Furthermore, the anisotropic properties of quasicrystals present challenges in achieving uniform mechanical and physical properties in 3D printed objects. The orientation-dependent characteristics of quasicrystals can lead to variations in strength, hardness, and other properties across different directions within the printed structure. Overcoming this anisotropy to produce parts with consistent and predictable properties is a key area of ongoing research.

The limited availability and high cost of quasicrystalline materials also pose significant barriers to their widespread adoption in 3D printing. Developing cost-effective methods for producing quasicrystal feedstock materials in sufficient quantities for large-scale 3D printing applications remains a challenge. Additionally, the need for specialized equipment and expertise to handle and process quasicrystals adds to the overall complexity and cost of implementing quasicrystal-based 3D printing technologies.

Lastly, there is a lack of comprehensive understanding of the relationship between processing parameters, microstructure, and final properties of 3D printed quasicrystalline materials. This knowledge gap hinders the development of optimized printing strategies and limits the ability to tailor the properties of printed quasicrystal objects for specific applications. Extensive research is needed to establish robust process-structure-property relationships for quasicrystal 3D printing.
