People are increasingly realizing that 3D printing technology is not only a fun toy, but also can be used at science and technology fairs, according to a report by gascar.The manufacturing process group at the University of Cordoba in Spain studied how to optimize the characteristics of surfaces made using 3D printing technology, with the goal of making such surfaces self-cleaning
The concept of self-cleaning surfaces is not new, as such coatings are already used on glass surfaces in construction and automotive processes, allowing water droplets to easily roll down the surface and remove dust particles.
In some other areas, it is also important to use self-cleaning surfaces.One of them is for traffic lights, where 3D printing technology has already been used to print light bulbs on self-cleaning surfaces.Road safety on highways depends largely on whether such lights are clean enough for drivers to see.So the idea of using rain or morning dew to allow them to clean themselves is very interesting.
The study analyzed the roughness characteristics of 3D printing technology surfaces to allow for less bumps and better finish, to avoid dust embedding, and to allow dust particles to fall off easily.This time, the researchers also looked at the water-repellent properties of 3D printing surfaces, or their ability to resist water.This makes it easier for water to roll down the surface, removing dirt particles and making it harder for dirt particles to stick to the surface.
To implement the study in a practical way, the team created manageable models that predicted the surface characteristics of parts even before they were printed.
In addition to delving into the self-cleaning properties of 3D printing, the project will also focus on improving the surface properties of 3d-printed moulds used to make polyurethane foam components such as car seats, cushions and pillows.In addition, researchers will work to reduce the amount of ice attached to communications antennas and other fuselage components on drones and unmanned aircraft.
