Comparison of Quality of Investment Castings Produced Based on the Rapid Prototyping Techniques with Products of Powder Sintering

The proposed research work will be related to the comparison of the dimensional accuracy and surface roughness of elements produced by two different methods. Castings are made using modern rapid prototyping techniques and investment casting. For selected parts there will be presented an assessment in terms of manufacturability, design manufacturing costs, operating parameters and energy consumption of production. The analysis of used methods allow for the evaluation of their suitability as alternative manufacturing techniques.
