Pop-up ‘origami’ microrobotic ‘Monolithic Bee’ is amazing. Uses laser-cut 18 layer laminate of varying materials to create the body, actuators and assembly scaffold that cunningly folds the dragonfly-like robot into shape with the use of tiny printed hinges.
Incredible 10μm resolution 3D scanning of paintings. Skip to 3:20 to see the incredible sculptural qualities of Van Gogh’s Sunflowers. Technique uses two 40 megapixel DSLRs and a fringe projector (forming a structured-light 3D scanner) to capture the topological map at a resolution of 50μm in the plane of the image and a depth of 9.2μm. Not clear on how they were printed.
Terahertz scanning used to image hidden 3D structures within 3D printed objects by detecting the solid-air interfaces. The system developed by Microsoft Research and presented at Siggraph 2013, can be used to encode identifiers for object recognition, or information associated with the object.
3D printing with non-toxic liquid metal gallium and indium alloy. Printed neat as little droplets or slowly extruded from a syringe, the liquid forms a skin that gives it a little structure. However, if it can be incorporated into plastic and rubber 3D printers then it could provide a way to print electrical circuits within plastic objects and even enable bendable circuits to be created within rubberised materials. Gives another meaning to circuit bending.
