of layers is formed by means of powder filling layer by layer, its planarization and layered laser sintering of a specified area in the plane of each layer to obtain shells of the given height, after forming of each layer group, the inner cavity of the outer shell is filled with the powder to the height of this layer group and carry out laser sintering of the inside cavity powder of the of said shell to its full depth. The offered device is designed for manufacturing the 3-D product layer by layer from powder by the said method.

EFFECT: invention provides a reduction of time spent for 3-D product creation.
