Scope Notes

Glossary: rapid prototyping (RP) rapid prototyping RP RP is a forming method in which resin or powder material is used. RP devices build up a prototype body layer by layer, rapidly generating a three-dimensional [3D] free form. In the ceramic art, two kinds of RP are mainly applied. One is "3D Printing", the other is "Selective Laser Sintering" (see glossary of group ). 3D Printing [3DP] 3D Printing 3DP 3DP is a general forming technique which is also used in the ceramic art, developed from stereolithography. Light-sensitive monomers are polymerised by a laser beam and solidified by gelation in this way. Through the gelation and solidification of an aqueous ceramic slurry, which contains the light-sensitive monomer, a component is built up in layers. | Limiting references: After-treatment of ceramics, e.g. coating or impregnation Articles characterised by particular shape, e.g. linings for casting ladles, tundishes, cups or the like Mechanical features relating to the shaping of clay or other ceramic compositions, e.g. by injection moulding or by slip-casting by applying the material on to a core to form a layer thereon Preparing clay or like ceramic compositions; Producing mixtures containing clay or like ceramic compositions Working stone or stone-like materials Chemical preparations of powders of inorganic compounds
