Rapid improvements in 3D printing technology bring about new possibilities to print with different types of printing materials. New studies have investigated and presented various printing methodologies. However, the majority of these studies are targeted at experimenting with rigid 3D printed objects rather than soft 3D printed fabrications. The presented research considers soft 3D printing, particularly focusing on the development of flexible patterns based on non-homogenous hybrid honeycombs for the interior of 3D printed objects to improve their flexibility and additional stretchability including the lightweight interior. After decomposing the area of an object into regions, our method creates a specific design where patterns are positioned at each partitioned region of the object area by connecting opposite sides of the boundary. The number of regions is determined according to application requirements or by user demands. The current study provides the results of conducted experiments. The aim of this research is to create flexible, stretchable, and lightweight soft 3D printed objects by exploring their deformation responses under tension, compression and flexure tests. This method generates soft 3D printed fabrications with physical properties that meet user demands. View Full-Text
