    Mass spectrometers for space research should be low weight and low power consumption devices. This demand encourages industry to develop a new generation of miniaturized mass spectrometers with better characteristics. Mass spectrometers based on ion trap principles are considered to be the most suitable for miniaturization. One of the types of the ion traps which has not been used so far for space applications is Kingdon type traps. Such traps belong to DC type family of mass spectrometer could have the mass resolution more than an order of magnitude higher than the resolution of the instruments currently used for space explorations. The most attractive is the last member of the family - multi-electrode harmonized Kingdon trap. Mass spectrometers need a vacuum to operate that makes these instruments ideally suited for exploration of space bodies without atmosphere. We are using the Moon environment in our analysis. The main problem of a multi-electrode harmonized Kingdon traps manufacturing is connected to their complicated geometry with lack of rotational symmetry. Additive technologies are appropriate for this case. 3D printing provides probability to meet all requirements of the Ion Trap's manufacturing and even open new opportunities as a quick modification for the new geometries. The goal of this research is to create the high precise 3D model of the ion trap and conduct thermomechanical analysis for the space environment. The results of the research are implemented during manufacturing via high precise metal 3D printing.
