Polymer tubes as carrier boats of thermosetting and powder materials based on 3D printing for triboelectric nanogenerator with microstructure

3D Printing is one of the few powder-bed type rapid prototyping (RP) technologies, which allows fabrication of parts using powder materials. Understanding of mechanical properties of 3D parts made by this process is essential to explore more applications of this technology. In general, the mechanical properties of many RP produced parts depend on the process parameters andalso on post-processing methods of that RP process. Very few studies have been made to characterize the mechanical properties of 3D Printing processed parts. This paper presents an experimental investigation on how tensile properties of parts fabricated by 3D Printing is affected by 3D Printing build orientation, and by post-processing methods of infiltration process and drying of parts. Results obtained forvarious parameters are compared to investigate the optimum procedure to achieve the highest tensile strength using ZP150 powder material.

Physical Effects

The analysis of the prospects for the use of additive technologies in the production of aerospace equipment has been performed. It is shown that one of the main problems of implementation of these technologies in the main production is the lack of strength and endurance of 3D printing objects. The influence of electro physical effects of varying intensity on the strength properties of the objects from powder materials, formed by 3D printing has been researched. It is found that the electromagnetic field of medium intensity of the investigated range causes an increase in the flexural strength of the plates made of powder Zp130 impregnated with cyanoacrylate Z-Bond TM90, not less than 38%. Thus, a 24% decrease in pore size and reduction in their dispersion by almost 30% is noticed. It is shown that the composite material structure becomes denser with a large number of connections between the agglomerates. The increase in the number of connections, and the increased uniformity of the structure after the electrophysical influence is one of the mechanisms to improve the strength of 3D printed objects exposed to electro-physical influence.
