- abstract = "The main problem of assuring a high dimensional accuracy of rapid prototyping procedures, that are using polymers as a building material, is shrinking of a finished layer during the phase of polymerisation. Therefore, the finished object is slightly smaller then the object's CAD three-dimensional model, that was used to build the prototype. Commonly used method to minimise this problem is to scale (enlarge) the original CAD model in order to compensate for the material's shrinkage during manufacturing. The scaling is usually done by the number factor (in percentages) that is recommended by the rapid prototyping machine's manufacturer. With a long-term use of the certain rapid prototyping machine the end-users can determine their own scale factor's values, which are more suited to their model's properties. This research has established a method that enables the user of a PolyJet RP machine to determine the optimal scale factor regardless of his previous experience. For that purpose the genetic programming methods were used to establish a mathematical model that enables the user to calculate optimal scale factor values for each axis (X,Y,Z) regarding a certain object's properties. This method was later tested on a series of prototypes that were scaled with factor values acquired with the established mathematical model.",
