1. A method of manufacturing an item comprising the steps of:
- controlling a printer (2) to print a layer (9) of retaining material in a predetermined pattern onto a substrate (10) which has registration aids for allowing mechanical indexing apparatus (66) to align the substrates (10) in the X and Y directions;
applying a powder manufacturing material to be retained by the retaining material in substantially the predetermined pattern;
treating the manufacturing material so that it forms a continuous solid piece (7) in substantially the predetermined shape of the pattern, or, where the pattern is made up of distinct parts, in substantially the predetermined shape of each distinct part of the pattern; and
the assembly comprising the solid piece (7) or pieces and the substrate (10) on which it or they is or are formed being used again as the substrate in a subsequent use of the method;
or the solid piece (7) or pieces being separated from the substrate (10).

35. Apparatus for manufacturing an item, the apparatus including:
-
a printer (2) for printing a layer (9) of retaining material in a predetermined pattern;
means (62) for applying a manufacturing material to be retained by the retaining material in substantially the predetermined pattern; and
means (36) for treating the manufacturing material so that it forms a continuous solid piece (7) in substantially the predetermined shape of the pattern, or, where the pattern is made up of distinct parts, in substantially the predetermined shape of each distinct part of the pattern;
whereinthe means (62) for applying the manufacturing material is arranged to apply a powder material;
characterized in thatthe printer (2) is arranged to print a layer (9) of retaining material on a substrate (10) which has X and Y direction registration aids and a mechanical indexing apparatus (66) is provided for aligning the substrates (10) in the X and Y direction; and
means for using again as the substrate the assembly comprising the solid piece or pieces and the substrate on which it or they is or are formed;
or means (51) for removing the solid piece or pieces from the substrate.- View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)
