Multi-shape active composites by 3D printing of digital shape memory polymers
Recent research using 3D printing to create active structures has added an exciting new dimension to 3D printing technology. After being printed, these active, often composite, materials can change their shape over time; this has been termed as 4D printing. In this paper, we demonstrate the design and manufacture of active composites that can take multiple shapes, depending on the environmental...
متن کاملIntegrated Design and Simulation of Tunable, Multi-State Structures Fabricated Monolithically with Multi-Material 3D Printing
Multi-material 3D printing has created new opportunities for fabricating deployable structures. We design reversible, deployable structures that are fabricated flat, have defined load bearing capacity, and multiple, predictable activated geometries. These structures are designed with a hierarchical framework where the proposed bistable actuator serves as the base building block. The actuator is...
متن کاملInstrumented cardiac microphysiological devices via multi-material 3D printing
Biomedical research has relied on animal studies and conventional cell cultures for decades. Recently, microphysiological systems (MPS), also known as organs-on-chips, that recapitulate the structure and function of native tissues in vitro, have emerged as a promising alternative. However, current MPS typically lack integrated sensors and their fabrication requires multi-step lithographic proce...
متن کاملMulti-Material 3D Inkjet Printing - Conductive Paths in Polymer Parts
In this paper the results of a research project that deals with the conceptual design and evaluation of cross-company logistics models are presented. A simulation and evaluation model was designed that supports the development of new logistics concepts. Therefore models for the calculation of emissions, of costs and of logistic competitiveness, have to be created and combined. Based on the sust...
متن کامل3D-printing of lightweight cellular composites.
A new epoxy-based ink is reported, which enables 3D printing of lightweight cellular composites with controlled alignment of multiscale, high-aspectratio fiber reinforcement to create hierarchical structures inspired by balsa wood. Young's modulus values up to 10 times higher than existing commercially available 3D-printed polymers are attainable, while comparable strength values are maintained.
