Design depends on creativity and innovation in addition to represent possible solutions to design problems to reach the best functional and aesthetic design ideas. However, thinking about design according to the standards and foundations of sciences concerned with studying nature which opens new directions for the textile printing designer and new windows of creativity and innovation based on science to meet all functional and psychological requirements of man. Therefore, modern design trends have emerged based on the study of nature. The science of nature helps the designer to understand the relationships and organizations between natural forms .So we can able to deduce design solutions by applying the standards of these sciences, including biomimicry science, which is a trend that supports advanced technology for the field of textile 3D printing . The problem is how to include the natural sciences, specifically the Biomimetic trend, in the design of 3D textile printing. Significance: 1- Studying the foundations of the biomimicry trend to add another dimension of creativity and innovation to textile printing design. 2- Identifying 3D textile printing as one of the modern methods of printing. Research objectives: - To review one of the modern trends in design and link it to the field of textile printing design. Extracting the concepts of biomicrology to use and link it to the field of 3D textile printing design. - Studying 3D printing as an advanced technology to add a new form to textile printing design. Results: 1- Modern theories create a new window to textile printing design. 2-Linking scientific theories and related scientific knowledge skills to achieve upgrading skills of the textile printing designer. 3- The use of biometric design as one of the trends that the textile printing designer should pay attention to study from a scientific perspective to achieve design solutions and compatible with nature. 4- 3D printing is a rapidly developing technology that a textile printing designer must study to create a design suitable for implementation with this technology. Recommendations: 1- Encouraging designers and students of textile printing design to study the Biomimetic trend as a direction that can be used in the design of three-dimensional textile printing. 2- The importance of inspiring the biology of living organisms and microorganisms in nature, which opens a new field for understanding aesthetic structural systems and achieving sustainability in nature. 3- The necessity of benefiting from modern natural sciences and placing them in the list of basic sciences closely related to design. 4- The necessity of communicating between the results of scientific research and its modern techniques and its rapid development with art and design to open applied plastic approaches with a distinct aesthetic practice in the field of textile printing design. 5- The need to follow the technical and scientific development of printing in its various forms, especially 3D printing, with the need to study it as a scientific method specialized in both its technological and design aspects
