Abstract: A three-dimensional product manufacturing device includes a camera for sensing surface characteristics of a surface layer at the powder bed. A three-dimensional product (3) manufacturing device comprises a work table (2) on which the product is to be built, a powder dispenser (4) which is arranged to lay down a thin layer of powder on the work table for the formation of a powder bed (5), and a ray gun (6) for giving off energy to the powder so that fusion of the powder takes place. Deflection coils (7) control the beam released by the ray gun across the powder bed for the formation of a cross-section of the product through fusion of parts of the powder bed. A controlling computer (8) stores information about successive cross-sections of the product. It is intended to control a mechanism for guiding the ray gun across the powder bed according to a running schedule forming a cross-section of the three-dimensional body. The product is formed by successive fusion of successively formed cross-sections from powder layers laid down by the powder dispenser. A camera senses surface characteristics of a surface layer at the powder bed. An Independent claim is also included for a method for manufacturing the three-dimensional bodies comprising laying down a powder layer on a work table, supplying energy from a ray gun according to a predetermined running schedule for the powder layer, and forming the bodies through successive fusion of successively formed cross-sections from powder layers laid down, and sensing the surface characteristics of a surface layer situated at the powder bed.
