Rapid, low-cost method to 3D print microfluidic devices

Microfluidics is the manipulation and study of sub-microscopic liters of fluids. Technologies that utilise microfluidics are found in many multidisciplinary fields ranging from engineering to biology. Experiments can be performed on a device roughly of the size of a dollar coin, reducing the amount of reagents used, wastes produced, and the overall costs.

Multimaterial 3D printing

Traditional robotic systems with rigid parts often pose a threat to human operators. Recently flourishing soft actuators and robots, in contrast, offer excellent adaptivity to surroundings and safe, coexisting interaction with humans. However, their competence in load-bearing tasks is undermined by the inherent low-stiffness nature of constituent materials like silicone rubbers.

Large-scale, sustainable 3D printing with cellulose

Cellulose is one of the most abundant and broadly distributed organic compound and industrial by-product on Earth. Yet, despite decades of extensive research, the bottom-up use of cellulose to fabricate 3D objects is still plagued with problems that restrict its practical applications: derivatives with vast polluting effects, used in combination with plastics, lack of scalability and high production cost.

3-D printed structures "remember" their shapes

Engineers are using light to print three-dimensional structures that "remember" their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures sprang back to their original forms within seconds of being heated to a certain temperature.
