The fabrication of robots and their embedded systems is challenging due to the complexity of the interacting components. The integration of additive manufacturing (AM) to robotics has made advancements in robotics manufacturing through sophisticated and state-of-the-art AM technologies and materials. With the emergence of 3D printing, 3D printing materials are also being considered and engineered for specific applications. This study reviews different 3D printing materials for 3D printing embedded robotics. Materials such as polyethylene glycol diacrylate (PEGDA), acrylonitrile butadiene styrene (ABS), flexible photopolymers, silicone, and elastomer-based materials were found to be the most used 3D printing materials due to their suitability for robotic applications. This review paper revealed that the key areas requiring more research are material formulations for improved mechanical properties, cost, and the inclusion of materials for specific applications. Future perspectives are also provided.

This study posed a solution to the energy concerns that go along with operating a water fountain, especially on providing power for its water pump. Thus, it would allow people to benefit more from the positive effects a water fountain may bring on overall well-being and also on the environment. Applied research was used to come up with the design and implementation of the project. It was presented that the self-sustaining fountain could produce an ample amount of power in which it can sustain its electrical consumption and the excess power can be utilized to light up some light load lightings. The output voltage depends on the magnitude of the flow rate of water, whereas the greater the flow rate of water, the higher the output voltage. Also, this study presented the different factors affecting the output voltage of the self-sustaining fountain such as the addition of loads, transient starting, fumes created by abrupt bubbles, and pressure leakage. Through this innovation, the electrical consumption would indeed decrease of a certain establishment whose sight attraction are ornamental display, moreover, the generation of green efficient and eco-friendly electricity would be practiced and readily available in our society. And certainly, not only small electrical loads would be benefited from this study but also for bigger electrical loads for future exploration and further improvements.
