Abstract

3D printing technology could be an option for the delivery of spare parts in a multinational army supply process, especially in crisis situations, when specific spare parts need to be available as soon as possible. The article deals with the selection of fused filament fabrication as an appropriate method for that purpose by comparing its advantages and disadvantages, as well as the best material (Nylon CF15 Carbon) based on important mechanical properties using the comparative and Saaty's methods. Several samples were made to be exposed to UV radiation in a climate chamber (Q-LAB Q-SUN-Xe3 equipped with a DAYLIGHT-Q filter) and tested according to the ASTM D2565 and ASTM D4459 standards. To compare the mechanical properties of the samples exposed to UV radiation with those of the unexposed ones, a tensile test was done according to the CSN EN ISO 527-2 standard. Finally, the specific spare part was designed and 3D printed, and the delivery times of the standard supply period were compared with those of the 3D printing technology.
