“…Taking time into account as an additional dimension, the process of printing structures that can transform in a pre-programmed way in response to a stimulus is called 4D printing [Tib14]. Several recent works in computer graphics investigated the design of surfaces fabricated with pre-stretched elastic materials that deploy into complex, three-dimensional shapes [GMB17,POT17,KMM17]. Other methods optimize shapes to offer a predefined elastic [CLMK17] or dynamic behavior [UKSI14,BWBSH14].…”

Digital fabrication devices are powerful tools for creating tangible reproductions of 3D digital models. Most available printing technologies aim at producing an accurate copy of a tridimensional shape. However, fabrication technologies can also be used to create a stylistic representation of a digital shape. We refer to this class of methods as "stylized fabrication methods." These methods abstract geometric and physical features of a given shape to create an unconventional representation, to produce an optical illusion, or to devise a particular interaction with the fabricated model. In this state-of-the-art report, we classify and overview this broad and emerging class of approaches and also propose possible directions for future research.

“…In computer graphics, minimal surfaces have been introduced as novel modeling tools for animating dynamic liquid foams (e.g., coffee foam) [29] and double bubbles [30]. Pérez et al [31] explored the Kirchhoff-Plateau Surfaces in the context of fabrication, designed planar rod networks embedded in prestretched fabric that deploy into complex, three-dimensional shapes.…”

3D printed objects are rapidly becoming prevalent in science, technology and daily life. An important question is how to obtain strong and durable 3D models using standard printing techniques. This question is often translated to computing smartly designed interior structures that provide strong support and yield resistant 3D models. In this paper we suggest a combination between 3D printing and material injection to achieve strong 3D printed objects. We utilize triply periodic minimal surfaces (TPMS) to define novel interior support structures. TPMS are closed form and can be computed in a simple and straightforward manner. Since TPMS are smooth and connected, we utilize them to define channels that adequately distribute injected materials in the shape interior. To account for weak regions, TPMS channels are locally optimized according to the shape stress field. After the object is printed, we simply inject the TPMS channels with materials that solidify and yield a strong inner structure that supports the shape. Our method allows injecting a wide range of materials in an object interior in a fast and easy manner. Results demonstrate the efficiency of strong printing by combining 3D printing and injection together.

“…Several works in computer graphics have considered this class of problem, including Kirchhoff-Plateau surfaces [Pérez et al 2017], thermal-formed models [Schüller et al 2016], clothing [Bartle et al 2016;Umetani et al 2011], and plush toys [Bern et al 2017;Mori and Igarashi 2007] all aim at forming given 3D surfaces by assembled flat panels. In particular, Pérez et al [2017] developed an approach to compute an optimized rod network on pre-stretched fabric, which is a similar 2D layout computation problem. However, the inverse design problem of fabric formwork is governed by a different physical model which is challenging because of the variation of fluid pressure with reference to the height and its dependency on fabrication orientation.…”

We present an inverse design tool for fabric formwork - a process where flat panels are sewn together to form a fabric container for casting a plaster sculpture. Compared to 3D printing techniques, the benefit of fabric formwork is its properties of low-cost and easy transport. The process of fabric formwork is akin to molding and casting but having a soft boundary. Deformation of the fabric container is governed by force equilibrium between the pressure forces from liquid fill and tension in the stretched fabric. The final result of fabrication depends on the shapes of the flat panels, the fabrication orientation and the placement of external supports. Our computational framework generates optimized flat panels and fabrication orientation with reference to a target shape, and determines effective locations for external supports. We demonstrate the function of this design tool on a variety of models with different shapes and topology. Physical fabrication is also demonstrated to validate our approach.
