The emergence of 3D printing technology steers the investigation of new geometric problems. In this talk I will introduce three novel results in the realm of 3D printing and design of geometric models.
The production cost of 3D printing is directly related to the volume of material effectively employed in the printing process. I will present a method to reduce the material cost of a given object while providing a durable printed model that is resistant to external forces.We introduce a hollowing optimization algorithm based on the concept of honeycomb-cells structure.
Next, I will present a technique for designing 3D-printed perforated lamp-shades, which project continuous grayscale images onto the surrounding walls. The spatial distribution of tone across the projection is generated by carefully controlling the amount of light shining through the printed surface.
Finally, I will introduce a novel paradigm of non-realistic 3D stylization, where the expressiveness of a given 3D model is manifested in its 3D shape and structure, rather than only in its rendering. Doing so, we create a stylized and expressive representation of the input that can be utilized in the process of 3D manufacturing.
