Through a process commonly known as curing, the liquid is converted to the solid state. Stereolithography: STL. product designer want to have a physical model of a new part of product design rather than just a computer model or line drawing . 2 Principles of Rapid Prototyping. Rapid prototyping (RP), also known as additive manufacturing or three-dimensional (3D) printing, is a group of evolving technologies that create 3D objects additively in a layer-by-layer manner from a predefined 3D computer model. Additive manufacturing technique using three dimensional computer aided design (CAD) data. Based on the type of raw material used for rapid prototyping, additive layer manufacturing processes can be classified as follows: Liquid Based Additive Layer Manufacturing Liquid printing systems begin with a supply of raw material in the liquid phase and using a high energy electron or laser beam to process and cure the material into the final, solid part. Advantages of rapid prototyping Speed. (DSPC) Fraunhofer's Multiphase Jet Solidification(MJS) EOS's EOSINT Systems. The software in the 3D printing machine can read the STL file and based on those small triangles or layers, the machine starts laying off layers of materials, liquid or sheet materials. Liquid-based RP systems have initial form of its material in liquid state. LIQUID-BASED RAPID PROTOTYPING SYSTEMS Starting material is liquid . RP process for fabricating a solid plastic part out of a photosensitive liquid polymer using a directed laser beam to solidify the polymer . Two categories: Removal and addition.
