The repeatability of three-dimensional printers is very important because it determines how accurately a model can be reproduced. Repeatability depends on many factors such as printer quality, software settings, material quality, etc This paper evaluates the repeatability of an Openware desktop three dimensional printers in terms of the resulting standard deviation from a set of samples using a multi-sensor measuring machine. Details with optimal parameters were printed. Statistical analysis was performed on this set of samples. From the statistical analysis of the dimensional deviation data, the repeatability of the printer was analyzed.

“…To achieve the above aim it is necessary to analyze the structure of the measuring equipment under estimation. This equipment is described in details in [7]. Its mechanical module is a hexapod which is actually a closed kinematic chain between the stationary base 1 and the motion platform 2 having six degrees of freedom ( fig.1).…”

“…On the ground of the characteristics of a ship's motion with respect to its six degrees of freedom which must be reproduced by the equipment, we can specify that the most apt variant of its development is using parallel mechanisms (a hexapod of six degrees of freedom). The development of the equipment is considered in details in [7].…”

The present paper views the results related to the solution of a complicated problem in the area of measuring equipment. The proposed mathematical model makes possible the transfer of the measuring unit, the calibration and verification of measuring equipment operating in dynamic mode on the basis of an output measuring instrument calibrated in static mode. The measuring equipment under study is a stand-simulator based on a six-degree-of-freedom Stewart Platform for verifying and calibrating instruments measuring the parameters of a ship's motion. The mathematical model is developed on the basis of the direct kinematics problem of parallel mechanisms.

“…In the classical theory of gear coupling, the parameters of the instrument, which is necessary for the production of the cogwheels of the gear, are accepted as the source parameters for the design. In order to perform geometric synthesis of a single evolvent cylindrical gear, four output parameters are required: Module size -m, Pressure angleα, output contour (loop) displacement factor-x, number of teeth -z [11]. The four parameters determine the axiomatic design of gear mechanisms at known instrument parameters.…”

The article presents specific practical solutions for optimal geometric design of evolvental cylindrical gears with an asymmetric profile of cogs in the context of the basic principle of cog interlocking. In order to achieve unknown until now quality indicators, constructions with a minimum number of cogs and a maximum angle of interlocking are shown, which allow for the production of off-polar gears and significantly increase the gear ratio of the differential and planetary mechanisms. In the process of determining the geometrical parameters of the cogwheels of the gear, the “classical approach” is used by analogy with the parameters of the instrument, necessary for the production of the small-module cogwheels of the gear.
