Abstract

In industrial practice, we often encounter a problem when it is necessary to measure and subsequently evaluate the surface quality of the part produced by the water jet, laser cutting. In that case, it is very often difficult to evaluate the final surface because of its weight or bulkiness. However, the literature sources recommend using of material known under the commercial name Dentacryl™. Although this material is still being used in technical practice, its utilisation for creating the replicas of the polypropylene surfaces which is produced by the laser beam is not recommended due to its limited viscosity and mainly due to its health risk for allergic people. Therefore, this article will describe a method of an application the two-component dental material Siloflex^© for the creation of the replicas of polypropylene surfaces formed after CO₂ laser machining. Furthermore, the statistical approach for evaluation of the quality comparison of the original surfaces and produced replicas is necessary to surface quality of produced replicas.
