In this group, the following terms or expressions are used with the meaning indicated:
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 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 C04B 35/64). |
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. |
Rapid Prototyping technologies are otherwise known as Solid Freeform Fabrication or Desktop Manufacturing or Layer Manufacturing technologies.
