Rapid tooling refers to process and technologies that help shorten time from planning to producing tools and with which the production costs are reduced. Classic technological procedures, such as turning, milling or casting are still the most common way of producing products from a wide range of available materials; rapid tooling is an option how to make those procedures faster, cheaper and better. On the example of the casting model we present the analysis of time and costs savings between separate procedures of rapid tooling according to classic production of casting application with high-speed cutting.

In this paper we'll present some of the possibilities of the Direct Metal Laser Sintering (DMLS) process with two practical industrial examples. Because short time-to-market and low costs of products are key elements for many companies, we'll present the justification of laser sintering technology for practical Rapid Tooling applications in comparison to High Speed Milling (HSM) together with Electrical Discharge Machining (EDM) and in comparison to CNC process, based on costs and time analysis. Furthermore the Zasavje Regional Technological Centre's marketing strategy for DMLS will be presented. Since there are a number of problems at the introduction of DMLS in the industry, the paper also presents some of the key problems in the marketing of DMLS to the Slovenian industry.
