Abstract
Purpose
This paper aims to relate to the study of mechanical properties of materials used in rapid prototyping (RP).
Design/methodology/approach
Comparison of mechanical properties of commercial RP materials. The study of the literature was the essential source of obtaining the results necessary to complete the evaluations and to determine the property ranges.
Findings
Specifications of mechanical properties collected in one paper about mechanical properties and anisotropy enable to define limitations for prototype properties.
Research limitations/implications
The study is limited to accessible data concerning materials from manufacturers’ offers.
Practical implications
The study is particularly useful in the RP methods application.
Originality/value
The obtained study of mechanical properties makes a quick analysis possible. This article also includes the guideline for design engineers, which determines RP method suitability to create functional prototypes of the machines. Mechanical properties of materials have been adopted as a criterion.

Abstract
Purpose
The main aim of the paper is the application of the selective laser sintering (SLS) method for fabrication of hydrodynamic torque converter (HTC) impellers.
Design/methodology/approach
Establishing of assumptions for the impeller design process based on the HTC characteristics analysis, creation of the virtual solid model of HTC impellers, fabrication of HTC impellers by using the SLS method, investigation of the performance of HTC with fabricated impellers by using a test rig.
Findings
The test results show that the SLS method can be successfully used for the fabrication of HTC impellers with 3D and flat blades.
Research limitations/implications
The method application is limited to small diameters of HTC impellers depending on working area dimensions of SLS machine.
Practical implications
The method can decrease the time and cost of fabrication of HTC impellers by using the SLS method.
Originality/value
The application of the SLS method for fabrication of HTC impellers with 3D and flat blades.
