Tuning Pressure Drop in Isoporous Membranes: Design with Fabrication Variability

Ong, S.K., Birgersson, E. and Low, H.Y. (2021), Tuning Pressure Drop in Isoporous Membranes: Design with Fabrication Variability. Adv. Theory Simul., 4: 2100088. https://doi.org/10.1002/adts.202100088 

Abstract

Isoporous membranes consist of well-defined micro and nanoscale pore architecture comprising uniform pore sizes with straight pore channels. In contrast to traditional random porous membranes with tortuous flow paths, isoporous membranes offer the […]

Interchangeable Components for Hands-On Assembly Based Modelling

Interchangeable components allow an object to be easily reconfigured but usually reveal that the object is composed of parts. In this work, we present a computational approach for the design of components which are interchangeable, but also form objects with a coherent appearance which conceals their composition from parts. These components allow a physical realization […]

4D printing of active structures with spatially variable materials

Researchers from the SUTD Digital Manufacturing and Design Centre have developed a novel computational design optimization and manufacturing toolchain for the creation of complex 3D curved rod structures with spatially variable material distributions. These structures exhibit active deformation behavior, which is enabled by the shape memory effect of 3D printed photopolymers – so-called 4D printing.

Plasmonic color printing methods to print onto curved surfaces.

Color printing has historically been achieved through the use of dyes and colorants that are applied onto surfaces. Structural color due to periodic nanostructures that diffract light can also produce vibrant colors, but suffers from color variation with viewing angle. On the other hand, metal nanostructures have been shown to produce resonances in the visible […]

Fill and Transfer: A Simple Physics-based Approach for Containability Reasoning

The visual perception of object affordances has emerged as a useful ingredient for building powerful computer vision and robotic applications. In this project we introduce a novel approach to reason about liquid containability – the affordance of containing liquid. Our approach analyzes container objects based on two simple physical processes: the Fill and Transfer of […]

Functional analysis of a 3D shape

Zoomorphic shapes are man-made shapes that possess the form or appearance of an animal. They have desirable aesthetic properties, but are difficult to create using conventional modeling tools. We present a method for creating zoomorphic shapes by merging a man-made shape and an animal shape. To identify a pair of shapes that are suitable for […]
