Sažetak
The main applications of the additive manufacturing are in rapid prototyping, for production of different types of prototypes and models. During the last decade, due to advances in fields of materials and technologies, the additive manufacturing has also become a competitive technology for production of tools. The competitive advantage of the additive manufacturing is the possibility to build, in a very short time, complex models with adequate precision. However, besides the precision and the speed of production, the parts produced by additive manufacturing need to satisfy a wide spectrum of requirements concerning their mechanical characteristics. One of the most demanding requests in the tooling production is high surface quality. During manufacturing process arise flaws within the material volume, such as porosities, inclusion, voids and micro-cracks. Later, during the post- processing of the manufactured tools by machining, grinding or polishing, these flaws are brought to the surface of the tool. In most cases, the appearance of the flaws on surface is an undesirable phenomenon in tooling industry, especially for the tools with high-gloss surface. The paper presents a comparison of the surface quality of parts produced by additive manufacturing and parts produced by a conventional technology. The surface quality has been estimated and by visual inspection of surfaces using the microscopy with the aim to study the surface porosity.
