Abstract

The using of „technical materials” speeded up lately. Because of this, parts are being designed from plastic, which have to sustain extreme stresses. The proper definition of material qualities is expensive; despite in every phase of designing, we need it to be done perfectly. In every industrial section it is important to work with exact material qualities, especially areas where there are strict safety rules (in connection with the lifespan). In this work we will introduce how to design suitable fatigue stress for the plastic samples and how to define the fatigue qualities of the various materials of Rapid Prototyping. This information could be important to change damaged equipments and parts in the military. Due to this, we performed the design of fatigue tests to help the designers elaborate military, safety improvements and proper renewing technologies.

Abstract

Alongside the using of „technical materials’, the direct 3D printed different plastic also speeded up lately. Accordingly to this, it is often designed parts, which have to sustain extreme stress. The proper definition of material qualities is expensive; despite in every phase of designing, we need it to be done perfectly. In every industrial section, it is important to work with exact material characteristics, especially in fields where strict safety rules have to be kept (in connection with the lifespan) the design of fatigue tests of 3D printed polymer specimens. We planned the examinations on the way to avoid the critical temperature range shown by the DMA examinations’ results in the bending point of the inner friction coming up in the local range. This information could be important for the Military to change the busted parts quickly and sound. That is the reason why we designed these examinations in this way, so, it could help for designers in the field of military, in development of security technology and improvement of recovery.
