Özet:

Fused deposition modeling (FDM), one of the most common methods of additive manufacturing, has been widely used in recent years. It is generally preferred in applications for products where high mechanical properties are not required and where visuality is at the forefront instead of functionality. However, as a result of the enrichment of new materials developed for the FDM method with elastomers and composites, different application areas have emerged. This study focuses on the mechanical properties of elastomeric TPU and carbon fiber-reinforced TPU materials in addition to the traditionally used PLA filaments. The compressive strength and relative strength values resulting from the use of different processing strategies and lattice structures were investigated. Thus, lightweight, low-cost, and high-relative strength structures that can be produced in a shorter time with lattice structures and processing strategies have been obtained. Furthermore, compression tests revealed that TPU and carbon fiber-reinforced TPU materials, in particular, returned to their initial geometry with spring back.
